Aiming to eat more veggies? This Cheesy Garlic Parmesan Spinach Spaghetti Squash recipe packs an entire package of spinach swirled with an easy cheesy cream sauce.
I’m a really big fan of using an entire package of fresh spinach in a single recipe.
Whether it’s on a tasty flatbread pizza, stuffed into peppers, tossed into a healthy salad, or swirled into an easy cheesy dip, I feel an epic sense of accomplishment if I can fit the entire package into my face somehow.
Not that spinach ever really goes to waste here, but there’s much less margin for error if you use every little bit of that box-o-spinach.
No stray leaves to accidentally forget about, no 1/4 empty box taking up precious fridge space, and no baggies of spinach growing legs next to that partially chopped onion you also forgot about… haha not that I would know from experience or anything.
Ok fine, I’ve totally been there! We all have, right?
Besides, if you use the whole package you not only make Popeye proud, but I’m sure your parents can somehow sense that you’re eating a whole boatload of veggies and are super duper happy about it.
Do it for the parents! Eat all the spinach!
We can start with this easy cheesy stuffed spaghetti squash. YUM!
Cheesy Garlic Parmesan Spinach Spaghetti Squash
Mouthful of a title. Mouthful of deliciousness!
Okay that was excessively cheesy, even for me! My apologies.
Please forgive me and make this easy cheesy stuffed squash the second you step foot in the kitchen. Pretty please? With Parmesan on top!
Cheesy Garlic Parmesan Spinach Spaghetti Squash
This crazy delicious garlic parmesan spaghetti squash is one of the most popular recipes on Peas and Crayons — and for good reason too!
Ingredients
- 1 medium spaghetti squash (approx. 2-3lbs)
- 2.5 TBSP minced garlic
- 1 tsp avocado oil or olive oil
- 5 oz fresh spinach chopped
- 1/2 cup heavy cream
- 1 TBSP cream cheese (optional but delicious!)
- 1/2 cup freshly grated parmesan cheese plus extra for topping
- salt and pepper to taste
- grated or sliced mozzarella for topping to taste
Instructions
-
Pre-heat oven to 400 degrees F.
-
Slice your spaghetti squash in half lengthwise and scoop out the seeds.
-
For easy cutting, feel free to stick your squash in the microwave to soften it up just a tad. Pierce it a few times with a knife (to help vent so it doesn’t burst) and cook for for 3-5 minutes. The knife slides through way easier this way! Smaller squash will need about 3 minutes while larger ones will be good to go at 4-5 min.
-
Next grab a lipped baking sheet or a rimmed baking dish.
-
Rub the cut side of the squash with a teeny bit of olive oil and place on your baking dish/sheet cut side down. Roast for about 40 minutes, or until tender and easily pierced with a fork. Cooking time will vary a bit depending on the size of your squash, and larger squash will need to roast a bit longer to tenderize. Once ready, the once rock-hard exterior of the squash will be visibly softened with a tender interior.
-
The squash can be roasted and stored in the fridge for a few days if you’d like to meal prep and plan ahead for a speedier dinner.
-
While the squash roasts, start on the sauce.
-
In a medium pot or skillet, bring a drizzle of olive oil to medium-high heat and sauté garlic until fragrant.
-
Next add the spinach and stir until wilted. Add your cream, cream cheese (totally optional but totally tasty) and parmesan cheese and stir well.
-
Season with salt and pepper to taste and remove from heat.
-
Once squash is done roasting, allow to cool until easily handled or pop on an oven mit and use a fork to separate and fluff the strands of spaghetti squash.
-
Pour your sauce over each squash boat, stir to mix, and top with a little mozzarella cheese and additional parm cheese, if desired.
-
Bake at 350 degrees F for around 20 minutes or until hot and bubbly.
-
For a golden cheesy topping, flip your oven to broil on high for just a minute or two until lightly browned. Dive in while it’s HOT!
Recipe Notes
T-REX CHEFS: Feel free to add chicken if you’d like! Stir it in with the sauce and veggie noodles or serve it up on the side. Grilled, roasted, baked, poached, rotisserie… anything goes! Shrimp is also a tasty addition to the squash.
Recipe yields 4 servings (so about 1/4 a spaghetti squash per person) as a side dish or it can be split into 2 portions (half a squash per person) as more of a main course, especially if you’re adding extra protein and/or veggies!
Nutrition facts below are an estimate provided by an online nutrition calculator, estimate calculated before mozzarella topping <– add as much or as little as you’d like!

Short on time? Roast it in advance! When I’m making them ahead of time I under-bake the squash by about 5-10 minutes and then finish them off with the easy cheesy filling when we’re ready to eat!
so . . . how was it?!
This easy cheesy spaghetti squash was deliciously dreamy! The creamy parmesan sauce basically turned the tender spaghetti squash strands into the most luscious Alfredo. Throw in some savory sautéed garlic and spinach and we have some serious magic going on here.
“I’m in love! I’m in love, and I don’t care who knows it!”
I’m perpetually looking for ways to get my oh-so-skeptical husband excited about having spaghetti squash for dinner and this recipe totally did the trick!
The first time I tested this Cheesy Garlic Parmesan Spinach Spaghetti Squash I made it around lunchtime and told him he could have *just one bite* of my precious lunch. Next thing I know he’s leaning over, mouth open, begging for another bite. And another. And another…
VICTORY!!!
Jeannette
So far, I have only tried your super good vegetarian lentil tortilla soup and this amazingly beyond “delicious “ squash, but I signed up to “follow “ you and I am so looking forward to trying more recipes. Thank you very much.

Made this for dinner last evening I doubled sauce. Something. I learned this week instead of scraping the spaghetti squash long ways scrape the short sides.
Anyway was very good my husband liked it also.
Denise
Made this as a side dish for myself because my husband doesnt liked squash…well needless to say we both cant get enough of this dish! I’m making it as a side again this weekend with some ribs for a family gathering. So delicious and that’s an understatement.
Jenn
Haha yay!! I’m so glad you both loved it! I did the same with my husband too – I thought now way is he going to eat this and then he ate like half my serving, lol
Robert J Murphy
It looks delicious! Can this be done in a Ninja Foodie?
Jenn
Thank You Robert! I unfortunately do not own a Ninja Foodie (there are so many fun appliances out there!) so I wouldn’t be able to test it out and see. Let me know if you get a chance to experiment! xo

How many carbs
Jenn
Hi Norma! The exact carb count for will vary depending on size of squash used. I believe each cup (101 grams) of spaghetti squash has 7g of carbohydrates with 5.5g net carbs. Myfitnesspal.com has a wonderful calculator so you can add the weight of your squash in and also how much cheese chosen to add on top – this way you have a custom and more accurate measurement to go by if you are committing to set carbohydrate intake. Hope this helps! xoxo
Barb
I made this over the weekend for my husband and sister. Everyone agreed it was a do over!! We had two medium squash. Cut in half and left an extra boat for extra shreds. I also served a side of ground pork sausage sauteed with chopped onion. We kept that on the side and added it to our individual boats. It was delicious.
Penny
FABULOUS! I added extra cheese because we love cheese!
Nikki
This is favorite in our house. My 17 year old daughter requests it often and takes leftovers to school for lunch. I usually add mushrooms and sometimes chicken or sausage. Thank you for a great recipe. Making it tonight again and my daughter can’t wait to get home from practice for dinner 😊
Vanessa
This was absolutely delicious! Made the recipe exactly as is and everyone loved it!
Melissa
I really loved this! My 89 year old mom -not so much! She’s so picky! I’m having leftovers tomorrow! I only used 1/2 of the squash-I would probably double “sauce” next time.
Bethany
I’ve roasted the squash early but want to make it for dinner tonight. Do I need to shred the squash before storing in the fridge until I make dinner or wait?
Also, how do I reheat the squash when we are ready to make dinner??
Excited to try this!!!
Jenn
Hi Bethany! I like to shred it straight from the oven and then either reheat in the oven at 350 or microwave until hot and steamy. The oven will give a little crisp to the noodles while the microwave will keep the strands soft, if you have a preference. xoxo
Jenna
There’s an ad that pop up right in front of the last step. All I can see if put in oven at 350 for 20 mins and then flipping oven to broil..but what does it say in between that? Thanks!
Jenn
Eek it must have glitched – so so sorry about that!
13. Bake at 350 degrees F for around 20 minutes or until hot and bubbly.
14. For a golden cheesy topping, flip your oven to broil on high for just a minute or two until lightly browned. Dive in while it’s HOT!
Kimberly Mayo
I made this today and it was awesome!!! We aren’t HUGE garlic people, so I did change the amount to 1 Tbsp instead of 2.5 and I could still taste the garlic! Everything else was exactly as written. Thank you for sharing! It was very tasty, not that difficult and both hubby and I said we would DEFINETLY eat it again!
Christy
Love it and so do my kids!
Angela
This was amazing! I made some substitutions and additions. I added red crushed pepper as I was sautéing my garlic. I also added mushrooms and artichokes! Instead of cream I used plain Greek yogurt. I wish I had a slice of crusty Italian bread for this recipe! Thank you!
Susan
Plain Greek yogurt is just the substitution I was looking to see if anyone had tried. Thrilled to hear it worked.
dale selden
Made it, Loved it.
Jenn
Yay!!
Jill Van Vleet
The flavors in this recipe are mild and blend well. I added some chicken and green Chile and my family absolutely loved it! Definitely a keeper!
Shelly
This is a delicious recipe. I’m new to spaghetti squash and was worried my husband would not be interested, but we both loved this recipe. I’m making it for a second time tonight. We live it with grilled chicken!
Judy
Just made it my family love it
Thank you
Beverly Noland
This was wonderful! After cooking the squash/ I removed the “spaghetti” and placed in the bottom of a casserole dish and topped with creamy spinach mixture. Then added the mozzarella and baked/ broiled as directed.
Kristine
What a great idea! Seems easier than dealing with the squash boats!
Jackie
I made this tonight for my husband and I we love spaghetti squash and it turned out perfect I added fresh basil cuttings as a garnish. The only problem I had was the Parmesan cheese coagulated when I added it to the hot sauce it seemed to melt out after I added it to the squash dish will definitely make it again
Stefanie Wilson
So very yummy! I have never eaten spaghetti squash before and this was my first recipe using it. So easy, so much flavor!
Nancy
I made this and it was a hit! I added a few sliced grape tomatoes and it was perfect.
Love this. Thank you!!
Hillary
Can you make this with frozen spinach?
Jenn
Hi Hillary! Yes absolutely. Make sure you thaw or warm it up first and then thoroughly squeeze out all the liquid so your sauce is thick and not runny. It will have a different taste (as frozen spinach tastes a bit different than fresh) but I personally love the taste of frozen spinach!
Denaeuh
Really enjoyed this easy dish. I added broccoli as well. Very easy “Alfredo” style sauce.
Cecilia
So yummy and smells delicious every time I make it
Jenn
So happy to hear you’ve been enjoying it, Cecilia! Thank you!
KIMBERLY L BARNES
I have made this recipe twice!! Me an my son are in love!!! We had this for dinner last night and my best friend joined us. She loved it as well and wants the recipe 😋😉. It is so easy to make. I am very thankful for the tip to microwave it for a few minutes before cutting, it worked perfectly.
Jenna
Love this recipe! We did light cream instead of heavy cream, added onions and shrimp! Soooo yummy!
Anita McClelland
I love this recipe!!!! I ended up using a 16 oz bag of spinach. I did simmer the sauce for approximately 15 minutes to reduce it. I will make this again and again and again!
Ben Myhre
We make fun of spaghetti squash, as we can never seem to find great recipes, but I think we found one! lol. As long as the CSA or volunteers from our compost pile produce some of these, we will eat them. I am glad we found this recipe
Sarah
So amazing!!! Cheesy, warm and satisfying. Super easy to make with perfect instructions. Personally I doubled the spinach (I love spinach) and was very happy with the results. This was the second time I had ever cooked spaghetti squash and I really appreciated all the tips.
Thank you!
Ashley Krause
Totally in love with this dish. I made it yesterday. It’s most certainly a keeper!!
Jenn
Yay!!! Thank you Ashley!
Patsy Parkes
This looks like a good keto recipe and would love to have the carb count posted in this recipe as well as any others that would provide low carb counts. Keto is the way to go these days and am working hard to keep my husband on board in order to have him lose weight. So far so good. Thank you for considering this addition to your fabulous recipes.
Jenn
Thank you Patsy! The carb count for keto will vary depending on size of squash used. I believe each cup (101 grams) of spaghetti squash has 7g of carbohydrates with 5.5g net carbs. Myfitnesspal.com has a wonderful calculator so you can add the weight of your squash in and also how much cheese chosen to add on top – this way you have a custom and more accurate measurement to go by! xoxo
Heather Wagner
I added kielbasa and, because I used half and half instead of heavy cream, I doubled the amount of cream cheese. I didn’t have any spinach, so I chopped up a frozen bag of brussel sprouts. I had to add a little more salt to compensate.
My super picky 8 year old (who HATES veggies) gobbled it up and called it delicious! Definitely a WIN for this mama.
Mallory
Our new family favorite go to dinner!!
Shannon
This is my absolute favor way to eat spaghetti squash now, it’s so yummy and satisfying. It’s easy and delicious. Make it, you too will have a new favorite.
Shannon
Seriously amazing. I’m putting this in my rotation for go-to meals. I used way more garlic because that’s how we roll. Also decided to throw this in a casserole dish instead for easy leftovers. Not as beautiful a presentation- but holy moly this was the bomb!
Jenn
Yesssss! The more garlic the better (I’m totally team use the whole darn thing sometimes, haha!) I’m so glad you’re loving the recipe, Shannon. Thank you!
Anita Voluntad
Made this twice and delicious! The first time, I followed the recipe except to use half and half instead of heavy cream. The second time, I used half and half and added a box of sliced shiitake mushrooms before adding the spinach. So good if you like mushrooms! Thank you so much for the recipe. I love your site!
Jamie
ITS SO GOOD. Husband went back for seconds, so that’s a good sign 🙂 I added chicken and skipped the baking because it was late. Delicious!
KimS
Really, really good! I used what I had—neufatchel (low-fat cream cheese), a mixture of half and half and Greek yogurt. Still nich rich flavor. A great complement to the spaghetti squash!!
Rachel Levitt
Made these last night and they were awesome! I doubled the recipe so there could be leftovers (interestingly enough, it still takes about 45 minutes to cook two squashes instead of 1). I added some chopped rotisserie chicken during the final bake. The sauce was great, kind of like an Alfredo. I think next time I’ll cut down on the heavy cream though; it was quite rich. My husband and I loved it, the toddler liked the cheese melted on top so I’ll call that a win too 🙂
Jenn
I’m so glad the recipe was a hit, Rachel! The sauce def has that Alfredo vibe to it and I think you should be able to cut some of the cream out and still have excellent results. The consistency will be a little different so keep an eye on the sauce and adjust where needed. Sometimes I just add loads of extra baby spinach and call it a day lol.
Susan
Can this be made with packaged frozen squash? If so, how many ounces?
Jenn
Hi Susan! Does spaghetti squash come packaged and frozen (I haven’t seen it yet but that’s probably bc I run through the grocery store so fast these days lol) or are you planning on using a different variety of squash? For this recipe I’ve only made it fresh and love the nutty flavor from the freshly roasted squash.
Genevieve
This is an awesome recipe! Honestly, you need to try it! Delicious! Thank you!
Jenn
I’m so stoked you’re loving it Genevieve, thank you!
Mayme
Made this tonight. It was delicious. I would definitely double the sauce, because if you have a larger squash, you need more sauce for it. I gave half to my neighbor and she shared it with her husband and kids and everyone their loved it as well. Definitely a keeper recipe.
Jenn
Great tip, Mayme! You can absolutely double the sauce for larger squash and in the event you make too much sauce, it’s AMAZING drizzled over a baked potato or swirled into pasta. xoxo
Brittney
Love this recipe, but instead of spinach, I use broccoli! Kids love it!
Jenn
Such a fun swap! I love broccoli with spaghetti squash!
Melissa
I doubled the sauce because it’s that good!! Will surely make again and again. I ended up cracking my squash as I cut it so after the squash baked, I shredded it into a casserole dish and added the sauce and cheeses on top and baked 30 minutes more. Everyone loved it!
Jenn
I’m so glad you loved the recipe, Melissa! xoxo
Carly
ABSOLUTELY DELICIOUS! My dad even liked it and he does not like cream cheese!
Made some changes just because of what I had on hand:
1. Added mushrooms at the time of spinach.
2. Used 2% milk – just added until it was the thickness I liked.
3. Herb and Garlic Cream cheese instead of regular – very good!
4. Premade the spaghetti squash, forked it, and stored it in the fridge, in a colander, to allow the water to drain overnight. Next day, prepared the rest and then placed the mixture with squash in a pyrex pan in the oven for the recommended 20 mins at 350F. Turned out just as good as when I made it within the squash halves as per recipe (I have made the recipe twice also far).
G Veches
Made for dinner tonite. Used kale instead of spinach. I thought it, was quite good! Would have liked a bit more sauce, will adjust next time. Great veggie dish. Thanks!
Jenn
I’m so glad you enjoyed it! Sometimes I get naughty and completely double the sauce recipe so I have extra for the squash and then some to drizzle some on baked potatoes the next day – SO GOOD!
Danielle Sherman
LOVE this recipe!! I used light cream and no cream cheese and it was still heavenly. A new staple in my house!!!
Rita
Never had spaghetti squash before. Never knew what I was missing!! My husband loved it! Definitely a keeper.
Jenn
Yay!!!! Thank you Rita!
Colleen
Made this and loved it!
Planning to make it again – but what can I add as a side dish??
Spinach salad – it already has spinach!
Caprese – it already has mozzarella, and that’s a lot of cheese (although, I like cheese)
Other vegetables – it is a vegetable…
I’m truly stumped, or very not creative!
Jenn
So glad you’re loving the recipe, Colleen! Woot! I may win award for most boring side ever but I adore roasting up a tray of seasoned broccoli (salt, pepper, and a little avocado oil drizzle) to serve as a side with this. It makes me feel extra healthy haha. You could also do roasted carrots or fresh baby carrots and dip. A plain green side salad with spring mix or romaine, shredded carrots, halved cherry tomatoes and your favorite dressing would be great too! Hope this helps. xoxo
Sue
Added sauteed mushrooms and raw shrimp. Used onion and chive cream cheese. Baked for 20 minutes, then topped with panko, remaining parmesan and butter, baked additional 10 minutes, then broiled to brown topping. Delicious!!
Julie
This is one of our favorite recipes that is on a regular rotation for our dinners! So delicious! (We always add the cream cheese- it’s so good!)
Brittany
This was sooooo good! Such a nice blend of the garlic, cheese, and spinach. I am def making again!
Amanda
This recipe turned out AMAZING!
Reyna
I love this recipe! I really like to load it up with sundried tomatoes, mushrooms, chicken, and crushed red peppers! I have found my one true love! Thank you for introducing me to spaghetti squash!!!
jessica chiang
delicious!
I scooped out the spaghetti squash and put it in a casserole dish; mixed it with the spinach cream sauce and put pieces of prosciutto on top and topped it with cheese, as instructed.
Thank you for the recipe. it was great!!
Cortney
I love this!
Lori
I have always wanted to try spaghetti squash but figured I’d hate it. OH MY GOODNESS!!!! This was BEYOND yummy!!! So delicious even my picky vegetarian was excited!!! I added sausage to mine crumbled and browned. This was AMAZING!!!! Thank you so much!!!!
Jenn
I’m super stoked you enjoyed it Lori!
Melissa
Delicious! Made exactly as directed. My family is addicted. This recipe is a keeper.
Kim R
This was so delicious! I substituted Greek Yogurt for the heavy cream which also added 17 grams of protein. I didn’t have fresh Parmesan cheese so I added Cotija Cheese instead. I also added 2 TBS of Nutritional Yeast for more flavor and protein. Thanks for a great recipe. This is a keeper!
Jeanie Bone
This was one of the best recipes ever! I really didn’t expect it to be so delicious. I pretty much stuck to the recipe except I didn’t use garlic but instead used garlic infused oil.
Jenn
That garlic infused oil sounds delightful! So glad you enjoyed the recipe Jeanie – thank you!
Claire
Very good…..I added peas, mushrooms, and diced chicken and had a one pot meal. I also put it into a casserole dish and reheated it that way. This recipe is a keeper!
Jennifer
Made this last night and it was Ah-maz-zing!!!!! Definitely a keeper!!
Leigh
Can this be made ahead of time and/or instead of boats use a casserole dish?
Jenn
Hi Leigh! Yes absolutely! The squash soaks up some of the sauce if you want to make a little extra to compensate but either way it’s super yummy! xo
Lois
OMG! This is one of my go to dinners! I make it at least twice a month! It’s so good! And I have leftovers for lunch the next day!
Jenn
The leftovers make me so giddy, haha! Thank you Lois!
Jul Eschrich
Oh my gosh this was so good!!! My husband has to eat meat, so I added a salmon fillet on top of the sauce with a little olive oil and fresh lemon. Then added the final cheese toppings. The salmon came out cooked perfectly and was so flavorful and moist. I did not have any fresh spinach, so I used a half package of frozen well drained spinach. Thanks for the great recipe it is a keeper in our house!
Brenda
This was so good, I even added shrimp & scallops to it.
Thank you
Sally
This was amazing! My husband, who normally doesn’t like spaghetti squash, loved it and has asked me to make it again.
Thank you for sharing!
Alicia Rogers
Yum! I switched it up a little bit. I added broccoli instead of spinach ( didn’t have spinach on hand) added a healthy dash of ground red pepper in the cheese sauce and I added chicken”bacon”. So good!!
Dana Murphy
And my husband AND children like meat so I actually cooked up some Italian sausage and put in in the sauce/stuffing…..??
Dana Murphy
Love Love Love!!!!! My squash skin turned out a little browner than the one in your pic but OMG!!! I seriously don’t think it could get any better!! And I’m pretty sure that anyone that hasn’t tried (or won’t try) spaghetti squash would fall in love…. Jared to mess up and I made this for dinner tonight and actually worked way later than I expected so didn’t think we would actually get to eat it tonight but …??????
Karen
Absolutely delicious! Even my picky husband enjoyed.
Jenn
Woot! Thanks Karen!
Alex
SO GOOD! I made this for my husband and I after we got a couple fresh spaghetti squash from the local pumpkin patch, and it was absolutely amazing! I did add some cubed chicken strips to get the extra protein. I also used a whole, 9oz bag of spinach because I too hate to leave bags partially used 😀 We got two spaghetti squash and my husband said tonight he wouldn’t be mad if I made this again with the other one, I’d consider that a success! Thank you for the great recipe, it’s a keeper!
Jenn
Yay!!! Loving the extra spinach and protein added and I’m so stoked y’all enjoyed it. Thanks Alex!
Trisha
This is so delicious and easy to make. I added sun dried tomatoes and fresh basil to mine and it was amazing. Thank you for the recipe!
