I promised myself I wouldn’t post this one until I had better photos to share along with the recipe… Then I promptly kicked myself in the face.

Insecurity is so dumb sometimes, especially when it’s over something as trivial as photos for a knockout recipe.

And this dish is a TOTAL knockout. It’s a warm hug on a cold day, a game changing side dish, and proof that cauliflower is so much more than a trendy substitute for white potatoes. When I decided to make a gratin-style casserole with my favorite foodie trifecta (Sriracha, bacon, and cheese, yo!) I literally had no other veggie in mind for the job. Cauliflower for president.

Or something like that.

This Bacon Sriracha Cauliflower au Gratin casserole is a spotlight-worthy side dish that's easy, cheesy, + insanely delicious! -- my family raved about it!

Bacon Sriracha Cauliflower Gratin

I flipping LOVE cauliflower. It’s one of those foods that, though completely devoid in color, is positively bursting with nutrients. It’s a great source of vitamins and is oh so versatile.

Whether you mash it, blend it, or transform it into pizza crust, cauliflower is your guy. He has your back. He… why on earth am I personalizing cauliflower? Now we’ll never be able to eat him… I mean it! Gahhhh you know what I mean!

While I sit in the corner contemplating what I’ve just done, you should march your cauliflower-loving face in the kitchen and make this recipe. Not a fan of cauliflower? Fret not, that’s about to change! This easy, cheesy casserole is about to win you over.

I could wax poetic about how ridiculously tasty it is for hours, but all that’s going to do is turn me into a hungry hungry hippo and delay you from making this dish. So let’s move on to the recipe, shall we?

Author Jenn Laughlin - Peas and Crayons


  • 1 head of cauliflower
  • 4 slices cooked bacon, chopped
  • 1-2 cloves garlic, minced
  • 4 TBSP unsalted butter
  • 1/4 cup all purpose flour
  • 1.5 cups milk or cream (room temp.)
  • 1/4 tsp salt
  • 1/8 tsp nutmeg
  • 1/3 cup grated gouda cheese
  • 1 TBSP Sriracha


  • 1/4 cup grated Gouda cheese
  • a hearty drizzle or two of Sriracha
  • 8-10 crushed buttery crackers or bread crumbs


  1. Preheat oven to 350 degrees F.
  2. Set aside a bowl of water and ice to shock your veggies post-blanching to keep them al-dente. For soft cauliflower you can skip this step.
  3. Cook the cauliflower florets in a pot of boiling water with a pinch of salt for about 5-7 minutes until tender.
  4. Drain and toss cauliflower into the ice bath to halt the cooking process and keep the cauliflower's integrity. We want tender, al-dente cauliflower - no mushy veggies here! Though you can absolutely adjust the texture to your liking.
  5. While it chills, start your sauce.
  6. Melt butter in a saucepan over medium-low heat and add your minced garlic.
  7. Add flour, slowly, whisking constantly to create your roux.
  8. Pour warmed or room temperature milk/cream into the butter mixture and whisk constantly until thickened.
  9. Remove from heat and add salt nutmeg, and 1/3 cup grated Gouda cheese. Stir until the cheese melts into the sauce and add your Sriracha.
  10. Remove your cauliflower from the ice bath with a slotted spoon and move it to a baking dish.
  11. Pour the sauce over your cauliflower and toss to coat.
  12. Top with additional cheese, bacon, and crushed crackers or bread crumbs.
  13. Bake at 350 degrees F for 20-30 minutes until golden and bubbly.
  14. Top with an additional drizzle of sriracha and dive in!

    This is a hit! It may be my favorite way to make cauliflower from here on out. Thanks for the recipe.

  • Debbie Herbert

    My company is having a pot luck lunch, and I would like to bring this dish. We do not have an oven there. Can I make this in a crockpot? Or make it in the oven as directed, and transfer to a crockpot to warm it?

    • Hey Debbie! Cooking it in the crockpot would likely make it so tender it falls apart (towards the soup spectrum) but making it in the oven then keeping it on the warm function in the crock-pot is brilliant! I would totally go that route — enjoy + let me know how it goes! 🙂

  • Jenn, this sounds amazeballs!! I have GOT to give it a try ASAP!!

    • Thanks Bobbi!!! Let me know what you think! I’m crazy about this dish! <3

  • Hi Jenn,
    This looks amazing and I have it bookmarked. The bacon really puts an awesome finishing touch to this dish and reading some of the other comments, I see that you also have a brussels sprouts gratin? I am so there!!

    • Hi Forrest! Thank you!!! I love a good gratin dish, I can’t help but keep making variations. My Winter Veggie Gratin has brussels, broccoli, and cauliflower though the creamy gratin and onion sauce would work great with with just brussels sprouts too! Hope you get a chance to try it out 🙂

  • Briget

    I HATE cauliflower with a passion. I try every recipe I see hoping I will find one I can tolerate. I made this today & fell in love! This was one of the most delicious side dishes I have ever tasted. Thank you so much for giving me a new go to recipe & helping enjoy such a nutritious veggie.

    • Jenn

      Briget you made my day! I’m over the moon that my recipe turned your feelings towards cauliflower around! I felt the same way about a number of veggies for what felt like ages (beets and brussels especially) and fully believe the right recipe/prep/method can make all the difference. Thanks for trying out my recipe and the super sweet comment! I hope you love everything you try on Peas and Crayons <3 XOXO Jenn

    This looks and sounds insane!! I’ll probably adapt to make it keto friendly with a cream cheese sauce of even cauliflower cream sauce to bake it in but this flavor combination sounds insane

  • Lauren

    hey, great recipe! How many does this serve and do You serve it in a casserole dish?

    • Jenn

      Hey Lauren! Thanks! Yes I serve in a casserole/baking dish and it serves 4 standard size portions or 6 smaller portions as part of a larger holiday meal 🙂

  • Kristin

    Finally made this today and it was delicious!

    • Jenn

      Yay!!!! Excuse me while I break out into a happy dance! 😉 Thanks Kristin!

  • My fiancé will go crazy over this dish! We’ve been on a cauliflower kick lately, but he likes his vegetables to be sort of “naughty,” so the bacon will definitely help with that. I’ll let you know what we think 🙂

    • Jenn

      Haha thanks Maren! I hope you both love this sinfully delicious side! The naughty factor is totally what sold my husband too! Can’t wait to hear all about it! <3

  • Holy yum! I’m mad that I missed seeing this recipe for 4 days.
    Cauliflower IS underrated. I love how versatile it is; it’s one of my favorite go-to veggies! I know the bacon-loving hubby would ADORE this recipe.

    • Jenn

      You totally need to make it – we literally cannot stop! One night we attacked the entire dish and just called it a lazy dinner haha <3

  • Oh wow! This looks incredible! Pinning!

    • Jenn

      Thanks Lauren! <3

  • This sounds absolutely delicious.You had me at “add the bacon grease back in…” yes. please. or no.I am not sure that I should, but I think I love this!

    • Jenn

      Thanks Barrie!

  • Sharon

    Where does the garllic fit in?

    • Jenn

      Hey Sharon! Saute it with the butter before adding your flour – hope you get a chance to try it! It’s on the menu again for us this week! Alternatively I’ve also made it without the garlic and used a little garlic powder and it still came out marvelous!

      • Sharon

        Thanks for amending the recipe. I minced it up, but didn’t know what I was supposed to do with it.
        My husband still doesn’t like cauliflower, but *did* like the sauce and thought we should try it on broccoli.

        • Jenn

          Happy to help Sharon! I remember typing the step into the recipe and was like “what?! Where did you go!? nooo!” I just may be losing my mind these days, lol. I’m glad you guys liked the sauce even if it couldn’t swing him over to team cauliflower quite yet. It would be amazing over broccoli! 🙂

  • making this ASAP!

    • Jenn

      Yay!!! Hope you adore it Betty!

  • you are just unreal. Like seriously! can i move in? I need this in my life.

    • Jenn

      I’ll make up the guest room for you and the hubs 🙂

  • This looks delicious. I love cauliflower cheese with whole wheat spaghetti, but bacon and sriracha? That will take it to the next level. Thanks!

    • Jenn

      Bacon and Sriracha are so next level together – thanks Esther!!

  • liviesgram

    This is definitely on my to-make list. But…where do the brussel sprouts come in? I don’t see them in the pic and they are not mentioned in the ingredient list.

    • Jenn

      Oh gosh I’m the worst! I have a brussels sprout and cauliflower gratin too and was updating the directions so they were super detailed – thanks for pointing that out! I’m basically pulling veggies outta my hat here 😉
