Step up your side dish game with these quick and easy Garlic Roasted Mushrooms! These savory shrooms are vegetarian, gluten-free, and full of garlicky goodness!

It’s that glorious time of year just before the holiday season madness is upon us.
Granted, I totally welcome this madness with open arms but it’s a loooooot less chaotic if I start planning ahead way before the fact.
This easy peasy mushroom dish has been on my test run list for a while now and I’m so stoked to finally have it in my face and on the blog!
It’s fast and flavorful and honestly, can totally double as an appetizer if you’re bold enough to just dive on in with a toothpick!


Garlic Parmesan Roasted Mushrooms
These mushrooms are a garlic lover’s dream!
Featuring a classic combo of garlic, butter, and optional parmesan, this scrumptious side dish is a welcome addition to your holiday spread and a fabulous weeknight side to pair with your favorite protein and/or pasta dish.
As written, this recipe is gluten-free, grain-free, vegetarian, low-carb, and keto friendly too. Woot!

This recipe yields 4 servings but I’m not going to sit here and pretend that my husband and I didn’t eat the entire pound of mushrooms in a single sitting.
I regret nothing, I tell you! Nothing!
Looking to feed a crowd? Simply double the recipe for 8 side-dish sized servings. If serving it as part of a holiday spread you’ll easily get 12-14 small servings out of the doubled recipe.

Questions & Reviews
These look amazing! Can they be prepared a day before and then reheated?
Thanks Darlene – we love them! I haven’t tried reheating simply because the roast time would be the same as the reheat time unless you were microwaving them? The 20 min roast time is super quick but I’m sure they could be made and microwaved if preferred; the texture will just be a bit different.
This has to be the ultimate mushroom recipe! All of the garlic and parmesan looks awesome!
Oooh, these mushrooms look delicious, especially with the garlic and parmesan! Perfect as an appetizer too, but I think I try these with grilled steak!
OMG this sounds so delicious. Mushrooms and cheese = true love.
They’re BFF for sure! 🙂
Yummy!! My kids would love this recipe! I like how it would make a great pot luck recipe with the holiday coming up ?.
Thank you Stacey! Hope you get a chance to try it soon! 🙂
