  • 32 oz mushrooms cremini or white button
  • 4-6 TBSP unsalted butter
  • 6 cloves fresh garlic smashed and finely minced
  • 1/2 tsp dried oregano
  • 1/4 tsp dried basil
  • 1/4 tsp dried thyme
  • 1/4 tsp allspice
  • 1/8-1/4 tsp black pepper
  • salt to taste (see note below)
  • 2-4 TBSP grated parmesan cheese
  • optional chopped fresh parsley and/or thyme for a burst of color
  • optional crushed red pepper flakes for some fiery heat


  1. Pre-heat oven to 400 degrees F.
  2. Melt butter and add your smashed/minced garlic. Set aside.
  3. Trim the stems and clean mushrooms by wiping with a slightly damp paper towel. (Washing in water can cause them to soak up water and become soggy) I kept my mushrooms whole here but *totally* feel free to halve or quarter them if you prefer! If I have a few spare seconds I’ll cut mine in half.
  4. Line mushrooms in even layer atop a rimmed baking sheet and drizzle with garlic butter, tossing to coat.
  5. Season with oregano, basil, allspice, thyme, salt and pepper. Short on spices? Feel free to season with your favorite Italian seasoning blend (adjust s+p to taste based on the blend you choose)
  6. Roast for 20 minutes or until tender and golden. Add any additional seasoning you’d like and sprinkle with parmesan cheese.
  7. Dive in while they’re hot! 

Recipe Notes

Salt tends to be a very personal matter with recipes so I’m going to let you feel this one out based on preference.

I used unsalted butter and added around 1/4 tsp sea salt to my mushrooms. There’s also a saltiness to the parmesan cheese so keep that in mind while seasoning and you’re good to go!

Garlic Parmesan Roasted Mushrooms

This recipe easily serves a crowd at about 8-10 servings but I’m not going to sit here and pretend that my husband and I didn’t eat the entire 2 pounds of mushrooms in a single sitting.

I regret nothing, I tell you! Nothing!

    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.
