  • Mushrooms: I highly suggest choosing a medley of mushrooms! I went with white beech, cremini mushrooms (also called baby bellas), and shiitakes. Trumpet and white button mushrooms would also be good.
  • Olive Oil drizzled over the mushrooms
  • Salt and Pepper to season
  • Thyme: Toss fresh thyme with the mushrooms and save some for garnishing. You can use other fresh herbs like parsley or fresh chives.
  • Parmesan and Balsamic Vinegar: A sprinkle of good-quality parmesan and balsamic take these mushrooms over the top!

How to Roast Mushrooms

  1. Season the Mushrooms: Divide the mushrooms evenly on the baking sheet sprayed with oil. Toss each with olive oil, salt, pepper, and thyme, and spread the vegetables in an even layer.
  2. How Long to Roast Mushrooms: Bake the mushrooms for 20 minutes at 400°F until tender. Halfway through, stir them and rotate the pans in the oven.
  3. Garnish: Top the mushrooms with parmesan, balsamic vinegar, and thyme.
