Toss the mushrooms – Begin by placing your cleaned mushrooms in a mixing bowl. Add one tablespoon of oil, along with salt and pepper to taste. Gently toss until coated, ensuring every mushroom shines with flavor.
-
Roast the mushrooms – Spread the prepared mushrooms in a single layer on a baking sheet. Roast them in a preheated oven at 400°F (200°C) for about 20 minutes. Give them a stir halfway through to promote even caramelization until they are golden brown and tender.

Expert Tips for Roasted Mushrooms
-
Mushroom Selection: Choose fresh, firm mushrooms. Avoid any that are slimy or wrinkled, as they won’t roast well in your roasted mushrooms in a browned butter, garlic, and thyme sauce.

Even Cooking: Spread mushrooms in a single layer on the baking sheet. Overcrowding can lead to steaming instead of roasting, preventing the lovely caramelization.
-
Watch the Butter: Keep a close eye on your butter while browning. If it burns, it will taste bitter; a golden hazelnut color is what you’re aiming for!
-
Enhance Flavors: Experiment with adding different herbs or spices in the browned butter sauce. For a kick, try red pepper flakes or fresh parsley.
-
Leftover Use: Use leftovers as a topping for pasta or as a delicious addition to an omelet. It’s a great way to enjoy these roasted mushrooms again!
