Follow these simple steps to create delightful Roasted Mushrooms in a Browned Butter, Garlic and Thyme Sauce:

1. Preheat the Oven: Set your oven to 425°F (220°C) to get it ready for roasting the mushrooms.
2. Clean the Mushrooms: Gently wipe the mushrooms with a damp cloth to remove any dirt. Avoid soaking them in water.
3. Slice the Mushrooms: If using large mushrooms, slice them into halves or quarters for even cooking. Smaller mushrooms can be kept whole.
4. Prepare the Baking Sheet: Line a large baking sheet with parchment paper for easy cleanup.
5. Arrange the Mushrooms: Spread the cleaned and sliced mushrooms evenly on the baking sheet. Drizzle with olive oil, salt, and pepper.
6. Roast the Mushrooms: Place the baking sheet in the preheated oven and roast for 15-20 minutes until the mushrooms are golden brown and tender. Stir once halfway through for even cooking.
7. Brown the Butter: In a large skillet, melt the butter over medium heat. Watch closely as it begins to foam.
8. Add Garlic and Thyme: Once the butter starts to turn a light golden brown, add the minced garlic and thyme. Sauté for about 1 minute, until fragrant.
9. Combine: Remove the roasted mushrooms from the oven and transfer them to the skillet with the browned butter sauce. Stir gently to coat the mushrooms evenly.
10. Season: Adjust seasoning with additional salt and pepper if desired.
11. Serve Immediately: Transfer the mushrooms to a serving dish. Garnish with fresh parsley if desired.
