Creating Roasted Mushrooms in a Browned Butter, Garlic, and Thyme Sauce is straightforward if you follow these steps:

1. Preheat Your Oven: Preheat your oven to 400°F (200°C).
2. Prepare the Mushrooms: Clean the mushrooms gently with a damp paper towel. Trim the stems if necessary, and slice them in half if they are large.
3. Brown the Butter: In a skillet over medium heat, melt the unsalted butter. Keep an eye on it as it melts, stirring occasionally until it begins to foam and turn a golden brown color. This process should take about 3-5 minutes.
4. Add Garlic and Thyme: Once the butter has browned, add the minced garlic and thyme leaves to the skillet. Stir for about 30 seconds, until fragrant.
5. Combine with Mushrooms: In a large mixing bowl, toss the cleaned mushrooms with the browned butter mixture. Ensure they are well coated. Season with salt and pepper to taste.
6. Roast the Mushrooms: Spread the mushrooms in a single layer on a baking sheet lined with parchment paper. Roast in the preheated oven for 20-25 minutes, until they are golden and tender. Stir halfway through to ensure even roasting.
7. Finish with Lemon (Optional): If you prefer a hint of acidity, drizzle the roasted mushrooms with fresh lemon juice before serving.
8. Plate and Serve: Transfer the mushrooms to a serving dish, garnishing with additional thyme leaves if desired.

These simple steps will yield beautiful, flavorful Roasted Mushrooms in a Browned Butter, Garlic, and Thyme Sauce that everyone will love!
