Creating perfectly roasted mushrooms is simple if you follow these easy steps:

1. Preheat the Oven: Set your oven to 425°F (220°C) to ensure a good roast.

2. Prepare the Mushrooms: Clean the mushrooms gently with a damp cloth to remove any dirt. Trim the ends of the stems if necessary.

3. Cut the Mushrooms: Slice larger mushrooms in half or quarters to ensure even cooking.

4. Make the Marinade: In a large bowl, combine olive oil, minced garlic, salt, pepper, and thyme.

5. Toss the Mushrooms: Add the cleaned and cut mushrooms to the bowl and toss to coat them evenly with the marinade.

6. Spread on a Baking Sheet: Arrange the mushrooms on a baking sheet in a single layer. Avoid overcrowding to ensure proper roasting.

7. Roast: Place the baking sheet in the preheated oven and roast for 25–30 minutes. Stir halfway through for even cooking.

8. Add Balsamic Vinegar: If using, drizzle balsamic vinegar on the mushrooms for the last 5 minutes of roasting. This will give an incredible depth of flavor.

9. Remove and Garnish: Once golden brown and tender, take the mushrooms out of the oven and sprinkle with fresh parsley.

10. Serve: Enjoy the roasted mushrooms warm, or let them cool slightly for use in other dishes.
