To get rid of any dirt, wipe the mushrooms with a moist cloth or paper towel. Slice the mushrooms in half or quarters, depending on size, or leave them whole and trim the stems if necessary.
Prepare the marinade
by whisking together the olive oil, soy sauce, balsamic vinegar, black pepper, thyme (if using), minced garlic, and a pinch of salt in a large mixing bowl.
Marinate the Mushrooms:
Put the mushrooms in a basin and gently toss them in the marinade until a good coating forms.
Give the mushrooms at least 15 to 20 minutes to settle and marinade. To allow the flavors to infuse, you can marinate them for up to an hour if you have extra time.
Preheat the oven
to 400°F (200°C) in order to roast the mushrooms.
Arrange the marinated mushrooms in a single layer on a baking sheet.
In the oven, roast for 20 to 25 minutes, stirring occasionally. The mushrooms ought to be caramelized, soft, and golden.
