Gently wipe the mushrooms with a damp cloth to remove dirt. Avoid soaking them in water, as they can become soggy.
In a large skillet, heat the olive oil over medium heat until it shimmers.
Add the minced garlic to the hot oil and sauté for about 1 minute, stirring constantly.
Introduce the cleaned mushrooms to the pan and stir to coat them with the oil and garlic. Cook for about 5-7 minutes until browned and tender.
Sprinkle salt, pepper, and fresh parsley (or basil) over the mushrooms. Add balsamic vinegar if desired and cook for an additional minute before serving hot.
