Start by cleaning the chestnut mushrooms with a damp cloth to remove any dirt.

Using a sharp knife, slice the mushrooms evenly.

Place a large skillet over medium heat and add the olive oil.

Add the sliced mushrooms to the hot skillet. Let them cook undisturbed for a few minutes to develop a golden-brown color.

Once browned, stir the mushrooms and add the minced garlic.

Season with salt and pepper to taste.

Once cooked through and beautifully browned, remove the skillet from heat. Sprinkle freshly chopped parsley over the mushrooms.

Transfer the mushrooms to a serving dish.
