Preheat your oven to 375°F (190°C) and prepare a baking sheet with parchment paper.

Clean the mushrooms by wiping them with a damp cloth to remove dirt.

Remove the mushroom stems and finely chop them; set aside.

In a mixing bowl, combine chopped mushroom stems, bread crumbs, grated Parmesan, minced garlic, parsley, olive oil, salt, and pepper.

Stuff each mushroom cap with the filling, pressing gently to pack it in.

Arrange the stuffed mushrooms on the baking sheet, spacing them evenly.

Bake for 20-25 minutes until tender and golden brown.

Cool for a few minutes before serving on a festive platter.
