Preheat your oven to 375°F (190°C).

Clean the large button mushrooms with a damp cloth and remove stems.

In a mixing bowl, combine minced garlic, grated parmesan cheese, breadcrumbs, chopped parsley, and olive oil.

Mix until well combined and slightly sticky.

Generously fill each mushroom cap with the cheesy filling.

Arrange stuffed mushrooms on a baking sheet lined with parchment paper.

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

Let them cool slightly before serving.
