• 0.25 cup dry bread crumbs

Steps

1. Preheat the oven to 375 degrees F (190 degrees C).
2. Lightly grease 30 muffin cups with olive oil. Brush all sides mushrooms with remaining olive oil; place gill-sides-up into the prepared muffin cups.
3. Bake in the preheated oven until mushrooms just tender, about 12 minutes.
