Preheat your oven to 400°F and line a baking sheet with parchment paper.

Gently wipe each of the 16 mushrooms clean using a damp paper towel to remove any surface dirt.

Extract the stems from the mushrooms, creating a hollow space perfect for holding the creamy filling.

Finely mince the removed mushroom stems into tiny, uniform pieces.

In a bowl, combine the softened cream cheese, grated parmesan, minced garlic, chopped stems, parsley, salt, and pepper. Mix until smooth and consistent.

Lightly coat the exterior of each mushroom cap with olive oil.

Generously stuff each mushroom cavity with the cream cheese mixture, allowing it to mound slightly above the rim.

Sprinkle breadcrumbs across the top of each stuffed mushroom.

Position the stuffed mushrooms on the prepared baking sheet, leaving small gaps between each one.

Bake for 18-20 minutes until the tops are golden brown and the mushrooms are tender.

Remove from the oven and allow the mushrooms to rest for 5 minutes before transferring them to a serving platter.
