Preheat the oven to 400°F (200°C).
Clean the mushrooms with a damp cloth and remove the stems.
In a bowl, combine cream cheese, Parmesan, garlic, salt, pepper, and green onions.
Stuff each mushroom cap with the cream cheese mixture.
Place the mushrooms on a baking sheet lined with parchment paper.
Sprinkle breadcrumbs on top of the stuffed mushrooms.
Drizzle olive oil over the mushrooms for extra flavor.
Bake for 20 minutes or until the tops are golden brown.
Let them cool slightly before serving to let the flavors meld.
