Clean the mushrooms with a damp cloth and remove the stems.
Drizzle olive oil over the mushrooms for extra flavor.
In a bowl, combine cream cheese, Parmesan, garlic, salt, pepper, and green onions.
Let them cool slightly before serving to let the flavors meld.
Place the mushrooms on a baking sheet lined with parchment paper.
Preheat the oven to 400°F (200°C).
