Preheat the oven to 375 degrees.
In a small bowl add a package of softened cream cheese. Sprinkle on top the garlic powder, salt and pepper, and dried parsley.
8 ounces cream cheese, 1 teaspoon garlic powder, 1/2 teaspoon salt, 1/2 teaspoon black pepper, 1 teaspoon dried parsley
Use a knife to stir everything together.
For the mushrooms, use a lightly wet paper towel and remove any debris from the mushrooms.
12 ounces whole white mushrooms
Remove the stems so that there is a well in the center of the mushrooms.
Use the knife to scoop the cream cheese mixture out of the bowl and add it to the center of each mushroom.
Add the mushrooms to a small cast iron pan, or a baking dish, that's been lightly brushed with olive oil.
1 teaspoon olive oil
Once the mushrooms have all been stuffed, put them into the oven for 15 minutes.
Turn off the heat and remove the cast iron pan from the oven.
Cut slices of butter and add to the pan around the mushrooms. Put back into the oven to let the butter melt for another 3-4 minutes.
2 tablespoons butter
Serve any way you wish either as an appetizer or side dish. Enjoy!
