For easy clean up, line a baking dish with foil. Preheat oven to 400 degrees.
Select larger white mushrooms, clean, and remove stems. For 2 servings, I usually use 8 to 10 mushrooms, depending on their size.
Place mushrooms-- TOP side down to expose the cavity,for easy filling.
In a small bowl mix together-
Cream Cheese ( you judge the amount that you will need, by number of mushrooms to fill )
Crumbled, Cooked Bacon or Bacon Bits. ( 1 piece for 8 mushrooms is usually enough )
Fill the mushroom cavities with this mixture.
Top with a little mound a grated cheese - Cheddar or Jack work well.
Slice half a stick of real butter and lay in the bottom of the pan, around the mushrooms.
Top butter with just a LITTLE-- TINY pinch of garlic powder,salt or fresh ( whatever you have)
Bake in the oven for 15 to 20 minutes. Remove from oven.
Place a teaspoon or two of the melted butter on a small plate or bowl.
Set your mushrooms on top of the butter. And Enjoy.
Quick method. Casserole Style.
Grease your baking dish with spray, oil or butter.
Cut up your mushrooms and place in baking dish.
Add cream cheese,bacon, butter and garlic.
Cook in microwave or oven until cream cheese and butter are melted.
Stir it all together, Top with Cheese and bake in oven 15 minutes.
I make this quick style totally in the microwave, only reduce your cooking time. It just takes minutes. Give it a final stir. Add the grated cheese and cook another minute, until melted.
