Recipe Ingredients

  • 4 slices bacon
  • 2 (12 ounce) packages fresh white mushrooms
  • 3 tablespoons butter, melted
  • 6 pitted black olives, finely chopped
  • ¼ cup finely chopped green onion
  • 1 teaspoon oil-packed minced garlic
  • ½ teaspoon salt
  • ¼ teaspoon ground black pepper
  • 1 pinch cayenne pepper
  • 1 tablespoon all-purpose flour
  • ¼ cup milk
  • 4 slices Swiss-flavored American cheese, chopped
  • 3 tablespoons grated Parmesan cheese

Cooking Directions

  1. 1 Preheat oven to 375 degrees F (190 degrees C).
  2. 2 Place bacon in a large skillet and cook over medium-high heat, turning occasionally, until evenly browned, about 10 minutes. Transfer bacon slices to paper towels, reserving bacon drippings in the skillet. Crumble bacon when cooled.
  3. 3 Remove stems from mushrooms and set stems aside. Place mushrooms, hollow sides up, on a baking sheet; brush the insides with melted butter.
  4. 4 Chop mushroom stems; cook and stir chopped stems, black olives, green onion, and crumbled bacon in the bacon drippings over medium heat until mushroom stems release their liquid, about 5 minutes. Add garlic, salt, black pepper, and cayenne pepper; stir to coat.
  5. 5 Tilt the skillet slightly; move vegetable-bacon mixture to one side, allowing the bacon drippings to pool to the other side. Whisk flour into bacon drippings until smooth and paste-like; slowly stir in milk until gravy is smooth. Mix vegetable-bacon mixture into the gravy. Add American cheese and Parmesan cheese; cook and stir until cheeses melt, about 5 minutes. Spoon filling into mushroom caps.
  6. 6 Bake in the preheated oven until mushrooms are tender and filling is lightly browned, about 20 minutes. Remove mushrooms from baking sheet and cool on platter for 2 minutes before serving.

Chef's Notes

Substitute bacon with breakfast sausage. Add ½ cup frozen drained spinach, squeezed dry, if desired. Add 2 tablespoons bread crumbs to cheese mixture for a heartier filling.


  1. Very tasty. My guests loved this.
  2. I made this recipe for Super Bowl Sunday. They are the best stuffed mushrooms ever.
  3. Just made this recipe a couple of days ago for a party. They are to die for! I used more 2 more slices of bacon and twice the garlic that what the recipe says. I also hollowed out the mushrooms a bit more to make room for more stuffing. People could not stop eating them. - Read more ...
