Cooking Time: 30 min
What You'll Need:
1 pound large fresh mushrooms
3 tablespoons butter
1/2 cup finely chopped onion
1 packet onion soup mix
1 tablespoon water
1/4 cup plain bread crumbs
1/8 teaspoon black pepper
3 slices Swiss cheese, each slice cut into 4 squares
What To Do:
1. Preheat oven to 375 degrees F. Gently clean mushrooms by wiping them with damp paper towels. Remove stems from 12 mushrooms; set aside caps. Finely chop mushroom stems and remaining whole mushrooms.
2. In a large skillet over medium heat, melt butter; cook onion 3 minutes, or just until soft. Stir in chopped mushrooms, onion soup mix, and water and cook 4 to 5 minutes, or until tender. Remove from heat and add bread crumbs and black pepper; mix well.
3. Using a teaspoon, stuff mushroom caps with stuffing mixture. Place on ungreased baking sheet.
4. Bake 12 minutes. Remove from oven, top each with a piece of cheese, and return to oven 5 minutes, or until cheese is melted and mushrooms are heated through. Serve immediately.
