Ingredients
Bell Peppers
- 5 medium-sized bell peppers (preferably red, yellow, or orange), 3 cut in half lengthwise, 2 sliced into thin strips then cut in half
Beef and Vegetables
- 1 pound lean ground beef (90-93% lean)
- 16 ounces white button mushrooms, sliced
- 1 large onion, chopped
- 3 cloves garlic, minced
- 1/2 teaspoon garlic powder
- 2 tablespoons dried Italian seasoning
- 1/3 cup fresh parsley, chopped, plus more for garnish
Liquids and Seasonings
- 2 tablespoons olive oil
- 1/2 cup beef stock
- 3 tablespoons Worcestershire sauce
- Salt and pepper to taste (about 1 teaspoon each during cooking, plus more as needed)
Cheese
- 6 slices provolone cheese
Instructions
- Preheat and Prep Peppers: Preheat your oven to 400°F. Cut three bell peppers in half lengthwise and remove seeds and membranes. Arrange them cut side up in a baking dish, then bake for 15 minutes. Remove and set aside. Lower oven temperature to 375°F.
- Sauté Mushrooms: Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add sliced mushrooms, season with salt and pepper, and cook for 6-8 minutes until they release liquid and begin to brown. Remove mushrooms and set aside.
- Cook Onions and Seasonings: Reduce heat to medium, add remaining 1 tablespoon olive oil to the skillet, then cook chopped onion until softened, about 5-6 minutes. Stir in garlic powder, Italian seasoning, and minced garlic; cook an additional 1 minute until fragrant.
- Cook Ground Beef and Peppers: Turn heat back to medium-high. Add ground beef and sliced bell peppers to the pan, along with 1 teaspoon salt and pepper. Saute and break up the meat, cooking until beef is browned and cooked through, about 6-8 minutes. Stir occasionally for even cooking.
- Add Mushrooms and Liquids: Return the cooked mushrooms to the skillet. Pour in beef stock, Worcestershire sauce, and add chopped parsley. Cook mixture on medium heat for 5 minutes to meld flavors. Taste and adjust salt and pepper if needed. Remove from heat and let sit for 3 minutes.
- Stuff Peppers: Spoon the beef mixture into each pre-roasted bell pepper half, pressing down gently to pack the filling evenly.
- Bake Stuffed Peppers: Cover the baking dish with foil and bake in the oven at 375°F for 20 minutes, until peppers are tender.
- Add Cheese and Finish Baking: Remove foil and top each stuffed pepper with a slice of provolone cheese. Return to oven and bake for 5 more minutes until cheese is melted and bubbly. Garnish with additional chopped parsley and serve warm.
Notes
- You can substitute ground beef with ground turkey or chicken for a leaner option.
- For a cheesier version, feel free to add more slices of provolone or sprinkle mozzarella on top.
- Use bell peppers of different colors for a vibrant presentation.
- Store leftovers in an airtight container and refrigerate for up to 3 days; reheat in the oven to maintain texture.
