Ingredients
  

  • Bell peppers: 4 large peppers, any color. Green is classic and slightly bitter; red and yellow are sweeter.
  • Beef: 1 pound thinly sliced steak (ribeye is best) or shaved beef. Flank, sirloin, or top round also work if sliced thin.
  • Onion: 1 large yellow or white onion, thinly sliced.
  • Mushrooms (optional): 8 ounces cremini or button mushrooms, sliced.
  • Cheese: 8–10 slices provolone or American, or about 1 cup shredded provolone or mozzarella. Cheez Whiz is a classic option too.
  • Garlic: 2 cloves, minced.
  • Worcestershire sauce: 1 tablespoon for depth and umami.
  • Beef stock (optional): 2–3 tablespoons to moisten the filling if needed.
  • Butter or oil: 1–2 tablespoons for sautéing.
  • Salt and pepper: To taste.
  • Optional add-ins: Hot cherry peppers, banana peppers, or a pinch of red pepper flakes for heat.

Method
 

  1. Prep the peppers: Preheat oven to 400°F (205°C). Slice the tops off the bell peppers and remove seeds and membranes. If they wobble, shave a thin slice from the bottoms to help them stand.
  2. Par-bake the shells: Place peppers in a baking dish, drizzle with a little oil, and sprinkle with salt. Bake for 12–15 minutes until slightly softened but still holding shape. This helps prevent crunchy or undercooked peppers later.
  3. Sauté the onions and mushrooms: In a large skillet over medium-high heat, melt butter or warm oil. Add onions and a pinch of salt. Cook 5–7 minutes, stirring, until golden and soft. Add mushrooms and cook another 4–5 minutes until browned. Stir in garlic for 30 seconds.
  4. Cook the beef: Push veggies to the side. Add sliced beef in an even layer. Season with salt and pepper. Cook 2–4 minutes, stirring just until barely pink. Don’t overcook or it will turn tough.
  5. Flavor the filling: Stir in Worcestershire sauce and a splash of beef stock if the mixture seems dry. Taste and adjust seasoning. If you like heat, add chopped hot peppers or red pepper flakes now.
  6. Layer with cheese: Turn off the heat. Lay a few slices of cheese over the hot beef and vegetables. Let it melt slightly, then toss gently to coat. This helps the filling hold together.
  7. Stuff the peppers: Spoon the cheesy beef mixture into the par-baked pepper shells, packing it in. Top each with another slice of cheese for that classic cheesesteak melt.
  8. Bake to finish: Return the stuffed peppers to the 400°F (205°C) oven. Bake 10–12 minutes, until the cheese is melted and the peppers are tender but not collapsing.
  9. Optional broil: For browned, bubbly tops, broil for 1–2 minutes. Watch closely to avoid burning.
  10. Rest and serve: Let them rest 5 minutes so the juices settle. Garnish with chopped parsley or a few pickled hot peppers if you like. Serve warm.
