Preheat Oven: Preheat your oven to 375°F (190°C).
Prepare Bell Peppers: Slice the tops off the bell peppers and remove seeds and membranes. Blanch them in boiling water for 3–4 minutes, then drain and set aside.
Cook Beef Filling:
Heat olive oil in a skillet over medium heat.
Add onions and sauté for 2–3 minutes until softened.
Add ground beef, garlic, salt, pepper, paprika, and Italian seasoning. Cook until beef is browned and crumbly.
Add Rice and Sauce: Stir in cooked rice and half of the tomato sauce. Mix until well combined. Simmer for 2–3 minutes, then remove from heat.
Stuff Peppers: Spoon the beef mixture into each bell pepper, packing firmly. Place them upright in a baking dish.
Add Baking Sauce: In a bowl, mix remaining tomato sauce, beef broth, and Worcestershire sauce. Pour this around and lightly over the peppers.
Bake: Cover with foil and bake for 35 minutes. Remove foil, sprinkle cheese on top, and bake uncovered for another 10–15 minutes until cheese is melted and golden.
Garnish and Serve: Sprinkle fresh herbs on top before serving.
