Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Bell peppers form the backbone of this dish. When chopped and cooked, they become tender while still offering a mild sweetness that balances the savory components.

Ground beef provides richness and depth. It absorbs the seasonings beautifully and gives the casserole its hearty texture. Ground turkey can also be used for a lighter option.

Onion adds a subtle sweetness and aromatic base. As it cooks, it softens and blends seamlessly into the casserole.

Garlic enhances the overall flavor profile. Even a small amount brings warmth and complexity to the dish.

Cooked rice acts as the binding element. It absorbs the sauce and seasonings, ensuring every bite is balanced and satisfying.

Tomato sauce creates a rich, slightly tangy foundation. It ties the ingredients together and keeps the casserole moist.

Diced tomatoes add texture and freshness. They provide small bursts of acidity that brighten the dish.

Italian seasoning contributes a blend of herbs that complements the peppers and meat without overpowering them.

Paprika adds a gentle smokiness and depth of color.

Salt and black pepper are essential for seasoning and enhancing all the other ingredients.

Shredded cheese finishes the casserole with a creamy, melted topping. Cheddar or mozzarella both work exceptionally well.

Directions

Begin by preheating your oven to 190°C. Lightly grease a large baking dish and set it aside. In a large skillet over medium heat, cook the ground beef until browned, breaking it up as it cooks. Drain excess fat if necessary. Add the chopped onion and cook until softened, followed by the garlic, stirring until fragrant.

Stir in the chopped bell peppers and cook for a few minutes until they begin to soften. Add the cooked rice, tomato sauce, diced tomatoes, and all seasonings. Mix thoroughly so the ingredients are evenly combined. Allow the mixture to simmer for about five minutes, letting the flavors meld together.

Transfer the mixture into the prepared baking dish, spreading it evenly. Sprinkle the shredded cheese over the top. Cover with foil and bake for 25 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is melted and lightly golden. Allow the casserole to rest briefly before serving.

Variations and Customizations

This casserole is highly adaptable, making it easy to tailor to personal preferences or dietary requirements. For a lighter version, ground turkey or chicken can replace beef without sacrificing flavor. If you prefer a vegetarian option, omit the meat entirely and substitute it with lentils or black beans for added protein and texture.

Grain choices can also be adjusted. While white rice is traditional, brown rice adds a nutty flavor and extra fiber. Cauliflower rice works well for a low-carbohydrate version, though it should be added toward the end to avoid excess moisture.

Seasonings offer another opportunity for customization. Adding chili flakes or cayenne pepper introduces heat, while cumin brings a warm, earthy note. Different cheeses can be used for variety; a blend of mozzarella and cheddar creates a balanced melt, while pepper jack adds a subtle kick.

For added vegetables, consider incorporating zucchini, mushrooms, or spinach. These additions increase nutritional value and enhance texture without overpowering the classic stuffed pepper flavor.
