Introduction
Stuffed Pepper Casserole is a comforting, hearty meal that brings all the classic flavors of traditional stuffed peppers into a simple, easy-to-make dish. Instead of carefully filling individual peppers, everything is layered together in one casserole, making the preparation quicker and perfect for busy weeknights. The combination of seasoned ground meat, tender rice, sweet bell peppers, and a rich tomato sauce creates a satisfying meal that feels both wholesome and flavorful.
I first tried making stuffed pepper casserole when I wanted the taste of stuffed peppers without the extra preparation time. The result was even better than expected. The peppers soften beautifully as they bake, and the flavors blend together perfectly with the rice and savory meat. It quickly became one of those recipes I return to when I want something warm, filling, and reliable.
This casserole is also incredibly family-friendly. It is simple, customizable, and reheats wonderfully, making it ideal for meal prep or leftovers the next day.

Onion

Garlic

Tomato Sauce

Diced Tomatoes

Beef Broth

Italian Seasoning

Shredded Cheese

Directions
Begin by preheating the oven to 375°F (190°C). Lightly grease a casserole dish to prevent sticking during baking.
In a large skillet over medium heat, cook the ground beef until it is browned and fully cooked. Break the meat into small pieces while cooking to ensure an even texture. Drain any excess fat if necessary.
Add the chopped onion and cook for about three minutes until it becomes soft and fragrant. Stir in the minced garlic and cook for another minute to release its aroma.
Next, add the chopped bell peppers to the skillet. Cook them for about four to five minutes until they begin to soften slightly but still maintain their shape.
Stir in the uncooked rice, tomato sauce, diced tomatoes, and beef broth. Mix everything thoroughly so the rice is evenly distributed throughout the mixture.
Season the mixture with Italian seasoning, paprika, salt, and black pepper. Allow the mixture to simmer for a few minutes so the flavors begin to combine.
Transfer the entire mixture into the prepared casserole dish and spread it evenly. Cover the dish with foil and place it in the oven.
Bake the casserole for about 35–40 minutes until the rice is tender and most of the liquid has been absorbed. Remove the foil, sprinkle shredded cheese over the top, and return the dish to the oven for another 10 minutes until the cheese is melted and slightly golden.
Allow the casserole to rest for a few minutes before serving so the flavors settle and the texture firms up slightly.

Storage/reheating
Stuffed Pepper Casserole stores very well, making it an excellent choice for leftovers or meal prep. Allow the casserole to cool completely before storing it.
Place leftovers in an airtight container and refrigerate for up to four days. When reheating, warm individual portions in the microwave for about two to three minutes, stirring halfway through to ensure even heating.
You can also reheat the casserole in the oven at 350°F (175°C) for about 15 minutes until heated through.

Variations and Customizations
Stuffed Pepper Casserole is incredibly flexible, which makes it a great recipe to adjust based on personal taste or dietary preferences. One simple variation is to swap the ground beef for ground turkey or ground chicken. These options create a lighter version of the dish while still maintaining plenty of flavor.
If you prefer a slightly healthier version, you can replace white rice with brown rice or quinoa. Brown rice adds extra fiber and a nuttier flavor, while quinoa increases the protein content and creates a slightly different texture.
Another variation is adding more vegetables. Mushrooms, zucchini, corn, or spinach can easily be mixed into the casserole. These additions increase both the nutritional value and the flavor complexity of the dish.
Spice lovers may want to add crushed red pepper flakes or a diced jalapeño for a bit of heat. This small change can give the casserole a pleasantly spicy twist without overpowering the other ingredients.
You can also experiment with different cheeses. While cheddar is commonly used, mozzarella, Monterey Jack, or even a blend of cheeses can add a different flavor and texture to the topping.
For a low-carb version, replace the rice with cauliflower rice. This option keeps the casserole light while still providing the structure and texture that rice normally contributes.
Finally, if you want to enhance the flavor even further, try topping the casserole with fresh herbs like chopped parsley or basil just before serving. The freshness brightens the dish and adds a beautiful finishing touch.
