Ingredients
This casserole comes together with a mix of fresh vegetables, rice, and a savory blend of seasonings. Here’s what you’ll need:
For the Casserole:
- 1 lb ground beef (or ground turkey, chicken, or beef)
- 1 cup uncooked white or brown rice (brown rice adds more fiber and nutrients)
- 2 bell peppers, diced (red, green, or yellow)
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1 can (14.5 oz) diced tomatoes, drained
- 1 can (8 oz) tomato sauce

- 1 teaspoon dried oregano

Ingredient Highlights
- Ground Meat: Ground beef is the most traditional choice for stuffed peppers, but you can easily substitute it with turkey, chicken, or even beef to suit your preferences.
- Rice: Rice is an essential component of stuffed peppers and makes the dish filling and satisfying. Both white and brown rice work well, but brown rice adds more fiber and a nutty flavor.
- Bell Peppers: Bell peppers provide the fresh, slightly sweet taste that balances the richness of the meat and cheese. You can use any color, but red, yellow, and orange peppers tend to be the sweetest.
- Tomato Sauce & Diced Tomatoes: These ingredients form the base of the casserole’s sauce, giving it a rich, savory flavor and moisture to cook the rice.
- Cheese: Shredded cheese adds creaminess and helps bind the casserole together. Cheddar and mozzarella are popular choices, but you can mix it up with your favorite cheese.
- Seasonings: The combination of oregano, basil, and garlic adds depth and savory notes to the casserole. You can adjust the seasonings based on your preference.
Step-by-Step Instructions
First Step: Brown the Meat
- Heat the Skillet: In a large skillet, heat a tablespoon of oil over medium heat. Add the ground beef (or other ground meat of choice) and cook, breaking it up with a spoon or spatula as it cooks. Cook until browned and no longer pink in the middle, about 5-7 minutes.
- Season the Meat: While the meat is cooking, add the chopped onion and minced garlic. Sauté for an additional 2-3 minutes until the onion softens and becomes translucent.
- Drain the Fat: If there is excess fat in the pan, drain it off. This will help keep the casserole from becoming too greasy.
Second Step: Add the Vegetables
- Add the Bell Peppers: Stir in the diced bell peppers and cook for 2-3 minutes until they start to soften. The peppers should still retain some texture to add crunch to the casserole.
- Add the Tomatoes: Stir in the can of diced tomatoes (drained) and tomato sauce. Let the mixture simmer for a few minutes to allow the flavors to meld.
Third Step: Cook the Rice
- Add the Rice: Stir in the uncooked rice, beef or vegetable broth, and all the seasonings (oregano, basil, salt, pepper, and red pepper flakes, if using). Bring the mixture to a gentle boil.
- Simmer: Once it begins to boil, lower the heat, cover the skillet, and let the mixture simmer for 15-20 minutes until the rice is cooked through and most of the liquid has been absorbed. If you’re using brown rice, you may need to simmer it for a bit longer, about 30-40 minutes, depending on the type of rice.
Fourth Step: Assemble the Casserole
- Preheat the Oven: While the rice is cooking, preheat your oven to 375°F (190°C).
- Transfer to a Baking Dish: Once the rice is cooked, transfer the mixture to a greased 9×13-inch casserole dish. Spread it evenly in the dish.
- Top with Cheese: Sprinkle the shredded cheese over the top of the casserole. Feel free to use a combination of mozzarella and cheddar for a melty and flavorful topping.
Fifth Step: Bake and Serve
- Bake the Casserole: Place the casserole in the preheated oven and bake for 20 minutes, or until the cheese is melted and bubbly. If you like a crispy cheese top, you can broil the casserole for an additional 1-2 minutes at the end of the baking time.
- Garnish and Serve: Once the casserole is out of the oven, sprinkle some fresh parsley on top for a pop of color and added flavor. Slice into squares and serve warm.

How to Serve Stuffed Pepper Casserole

Additional Tips for Making Stuffed Pepper Casserole
To ensure that your casserole turns out perfectly every time, here are some tips and tricks:
- Brown Rice: If you’re using brown rice, it will take longer to cook. You can either pre-cook the rice and add it to the casserole or allow it more time to simmer.
- Vegetarian Option: To make this casserole vegetarian, simply omit the meat and use a plant-based protein (like lentils or beans) instead. You can also add extra vegetables like zucchini or mushrooms for a heartier option.
- Cheese Variations: Experiment with different cheeses to find your perfect flavor. Pepper jack cheese adds a nice kick, while a blend of mozzarella and Parmesan offers a rich, cheesy topping.
- Make It Spicy: Add some chopped jalapeños or use a spicy salsa in place of the tomato sauce to turn up the heat.
