Ingredient Notes
This stuffed pepper casserole uses familiar ingredients that work together to create a hearty, flavorful meal. Here are a few important details to help you get the best results.
Ground Beef or Ground Turkey
The recipe calls for 1 pound of ground beef or ground turkey. Ground beef provides a rich, savory flavor, while turkey is a convenient alternative if you prefer a different protein. Either choice works with the tomatoes, peppers, and Italian seasoning.
Bell Peppers
You’ll need 2 to 3 bell peppers, chopped into pieces. Any color works, so feel free to combine red, green, yellow, or orange peppers. Green bell peppers have a slightly more pronounced flavor, while red, yellow, and orange varieties tend to taste sweeter.
Chopping the peppers into similar-sized pieces helps them soften evenly during cooking.
Uncooked White Rice
White rice is the recommended choice for this recipe. The uncooked rice absorbs the seasoned broth and tomato mixture directly in the pot, bringing everything together without a separate rice-cooking step.
Use regular uncooked white rice rather than instant rice. Different rice varieties can require different amounts of liquid and cooking time, so changing the rice may require adjusting the recipe.
Diced Tomatoes and Tomato Paste
Canned diced tomatoes add moisture, acidity, and tomato flavor to the casserole. The recipe also includes 2 tablespoons of optional tomato paste, which gives the mixture a deeper, more concentrated tomato taste.
If you prefer a lighter tomato flavor, you can leave out the optional tomato paste.
Broth and Italian Seasoning
Chicken or beef broth provides the cooking liquid for the rice while adding savory flavor. Italian seasoning brings together herbs that complement the peppers, tomatoes, and ground meat.
Cheese Topping
Cheddar and mozzarella are both good options for finishing this casserole. Cheddar adds a sharper flavor, while mozzarella creates a mild, stretchy topping. Use whichever you prefer, or combine them for a delicious cheesy finish.
Step-by-Step Instructions
This Stuffed Pepper Casserole comes together on the stovetop, so there’s no need to preheat the oven or prepare a separate baking dish. Use a pot with a well-fitting lid, and have your ingredients ready before starting.
Preparation
- Heat a splash of oil in a pot over medium heat. Add the ground beef or ground turkey and cook until browned, breaking the meat into smaller pieces as it cooks. Season with salt and pepper. Browning the meat first develops savory flavor and creates a flavorful base for the remaining ingredients.
- Add the chopped onion and bell peppers to the browned meat. Cook for approximately 5 to 7 minutes, stirring occasionally, until the vegetables begin to soften. This step helps the peppers lose some of their raw firmness while allowing their natural flavor to blend with the meat.
- Stir in the minced garlic and Italian seasoning. Cook for approximately 30 seconds, stirring gently. This short cooking time allows the garlic and dried herbs to become fragrant without burning.
- Add the uncooked rice, diced tomatoes, optional tomato paste, and broth. Stir everything thoroughly so the rice is evenly distributed throughout the mixture. Bring the contents of the pot to a gentle simmer. The liquid will cook the rice while the tomatoes and seasonings flavor the entire casserole.
- Cover the pot with a lid and reduce the heat to low. Cook for approximately 18 to 22 minutes, or until the rice is tender. Stir once halfway through cooking to help prevent sticking and encourage even cooking. Keep the lid on during the remaining cooking time so the rice can absorb the liquid properly.
- Turn off the heat and sprinkle your preferred cheese over the top. Cover the pot again and allow it to rest for 3 to 5 minutes, until the cheese melts. This final resting period also gives the rice mixture a chance to settle before serving.
Tips & Tricks
- Cut the peppers evenly: Try to keep the chopped bell peppers approximately the same size. Uneven pieces may soften at different rates, leaving some overly soft while others remain too firm.
- Use the right rice: Regular uncooked white rice is the easiest option for this recipe. Instant rice and brown rice behave differently and may not cook properly using the same liquid and timing.
- Maintain a gentle simmer: Once the rice has been added, keep the heat low. Cooking too aggressively can cause the liquid to evaporate before the rice becomes tender.
- Check the rice before finishing: Make sure the rice is fully tender before adding the cheese. If it needs more cooking, check that enough moisture remains in the pot and continue gently until the rice is done.
- Let the cheese melt with the heat off: Covering the warm casserole after adding cheese allows it to melt without prolonged cooking, helping prevent the bottom from becoming dry.
Variations & Substitutions
One of the best things about this easy stuffed pepper casserole is how adaptable it can be. A few simple changes let you adjust the recipe to your preferences.
- Use ground turkey: Substitute ground turkey for ground beef using the option already included in the recipe card. The seasoning and tomato mixture work well with either protein.
- Mix bell pepper colors: Combine green peppers with sweeter red, yellow, or orange peppers for a colorful dish with a balance of flavors.
- Choose a different cheese: Try cheddar for a more pronounced cheesy flavor or mozzarella for a milder, softer topping.
- Change the broth: Use either chicken broth or beef broth, depending on your preference and what you have available.
- Consider a lower-carb variation: The recipe notes mention cauliflower rice as an alternative. However, cauliflower rice releases moisture and cooks differently from uncooked white rice, so it is not a direct one-for-one substitution using the same liquid and cooking time.
Serving Suggestions
This Stuffed Pepper Casserole is filling enough to serve as a complete main course. With meat, rice, vegetables, and melted cheese in every spoonful, it offers plenty of variety without requiring several side dishes.
For a lighter meal, serve it alongside a simple green salad with a tangy vinaigrette. The fresh vegetables and acidity provide a pleasant contrast to the warm, savory casserole.
Steamed green beans or roasted vegetables also make easy accompaniments. If you’re feeding a larger group, a small serving of crusty bread can help round out dinner.
For the best presentation, spoon the casserole into individual bowls or onto plates while it’s still warm, allowing the melted cheese to remain soft and creamy.
Storage & Reheating
Refrigerating Leftovers
Transfer leftover casserole into shallow, airtight containers and refrigerate promptly. Because this dish contains cooked rice and meat, proper cooling and refrigeration are especially important.
The rice may absorb more moisture as the casserole sits in the refrigerator, so the texture will likely become thicker than when freshly cooked.
Reheating
Reheat individual portions in the microwave, stirring as needed to distribute the heat evenly. Alternatively, warm the casserole gently in a covered pot over low heat.
If the mixture seems dry, add a small splash of broth while reheating. Heat thoroughly before serving.
Making Ahead
This casserole can work well for meal preparation. Cook it according to the recipe, cool it promptly, and store it properly in the refrigerator. Reheat individual portions when needed.
Keep in mind that the rice will continue absorbing moisture during storage, so reheated portions may be softer than the freshly prepared casserole.

Frequently Asked Questions
Can I make Stuffed Pepper Casserole with ground turkey?
Yes. Ground turkey is included as an alternative to ground beef in the original recipe. Brown it thoroughly and follow the same preparation steps.
Do I need to cook the rice before adding it?
No. The recipe uses uncooked white rice, which cooks directly in the tomato and broth mixture. Make sure the pot is covered and the heat stays low while the rice becomes tender.
Can I use brown rice instead of white rice?
Brown rice generally requires a longer cooking time and may need additional liquid. The recipe’s original cooking method is designed for white rice, so brown rice would require adjustments.
Can I make this casserole without tomato paste?
Yes. Tomato paste is optional in the recipe. Leaving it out will produce a slightly less concentrated tomato flavor, but the diced tomatoes will still contribute plenty of flavor.
Does Stuffed Pepper Casserole need to go in the oven?
No. This particular recipe is prepared entirely on the stovetop. The meat, vegetables, and rice cook together in a covered pot, and the cheese melts using the remaining heat after cooking.
