How to Make Stuffed Pepper Casserole Recipe
Step 1: Preheat and Sauté
Start by preheating your oven to 375 degrees F, which gets everything ready for the baking stage. Next, heat the olive oil in a 12-inch ovenproof skillet or Dutch oven over medium heat. Add the diced onion, minced garlic, bell peppers, and ground beef. Sauté this delicious mix for about 10 minutes until the beef is browned and the vegetables are softened. This step locks in those bold and fresh flavors that set the foundation for the whole dish.
Step 2: Add Remaining Ingredients
Once your base is fragrant and browned, pour in the tomato sauce, petite diced tomatoes, salt, pepper, dried oregano, basil, rice, and beef broth. Stir everything together until fully combined. You’ll notice the rice and broth start soaking up the delicious juices right away, promising a casserole that’s bursting with flavor and great texture from every spoonful.
Step 3: Bake
Cover your skillet with aluminum foil to keep the moisture in. If you don’t have an ovenproof skillet, transfer the mixture to a casserole dish and cover that tightly instead. Pop it into the oven and bake at 375 degrees F for 20 minutes. This slow bake lets the rice cook perfectly while the flavors deepen and meld.
Step 4: Add Cheese
After the initial bake, pull the casserole out and remove the cover. Sprinkle the mozzarella cheese evenly on top, then return it to the oven for another 10 minutes. This final bake melts the cheese into a bubbly, golden crust that adds a delightful texture and richness to the dish.
Step 5: Serve and Enjoy
At this point, your stuffed pepper casserole is just about ready. The rice will have absorbed all the flavorful liquid, and the cheese will be perfectly melted and slightly browned. Serve hot and watch as everyone digs into this comforting, colorful casserole with smiles all around. It’s an effortless way to enjoy all the joy of stuffed peppers in one pan!
How to Serve Stuffed Pepper Casserole Recipe

Garnishes
Fresh herbs like chopped parsley or basil sprinkled on top bring a burst of freshness that brightens the dish right before serving. You can also add a dollop of sour cream or a drizzle of hot sauce if you prefer a little tang or heat. These simple touches elevate the presentation and taste, making it feel extra special.
Side Dishes
This casserole is quite filling on its own, but pairing it with a crisp green salad or steamed vegetables balances the meal with some refreshing crunch and color. Garlic bread or crusty rolls are also a fantastic companion to soak up any delicious leftover sauce.
Creative Ways to Present
If you’re hosting guests or want to jazz things up, try serving individual portions in small ramekins with melted cheese on top. Add a sprinkle of paprika or some finely diced red pepper for a pop of color. This makes the dish look trendy and adds a touch of fun to your table presentation.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer any leftovers to an airtight container and store in the refrigerator for up to 3 days. The flavors often deepen overnight, making it even better the next day. Just make sure to store it properly to maintain freshness and texture.
Freezing
This Stuffed Pepper Casserole Recipe freezes beautifully. Portion it out into freezer-safe containers and freeze for up to 2 months. When you’re ready to enjoy it, thaw overnight in the fridge for best results. This makes it a perfect meal prep option or a lifesaver for busy weeknights.
Reheating
Reheat leftovers gently in the oven at 350 degrees F, covered with foil, until warmed through—usually about 15-20 minutes. Alternatively, microwave individual servings for 2-3 minutes, stirring halfway through to ensure even heat. Adding a sprinkle of extra cheese on top before reheating is a tasty bonus!
FAQs
Can I use different types of rice for this recipe?
Absolutely! While white minute rice works perfectly because it cooks quickly and absorbs flavors well, you can use long-grain rice or even brown rice. Just be mindful that cooking times might need adjusting if you swap in a rice that takes longer to cook.
Is it possible to make this recipe vegetarian?
Yes, you can replace the ground beef with plant-based meat alternatives, crumbled tofu, or extra vegetables like mushrooms and zucchini. Just make sure to use vegetable broth instead of beef broth and adjust seasoning to keep that wonderful savory balance.
Can this dish be made gluten-free?
Definitely! This recipe is naturally gluten-free as long as you use gluten-free beef broth and check that your canned tomatoes and tomato sauce have no added gluten ingredients. It’s a delicious gluten-free option that doesn’t compromise on flavor.
How spicy is the Stuffed Pepper Casserole Recipe?
This version is mild and family-friendly, focusing on savory and herbaceous flavors. However, you can easily spice it up by adding red pepper flakes, chopped jalapeños, or your favorite hot sauce either during cooking or as a garnish.
Can I make this recipe ahead and bake it later?
Yes! After sautéing and combining all ingredients (before adding cheese), cover and refrigerate the casserole for up to 24 hours. When ready, bake as directed, adding cheese toward the end. It’s a great way to save time on busy days while still enjoying fresh-baked goodness.

- 2 cups white minute rice, uncooked

Dairy

Instructions
- Preheat and Sauté: Preheat your oven to 375°F (190°C). In a 12-inch ovenproof skillet or Dutch oven, heat 1 tablespoon of olive oil over medium heat. Add the diced onion, minced garlic, and diced bell peppers along with 1 lb of lean ground beef. Sauté everything together for about 10 minutes, stirring occasionally until the beef is browned and the peppers and onions have softened.

Stir thoroughly to combine all ingredients evenly in the skillet or Dutch oven.
- Bake: Cover the skillet tightly with aluminum foil. If your skillet isn’t ovenproof, transfer the mixture to a casserole dish and cover with a lid or foil. Bake in the preheated oven at 375°F for 20 minutes, allowing the rice to absorb the liquid and flavors.
- Add Cheese: Remove the foil or cover carefully. Sprinkle ½ cup of part-skim mozzarella cheese evenly over the casserole. Return the dish to the oven and bake uncovered for an additional 10 minutes or until the cheese has melted completely and starts to turn golden brown.
- Serve: Once the cheese is melted and bubbly, the casserole is ready. The rice should have absorbed most of the liquid, making a cohesive and delicious meal. Serve hot and enjoy your flavorful stuffed pepper casserole!
Notes
- Use any color combination of bell peppers for a vibrant and tasty dish.
- If you prefer, substitute ground turkey or chicken for a leaner protein option.
- Minute rice cooks quickly and absorbs the broth well, but regular white rice can be used if cooked beforehand.
- Covering during baking ensures the rice cooks through and stays moist.
- Feel free to add extra vegetables like mushrooms or zucchini to customize the casserole.
- For a spicier kick, add crushed red pepper flakes or hot sauce to the tomato mixture.
