How to Make Stuffed Pepper Casserole Recipe
Step 1: Preheat and Sauté
Start by preheating your oven to 375 degrees F, so it’s ready by the time your skillet is all set. In a 12-inch ovenproof skillet or Dutch oven, warm the olive oil over medium heat. Toss in the diced onions, minced garlic, colorful diced bell peppers, and lean ground beef. Sauté this vibrant mixture for about 10 minutes until the beef turns beautifully brown and the veggies have softened into tender sweetness. This step builds the foundational flavors that make this casserole so irresistible.
Step 2: Add Remaining Ingredients
Next, stir in the tomato sauce and petite diced tomatoes along with the salt, pepper, dried basil, oregano, and parsley. Pour in the uncooked white minute rice and beef broth, then combine everything gently but thoroughly. The uncooked rice will soak up all the delicious tomato juices and broth, creating a perfectly tender texture as it bakes.
Step 3: Bake Covered
Cover your skillet tightly with aluminum foil to trap steam and encourage the rice to absorb all the rich flavors evenly. If you don’t have an ovenproof skillet, simply transfer the mixture to a casserole dish, cover with a lid or foil, and pop it into the preheated oven. Bake at 375 degrees F for 20 minutes, letting the casserole bubble and the rice cook through.
Step 4: Add Cheese and Finish Baking
After those first 20 minutes, carefully remove the foil and sprinkle the mozzarella cheese evenly over the top. Return the dish to the oven uncovered and bake for an additional 10 minutes. You’ll know it’s ready when the cheese is melted, delightfully bubbly, and just starting to brown, creating a fantastic cheesy crust that’s impossible to resist.
Step 5: Serve and Enjoy
By the time it’s done, the rice will have fully absorbed all the flavorful liquids, and your stuffed pepper casserole will be bubbling with savory goodness. Serve it up hot and watch as everyone dives into this cozy dish that delivers all the charm of classic stuffed peppers in a single, satisfying casserole form.
How to Serve Stuffed Pepper Casserole Recipe
Garnishes
To elevate the presentation and flavor, sprinkle freshly chopped parsley or basil leaves over the top just before serving. A light drizzle of extra virgin olive oil or a sprinkle of crushed red pepper flakes can add an extra special touch that wakes up the palate. These simple garnishes add freshness and a pop of color to make every bite delightful.
Side Dishes
While this Stuffed Pepper Casserole Recipe makes a fulfilling meal on its own, pairing it with a fresh green side salad or a crisp cucumber and tomato salad can add a refreshing contrast. Garlic bread or warm, crusty rolls are also fantastic companions that soak up any remaining sauce and complete the meal beautifully.
Creative Ways to Present
For a fun twist, serve this casserole in individual ramekins or small ovenproof dishes, letting everyone enjoy their personal portion with a bubbly cheesy top. Another idea is to spoon it over a bed of greens for a warm salad-style meal, or even use it as a hearty filling for stuffed pita pockets for an inventive lunch option.
Make Ahead and Storage
Storing Leftovers
You can store leftover Stuffed Pepper Casserole Recipe in an airtight container in the refrigerator for 3-4 days. The flavors meld beautifully overnight, making your next-day meal just as delicious, if not better. Just be sure to cool it completely before refrigerating to maintain the best texture and freshness.
Freezing
This casserole freezes wonderfully. Portion it into freezer-safe containers, seal tightly, and freeze for up to 3 months. When properly thawed in the fridge overnight before reheating, it retains its flavor and texture well, making it a great option for meal prepping or busy nights.
Reheating
To reheat, microwave individual portions or warm the entire casserole covered with foil in a 350 degrees F oven until heated through, about 20 minutes. If frozen, thaw first for even reheating. Adding a splash of broth or water before reheating helps maintain the casserole’s moisture and keeps every bite tender.
FAQs
Can I use different types of rice for this casserole?
Yes, but keep in mind cooking times and liquid ratios may vary. Minute rice is ideal because it cooks quickly and absorbs flavors well. If using regular long-grain rice, you might need to adjust the broth amount and baking time accordingly.
Is it possible to make this casserole vegetarian?
Absolutely! Simply swap the ground beef for a plant-based meat substitute or add extra beans like black beans or lentils to maintain a hearty texture and protein content without meat.
Can I prepare this dish without an ovenproof skillet?
Definitely. You can sauté the beef and vegetables in a regular skillet, then transfer the mixture to a casserole dish for baking. Just be sure the dish is covered well to keep moisture in during baking.
What other cheeses can I use instead of mozzarella?
Cheddar, Monterey Jack, or a blend of Italian cheeses work well and add your favorite cheesy twist. Just choose a cheese that melts nicely and complements the tomato and pepper flavors.
How spicy is this casserole? Can I add heat?
This recipe is mild by default, highlighting the natural sweetness of the peppers and herbs. However, feel free to add crushed red pepper flakes, diced jalapeños, or a dash of hot sauce if you crave some heat.

If you’re craving a comforting, flavorful dish that brings all the joy of stuffed peppers with less effort and mess, this Stuffed Pepper Casserole Recipe is just what you need.

Ingredients
Produce
- 1/2 cup onion, diced (1 small onion)

- ½ teaspoon salt
- 1 teaspoon pepper
- 1 teaspoon dried basil
- 1 teaspoon dried oregano
- 1 teaspoon dried parsley
- 2 cups white minute rice, uncooked
Liquids
- 2 cups beef broth, low or no salt
Instructions
- Preheat the oven and sauté ingredients: Preheat your oven to 375 degrees F. In a 12-inch ovenproof skillet or Dutch oven, heat olive oil over medium heat. Add the minced garlic, diced onion, diced bell peppers, and ground beef. Sauté this mixture for about 10 minutes, stirring occasionally, until the beef is fully browned and the vegetables are softened.
- Add remaining ingredients: To the skillet, add the tomato sauce, petite diced tomatoes (with their juice), salt, pepper, dried oregano, dried basil, dried parsley, uncooked white minute rice, and low-sodium beef broth. Stir everything together until well combined.
- Bake covered: Cover the skillet tightly with aluminum foil. If your skillet is not ovenproof, transfer the mixture to a casserole dish and cover with a lid or foil. Place it into the preheated oven and bake for 20 minutes. This baking step allows the rice to cook and absorb the liquids.
- Add cheese and finish baking: After 20 minutes, remove the foil or cover. Sprinkle the part-skim mozzarella cheese evenly on top. Return the dish to the oven and bake uncovered for an additional 10 minutes, or until the cheese has melted and starts to brown lightly.
- Serve and enjoy: At this point, the rice should have absorbed the liquid completely, and the casserole is hot and ready to be served. Spoon portions onto plates and enjoy this hearty stuffed pepper casserole.
Notes
- For a vegetarian version, substitute ground beef with a plant-based protein or additional vegetables and use vegetable broth instead of beef broth.
- Using minute rice helps reduce the overall cooking time, but you can substitute regular rice; just adjust the cooking time accordingly and add more broth if needed.
- Feel free to use any color combination of bell peppers to enhance the flavor and appearance.
- If you prefer a sharper cheese, try part-skim mozzarella mixed with a bit of Parmesan on top.
- Make sure to cover the dish tightly during the initial baking to allow the rice to steam properly.
