This Easy Stuffed Pepper Casserole is a tasty and filling dish that’s perfect for a cozy dinner. It combines colorful bell peppers, rice, and seasoned meat in a warm, cheesy mix!
What’s great about this casserole is how simple it is to make. Just toss everything together and let it bake. Honestly, I love how I can load up my plate and still have leftovers for lunch!
Key Ingredients & Substitutions
Ground Beef: This adds hearty flavor and protein. If you’re looking for a leaner option, try ground turkey or even a plant-based meat substitute for a vegetarian version.
Bell Peppers: Any color works here, but I love using a mix for a pop of color. If you’re out of fresh peppers, you can use frozen bell peppers instead, just thaw them first!
Rice: While white rice is standard, you can switch it up with brown rice for extra fiber. Quinoa is a great gluten-free option too!
Cheddar Cheese: Cheddar is delicious, but feel free to experiment with Monterey Jack, pepper Jack for a spicy kick, or even mozzarella for a different texture.
How Do I Ensure My Casserole Is Full of Flavor?
Getting the flavors right in the casserole is key. Start by seasoning your ground beef properly while it cooks. Don’t rush the sautéing process when cooking the onion and garlic; it really brings out their sweetness.
- Use medium heat to sauté onions and garlic until they become soft and aromatic.
- Add the bell peppers for a few minutes to develop their flavor before combining them with the meat.
- Don’t forget to taste and adjust the seasoning as you mix in the rice and sauces!

- 1 (14.5 oz) can diced tomatoes, undrained
- 1 cup cooked white rice

How Much Time Will You Need?
This casserole is quick and easy! You’ll need about 10 minutes for preparation and about 25 minutes for baking, plus a few minutes to let it cool. In total, expect to spend about 35-40 minutes from start to finish!
Step-by-Step Instructions:
1. Preheat the Oven:
First things first! Preheat your oven to 350°F (175°C) so it’s hot and ready when your casserole is assembled.
2. Sauté the Vegetables:
In a large skillet over medium heat, pour in the olive oil. Once heated, add the chopped onion and minced garlic. Sauté them for about 3-4 minutes until they become fragrant and the onions are translucent. This will add a delicious base flavor to your casserole!
3. Cook the Ground Beef:
Add the ground beef to the skillet with the onions and garlic. Cook it while breaking it up with a spoon until it’s browned and fully cooked, which should take around 6-8 minutes. Make sure to drain any excess fat so your casserole isn’t too greasy.
4. Add the Peppers:
Next, stir in the diced bell peppers. Cook these for another 5 minutes until they soften slightly. The colors will start to brighten up your dish!
5. Combine the Ingredients:
Pour in the diced tomatoes (with the juice), tomato sauce, Italian seasoning, salt, and pepper into the skillet. Stir everything together and let it simmer for about 5 minutes. This will help meld all those lovely flavors.
6. Mix in the Rice and Cheese:
Remove the skillet from the heat. Add in the cooked rice and half of the shredded cheddar cheese, stirring everything together until combined.
7. Transfer to Baking Dish:
Grease a 9×13-inch baking dish with a little olive oil or cooking spray. Pour the mixture into the dish and spread it out evenly. Sprinkle the remaining cheese on top so it gets melty and bubbly as it bakes!
8. Bake the Casserole:
Place the baking dish in the preheated oven and bake uncovered for 20-25 minutes. You’ll know it’s done when the cheese is melted and bubbling beautifully.
9. Serve and Enjoy:
Once it’s out of the oven, let the casserole rest for a few minutes before serving. This allows everything to set a little, making it easier to scoop out portions. Enjoy your hearty and delicious easy stuffed pepper casserole!
FAQ for Easy Stuffed Pepper Casserole
Can I Use Brown Rice Instead of White Rice?
Absolutely! Brown rice can be a healthier option, but it does take longer to cook. Be sure to pre-cook the brown rice according to package instructions before adding it to the casserole mixture.
How Long Will Leftovers Last?
Your leftovers can be stored in an airtight container in the fridge for up to 3-4 days. Simply reheat in the microwave or in the oven until warmed through for a quick meal!
Can I Make This Recipe Ahead of Time?
Yes! You can prepare the casserole and assemble it the night before. Just cover it tightly with plastic wrap and store it in the fridge. When you’re ready to bake, remove it from the fridge, let it sit at room temperature for about 30 minutes, and then bake as directed.
What Can I Use Instead of Ground Beef?
If you’d like to make the casserole lighter, try using ground turkey or chicken. For a vegetarian option, you can substitute with black beans, lentils, or a plant-based meat alternative!
