Tip: save now, cook later.Stuffed Pepper Casserole is a cozy, easy-to-make dish that brings the flavors of classic stuffed peppers into a comforting casserole form. It’s packed with tender ground beef or turkey, colorful bell peppers, fragrant rice, and a rich tomato sauce that all come together in one delicious, cheesy bake. It’s a hearty meal that tastes like a big homemade hug on a plate.
I love this casserole because it’s super simple to put together, but it still feels special and satisfying. Instead of stuffing peppers one by one, you just mix everything and bake it all at once, which saves time and mess. I often add a little extra cheese on top because, well, who doesn’t love a gooey, melty cheese finish?
My favorite way to serve Stuffed Pepper Casserole is with a side of fresh green salad or some crusty bread to soak up the juicy tomato sauce. It’s the kind of dish that everyone asks for again and again at family dinners, and I always feel like it brings people together around the table. Plus, leftovers taste just as good the next day, making this a perfect make-ahead meal!
Key Ingredients & Substitutions
Ground Beef or Turkey: Ground beef adds rich flavor, but lean ground turkey is a lighter alternative that still works well. You can also use plant-based ground meat for a vegetarian twist.
Bell Peppers: Red, yellow, or green peppers all bring crunch and sweetness. Use whatever color you like or have on hand. If peppers are not available, you can add diced zucchini or mushrooms instead.
Rice: Uncooked long-grain white rice is perfect here because it cooks in the sauce. If you prefer, you can swap for brown rice, but increase baking time and broth accordingly.
Cheese: Sharp cheddar melts nicely and adds tang. Mixing cheddar with mozzarella gives a gooey texture. For a dairy-free version, try vegan cheese or omit it and sprinkle fresh herbs for flavor.
How Do You Ensure the Rice Cooks Perfectly in the Casserole?
The rice needs to become tender while baking without ending up mushy or dry. Here’s how to get it right:
- Use the right amount of liquid—2 cups of broth or bouillon to cook 1 cup of rice works well.
- Simmer the mixture briefly on the stove before baking, which starts cooking the rice and blends flavors.
- Cover the dish tightly with foil during baking to trap steam and help rice cook evenly.
- Check the casserole toward the end of baking; the rice should be tender but not too soft.
- Let the casserole sit a few minutes after baking. It helps the rice absorb any remaining moisture, making the texture just right.
Equipment You’ll Need
- Large skillet – perfect for browning the meat and sautéing veggies all in one pan.
- Measuring cups and spoons – help you get the rice, broth, and seasonings just right.
- 9×9-inch casserole dish – great size for baking and layering all ingredients evenly.
- Aluminum foil – keeps the casserole moist while baking.
- Wooden spoon or spatula – sturdy for stirring the mixture without scratching cookware.
Flavor Variations & Add-Ins
- Swap ground beef for Italian sausage for a spicier, more flavorful dish.
- Add chopped mushrooms or zucchini for extra veggies and texture.
- Use pepper jack cheese instead of cheddar for a little kick and creaminess.
- Mix in cooked quinoa instead of rice for more protein and a nuttier flavor.

How Much Time Will You Need?
This casserole takes about 15 minutes of preparation and about 35-40 minutes baking time. In total, expect around 50-55 minutes from start to finish, including sautéing, simmering, and baking with cheese on top.
Step-by-Step Instructions:
1. Get Started with the Base:
Preheat your oven to 375°F (190°C). Heat the olive oil in a large skillet over medium heat. Add the chopped onion and sauté for 3-4 minutes until soft. Stir in the minced garlic and cook for another 30 seconds until fragrant.
2. Cook the Meat and Peppers:
Add the ground beef to the skillet, breaking it up as you cook until browned and fully cooked through. Drain any excess fat. Stir in the diced bell peppers and cook for 3-4 minutes until they start to soften.
3. Mix in Rice, Tomatoes, and Seasonings:
Add the uncooked rice to the pan and stir well to combine. Pour in the beef broth, drained diced tomatoes, tomato sauce, Italian seasoning, smoked paprika (if using), salt, and black pepper. Stir everything together and bring the mixture to a simmer. Cook uncovered for about 5 minutes until the liquid reduces slightly but the rice is not fully cooked yet.
4. Bake the Casserole:
Transfer the mixture evenly into a greased 9×9 inch casserole dish. Cover tightly with aluminum foil and bake in your preheated oven for 25-30 minutes or until the rice is tender.
5. Cheese It and Finish Baking:
Remove the foil and sprinkle the shredded cheese evenly over the top. Bake uncovered for another 5-10 minutes until the cheese is melted and bubbly.
6. Garnish and Serve:
Take the casserole out of the oven and let it cool a bit. Sprinkle with chopped green onions and fresh parsley or cilantro. Serve warm with your favorite side like a fresh salad or crusty bread.
Can I Use Frozen Peppers in This Recipe?
Yes, you can! Just make sure to thaw them completely and drain any excess moisture before adding to the skillet. This helps prevent the casserole from becoming too watery.
Can I Prepare Stuffed Pepper Casserole Ahead of Time?
Absolutely! You can assemble the casserole a day ahead, keep it covered in the fridge, and bake it fresh when ready. You might need to add a few extra minutes to the baking time if it’s chilled.
How Should I Store Leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, microwave or warm in the oven until heated through. Adding a splash of broth can help keep it moist.
What Can I Substitute for Ground Beef?
Ground turkey, chicken, or even plant-based meat alternatives work great. Just adjust cooking times until the meat is fully cooked and maintain the same seasoning to keep flavor balanced.
