What is a Stuffed Bell Pepper Casserole?

The casserole version retains all the delicious flavors of the original dish but in a more approachable and simplified format.

Step-by-Step Cooking Instructions

Follow these easy steps to prepare your Stuffed Bell Pepper Casserole.
1. Preheat the Oven
Preheat your oven to 375°F (190°C). While the oven heats up, gather all your ingredients and prepare your vegetables.
2. Cook the Rice
In a medium saucepan, cook the rice according to the package instructions, using beef or vegetable broth instead of water for added flavor. Set aside once fully cooked.
3. Brown the Ground Meat
In a large skillet, brown the ground beef or turkey over medium heat until fully cooked. Drain any excess grease and set the meat aside in a bowl.
4. Sauté the Vegetables
In the same skillet, add a little olive oil and sauté the chopped onion, bell peppers, and garlic until the vegetables are softened, about 5-7 minutes.
5. Combine Ingredients
Add the cooked meat, diced tomatoes, tomato sauce, Italian seasoning, smoked paprika, and cooked rice to the skillet with the sautéed vegetables. Stir everything together until well mixed. Season with salt and pepper to taste.
6. Assemble the Casserole
Transfer the mixture into a greased 9x13-inch casserole dish. Spread it out evenly and top with shredded mozzarella and Parmesan cheese.
7. Bake the Casserole
Place the casserole dish in the preheated oven and bake for 25-30 minutes, or until the cheese is melted and bubbly.
8. Garnish and Serve
Once the casserole is done, remove it from the oven and let it cool for 5 minutes. Garnish with freshly chopped parsley or basil before serving.
How to Cook Stuffed Bell Pepper Casserole: A Step-by-Step Guide
Cooking Stuffed Bell Pepper Casserole is as simple as combining the right ingredients and baking them to perfection. The key to a successful casserole is balancing the flavors and textures. Here's a quick overview of the steps to follow for perfect results:
- Prep the ingredients: Chop the bell peppers, onions, and garlic. Cook the rice and brown the meat.
- Layer flavors: Sauté the vegetables to bring out their sweetness, and combine them with seasoned meat, rice, and tomatoes.
- Cheese it up: Use a generous layer of cheese for that gooey, melty topping.
- Bake until bubbly: The casserole is done when the cheese is golden and bubbly.
Common Mistakes to Avoid
Even though this recipe is easy, there are a few common mistakes to watch out for:
- Overcooking the Bell Peppers: If you sauté the bell peppers for too long, they may become mushy. Cook them just until they start to soften.
- Dry Casserole: Avoid using too little liquid. The canned tomatoes and broth help keep the casserole moist, so be sure not to skimp on them.
- Not Draining the Meat: If you don’t drain the grease from the cooked ground meat, it can make the casserole overly greasy.
- Burnt Cheese: While a crispy cheese layer is delicious, burnt cheese is not. Keep an eye on the casserole during the last 5 minutes of baking to avoid burning the top.
- Undercooked Rice: Make sure the rice is fully cooked before adding it to the casserole. Undercooked rice will remain hard and chewy even after baking.
Serving and Presentation Tips
Presentation matters, especially if you're serving this casserole at a gathering. Here are a few tips for making your Stuffed Bell Pepper Casserole look as good as it tastes:
- Use a cast-iron skillet or a beautiful ceramic casserole dish for baking and serving. It saves on dishes and looks more elegant.
- Add fresh herbs on top just before serving to give the casserole a burst of color and freshness.
- Serve with a side salad for balance and color contrast, such as a bright green arugula or spinach salad with a light vinaigrette.
How to Serve Stuffed Bell Pepper Casserole
Stuffed Bell Pepper Casserole is a complete meal on its own, but you can serve it alongside a few complementary dishes for a more well-rounded meal. Here are a few serving ideas:
- Crusty Bread: A slice of warm, crusty bread is perfect for soaking up the flavorful tomato sauce.
- Side Salad: A simple green salad with a tangy vinaigrette can balance out the richness of the casserole.
- Steamed Vegetables: Serve with lightly steamed or roasted vegetables like broccoli, green beans, or carrots for added nutrients.

For an Instagram-worthy presentation, try these creative ideas:
