What is Stuffed Pepper Casserole?

Ingredients List for Stuffed Pepper Casserole
To make this delicious casserole, you’ll need the following ingredients:
- 1 pound of ground beef: Lean ground beef is ideal, but you can use ground turkey or chicken as a lighter option.
- 1 onion: Diced. Adds a savory base to the dish.
- 3 cloves of garlic: Minced. Garlic adds a robust flavor that complements the beef and peppers.
- 3 bell peppers: Diced. Use a mix of red, green, and yellow peppers for color and flavor.
- 1 can (15 ounces) of diced tomatoes: Undrained. The tomatoes add moisture and a bit of acidity.
- 1 can (15 ounces) of tomato sauce: This creates a rich, flavorful base for the casserole.
- 1 cup of uncooked white rice: Long-grain white rice works best, but you can use brown rice for a healthier option.
- 2 cups of beef broth: Helps cook the rice and adds depth of flavor.
- 1 teaspoon of Italian seasoning: A blend of herbs like oregano, basil, and thyme that complements the dish.
- 1 teaspoon of smoked paprika: Adds a subtle smokiness and enhances the flavor of the beef.
- Salt and pepper to taste: Essential for seasoning.
- 2 cups of shredded mozzarella cheese: Melty and delicious, this cheese tops the casserole.
- Fresh parsley for garnish: Chopped, to add a pop of color and freshness.
Substitutions and Variations
This Stuffed Pepper Casserole is highly adaptable, allowing you to make substitutions or variations based on your preferences or dietary needs. Here are some ideas:
- Ground Turkey or Chicken: For a leaner option, substitute ground turkey or chicken for the ground beef.
- Brown Rice or Quinoa: Use brown rice or quinoa instead of white rice for added fiber and nutrients. Keep in mind that brown rice will require a longer cooking time.
- Vegetarian Option: Make it vegetarian by omitting the ground beef and adding more vegetables like zucchini, mushrooms, or black beans.
- Cheese Variations: Try using cheddar, Monterey Jack, or a blend of cheeses instead of mozzarella for a different flavor profile.
- Spicy Kick: Add some heat by mixing in diced jalapeños, a pinch of cayenne pepper, or red pepper flakes.
Step-by-Step Cooking Instructions

Follow these simple steps to make your Stuffed Pepper Casserole:
1. Preheat the Oven
Preheat your oven to 375°F (190°C). This ensures the casserole bakes evenly.
2. Cook the Ground Beef
In a large skillet or Dutch oven, cook the ground beef over medium-high heat until it’s browned and fully cooked, breaking it up with a spoon as it cooks. Drain any excess fat, if necessary.
3. Sauté the Vegetables
Add the diced onion and garlic to the skillet with the browned beef. Sauté for 3-4 minutes, until the onion is softened and translucent. Then, add the diced bell peppers and cook for an additional 3-4 minutes, until the peppers are slightly softened.
4. Add the Tomatoes and Seasoning
Stir in the diced tomatoes (with their juices), tomato sauce, Italian seasoning, smoked paprika, salt, and pepper. Mix well to combine all the flavors.
5. Add the Rice and Broth
Add the uncooked rice and beef broth to the skillet, stirring to combine. Make sure the rice is evenly distributed throughout the mixture.
6. Simmer the Mixture
Bring the mixture to a gentle simmer. Cover the skillet or Dutch oven with a lid, reduce the heat to low, and let it simmer for 15-20 minutes, or until the rice is tender and has absorbed most of the liquid.
7. Transfer to a Casserole Dish
Once the rice is cooked, transfer the mixture to a lightly greased 9x13-inch casserole dish. Spread it out evenly.
8. Add the Cheese
Sprinkle the shredded mozzarella cheese evenly over the top of the casserole.
9. Bake the Casserole
Place the casserole dish in the preheated oven and bake for 15-20 minutes, or until the cheese is melted and bubbly. If you like a golden, crispy cheese topping, you can broil the casserole for the last 2-3 minutes, watching it carefully to avoid burning.
10. Garnish and Serve
Once the casserole is done baking, remove it from the oven and let it cool for a few minutes. Garnish with freshly chopped parsley and serve hot.
How to Cook Stuffed Pepper Casserole: A Step-by-Step Guide
Here are some additional tips to ensure your Stuffed Pepper Casserole turns out perfectly:
- Brown the Meat Properly: Browning the ground beef adds depth of flavor, so don’t rush this step. Make sure the beef is fully browned before adding the other ingredients.
- Cook the Rice Correctly: Ensuring the rice is tender and fully cooked is key to a successful casserole. Let the mixture simmer until the rice has absorbed most of the liquid.
- Use the Right Cheese: For the best melt and flavor, use a good-quality mozzarella cheese. Freshly shredded cheese melts better than pre-shredded cheese, which often contains anti-caking agents.
Common Mistakes to Avoid
To ensure your Stuffed Pepper Casserole turns out perfectly, avoid these common mistakes:
- Overcooking the Vegetables: Be careful not to overcook the bell peppers in the sautéing step, as they will continue to cook in the oven.
- Undercooking the Rice: Make sure the rice is fully cooked and has absorbed the liquid before transferring the mixture to the casserole dish. Undercooked rice can be hard and unpleasant to eat.
- Not Enough Seasoning: Be generous with the seasoning, especially with salt and pepper, as this dish can be bland without proper seasoning.
