How to Make Cheesy Stuffed Pepper Casserole
Step 1: Prepare the Oven and Baking Dish
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish and set aside.
Step 2: Cook the Meat
Heat a large skillet over medium heat.
Add the ground beef or turkey and cook until browned, breaking it apart with a spoon.
Drain excess fat if needed.
Add the chopped onion and cook for 3–4 minutes until softened.
Stir in the minced garlic and cook for another 30 seconds until fragrant.
Step 3: Add the Peppers and Seasonings
Add the diced bell peppers to the skillet.
Cook for several minutes until they begin to soften while still maintaining some texture.
Add:
- Italian seasoning
- Paprika
- Salt
- Black pepper
- Worcestershire sauce
Stir everything together.
Step 4: Combine the Filling
Add:
- Cooked rice
- Tomato sauce
- Diced tomatoes
Mix well until all ingredients are evenly combined.
Allow the mixture to simmer for about 5 minutes so the flavors blend together.
Step 5: Assemble the Casserole
Transfer the mixture into the prepared baking dish.
Spread it evenly.
Sprinkle mozzarella and cheddar cheese over the top.
Make sure the cheese covers the surface for a delicious golden crust.
Step 6: Bake Until Cheesy and Golden
Cover the dish with foil and bake for 20 minutes.
Remove the foil and bake for an additional 10–15 minutes until the cheese is melted, bubbly, and lightly golden.
Let the casserole rest for 5 minutes before serving.
Tips for the Best Stuffed Pepper Casserole
Use Fresh Bell Peppers
Fresh peppers provide the best flavor and texture.
A combination of red, yellow, and green peppers adds sweetness and color.
Cook Rice Ahead of Time
Using leftover cooked rice makes this recipe faster and helps prevent the casserole from becoming too watery.
Choose the Right Cheese
Mozzarella creates a stretchy, melty texture, while cheddar adds a sharper flavor.
A combination of cheeses gives the best result.
Don’t Overcook the Peppers
Cooking peppers until they are slightly tender before baking keeps them from becoming mushy.
Let the Casserole Rest
Allowing the casserole to sit for a few minutes after baking helps the flavors settle and makes serving easier.

Common Mistakes to Avoid
Using Uncooked Rice Without Adjusting Liquid
Raw rice absorbs liquid during cooking and may change the texture. Use cooked rice unless the recipe is specifically designed for uncooked rice.
Adding Too Much Sauce
Excess liquid can make the casserole watery. Use measured amounts for the best consistency.
Skipping Seasoning
The meat, rice, and peppers need enough seasoning to create a rich, flavorful dish.
Overbaking
Too much baking time can dry out the filling and make the peppers too soft.
