Stuffed Pepper Casserole

Introduction

Stuffed Pepper Casserole is a hearty, comforting dinner that brings together everything people love about traditional stuffed peppers in one easy-to-serve dish. Instead of filling individual peppers, this casserole combines seasoned ground beef, colorful bell peppers, tender rice, tomatoes, aromatic garlic and onion, and plenty of melted cheddar cheese. The result is a warm, satisfying meal with rich savory flavors in every bite.

This recipe is especially good for busy family dinners because it uses simple, familiar ingredients and doesn’t require complicated preparation. The combination of beef and rice makes it filling, while the bell peppers and tomatoes add freshness, color, and a subtle sweetness. A generous layer of cheddar melts over the top as the casserole bakes, creating the irresistible cheesy finish that makes this dish a true comfort-food favorite.

Ingredients

1 pound (450 g) ground beef
2 bell peppers, chopped
1 medium onion, finely chopped
2 cloves garlic, minced
1 can (14.5 oz / 411 g) diced tomatoes, with juices
1 cup cooked rice
1 cup shredded cheddar cheese
1 teaspoon salt
1/2 teaspoon ground black pepper
1 teaspoon Italian seasoning
1 tablespoon olive oil

Optional garnish: chopped fresh parsley

Preparation

1. Prepare the Oven and Baking Dish

Preheat the oven to 375°F (190°C). Lightly grease a medium casserole or baking dish and set it aside while you prepare the filling.

2. Cook the Ground Beef

Heat the olive oil in a large skillet over medium-high heat. Add the ground beef and cook for about 5–7 minutes, breaking it into small pieces with a wooden spoon as it browns.

Once the beef is completely cooked, carefully drain any excess grease from the skillet if necessary.

3. Add the Vegetables

Add the finely chopped onion and chopped bell peppers to the browned beef. Cook for approximately 4–5 minutes, stirring occasionally, until the onion begins to soften and the peppers become slightly tender.

Add the minced garlic and continue cooking for about 30–60 seconds, just until fragrant. Avoid cooking the garlic for too long so it does not burn.

4. Season the Filling

Stir in the diced tomatoes along with their juices. Add the salt, black pepper, and Italian seasoning.

Mix everything together thoroughly and allow the mixture to simmer gently for about 3–5 minutes. This gives the tomatoes and seasonings time to blend with the beef and vegetables.

5. Add the Rice

Add the cooked rice to the skillet and gently stir until it is evenly distributed throughout the beef and pepper mixture.

Continue cooking for another 2 minutes so the rice can absorb some of the tomato juices and savory seasonings. Taste the mixture and adjust the salt or pepper if desired.

6. Assemble the Casserole

Transfer the beef, pepper, tomato, and rice mixture into the prepared baking dish. Spread it into an even layer, making sure the ingredients are distributed throughout the casserole.

Sprinkle the shredded cheddar cheese generously and evenly over the entire surface.

7. Bake

Place the casserole in the preheated oven and bake uncovered for approximately 20–25 minutes, or until the filling is hot and bubbling around the edges and the cheddar cheese has completely melted.

For a slightly more golden cheese topping, you can broil the casserole for the final 1–2 minutes, watching it carefully to prevent burning.

8. Rest and Serve

Remove the casserole from the oven and allow it to rest for about 5 minutes before serving. This short resting period helps the filling settle and makes it easier to portion.

Finish with a little freshly chopped parsley if desired and serve warm.

Serving Suggestions

Stuffed Pepper Casserole is substantial enough to serve as a complete meal on its own, but it also pairs beautifully with a crisp green salad, roasted vegetables, steamed green beans, or warm garlic bread. For an extra cheesy serving, sprinkle a little additional cheddar over each portion while the casserole is still hot.

Leftovers can be stored in an airtight container in the refrigerator and reheated for another quick and comforting meal.

This Stuffed Pepper Casserole takes the familiar flavors of classic stuffed peppers and turns them into a simple, family-style dinner.
