1 medium yellow onion, finely diced
3 bell peppers, any color, diced
3 cloves garlic, minced
1 cup uncooked long grain white rice
2 tablespoons tomato paste
1 teaspoon paprika
1 teaspoon dried oregano
1 teaspoon sea salt
1 half teaspoon black pepper
2 cups beef broth
1 can crushed tomatoes, 14 ounces

For the Topping

1 cup shredded mozzarella cheese
1 half cup shredded cheddar cheese
2 tablespoons chopped fresh parsley

Substitution Notes

Brown rice can replace white rice, but cooking time will increase and more broth may be needed.
Cauliflower rice can replace traditional rice for a lower carb version. Reduce broth to 1 cup if using cauliflower rice.
Monterey Jack or provolone may replace mozzarella.

Step by Step Instructions

Step 1: Prepare the Vegetables

Heat olive oil in a large skillet over medium heat. Add the diced onion and cook for about 3 minutes until translucent. Add the diced bell peppers and cook for another 5 to 6 minutes. Stir occasionally. The goal is to soften the peppers and reduce excess moisture.
Add minced garlic and cook for 30 seconds until fragrant. Transfer the vegetable mixture to a bowl and set aside.

Step 2: Brown the Ground Beef

In the same skillet, add the ground beef. Cook over medium heat, breaking it apart with a wooden spoon. Continue until no pink remains. Drain excess fat if necessary.
Return the sautéed vegetables to the skillet with the beef. Stir to combine.

Step 3: Build the Flavor Base

Add tomato paste, paprika, oregano, salt, and black pepper to the skillet. Stir well so the tomato paste coats the meat and vegetables evenly. Cook for 2 minutes to deepen the flavor.
Pour in crushed tomatoes and beef broth. Stir to combine. Add uncooked rice and mix thoroughly so the grains are evenly distributed.

Step 4: Assemble the Stuffed Bell Peppers Casserole

Preheat the oven to 375 degrees Fahrenheit.
Transfer the entire mixture to a lightly greased baking dish. Spread it evenly. Cover tightly with foil.
Bake for 30 minutes. Remove foil carefully and stir gently. Check that the rice is tender. If needed, return to the oven covered for an additional 5 to 10 minutes.

Step 5: Add Cheese and Finish Baking

Once the rice is tender, sprinkle mozzarella and cheddar evenly over the top. Return the casserole to the oven uncovered for 5 to 7 minutes until the cheese melts and lightly bubbles.
Remove from oven and let rest for 10 minutes before serving. This allows the structure to settle and makes slicing easier.

How to Serve

Serve stuffed bell peppers casserole straight from the baking dish for a rustic presentation. Garnish with fresh parsley for color. Pair with a crisp green salad dressed in lemon vinaigrette to balance richness. Garlic roasted broccoli or green beans also complement the sweetness of the peppers.

If serving as a dinner recipe with bell peppers for guests, spoon portions neatly into shallow bowls and top with a light sprinkle of parmesan. For meal planning, portion into containers with a side of roasted vegetables. This works well for things to make with bell peppers when planning weekly menus.

Secret Behind This Recipe

The secret to a successful stuffed bell peppers casserole is moisture control and layering flavor in stages. Sautéing the peppers first removes excess water. Browning the tomato paste before adding liquid builds depth. Allowing the casserole to rest after baking ensures the rice absorbs remaining liquid and firms slightly.

Another key detail is seasoning at each stage. The beef is seasoned, the vegetable mixture is seasoned, and the sauce is seasoned. This prevents the finished dish from tasting flat. The final result is a bell pepper casserole ground beef rice dish that feels structured and balanced rather than soggy or dry.
