A Classic Dish Turned Into a Comforting Casserole

Stuffed peppers have been enjoyed for centuries, with variations appearing in cuisines across the Mediterranean, Eastern Europe, and even Latin America. Traditionally, bell peppers are hollowed out and filled with a mixture of rice, meat, vegetables, and seasonings before being baked. This easy stuffed pepper casserole simplifies the process by layering all the flavors into one skillet or baking dish—no need to stuff each pepper individually. The result is a warm, hearty, and cheesy dish that captures all the flavor of stuffed peppers in a much easier, family-friendly format.

Why the Ingredients Work Perfectly Together

Each ingredient in this casserole plays a key role in creating balance. Ground beef provides hearty protein and rich flavor, while bell peppers and onions add freshness and natural sweetness. Garlic and Worcestershire sauce deepen the flavor, making the dish savory and aromatic. Long-grain rice absorbs the beef broth and tomato juices, giving the casserole a comforting texture. Finally, mozzarella and cheddar cheeses create a creamy, gooey finish that makes this meal irresistible. Together, these ingredients create a dish that is both satisfying and well-rounded, with the right mix of protein, carbs, and vegetables.

The best thing about this stuffed pepper casserole is its convenience. It takes less time than traditional stuffed peppers, yet it delivers the same comforting taste. Everything cooks in one pan, making cleanup simple. This dish is also versatile—you can swap ground beef for turkey, chicken, or even plant-based protein. It’s freezer-friendly, reheats beautifully, and makes an excellent option for meal prep. Whether you’re serving a weeknight dinner, bringing a dish to a potluck, or prepping make-ahead meals, this casserole is sure to please both kids and adults.

Ingredients

• 1 pound ground beef
• 2 bell peppers, chopped
• 1 onion, finely chopped
• 3 cloves garlic, minced
• 1 tablespoon Worcestershire sauce
• 1 (15 oz) can low-sodium beef broth
• 1 (15 oz) can diced tomatoes
• 1 cup uncooked long-grain white rice
• 1 tablespoon Italian seasoning
• 1 teaspoon salt
• ½ teaspoon black pepper
• ¾ cup mozzarella cheese, shredded
• ¾ cup cheddar cheese, shredded

Step-by-Step Instructions

Step 1 – Cook the Ground Beef

In a large skillet over medium heat, brown the ground beef, breaking it into small pieces as it cooks. Drain excess grease if needed.

Step 2 – Add Vegetables

Stir in the chopped bell peppers and onion. Cook for 4–5 minutes until softened.

Step 3 – Add Garlic and Seasonings

Mix in the minced garlic, Worcestershire sauce, beef broth, diced tomatoes, rice, Italian seasoning, salt, and pepper. Stir until everything is well combined.

Step 4 – Simmer the Casserole

Bring the mixture to a boil, then reduce the heat to low. Cover and let simmer for 20 minutes, or until the rice is fully cooked and tender. Stir occasionally to prevent sticking.

Step 5 – Add the Cheese

Once the rice is cooked, stir in half of the mozzarella and cheddar cheeses until melted and creamy.

Step 6 – Finish with Cheese Topping

Sprinkle the remaining cheese evenly over the top. Cover until melted, or place the skillet under the broiler for 2–3 minutes for a bubbly, golden top.

Step 7 – Serve and Enjoy

Scoop the casserole into bowls and serve hot. Garnish with fresh parsley if desired.

Stuffed Pepper Casserole

Q1: Can I use brown rice instead of white rice?

Yes, but brown rice takes longer to cook. You’ll need to simmer for about 40–45 minutes, and you may need to add more broth to prevent drying out.

Q2: Can I make this casserole ahead of time?

Definitely! You can prepare the casserole up to the cheese step, let it cool, and refrigerate for up to 2 days. When ready to serve, reheat and add the cheese topping fresh.

Q3: Can I freeze stuffed pepper casserole?

Yes, this recipe freezes very well. Allow it to cool completely, store in a freezer-safe container, and freeze for up to 3 months. Reheat in the oven or microwave until hot.

Q4: What other proteins can I use?

Ground turkey, chicken, or even sausage work well in this casserole. For a vegetarian option, you can use lentils, quinoa, or plant-based ground meat.

Q5: What side dishes go well with stuffed pepper casserole?

It pairs perfectly with a simple side salad, garlic bread, or roasted vegetables. Since it’s hearty on its own, you don’t need much more to make a complete meal.
