This Stuffed Pepper Casserole is a delicious and comforting one-pan meal that captures the classic flavors of stuffed bell peppers without the hassle of stuffing peppers individually. Ground beef, diced onions, and colorful bell peppers are combined with rice, tomato sauce, and beef broth, then topped with melted white cheddar cheese for a hearty, cheesy finish. Perfect for an easy weeknight dinner or family gathering, this casserole delivers all the familiar flavors in a simple, baked dish.

  • Total Time: 1 hour 10 minutes
  • Yield: 6 servings

Ingredients

Main Ingredients

  • 1 lb ground beef
  • 1 onion, diced
  • 3 bell peppers (multi-colored), diced
  • 2 teaspoons garlic, minced
  • 8 oz tomato sauce
  • 1 ½ cups beef broth
  • 1 cup white rice, uncooked
  • 2 cups white cheddar cheese, shredded

Instructions

  1. Preheat the Oven: Preheat your oven to 375°F (190°C) to ensure it’s ready for baking the casserole.
  2. Sauté the Beef and Vegetables: In a large skillet over medium heat, brown the ground beef until fully cooked, breaking it apart with a spoon. Drain excess fat if necessary. Add the diced onion, diced bell peppers, and minced garlic to the skillet, sautéing until the vegetables are tender and fragrant, about 5-7 minutes.
  3. Combine Ingredients: Stir in the uncooked white rice, tomato sauce, and beef broth into the skillet with the beef and vegetables. Mix well to evenly distribute all components.
  4. Transfer to Baking Dish: Pour the mixture into a greased 9×13-inch casserole dish. Spread it out evenly to ensure uniform cooking.
  5. Bake the Casserole: Cover the casserole with aluminum foil and bake in the preheated oven for 40 minutes, allowing the rice to absorb the liquid and become tender.
  6. Add Cheese Topping: After 40 minutes, remove the foil and sprinkle the shredded white cheddar cheese evenly over the top of the casserole.
  7. Finish Baking: Return the casserole to the oven, uncovered, and bake for an additional 10-15 minutes or until the cheese is melted, bubbly, and slightly golden.
  8. Rest and Serve: Remove the casserole from the oven and let it rest for about 5 minutes before serving. This helps the casserole set and enhances flavors.

Notes

  • You can use brown rice instead of white rice, but increase the baking time and the amount of broth accordingly to ensure the rice cooks fully.
  • For a lower-fat version, substitute ground beef with ground turkey or chicken.
  • Add spices like paprika, Italian seasoning, or crushed red pepper flakes for extra flavor.
  • If you prefer a thicker casserole, reduce the beef broth to 1 cup.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
