Stuffed Bell Pepper Casserole combines ground beef, rice, bell peppers, and tomatoes in one delicious, cheesy dish. This easy, one-pan recipe is a simplified version of traditional stuffed peppers and is perfect for weeknight dinners, meal prepping, or feeding a crowd.

Ingredients

For the casserole:

  • 1 pound lean ground beef

  • 2 large bell peppers, diced

  • 1 medium onion, diced

  • 3 cloves garlic, minced

  • 1 ½ cups beef broth

  • 15 ounces diced tomatoes

  • 1 cup long grain white rice, uncooked

  • 2 cups shredded cheese (cheddar, mozzarella, or a blend)

  • 3 tablespoons Worcestershire sauce

  • 1 ½ teaspoons Montreal Grill Seasoning

  • ½ teaspoon salt

  • ½ teaspoon pepper

  • ½ teaspoon smoked paprika

Instructions

  • Preheat the Oven:
    Preheat your oven to 375°F (190°C). Grease a 9×13-inch casserole dish with nonstick spray.

  • Cook the Ground Beef:
    In a large skillet over medium heat, brown the ground beef until fully cooked.

  • Sauté the Vegetables:
    Add the diced bell peppers, onion, and minced garlic to the skillet. Cook until the vegetables are softened, about 5 minutes.

  • Season the Mixture:
    Stir in Worcestershire sauce, Montreal Grill Seasoning, salt, pepper, and smoked paprika.

  • Add the Rice and Liquids:
    Add the diced tomatoes (with their juices), beef broth, and uncooked rice. Mix well to combine.

  • Assemble the Casserole:
    Transfer the mixture to the prepared casserole dish. Cover with aluminum foil and bake for 45 minutes, or until the rice is tender and the liquid is absorbed.

  • Add Cheese:
    Remove the foil and sprinkle the shredded cheese evenly over the top. Return to the oven and bake for an additional 5–7 minutes, until the cheese is melted and bubbly.

  • Cool and Serve:
    Let the casserole sit for 10 minutes before serving.

Notes

Vegetarian Version: Substitute the ground beef with a plant-based protein or additional vegetables like mushrooms and zucchini.Spicy Kick: Add diced jalapeños or a teaspoon of chili flakes for heat.Different Grains: Use quinoa or brown rice instead of white rice for a different texture.
