  • 13"x9" casserole dish


  • 1 pound lean ground beef
  • 2 bell peppers (whatever color you like), DICED
  • 1 medium onion, diced
  • 3-4 cloves garlic, minced
  • salt and pepper, to taste
  • 2 teaspoons Italian Seasoning
  • 3 tablespoons tomato paste
  • 1 can (14.5 ounces) fire-roasted tomatoes, do not drain
  • 3 cups unsalted or low sodium beef broth
  • 1 1/2 cups uncooked long grain rice
  • 2 cups shredded colby jack cheese (or your favorite cheese)


  • Preheat oven to 350 degrees and spray a 9"x13" casserole dish with non-stick spray
  • In a large skillet (over medium-high heat) brown ground beef until nearly done. Add the diced peppers, onions, and garlic. Continue cooking until the ground beef is done and the vegetables are soft. Drain excess grease, if any.
  • Place beef mixture in prepared casserole dish. Add in the tomatoes, Italian seasoning, salt, pepper, tomato paste, beef broth, and uncooked rice. Stir well to make sure everything is incorporated.
  • Cover tightly with aluminum foil and place in oven. Bake for 1 hour, stir the mixture halfway through cooking time. This ensures the all the rice will get cooked evenly. Casserole is done when the rice is completely cooked and tender.
  • Remove from oven and take the foil off. Top casserole with cheese and pop back into the oven for about 5 minutes, or until the cheese is completely melted.
  • Some casseroles need to be made using a skillet and then baked in a casserole dish. That's how I made this meal the first time, which is this recipe. However, if you have a deep oven-safe pan with high sides, you can make this casserole in one pan from start to finish.


  • Using lean ground beef (93% lean) will cut down on the grease
  • Try using all ground sausage or half beef and half sausage. Ground turkey is great, too.
  • Frozen diced peppers do not do well in this recipe; they'll be to soft.
  • If you prefer to use regular diced tomatoes, that's fine. The fire-roasted add so much more flavor, in my opnion.
  • Use whatever bell peppers you like, or a combination.
  • Can you freeze this casserole? Yes, bake the casserole as directed. Allow to cool completely then wrap tightly with foil and freeze. Allow casserole to thaw before reheating in oven.
