Ingredients

  • ½ lb. ground Italian sausage
  • ½ lb. ground beef
  • 1 large sweet onion, diced
  • 2 cloves garlic, minced or pressed
  • 3 medium green bell peppers, seeded and diced
  • 1 (14.5 ounce) can diced tomatoes, NOT drained
  • 1 (29 ounce) can tomato sauce
  • 1 tablespoon soy sauce
  • 2 teaspoons Italian seasoning
  • 1 teaspoon sugar
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • Salt and pepper, to taste
  • 3 cups cooked white rice
  • 1 cup shredded Cheddar Jack cheese, or more to taste
  • Optional garnish: chopped fresh parsley

Instructions

  • Preheat oven to 350°F. Grease a deep 9 x 13-inch baking dish; set aside.
  • In a large Dutch oven, brown the sausage, ground beef, onion and garlic over medium-high heat until the meat is no longer pink; drain off fat.
  • Stir in the bell peppers, diced tomatoes with juices, tomato sauce, soy sauce, Italian seasoning, sugar, garlic powder, onion powder, salt and pepper. Bring the mixture to a simmer, then reduce the heat to low, cover and simmer gently for 10-15 minutes, stirring occasionally. Remove from the heat. Stir in the rice.
  • Transfer the mixture the prepared baking dish. Top with shredded cheese.
  • Bake for 20 minutes, or until the cheese is melted and the casserole is hot and bubbly. Let stand for 10 minutes before serving. Garnish with fresh parsley.

Notes

  • Make sure that you purchase the large 29-ounce can of tomato sauce. You need plenty of sauce so that the casserole stays nice and moist and doesn't dry out in the oven.
  • For a shortcut, use leftover rice from the night before or a packet of microwaveable rice (like Uncle Ben's Ready Rice).
  • Garnish the finished dish with fresh herbs just before serving. They add a colorful, fresh touch!
  • Use red, orange or yellow peppers if you prefer a sweeter taste. Green bell peppers provide a zestier bite.
  • Bake the casserole just until it's heated through. All of the ingredients are already cooked, so you just want to warm it in the oven until bubbly.
  • Cooking for a smaller family? Cut all of the ingredients in half and bake the casserole in an 8-inch square dish. The rest of the cooking instructions remain the same.
  • Divide the casserole ingredients between two 8-inch square baking dishes. Bake one now, and freeze the other for a later meal.
