Meaty Stuffed Pepper Casserole

Step 1
Preheat oven to 350 degrees F (175 degrees C).

Step 2
Melt butter in a large pot over medium heat; cook and stir green bell peppers, onion, and garlic in the hot butter until vegetables are slightly soft, 2 minutes. Stir sausage and ground beef into bell pepper mixture; cook until meat is crumbly and browned, stirring often, 10 to 12 minutes. Drain grease. Season mixture with salt, black pepper, oregano, and garlic powder.

Step 3
Mix diced tomatoes, rice, tomato paste, and Worcestershire sauce into meat mixture and bring to a simmer; cook until heated through, about 5 minutes, stirring occasionally. Pour mixture into a large baking dish.

Step 4
Whisk tomato soup with water in a bowl until smooth; pour soup over meat mixture. Spread Cheddar cheese over casserole.

Step 5
Bake in the preheated oven until casserole is heated through and Cheddar cheese is browned and bubbling, about 30 minutes.
