Cheeseburger Meatloaf with Mushroom Sauce

1 pound ground beef

1 onion, chopped

1 green bell pepper, chopped

1 cup shredded Cheddar cheese

2 tablespoons Worcestershire sauce

½ cup sour cream

1 cup crushed buttery round crackers (such as Ritz®)

1 (10.75 ounce) can condensed cream of mushroom soup

1 cup milk

1 ½ cups shredded Cheddar cheese

Preheat an oven to 350 degrees F (175 degrees C).

Mix ground beef, onion, bell pepper, 1 cup Cheddar cheese, Worcestershire sauce, sour cream, and crackers together in a bowl. Place mixture on a baking dish and shape into a loaf.

Bake in the preheated oven until no longer pink in the center, 35 to 40 minutes. An instant-read thermometer inserted into the center should read at least 160 degrees F (70 degrees C).

Heat the cream of mushroom soup, milk, and 1 1/2 cup Cheddar cheese in a saucepan over medium heat until the cheese has melted, about 10 minutes. Pour sauce over the meatloaf before serving.
