This easy-to-make dish combines the flavors of a classic cheeseburger with a flaky Bisquick crust for a satisfying meal.
In a skillet, cook the ground beef and chopped onions until the meat is browned and the onions are tender. Drain any excess fat.
Stir in ketchup, yellow mustard, salt, and black pepper to the cooked beef mixture, creating a cheeseburger-flavored filling.
Spread the beef mixture evenly in a greased pie dish. Sprinkle shredded cheddar cheese over the top.
In a bowl, mix Bisquick mix, milk, and eggs to create a Bisquick crust batter.
Pour the Bisquick crust batter over the beef and cheese filling, covering it completely.
