Barbeque Beef Bake

1 pound ground beef

¾ cup chopped onion

1 cup barbeque sauce

2 cups shredded Cheddar cheese

2 cups baking mix (such as Bisquick ®)

2 eggs

1 cup milk

Preheat an oven to 400 degrees F (200 degrees C).

Cook the ground beef and onion together in a large skillet over medium heat until the beef is completely browned; stir the barbeque sauce and Cheddar cheese into the ground beef. Pour the mixture into a 9x13-inch dish.

Whisk the baking mix, eggs, and milk together in a bowl; pour over the beef mixture.

Bake in the preheated oven until the crust is golden brown and cooked throughout, about 25 minutes.
