INGREDIENTS:
cooking spray
1 pound lean (at least 80%) ground beef
1 large onion, chopped
1 cup milk
0.5 cup Original Bisquick mix
2 large eggs
0.5 teaspoon salt
1 cup shredded Cheddar cheese
DIRECTIONS:
Preheat the oven to 400 degrees F (200 degrees C). Spray 9-inch glass pie pan with cooking spray.
Cook beef and onion in a nonstick skillet over medium heat, stirring occasionally, until beef is browned and crumbly, 8 to 10 minutes.
Meanwhile, whisk milk, Bisquick, and eggs together in a small bowl.
Drain beef and onion mixture; transfer to the prepared pie pan. Stir in salt, sprinkle with Cheddar, and pour Bisquick mixture over top.
Bake in the preheated oven until a knife inserted in the center comes out clean, about 25 minutes.
