Impossible Cheeseburger Pie

Ingredients

• 1 pound ground beef
• 1 1/2 cups chopped onion
• 1 1/2 cups milk
• 3/4 cup baking mix (such as Bisquick )
• 3 eggs
• 1/2 teaspoon Italian seasoning
• 1/2 teaspoon salt
• 1/2 teaspoon ground black pepper
• 2 tomatoes, sliced
• 1 cup shredded Cheddar cheese

Directions

Preheat oven to 400 degrees F (200 degrees C). Grease a deep-dish 9-inch pie dish.

Heat a large skillet over medium-high heat. Cook and stir beef and onion in hot skillet until browned and crumbly, 5 to 7 minutes; drain and discard grease. Spread ground beef mixture into the prepared pie dish.

Blend milk, baking mix, eggs, Italian seasoning, salt, and pepper together in a blender until smooth, about 15 seconds; pour over beef mixture.

Bake in the preheated oven until biscuit topping is lightly browned, about 25 minutes. Arrange tomato slices on biscuit topping; sprinkle with Cheddar cheese. Continue baking until cheese is melted, 5 to 8 more minutes. Cool 5 minutes before slicing.
