Preheat your oven to 400°F (200°C). Gather your ingredients and a large skillet.

In the skillet, cook 1 lb of ground beef and 0.5 cup of chopped onion over medium heat for 8-10 minutes until browned. Drain excess fat and season with salt and pepper.

In a mixing bowl, combine the beef mixture with 0.5 cup of shredded cheddar cheese, 0.5 cup of milk, 3 large eggs, 1 cup of all-purpose flour, 1 tsp of baking powder, and 1 tsp of garlic powder. Mix until smooth.

Grease a 9-inch pie dish and pour the filling into it, smoothing the top.

Sprinkle with 0.5 cup of shredded cheddar cheese.

Bake in the oven for 25-30 minutes until golden brown and set.

Let the pie cool for a few minutes, then serve warm with your favorite toppings.
