Preheat the oven to 400 °F. Spray a 9-inch pie plate with nonstick cooking spray.
In a large skillet, cook the ground beef (1 pound), onion (1), garlic (2 cloves), Worcestershire sauce (1 tablespoon), 1 teaspoon salt, and pepper (1/2 teaspoon) over medium heat, until beef is brown and there is no longer any pink, about 10 minutes. Remove excess fat. Pour cooked beef into the prepared pie plate.
In a small mixing bowl, whisk together crust ingredients. Pour it over to the beef mixture. Sprinkle evenly with cheese (1 cup). Bake in the preheated oven until the top is golden, about 30-40 minutes. Remove from oven and allow to rest for 10 minutes before serving.
Notes
Bake: I always bake mine uncovered. It allows the air to circulate so the pie bakes up nice and even with a perfectly golden cheesy crust.
Feed a crowd: If you want to stretch out the meal a bit, you can double the impossible concoction and fill up a 9” x 13” pan instead.
You can also make cute little individual pies by baking this in muffin tins!
Mix all the ingredients, then fill a lightly greased pan with a scant tablespoon of the Bisquick batter, ¼ c. of the beef filling, then another tablespoon of the batter.
They’ll need to bake for about 30 minutes, cool for 5, then be taken out to cool for another 10 minutes to avoid any impatient mouth burning.
Fillings + Toppings – Make this a bacon cheeseburger pie by adding about 6 slices of cooked and crumbled bacon to the beef before adding the Bisquick batter. Some impossible cheeseburger pie recipes add ketchup, mustard, or even dill pickle relish to the filling to emulate an actual cheeseburger.
I like to save those things for garnish since no two guests are exactly alike when it comes to hamburger fixin’s.
How To Check Doneness - The center will be set, the top golden, and a knife inserted into the center will come out clean.
