Set your oven to 375°F (190°C) and lightly butter a square baking dish (9x9 inches).

Throw the beef, breadcrumbs, milk, egg, onion, garlic powder, salt, pepper, half the ketchup, and Worcestershire sauce in a bowl. Stir everything together until it’s evenly combined.

Press the meat mixture into your baking dish. Spread the rest of the ketchup over the top. Pop it in the oven and let it bake for 20-25 minutes, or until it’s fully cooked.

Spread the mashed potatoes over the meat once it’s done baking. Sprinkle the top with shredded cheese and crumbled bacon bits.

Put it back in the oven for another 10-15 minutes, or until the cheese melts into gooey perfection.

If you like, sprinkle chopped green onions or chives over the dish. Let it sit for a few minutes before slicing and serving.
