Turn your oven to 375°F (190°C) to warm up. Coat a 9x9-inch baking pan lightly with oil or butter.
02 -
Throw together the ground beef, breadcrumbs, onion, egg, milk, salt, pepper, garlic powder, Worcestershire sauce, and half your ketchup. Stir until combined.
03 -
Push the beef mixture down into the pan evenly. Spread the rest of the ketchup all over. Cook in the oven for 20-25 minutes, making sure it’s done all the way through.

After baking, slather mashed potatoes on top of the meat. Sprinkle on bacon and cheese.
05 -
Pop the pan back in the oven for another 10-15 minutes, just until the cheese bubbles and melts.
06 -
Add a bit of chopped green onion or chives for a pop of freshness if you'd like. Let things cool a bit, then dish it up.
