1 ½ pounds ground beef

1 egg

1 onion, chopped

1 cup milk

1 cup dried bread crumbs

salt and pepper to taste

⅓ cup ketchup

2 tablespoons brown sugar

2 tablespoons prepared mustard

Preheat the oven to 350 degrees F (175 degrees C). Lightly grease a 9x5-inch loaf pan.

Combine ground beef, onion, milk, bread crumbs and egg in a large bowl; season with salt and pepper. Transfer into prepared loaf pan.

Mix ketchup, brown sugar, and mustard together in a small bowl until well combined; pour over meatloaf and spread it evenly over the top.

Bake in the preheated oven until no longer pink in the center, about 1 hour.
