Preheat your oven to 350 degrees. Prepare a loaf pan (9x5) with nonstick cooking spray and set aside.
In a large mixing bowl add ground beef, finely minced onion, eggs, bread crumbs, Worcestershire sauce, pepper, seasoning salt, garlic powder, and 1/2 cup of ketchup. Gently mix with hands and then add to loaf pan.
