Preheat Oven : Preheat oven to 375°F (190°C). Line a baking sheet with parchment paper or lightly grease.
Prepare Meat Mixture : In a large bowl, combine ground beef, breadcrumbs, egg, onion, garlic, milk, ketchup, Worcestershire sauce, salt, pepper, and Italian seasoning. Mix until just combined (don’t overwork).
Shape the Mummy : Transfer mixture to baking sheet and shape into an oval loaf resembling a mummy body. Smooth the top.
Bake Meatloaf : Bake uncovered for 45–50 minutes, until internal temperature reaches 160°F (71°C).
Add Ketchup Glaze : Remove from oven, brush top with a thin layer of ketchup for flavor and color.
Wrap with String Cheese : Peel string cheese into thin strips and lay across the meatloaf in crisscross fashion to look like mummy bandages.
Final Bake : Return meatloaf to oven for 5–10 minutes, just until cheese softens (don’t let it fully melt).
Add Eye : Place olive slices on the “face” area, securing them with a dab of mustard or ketchup.
Rest and Serve : Allow meatloaf to rest for 5 minutes before slicing. Serve warm.
