Ingredients
  

Meatloaf base
  • 2 lb ground beef Use 80/20 for best moisture.
  • 1 cup breadcrumbs Plain or Italian-style works; ensure the mixture isn’t dry.
  • 2 eggs Helps bind the loaf for clean slices.
  • 0.5 cup milk Soaks breadcrumbs for tenderness.
  • 1 small onion, grated Grate for even distribution.
  • 3 cloves garlic, minced Minced or finely chopped.
  • 2 tbsp Worcestershire sauce Adds savory depth.
  • 1 tsp dried Italian seasoning Seasoning blend for classic flavor.
  • Salt and pepper to taste Season the mixture and adjust to preference.
Ketchup glaze
  • 0.5 cup ketchup For a glossy, tangy top.
  • 2 tbsp brown sugar Balances tang with sweetness.
  • 1 tbsp Worcestershire sauce Keeps the glaze savory.

Equipment

  • 1 cast iron skillet

Method
 

Prep the slow cooker
  1. Line a slow cooker with foil, leaving overhang on the sides to lift the meatloaf out after cooking.
  2. Mix ground beef, breadcrumbs, eggs, milk, onion, garlic, Worcestershire, Italian seasoning, salt, and pepper until combined, with no dry pockets visible.
Shape and cook
  1. Shape the mixture into a loaf and place it in the foil-lined slow cooker, pressing gently so it holds together.
  2. Mix the glaze ingredients and spread half over the top in an even layer.
  3. Cook on Low for 4–5 hours, or High for 2–3 hours, until the internal temperature reaches 160°F, indicated by a thermometer inserted into the center.
  4. Spread the remaining glaze over the top and cook on High for 15 minutes to set the surface, watching it turn glossy.
Rest and slice
  1. Rest for 10 minutes before lifting the meatloaf out using the foil overhang, so the slices hold shape.
  2. Slice and serve warm, with the interior staying moist and tender from the slow, sealed cook.

Notes

Pro tip: grate the onion finely so it blends smoothly and doesn’t create watery pockets; keep the loaf tightly packed for clean slices. Refrigerate leftovers in an airtight container for up to 3–4 days. Freezing: yes—freeze sliced or whole (tightly wrapped) for up to 2–3 months, then thaw in the fridge overnight and reheat until hot. For a lighter option, use 90% lean ground beef and consider adding 1–2 extra tablespoons milk if the mixture feels dry.
