A small all-beef meatloaf with milk-soaked breadcrumbs, finely diced onion, and ketchup mixed throughout, without a separate glaze.
All ketchup goes into the mixture; no separate glaze is missing. Shape and thermometer checks govern cooking. Refrigerate cooked portions 3–4 days and reheat to 165°F; ground poultry substitutions require 165°F during initial cooking.
