Safe Alternative #2: Freezing
If you prefer to preserve the complete, ready-to-cook meatloaf, freezing is the safest and easiest option.
-
Bake, then freeze: Cool the fully baked meatloaf completely, then wrap it tightly in a double layer of plastic wrap and heavy-duty foil before freezing.
-
Slice, then freeze: Freeze individual slices on a baking sheet before transferring to a freezer bag.
-
Freeze raw for later baking: Shape the raw mixture into a loaf, freeze on a tray until solid, then wrap it tightly.
🚫 Important: Why You Shouldn’t Can Traditional Meatloaf
The density of a typical meatloaf (with its eggs, breadcrumbs, and sometimes tomato sauce) does not allow heat to penetrate to the center of the jar evenly, even with a pressure canner. This means harmful bacteria can survive, creating a serious risk of food poisoning.
