How long does home-canned tomato sauce last in the pantry?
Home-canned tomato sauce holds 9–12 months in the pantry — write the batch date on the lid, because a jar from two summers back is a guess, not a plan.

Can it sit out?
Unopened, home-canned tomato sauce is shelf-stable. Once opened, treat it as perishable — the FSIS 2-hour rule applies.
Perishable food left at room temperature for more than 2 hours should be thrown out — 1 hour if it’s 90°F or hotter (a picnic, a hot car, a summer kitchen).
How to tell if home-canned tomato sauce has gone bad
- A lid that has lost its dome or gives when pressed
- Dried drips down the glass or seepage under the rim
- Bubbles or cloudiness in a jar that has sat perfectly still
- Anything but cooked tomato in the smell when it opens
When in doubt, throw it out.
Keep the jars in a dark cupboard rather than on a sunny shelf — light bleaches home-canned tomatoes pale long before the year is up.
