Expiration & Storage Tips
When does fire roasted diced tomatoes expire?
Unopened canned or jarred fire roasted diced tomatoes can last for 12 to 18 months under normal pantry conditions. This is a general guideline, and you should always refer to the printed expiration date on the can/jar. However, once opened, these tomatoes need to be refrigerated in a covered container and should be consumed within 5 to 7 days. If you choose to freeze them, they can last up to 2 months. To use frozen tomatoes, you should defrost them fully in the refrigerator before incorporating into your meal.
How do you tell if fire roasted diced tomatoes is bad?
If the can or jar of fire roasted diced tomatoes is swollen, rusted, or severely dented, it is safer to dispose of the entire pack irrespective of the expiration date. Similarly, if it spurts or foams upon opening, this may point to botulism and should be discarded immediately. In terms of quality, if the color turns from vibrant red to a dull brown, or if there’s a strong, sour smell emanating from the tomatoes once opened, this may indicate that the tomatoes have spoiled.
Tips for storing fire roasted diced tomatoes to extend shelf life
• Store unopened cans/jars in a cool, dry place away from direct heat or light.
• After opening, transfer remaining tomatoes to a covered glass or plastic container before refrigerating.
• Avoid using metal containers for storage as they can react with the acid in the tomatoes, imparting a metallic taste.
• If you need to freeze the tomatoes, consider portioning them into cup or half-cup quantities in freezer bags, which can be laid flat for compact storing.
• Always thaw frozen tomatoes in the refrigerator, not on the counter to maintain food safety.
