The Best Way To Store Canned Tomato Sauce To Keep It Fresh - Tasting Table
Briefly

Canned tomato sauce offers a convenient and cost-effective option for weeknight meals, allowing you to enjoy a delicious meal without the pressure of making a sauce from scratch.
To retain flavor and quality after opening, it's best to transfer leftover tomato sauce to a glass or plastic container, as the acidity reacts with metal, altering the taste.
Unopened, canned tomato sauce can last 12 to 18 months in your pantry. After opening, it remains good for five to seven days in the refrigerator.
While the flavor may diminish after the expiration date, unopened canned tomato sauce may still be safe to consume if there are no signs of damage.
