How Long An Open Jar Of Spaghetti Sauce Lasts In The Fridge
Leftover spaghetti sauce in the fridge can become unsafe to eat after sitting for too long, prompting debates about its shelf life and potential for bacteria growth.
While unopened jars can last up to a year beyond their best-by dates in a cool pantry, opened sauce typically lasts five days to two weeks, depending on its ingredients and type.
Tomato-based sauces can stay fresh for five to 10 days, while sauces such as Alfredo will remain edible for a week at maximum. Oil-based sauces can last up to two weeks.
However, these guidelines apply to store-bought sauces that contain preservatives. Homemade or freshly made sauces from the farmer's market can spoil in as little as three days.
Once opened, to prolong spaghetti sauce's shelf life, store it tightly sealed in the fridge in an airtight container to prevent contamination, or freeze it for up to six months.
