Its important to know how long pasta sauce lasts in the refrigerator when youre reaching for an already-open jar. You might be using it for a quick weeknight pasta dinner or adding some to enhance the flavor of a stew, because there are so many ways to use tomato-based sauces. Ahead, food safety experts weigh in on how to know if pasta sauce is no longer tasty or safe to eat—and offer storage tips for both refrigerating and freezing your leftovers.
You will need four pint-sized jars with sealable lids for canning; the lids and jars need to be sterilized, which can be done by boiling in a large pot for 10 minutes. Let them dry before filling. Canned tomato sauce will remain good for up to a year, stored in a cool, dark place.
How Long Does Opened Pasta Sauce Last in the Refrigerator?
Most jarred tomato-based sauces have a shelf life of about one year. However, once theyre opened, they should be used quickly. “After opening a high-acid canned food, like a tomato sauce, it can be stored safely in the refrigerator for five to seven days before being used,” says Shelley Feist, executive director of the Partnership for Food Safety Education. Check the sauce before using, even in this timeframe, to make sure it has not spoiled.
Other jarred sauces, like Alfredo and cream sauces, should be used in three to four days after opening.
How to Tell When Pasta Sauce Has Spoiled
There are several telltale signs that tomato sauce has spoiled: It will look moldy, smell bad, or taste off. However, pasta sauce thats old—but not noticeably rotten—can still cause food poisoning, and aside from mold, there are no other visible signs that tomato sauce is past its peak. “You cant see, smell, or taste the bacteria that can cause a foodborne illness,” says Feist. She recommends always reheating sauce to 145 degrees Fahrenheit before using it to kill any bacteria that is a result of mild spoilage. Also, if you notice any unusual smell, particularly a sour or rotten smell, this is a sign your pasta sauce has spoiled and should be tossed out. If the sauce has been opened for less than five days, taste it before using; if it tastes off or sour in any way, it should be thrown out.
