It's important to know how long pasta sauce lasts in the refrigerator when you're 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.
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 they're 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 Long Homemade Tomato Sauce Lasts in the Refrigerator
Homemade tomato sauce isn't made with shelf-stable preservatives so it has a shorter life in the refrigerator and generally will last for three to five days.
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 that's 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 can't 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.
How to Store Tomato Sauce
According to FoodSafety.Gov, unopened jars of pasta sauce should be stored at room temperature in a cupboard or pantry. They can be kept for up to 18 months from the date of purchase. As outlined above, once opened, they should be used quickly to avoid spoilage.
Nicole Birmingham, senior vice president of research and development at Rao's Homemade, points out that specific brands may last more or less time than others—but it's important to keep all open sauces at a safe temperature (below 40 degrees ). "How long a jar of pasta sauce will last in the refrigerator may depend on the ingredients used in the sauce, but you should refrigerate any sauce that won't be cooked right away to maintain quality after opening," she says.
If you are using tomato sauce from a can rather than a jar or bottle, remove it from its original packaging (don't just cover the can and put it back in the fridge). "While it is safe to store the food in the can, it will retain better flavor if transferred to a glass or plastic storage container," says Fiest.
How to Store Non-Tomato Based Sauces Like Alfredo
Homemade alfredo sauce lasts the same amount of time once opened but does not freeze and reheat well due to the dairy content. "Although it's not harmful to consume, the cream tends to shatter when you reheat alfredo sauce, which ruins the texture," says Christopher Arturo, chef-instructor at the Institute of Culinary Education. Store-bought alfredo sauce contains cornstarch, which helps the cheese bind properly and prevents separation when reheated.
Can You Freeze Pasta Sauce?
Once opened, jarred pasta can be frozen for longer storage. "You can freeze any unused sauce in an airtight container. Use it within six months for the best quality experience," says Birmingham.
Homemade pasta sauce can also be frozen as long as it doesn't contain cream or cheese. We suggest you freeze it in airtight containers or freezer bags sized for how much pasta sauce you generally need for one meal, rather than storing a large amount of sauce, which will take more space in the freezer, take longer to defrost, and may be more sauce than you need for a meal.
Once opened, it's best to use your jar of pasta sauce in about five to six days. For sauces that contain dairy, like Alfredo or other cream sauces, it's best to stick to three or four days. Unlike bread or other foods, mold is less of a concern — of course, if you leave that jar long enough, mold will certainly grow.
If you've ever wondered how long does pasta sauce last in the fridge, you're not alone. Homemade pasta sauce can be kept in the fridge for three to four days and store-bought sauce can last for up to four days.

If you felt the sauce tasted and smelled good, it was probably fine. You can't wreck a stomach that easily, and notice any symptoms. Keep it refrigerated and it will last two weeks.

First, if the sauce smells off or the taste doesn't seem right, she says you should toss the leftover sauce immediately. Also, if you notice any mold on the inside of the container, it is no longer safe to eat.
It's generally not recommended to use pasta sauce that has been opened and refrigerated for more than 14 days. While some sauces may remain safe to eat beyond this timeframe, their quality and flavor may degrade over time, and there is a higher risk of spoilage.
Store the remaining tomato sauce in your refrigerator. Be sure to put the lid back on the jar as tightly as you can. Make sure to consume it within 5-7 days after opening. Keeping the sauce in the refrigerator will help preserve its freshness and flavor.
They generally last three to four days in the fridge, but you could push it to five days and still live to tell the tale of how delicious it was. Note that pasta dishes sometimes risk getting a little dry because your pasta will soak up extra sauce overnight.
Unless you're a busy diner going through and refilling ketchup bottles every day or two, you should store your ketchup in the fridge. This is because, just like pickles, the flavor and texture declines after you open the bottle or jar and the ketchup is exposed to air.
Rao's recommends that, once opened, sauce be refrigerated and used within 10-12 days. Unused product may also be transferred to a container and frozen for up to 6 months.
For raw ground meats, poultry, seafood and variety meats (liver, tongue, chitterlings, etc.), refrigerate them only 1 to 2 days before either cooking or freezing. Beef, veal, lamb and pork roasts, steaks and chops may be kept 3 to 5 days.
While pasta sauce stays fresh for about five to six days after opening, sauces that contain dairy, such as Alfredo, are best used within three or four days.
Label the containers with the date of preparation or purchase and use them within the recommended time frame. You can also freeze some sauces and dressings, such as pesto, tomato sauce, or vinaigrette, for longer shelf life. Just thaw them in the fridge before using them and stir well to restore their consistency.
Store-bought, fresh pasta is only good for 1 to 3 days, according to Healthline, while homemade fresh pasta is good for 4 to 5 days. However, once cooked, most pasta spoils in about 3 to 5 days. This includes stuffed pastas like tortellini and ravioli, as well as gluten-free, lentil-based, and bean-based pastas.
Barilla recommends storing an opened jar of sauce in the refrigerator for 3-5 days. The remaining sauce may be frozen at any time during the 3-5 days; simply transfer the sauce to a freezer-safe container and it will be good for up to 3 months.
Commercially jarred pasta sauce does not expire. The date on the jar is there to help the grocer rotate his stock. That is all. Absolutely nothing happens to it on that date.
After opening canned goods, store the food in the refrigerator. High-acid canned goods such as tomato products, juice, fruit, pickles, sauerkraut and foods in vinegar-based sauces can be stored five to seven days.
Anything that was air-tight sealed in a bottle, jar, or can can be safely eaten for years after the expiration date. The ingredients may lose quality after a long period of time, but it's almost impossible for them to “grow” anthing that could make you sick.
