How long does spaghetti sauce last in the refrigerator? Many commercial pasta sauces will last between 5 and 10 days before becoming harmful to eat, depending on the ingredients used in the sauce. Pasta sauce normally lasts a long time if refrigerated soon after opening, due to the acidity of tomatoes and the use of preservatives in commercial sauces.

How Long Does Spaghetti Sauce Last in the Refrigerator?

The ingredients in spaghetti sauce determine how long it will last. Sauces made entirely of vegetables will likely last longer than meat-based sauces. Cream-based sauces will have to be consumed considerably faster. Most tomato spaghetti sauces, on the other hand, should stay in the fridge for at least 5 days, if not longer.

Your estimate should be based on the ingredient with the shortest shelf life. A basic tomato sauce with simply veggies in it, for example, should last at least 5 days, but if the sauce incorporates shrimp or chicken, you may want to eat it up sooner.

Keep the sauce cool to extend its shelf life, so put it in the fridge as soon as possible. If it’s in a can, you might want to decant it into another container. Tomatoes may react with the can and develop an unusual flavour, even if they are still edible.

As soon as you’ve opened the sauce, transfer it to a clean, airtight container, cover it, and store it in the refrigerator. Leaving the sauce at room temperature can cause it to spoil more faster, and it might become harmful to eat in as little as a few days.

If the room temperature is above 90 degrees, the sauce must be refrigerated within 2 hours.

What Ingredients Cause Spaghetti Sauce to Go Bad Faster?

Sauces with meat, cream, or cheese will not keep as long as sauces with just vegetables. If the sauce contains any of these ingredients, it should be fine to consume after a couple of days in the fridge, but try to eat it within three days.

Reheating and cooling the sauce repeatedly can foster the growth of harmful germs. Instead, only heat what you need at a time and keep the rest refrigerated to prevent bacteria from forming.

How Long Can You Keep Homemade Spaghetti Sauce?

It’s crucial to keep in mind that homemade spaghetti sauce often lacks the preservatives present in store-bought spaghetti sauce, and it won’t keep as long in the fridge. If you’ve produced your own sauce, attempt to consume it within three to five days.

Although tomatoes are acidic and store well, they are not normally safe to keep in the fridge for longer than this. Put homemade sauce in an airtight container and chill it as quickly as possible, like with commercial sauce, to avoid reheating and cooling.

Is Spaghetti Sauce Freezable?

Most spaghetti sauces store well, so if you have a jar or can that you won’t finish in time, decant it into an airtight container and freeze it. Sauces containing dairy, on the other hand, may not freeze well since the texture of the dairy will be ruined in the freezer.

Both homemade and commercial spaghetti sauce can be frozen for months with no problems, so this is a fantastic method to cut down on waste if you open sauces frequently but rarely use them all. Simply decant the sauce you won’t be using into a container and store it in the freezer with a lid.

Place the frozen spaghetti sauce in the refrigerator overnight to thaw. If you need it to defrost faster, submerge it in cold water and change the water every half hour until the sauce is defrosted. You can also thaw it in the microwave if the container is microwave safe.

How Do You Know If Your Spaghetti Sauce Is Bad?

A weird odour, flakes of mildew on the surface, or an unusual flavour are all indicators that spaghetti sauce has gone bad. Be aware that a sauce that has split badly may be dangerous to eat.

If you have any doubts about your spaghetti sauce, the best thing you can do is scrutinise it thoroughly. Warm it up a little and take a whiff of it. Is there a rotten or sour stench to it that you wouldn’t expect from tomatoes? If that’s the case, it’s no longer safe to eat.

Similarly, if you detect mould specks floating on the top or on the container’s edge, the sauce is no longer safe to eat. Even if the mould appears to be contained to a single area, it must be discarded. The spores will have infiltrated the remainder of the sauce.


The shelf life of spaghetti sauce in the fridge varies depending on the components, but in general, spaghetti sauce keeps well in the fridge and can last up to ten days.

As the date approaches, make sure you inspect it well before eating it to see whether it has gone bad. Any unusual odour, flavour, or visual appearance should serve as a warning not to consume the sauce.
