Throughout the year, pasta and its various sauces regularly make an appearance on our dining table.

This means that there are often leftovers after a meal or two, with the leftover pasta needing some sort of use.

Whether it’s for a quick snack later or an easy lunch the next day, you may have some leftover pasta sauce laying around.

We want to know how long your pasta sauce lasts in the fridge so we can help save time and avoid wasting food.

Check out this article to find out how long pasta sauce keeps in the fridge, as well as what factors affect its shelf life. 

How long does pasta sauce last in the fridge?

For the most part,  the best way to preserve your pasta sauce is to eat it soon after making it.

Once you open the jar, your sauce will begin to degrade (and smell bad).

However, if it’s sealed properly, you can keep it in the fridge for up to six months.

The longer your sauce sits in the fridge, the more likely mold will grow.

If you do plan on keeping your pasta sauce in the fridge for several days, make sure to check it frequently for any signs of spoilage.

It’s also important to keep the lid on tightly in order to prevent air from getting into the container and causing the mold to develop.

How long will pasta sauce last in the fridge?

There isn’t really a set answer to how long pasta sauce will keep in the fridge.

Each brand has its own expiration date based on how long they take to produce.

Some sauces are made fresh daily, while others are factory-made and stored in large batches.

In general, sauces made at home tend to keep longer than those that come from a factory.

A homemade sauce usually contains less preservatives and additives.

As a result, it won’t deteriorate as quickly.

If you’re not sure whether your sauce is homemade or not, look for a label with “homemade” listed somewhere near the ingredients list.

Also, ask yourself why would someone buy something that is going to expire within weeks of being opened?

When purchasing pasta sauce, remember to check the expiration date.

You should also check how thick it is.

Thin sauces will go bad faster due to exposure to light.

Thick sauces are harder to see and might still taste good even though they’ve been sitting in the fridge for a few years.

How long can pasta sauce stay in the fridge?

Most people don’t like to throw away perfectly good food just because it’s overripe.

That’s where the “use by” dates come in.

These dates indicate how long the product should be kept before using it.

For example, a jar of pasta sauce could have a “use by” date of one month, meaning you’re allowed to use it until the following month.

However, these dates aren’t always accurate.

They were created to allow manufacturers to gauge when products were nearing their end of their shelf lives, but they didn’t account for other variables.

For example, temperature changes, humidity, and packaging material are all factors that affect how long your pasta sauce lasts.

Refrigeration is one of the best ways to prolong the shelf life of your sauce.

If you decide to put the sauce back in the fridge after opening, store it in a cool spot and leave the lid off.

If possible, rotate the sauce once every week.
