End up making a large batch of delicious pizza sauce? Wondering how long does pizza sauce last in the fridge?

We’ve got all your answers!

Let’s find out!

What’s that One Ingredient that can Make or Break your Pizza?

It’s the pizza sauce!

The beautiful, delicious, garlicky tomato-based sauce adds zing and flavor to your pizza. If pizza is the heart, pizza sauce is the heartbeat; it’s the only ingredient that makes your pizza the BEST PIZZA!

It blends with cheese and other herbs and makes your homemade pizza memorable. However, if your beautiful sauce has gone bad, it can ruin your pizza. And not just the pizza; it can also affect your family’s health.

Generally, authentic pizza sauce is purely based on tomatoes. So, similar to pasta or spaghetti sauce, it gets spoiled over time. We have seen people storing their pizza sauce in the refrigerator for days or weeks and complaining about why their pizza doesn’t taste good.

How Long Does Pizza Sauce Last In The Fridge?

Always remember that not all bad things stink. Pizza sauce remains at its best for four days in the fridge between 35 and 40 degrees Fahrenheit. Storing the pizza sauce for more than 3-5 days is pointless. It will only degrade its quality.

The short answer is, that pizza sauce can last around four days in the fridge. But this is about the store-bought sauce. What about homemade pizza sauce? Will it get spoiled in the fridge? Don’t worry; we will answer all of the questions. Let’s find out!

Pro Tip

One of the best ways to reduce leaks in the fridge is to store opened packages that contain the liquid in a container. Open packages often leak and can even cross-contaminate other items in your fridge. Keeping them in containers reduces this risk and keeps your fridge from smelling.

What Causes Pizza Sauce to Go Bad?

In simple terms, bacteria!

Bacteria exist everywhere in nature. They are in the soil, air, water, and food we eat. When they have nutrients (food), moisture, and favorable temperatures, they proliferate, increasing numbers to the point where some types of bacteria can cause illness. Bacteria grow most rapidly in the range of temperatures between 40 and 140°F.


Bacteria love warmth, especially when it comes from processed tomatoes. If given a favorable environment, they lead to mold. Such foods, if consumed accidentally, can make you sick!

Types of Bacteria in Refrigerated Foods

There are two different families of bacteria: pathogenic bacteria, the kind that causes food-related illness, and spoilage bacteria, the kind of bacteria that causes foods to deteriorate and develop unpleasant odors, tastes, and textures.

Pathogenic bacteria can proliferate in the temperature range between 40 and 140 °F, but they do not generally affect the taste, smell, or appearance of food. In other words, one cannot tell that bacteria is present.

Spoilage bacteria can grow at low temperatures, such as in the refrigerator. Eventually, they cause food to develop or bad tastes and smells. Most people would not choose to eat spoiled food, but they probably would not get sick if they did. It comes down to an issue of quality versus safety:

  • Food left too long on the counter may be dangerous to eat but could look fine.
  • Food that has been stored too long in the refrigerator or freezer may be of lessened quality but most likely would not make anyone sick. 

Come on; no one deserves to fall sick after eating a pizza!

Refrigeration slows bacterial growth. A refrigerator set at 40°F or below will protect most foods.

 So, knowing and understanding the proper food handling and storage is crucial.

Pizza Pun

So my girlfriend left a note on the fridge saying, “Sorry, this isn’t working.”

Then I opened the fridge, and it was still working.

Phew, I thought something bad is going to happen today.

How Long Does Store-Bought Pizza Sauce Last In The Fridge?

Tomato-based foods are among the favorite foods of most people. They got the right amounts of tanginess and just enough sweetness that gives a mouthful of fantastic taste and flavors.

But the sad part about these foods is that they spoil quickly due to the speedy growth of bacteria.

This spoilage becomes even more true when we talk about pizza sauce. Unlike the other sauces, pizza sauce doesn’t last for a very long time, even if you keep it in the refrigerator.

If you leave the pizza sauce on the counter, it will spoil the following day or maybe the evening if you live in colder places.

How Long Does Pizza Sauce Last in the Fridge

But suppose you store pizza sauce in the refrigerator. According to the USDA- Food Safety and Inspection Service, it will last for four days only if the temperature is between 35 to 40 degrees Fahrenheit.

Store-bought sauces are packed with preservatives that make them last for a little longer. For this reason, some folks keep using the opened jar for weeks, which isn’t the right way.

Even if the sauce stays fresh due to refrigeration, it loses its flavor and quality over time. Hence, store-bought pizza sauce should be used quickly once the jar is opened.

Some popular brands claim that their pizza sauce lasts up to 2 weeks. This assumption can be accurate, but we can’t bet on the maintained quality!

How Long Does Homemade Pizza Sauce Last In The Fridge?

We always say homemade pizza is the best. It’s pure, flavorful, rustic, and, of course – made with love!

Nothing can beat homemade pizza sauce except bacteria.

Homemade pizza sauce

The thing is, the homemade sauce doesn’t have any added preservatives or stabilizers. Therefore, they don’t last for weeks like store-bought sauces.

Store your homemade sauce properly in the refrigerator can last for 3-5 days. However, it won’t stay as flavorful as it was on the first day.

If you have tomatoes in season or have your farm produce, you can make a large batch of sauce and freeze it. The frozen tomato pizza sauce can last up to 3-4 months! 

How Can You Tell If Pizza Sauce Is Bad?

This section is essential to this whole post, so read it carefully.

As we have already discussed above, not everything stinks after turning bad. This is especially true in the case of pizza sauce. You might think your sauce is still fresh because it was stored in a fridge, but it gets bad even in the fridge in reality.

Sure, it won’t harbor bacteria due to cold temperatures; it will lose its taste and flavors. It will become bland over time.

If you’ve stocked up your sauce for quite some time, it’s very important to check it before using it on your pizzas. Below are a few ways to check if a pizza sauce has gone bad :


The fastest way to check if the pizza sauce has gone bad is by looking at it. Simply open up your jar and look for the signs of mold. If there are greenish and whitish mold spores on the sauce’s surface and the lid of the container, you must discard it. You won’t see this if your sauce is kept in the fridge.


Open your sauce can and give it a good sniff to see if it’s in the proper condition or not. If you notice any unpleasant and musty odor, then know that your sauce has turned and can’t be used.


This is mainly to check if the sauce is kept in the refrigerator for too long. Just give it a taste and see if it is still flavorful. Generally, such sauces become bland after being kept for longer. So, avoid using a stale sauce and grab a fresh jar if you want your pizza to taste divine!
