Store-bought potato salad is a popular go-to for potlucks and picnics, but how long does it last? This amazing side has all the makings of a tasty dish, but like most foods, it will only last for a while.​

Read on to find out how long that potato salad in your fridge will stay fresh.​

How Long Does Store-Bought Potato Salad Last 0

Generally, store-bought potato salad will last five to seven days in the refrigerator.​ Opening a closed container of potato salad will make it last a day or two less, so make sure to keep the lid tightly sealed.​

To be on the safe side, you should check the expiration date printed on the container before you dig in.​

When it comes to home-made potato salads, the numbers slightly decrease.​ Because home-made potato salads typically don’t have preservatives in them like store-bought ones do, they only usually last three to five days in the refrigerator.​

That’s why it’s important only to make as much of the dish as you think you’ll need at the time.​ Plus, if you make too much, you can always freeze the leftover salad for a yummy snack down the road.​

If you want to preserve your potato salad for a longer period of time, you can try storing it in the freezer.​ Be sure to put the salad in an airtight container before you stick it in the freezer, as this will help it last longer.​

Freezing it can guarantee it stays good for up to three months.​ Just remember to let your store-bought or home-made potato salad thaw in the refrigerator for one or two days before you eat it, and you’ll be good to go!

So the next time you’re at a potluck and wonder how long the store-bought potato salad will stay good for, you know the answer.​

Enjoy your summer picnics and family gatherings, knowing that you’ll have a delicious side dish that will almost always taste great.​

Factors to Consider when Storing Potato Salad for Longer Durations

When it comes to storage, there are certain factors you can consider to ensure your potato salads last longer.​

First, make sure to make the salad with cold ingredients, not warm.​ This will help the salad stay cooler for longer.​

Next, ensure you add enough rinsed mayonnaise, mustard, salt, and sugar to the salad, as these ingredients are necessary to preserve the salad over a longer term.​

Then, cover the salad with a lid to prevent air and moisture from entering the container.​

Additionally, avoid adding fruits and vegetables that have a shorter shelf-life when making the salad.​

Lastly, store your potato salad in the coldest part of your refrigerator to maintain its freshness.​

Alternative Options for Storing Potato Salad


If you want to break away from regular refrigeration and look for other options, then freezing your potato salad is probably not the only option.​

For instance, you can use the sous-vide method, which involves using an external water-based device to cook foods in airtight plastic bags for a longer duration.​

This method gives the potato salad a different taste but helps preserve it for a longer period.​ Vacuum sealing is also a great way to make items last longer without compromising on taste.​

With this method, you package the food item in an airtight bag and suck out the air from the bag to seal it.​

Tips and Tricks for Keeping Potato Salad Fresh

In order to maximize the shelf-life and freshness of a potato salad, here are a few tips and tricks to keep in mind.​

For one, add pickles into the mix, as pickles contain natural preservatives that help prolong the freshness of the salad.​

Next, opt for sour cream rather than mayonnaise, as it has a longer shelf-life.​ Then, store pre-made potato salads in the back of the fridge, away from light and heat.​ Additionally, always store potato salads in covered containers.​

Lastly, always discard any leftover ingredients right away and avoid serving a potato salad after it has been left out for more than two hours.​


If you’re looking for a tasty side to your potluck or picnic, store-bought potato salad is definitely the way to go.​

To give your potato salad an even longer shelf-life without compromising on flavor and texture, consider incorporating some of the tips and tricks mentioned above.​

From understanding how long store-bought potato salads last to alternative storage methods, you have all the information necessary to make sure your potato salads always remain fresh.​
