How Long Can Salad Dressing Be Left Unrefrigerated?

The short answer to “how long can salad dressing be left unrefrigerated” is two hours. This is in compliance with the two-hour rule as set forth by the USDA.

However, there is a little more to it than that. 

Depending on the ingredients in your salad dressing, you may be able to get away with storing your dressing after a few hours has passed. Or even not storing it at all!

Dressings that are made with dairy or that have fresh ingredients in them, such as dressings that are homemade, will need to be refrigerated right away once used. This is especially true if the dressing you bought was refrigerated upon purchase.

If, however, the bottle of dressing you bought is sealed and was purchased at room temperature, you will only need to refrigerate that dressing once it is open.

Salad dressing doesn’t always have to be refrigerated. If the dressing only contains non-perishable items – like oil and vinegar with salt and pepper, for example – then this kind of salad dressing can be stored at room temperature for a few months at best quality.

Most dressings, however, will require refrigeration of some sort. That is because most dressings contain fresh vegetables (onions, roasted peppers, and the like) or other ingredients (like dairy) that require constant refrigeration, especially once exposed to air.

As previously mentioned, bottled dressings that were purchased at room temperature can stay that way even up to a few months past the best by date printed on the label. This is provided that the bottle of dressing was never opened.

A dressing that was purchased refrigerated, however, must stay that way. These types of dressing typically do not contain many preservatives like those that were sold on the shelves. They are, therefore, more prone to spoilage. 

Does Homemade Salad Dressing Need to Be Refrigerated?

Homemade salad dressing does typically need to be refrigerated, provided that the dressing contains fresh vegetables or dairy. If the dressing only contains vinegar and oil, then refrigeration might not be necessary.

If you really aren’t sure, place your salad dressing in the fridge and use it up within a week of having made it. It is better to err on the side of safety rather than to take the risk of contracting a foodborne illness.

What Salad Dressings Do Not Need Refrigeration?

Salad dressings that do not need refrigeration include those that contain only oil, vinegar, and non-perishable spices. Some people choose to leave store bought dressings out at room temperature after opening because they know they contain preservatives. 

While it is true that dressings bought at room temperature contain preservatives to keep them fresh this way, it is also true that breaking the seal on salad dressing exposes it to air. This can lead to bacteria growth.

As such, it is imperative that you store your dressing in the fridge after opening, even if you purchased a dressing that was sitting on the shelf at the store.

Is Salad Dressing OK If Left Out Overnight?

Unless your salad dressing is a simple dressing that only contains non-perishable ingredients, you may need to throw away any opened or fresh dressings that have sat out overnight. 

As air and moisture reach your dressing, bacteria begin to form and multiply. The longer the dressing sits out, the more dangerous the dressing will be.

The reason that storing the dressing in the fridge is ideal rather than leaving it out, is because the refrigerator slows the process of decay. Therefore, placing your dressings in the refrigerator quickly after opening prevents unhealthy mold and bacteria from growing in your dressing. Refrigeration also allows the dressing to stay useable until the best by date.

Note: As always, be sure not to consume any dressing that has changed in color, taste, texture, or consistency. 

How Do You Store Salad Dressing?

The best way to store your salad dressing will depend on the type of salad dressing you have.

Use the following guidelines for each type of salad dressing: 

  • Homemade Salad Dressing: Store in an airtight container or tightly sealed glass jar for up to one week. Oil and vinegar only salad dressings may be stored in an airtight container at room temperature. 
  • Store-Bought Salad Dressing From Shelf: Store in its original container at room temperature until ready to use. Once you’ve opened the bottle, you’ll need to store this type of dressing in the refrigerator until the best buy date. 
  • Refrigerated Store-Bought Salad Dressing: Store in its original container in the fridge until ready to use. After use, you must immediately place it back in the refrigerator to keep it fresh until its best by date.

How Long Does Salad Dressing Last After Opening?

Salad dressing that has been left open will last about 2 hours before beginning to grow bacteria if it is store-bought and was purchased refrigerated. Any other opened dressings, including those that are homemade, should be refrigerated no more than a few hours after having been used.

All dressings should be thrown out if left overnight, with the exception of those made from simple and non-perishable ingredients, such as oil and vinegar.

Does Oil and Vinegar Dressing Need to Be Refrigerated?

Opened oil and vinegar dressings do not need to be refrigerated if those are the only two ingredients in the dressing. However, if there are any sliced vegetables in the dressing, such as diced peppers or onions, you will need to refrigerate this sort of dressing. 

Does Italian Dressing Need to Be Refrigerated?

Yes, you will need to refrigerate Italian dressing within 2 hours of having opened it. If the bottle was sold at room temperature and is unopened, it will keep at room temperature for up to a few months past its best by date.

Does French Dressing Need to Be Refrigerated?

French dressing does typically need to be refrigerated once exposed to air. That said, French dressings that were bought already refrigerated should be stored in the refrigerator immediately. Keep French dressings of all types in the fridge once opened until the printed best by date.

Does Ranch Dressing Need to Be Refrigerated?

Ranch dressing will certainly need to be refrigerated once opened because of its dairy ingredients. A bottle of ranch that isn’t open and was sold on the shelves won’t need to be refrigerated until opened. But a bottle of ranch that was purchased refrigerated must be kept refrigerated to prevent spoilage.

Does Balsamic Vinegar Dressing Need to Be Refrigerated?

Surprise! Balsamic vinegar does not, technically, have to be refrigerated. Like everything else, refrigeration lessens the amount of bacteria occurring in the vinegar. But generally, balsamic vinegar, on its own, will stay safe at room temperature. 

Note: Once you’ve added other ingredients to balsamic vinegar to make it into a dressing, you’ll need to store the dressing in the fridge for up to a week to preserve it. Bottled balsamic vinegars that contain a wide variety of ingredients should also be stored in the fridge once open.

Does Salad Dressing Need to Be Refrigerated? Most of the Time, Yes!

Most of the time, you will find that your salad dressings need to be refrigerated, especially once open. There are some caveats to this, however. What ingredients were used, for example? These will determine whether or not your salad dressing will remain safe for consumption if left out.

We hope that this helps!

Frequently Asked Questions About how long can salad dressing unrefrigerated

If you have questions that need to be answered about the topic how long can salad dressing unrefrigerated, then this section may help you solve it.

If salad dressing isn’t kept in the fridge, will it spoil?

How long can salad dressing be left out in the open?

Commercial salad dressings are highly acidified, which would prevent or greatly slow bacterial growth. I spoke to a ranch dressing manufacturer, and they advised that if the dressing was out less than 24 hours, it should be fine.

Vinaigrette can be kept outside the refrigerator.

Yes, you should refrigerate it; your homemade dressing is likely more contaminated to begin with and is no different from commercially bottled dressing once it is exposed to the air.

How long can you leave out Italian dressing?

If you want to keep the freshness and preserve the flavor of the dressing after opening the bottle, put it in the refrigerator.Italian dressings typically last for three months without refrigeration; however, those with additional vinegar tend to lose their flavor quicker.

Do clothes that are left outside go bad?

Although some varieties of ranch dressing can be kept unrefrigerated for up to six months, most ranch dressings generally last for about two weeks if stored in the refrigerator, and about one week if left out at room temperature.

What signs of a bad salad dressing should you look for?

One exception here: oil-based dressings, like Italian, naturally separate, so some separation is expected and shouldn’t worry you. What is this? Signs of spoilage are pretty typical: mold, off or rancid smell, noticeable change in texture or taste.

Is oil and vinegar dressing safe to leave out?

The acidity in the vinegar should be sufficient to keep the dressing stable if you use it frequently; however, if you add raw garlic or raw herbal leaves (chopped or otherwise), I would recommend refrigeration because these ingredients have a lower acidity and can spoil the dressing.

How long do oil and vinegar keep when not chilled?

A basic vinaigrette can be stored in a bottle without refrigeration for at least a week or two if it is made with vinegar or another acid, oil, perhaps some mustard, and herbs.

How long does it take a vinaigrette to spoil?

Aside from food safety, we tend to prefer the taste of freshly made dressings, especially when using citrus, yogurt, or garlic, and find that 3-4 days is the sweet spot. We recommend consuming dressings and sauces within 3-4 days to be safe.

Must prepackaged salad dressings be kept chilled?

Information: Keep mayonnaise and salad dressing in the refrigerator for up to two months after opening jars that have not been opened.

Why is it necessary to refrigerate salad dressing?

Salad dressings are oil-in-water emulsions, similar to mayonnaise, so stabilizing them against rancidification is helpful because many varieties of salad dressings are frequently kept after opening for a long time in a refrigerator.

Can salad dressing be left on salad overnight?

The acid in dressing, more specifically the vinegar or citrus juice you used in your dressing, breaks down the cell structure of the leaves, releasing water trapped in the greens. It’s bad because you dressed all of your salad at once.

Does the dressing made with balsamic vinegar and olive oil need to be refrigerated?

Balsamic vinegars can be refrigerated if you use them primarily for salads and prefer them chilled; if you use them for sauces, marinades, and reductions, store them in a cupboard because light and heat are their enemies.

What type of salad dressing doesn’t require refrigeration?

Salad dressings that don’t include ingredients like cream, vegetables, fruit juice, nut oils, yogurt, or mayonnaise can be stored at room temperature, according to The Kitchn.

Does the lemon juice and olive oil dressing require refrigeration?

Refrigerate any dressing that is left over.
