Can You Freeze Salad Dressing?

*This post may contain affiliate links. Please see my disclosure to learn more.

Salad dressing generally has a long shelf life, so you are able to keep it in your fridge for quite some time before it begins to spoil.

However, there are some situations that might call for you to extend the shelf life of salad dressing even further, such as buying bulk on special at the store.

So can you freeze salad dressing? Salad dressing can be frozen, but with varied results. You have to have a look at the ingredients in the salad dressing to determine how well the salad dressing will hold up when frozen. For example, salad dressing which contains mayonnaise or any dairy product does not freeze very well. They can be frozen, but the ingredients might separate when thawed and it will be lumpy and curdled. 

Some salad dressings freeze better than others, and some should not be frozen at all. Understanding which salad dressing can be frozen will give you the confidence you need to freeze some at home!

Freezing Salad Dressing: Various Types

There are many different types of salad dressings out there, some with a vinaigrette base, some with a mayonnaise base.

Due to this wide variety, it can be difficult to apply one freezing rule to all types of salad dressing.

Here are some popular types of salad dressings, and whether or not they should be frozen:

Can You Freeze Oil-Based Salad Dressing?

Vinaigrette salad dressings, which are a blend of oil and vinegar, fair okay in the freezer.

You will notice that there will be some separation of the oil and vinegar when it thaws, but you should be able to whisk this together again to have a usable salad dressing.

However, even though you can freeze vinaigrette salad dressings, there isn’t much need to. Depending on the other ingredients included in the vinaigrette, it could have a considerably longer shelf life and freezing really won’t help to extend it that much.

Can You Freeze Dairy-Based Salad Dressing?

Dairy-based salad dressings, such as salad dressings made with cream or cheese, should not be frozen.

This is slightly frustrating as dairy-based salad dressings have a shorter shelf-life than that of vinaigrette dressings, but they do not freeze as well.

When frozen and then thawed, the ingredients separate and it is nearly impossible to get the ingredients to blend back together again. You will be left with a lumpy and curdled salad dressing, which really is not what anyone would want to eat.

Can You Freeze Mayonnaise-Based Salad Dressing?

There are quite a few mayonnaise-based salad dressings, and many home-made dressings include mayonnaise. Mayonnaise, like dairy-based salad dressings, does not freeze well.

When thawed, the ingredients separate, and no matter how hard you try to whisk it back together, the salad dressing will remain clumpy and separated.

Most home-made dressing recipes recommend that you do not freeze the salad dressing, as the results are often less than desirable. You would have wasted more of the dressing by freezing it than if you had left in the fridge and used it until it spoiled.

Ingredients To Consider Before Freezing Salad Dressing

Other than focusing on the base of the salad dressing, whether it be mayonnaise, dairy, or a vinaigrette, you need to consider the other ingredients included in the dressing to determine if it will freeze well or not. 

Ingredients such as green peppers, celery, cloves, and garlic tend to build in flavor and get stronger when frozen. These ingredients might even develop a strong bitter taste once thawed. They will also turn softer and mushy, especially if frozen in larger chunks.

For seasonings such as salt, it tends to lose taste when frozen. Salt also tends to increase the rancidity process in foods when frozen, especially with those that contain fats, and salad dressings generally do combine some fats and salt.

Other spices like onion powder, curry powder, and paprika change their flavor when frozen, and thawed salad dressing might have a very different taste to what you remember it tasting like when fresh.

To avoid the ingredients having these undesired effects on the salad dressing, it is best to add them in after freezing. This would mean freezing the base of the salad dressing and then adding in whatever ingredients and spices you would want afterward.

How To Freeze Salad Dressing

Once you have checked that your salad dressing will be fine to freeze, you will need to know how to freeze it for the best possible results.

Freezing salad dressing is fairly simple, and there is not much that you need to do to prepare the dressing before freezing.

  1. Pour the salad dressing into a freezer-safe plastic container, a deeper cup-like container is better than a wider one.
  2. Seal the container tightly and label it with the date of freezing and with the contents name.

You can also choose to freeze the salad dressing in a plastic freezer bag, and this does help to save space if you are freezing a few bags, as you can lay them flat and stack them one on top of the other to save space.

What To Remember When Freezing Salad Dressing

Liquid expands when it is frozen, and since salad dressings are liquid, they need to be placed in proper freezer-safe containers, and there should be an inch or more left between the top of the salad dressing and the container when it is placed into the freezer.

This allows for the expansion of the salad dressing. If this space is not left, then the liquid could expand and pop the top of the container off, and this could cause a mini-explosion in your freezer.

The same should be done when freezing salad dressing in a plastic freezer bag, you should not fill the salad dressing right to the top, but instead, leave some room for expansion to happen when the salad dressing is frozen.

The trick to this is to also remove as much air as possible from the plastic freezer bag as well, as this could lead to a decrease in quality when frozen.

How Long Can You Freeze Salad Dressing For?

Salad dressing, if stored properly, can be kept in the freezer for up to six months. The salad dressing will be fine to use after this, but the quality will deteriorate quickly and it will not be as tasty, and the consistency will not be the same.

When it is time to use the salad dressing, you should remove the salad dressing from the freezer and leave it to thaw in the fridge overnight or for up to 8 hours. Salad dressing does not have to be reheated or warmed, so you can use it as soon as it has thawed through.

Once thawed in the fridge, you can keep vinaigrette salad dressing for up to a year in the fridge.

Once again, you should not freeze dairy-based or mayonnaise-based dressing, but if you have, you should use it within a week or two, especially if it is a homemade dressing.

How Long Does Homemade Salad Dressing Last?

Homemade salad dressing doesn’t last as long as a storebought salad dressing because it usually doesn’t contain any preservatives. Due to this, it’s best to store homemade salad dressing in the refrigerator and use it within 2 weeks.

There really is no need to freeze salad dressing.

Vinaigrette dressings, which are the best to freeze, don’t really need to be frozen as they have a considerably longer shelf life.
