Can salad dressing be frozen?

Salad dressing tends to have a long shelf life, so you can keep it in your fridge for quite some time before it starts to go bad.

However, there are some situations that may require you to extend the life of your salad dressing even further, such as buying it in bulk on sale at the store.

So can salad dressing be frozen?

Salad dressing can be frozen, but with mixed results. You have to take a look at the salad dressing ingredients to determine how well the salad dressing will hold up when frozen. For example, salad dressings that contain mayonnaise or any dairy product do not freeze very well. They can be frozen, but the ingredients may separate when thawed, leaving it lumpy and curdled. 

Some salad dressings freeze better than others, and some should not be frozen at all. Understanding which salad dressings 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, some vinaigrette-based and some mayonnaise-based.

Because of this wide variety, it can be difficult to apply a freeze rule to all types of salad dressing.

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

Can oil based salad dressing be frozen?

Vinegar-based salad dressings, which are a mixture of oil and vinegar, can be safely frozen.

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

However, while you can freeze vinaigrette salad dressings, it’s not really necessary. Depending on the other ingredients included in the vinaigrette, it could have a considerably longer shelf life and freezing won’t really help extend it very much.

Can dairy-based salad dressing be frozen?

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

This is a bit frustrating, as dairy-based salad dressings have a shorter shelf life than vinaigrette dressings, but they don’t freeze as well.

When frozen and thawed, the ingredients separate and it’s almost impossible to get them to mix again. You’ll be left with a lumpy, curdled salad dressing, which really isn’t what anyone would want to eat.

Can mayonnaise-based salad dressing be frozen?

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

When it thaws, the ingredients separate, and no matter how hard you try to re-whisk it, the salad dressing will be caked and separated.

Most homemade dressing recipes recommend against freezing the salad dressing , as the results are often less than desirable. You’ll have wasted more dressing freezing it than if you left it in the fridge and used it until it went bad.

Ingredients to Consider Before Freezing Salad Dressing

In addition to focusing on the base of the salad dressing, whether it’s mayonnaise, dairy, or a vinaigrette, you need to consider the other ingredients included in the dressing to determine whether or not it will freeze well.

Ingredients like green bell pepper, celery, cloves, and garlic tend to build up flavor and get stronger when frozen. These ingredients can even develop a strong bitter taste once thawed. They will also become softer and doughier, especially if frozen in large chunks.

In the case of seasonings, such as salt, it tends to lose flavor when frozen. Salt also tends to increase the rancidity process of foods when frozen, especially those that contain fat, and salad dressings often combine some fat and salt.

Other spices, such as onion powder, curry powder, and paprika, change flavor when frozen, and thawed salad dressing can taste very different than you remember it when fresh.

To prevent ingredients from having these unwanted effects on your salad dressing, it’s best to add them after freezing. This would mean freezing the base of the salad dressing, then adding whatever ingredients and spices you want.

How to freeze salad dressing

Once you’ve verified that your salad dressing will be okay to freeze, you’ll need to know how to freeze it for the best possible results.

Freezing salad dressing is pretty straightforward, and there isn’t much to do to prepare the dressing before freezing it.

1. Pour salad dressing into freezer-safe plastic container; a deeper container, such as a glass, is better than a wider one.
2. Close the container well and label it with the freezing date and the name of the content.

You can also choose to freeze the salad dressing in a plastic freezer bag, and this helps save space if you’re freezing a few bags, since you can lay them flat and stack them on top of each other to save space.

Things to Remember When Freezing Salad Dressing

Liquids expand when frozen, and because salad dressings are liquid, they should be placed in freezer-safe containers , with an inch or more remaining between the top of the salad dressing and the container when placed in the freezer. .

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

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

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

How long can salad dressing be frozen?

Salad dressing, if stored properly, can keep in the freezer for up to six months . The salad dressing can be used later, but the quality will quickly deteriorate and it won’t be as flavorful, and the consistency won’t be the same.

When it’s time to use the salad dressing, you should take it out of the freezer and let it thaw in the fridge overnight, or up to 8 hours. The salad dressing doesn’t have to be reheated or heated, so you can use it as soon as it’s thawed.

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

Again, you shouldn’t freeze dairy or mayonnaise-based dressing, but if you do, you should use it within a week or two, especially if it’s a homemade dressing.

How long does homemade salad dressing last?

Homemade salad dressing doesn’t last as long as store-bought because it usually doesn’t contain preservatives. Therefore, it is better to store homemade salad dressing in the refrigerator and use it within two weeks.
