Can You Freeze Mayonnaise To Extend Its Shelf Life? Shelf Life, Pros, And Cons

Should you freeze that jar of mayonnaise?

Mayonnaise is one of the food items you’d most likely see in every refrigerator. Some people even have jars of mayo stashed in the freezer for long-term purposes.

Refrigerating opened mayo is one of the best ways to keep it fresh for salads, sandwiches, cakes, and deviled eggs. But, freezing mayonnaise is not always a good idea.

Continue reading to see why you probably shouldn’t freeze your mayonnaise.

What is mayonnaise?

Simply put, mayonnaise or mayo is an emulsion of oil, egg yolk, lemon juice (which could be vinegar or mayo), and other additives.

An emulsion is a mixture of two liquids that won’t mix naturally. But in mayo, the egg yolk is the emulsifier that makes everything bind into a creamy sauce.

Mayonnaise is a good substitute for salad dressing. Also, it works perfectly as a binder for cake or bread, sauce thickener, sandwich spread, and mayo makes a very good cheese sandwich.

Can you freeze mayonnaise?

Yes, you can freeze mayonnaise to preserve it. However, freezing your jar of mayo is not always advisable. Mayonnaise is an emulsion that looks good until it begins to defrost.

As mayonnaise thaws, the individual ingredients separate and leave it looking less appealing. The oil separates and other liquid ingredients float to the top, leaving the egg yolk at the bottom of the jar.

Additionally, the degree of separation of the ingredients in mayonnaise varies with how it was prepared. Homemade mayo breaks down worse than store-bought mayo.

However, this unpalatable mayo does not affect your health. It only affects the ability of the mayo to make your meals turn out nice.

Can you freeze mayonnaise on a sandwich?

While freezing sandwiches could be a blessing, freezing sandwiches with mayo on them is not a good idea.

Mayonnaise is creamy and the cream will leave your bread wet and soggy. After freezing, the mayo separates as it thaws and leaves you with an oily sandwich.

The best way to preserve your sandwich is to freeze it without the cream. Apply the cream when you’re ready to eat it or store it in a refrigerator instead.

Can you freeze mayonnaise-based sauces?

Yes, you can but you shouldn’t.

The frozen mayo-based sauce will separate as it thaws and leaves you with a funny sauce. And, yes, even after mixing all the ingredients, the sauce (although still edible) will be unappetizing.

Can you freeze mayonnaise-based dips?

You may freeze mayonnaise-based dip but after thawing, you’ll be left with a crumbly or watery dip.

Mayonnaise is an emulsion that will break down into an oily liquid and egg yolk base after defrosting. The best way to preserve your mayo-based dip is to put it in a refrigerator.

Can you freeze mayonnaise in a casserole?

Frozen casserole with mayo in it will come out grainy after it thaws.

If you already have frozen casserole with mayonnaise in it, allow it to thaw and reheat it at the same temperature you cooked it.

Also, you can add cornstarch or flour (as a stabilizer) to the dish before you freeze it. However, the best way to preserve your casserole is to freeze it without mayonnaise. Thaw and add mayo only when you’re ready to eat it.

Can you freeze mayonnaise cake?

Yes, you can freeze mayonnaise cake.

Unlike freezing other mayo-based foods, a mayonnaise cake will not separate even after it thaws. Mayonnaise in a cake replaces egg and oil just like in a regular cake.

All you need to do is allow the cake to cool and wrap it in plastic wrap and foil before freezing it. Mayonnaise cake can last up to three months in a freezer as a traditional cake would.

Can you freeze mayonnaise-based salads?

Freezing mayo-based salads is not a good idea.

The ingredients in mayonnaise do not bind well during freezing and neither do they keep salad condiments together. So, when the salad thaws, it is less appetizing and has a not-so-good taste.

For salads like mayo-based chicken salad, freezing will reduce the quality.

Mayo-based potato salad will become contaminated with bacteria while it thaws in the kitchen. This is because potato salad doesn’t fare well with freezing due to the temperature-sensitive ingredients it contains.

How long should you freeze mayonnaise?

You should not freeze your jars of mayonnaise for too long.

Store-bought mayo (unopened) can last up to four months out of the refrigerator. Homemade mayo, on the other hand, will last only eight hours outside the refrigerator.

Store-bought mayo (opened) will last up to two months if you refrigerate it. Refrigerated homemade mayo should be consumed within six days.

Can you eat mayonnaise after thawing?

Thawed mayo is edible, but will not be as palatable as it used to be. It will also not mix or bind well with other ingredients.

How do you know your mayo has gone off?

Mayonnaise has gone bad when you notice mold growth on the surface or around the neck of the jar. Also, a brownish-yellow discoloration, acidic smell, and funny taste are signs that you should trash that jar of mayo already.

In addition, check the body of the mayonnaise jar for the production and best-by date to know if your mayo has gone off.

Can you freeze tuna salad with mayo?

You shouldn’t freeze tuna salad with mayo on it because mayo is an emulsion that will separate when it thaws. It doesn’t mix with the rest of the meal and leaves you with an unappealing dish.


Mayonnaise is a common ingredient and a very useful one at that. With good intentions, almost every family has at least a jar of mayo in the refrigerator or freezer for future use. However, these good intentions result in a less appetizing mayonnaise.

You should also know that thawed mayo is still edible and won’t affect your health. But you shouldn’t expect it to give you an appetizing meal either.

The best way to store mayonnaise is to keep an unopened jar in the pantry. Keep the opened jar in the refrigerator and consume it within one to two months.
