Some people may not know how long does tartar sauce lasts? This article will answer this question for you.

What is Tartar Sauce?

Tartar sauce is a mayonnaise-based condiment typically served with seafood.

Common ingredients in tartar sauce include mayonnaise, pickles, capers, horseradish, and chives.

Some dishes that are typically served with tartar sauce include fried fish sandwiches and shrimp cocktail.

Tartar sauce might also be used as a condiment for salads or hamburgers, and hot dogs.

Tartar sauce is sometimes referred to by its French name (aioli).

A few variations of this type of sauce have been developed, such as garlic mayonnaise or curry-flavored mayo.

Tarter sauce originated in France and was initially served with fish from the sea during Tudor times.

Nowadays, tartar sauce is served with many types of seafood as well as other dishes.

Tartar Sauce has a tangy and creamy taste, but various spices can change their preference from slightly sweet to spicy.

How to Store Tartar Sauce?

Is there a more quintessential condiment than tartar sauce? Your fish and chips wouldn’t be complete without it, and your fish tacos won’t live up to expectations without that creamy sauce.

If you’re like most people who buy tartar sauce in a jar or bottle, it’s probably sitting on the shelf of your refrigerator door just waiting for its subsequent use.

But after reading this blog post, you may want to consider moving it elsewhere.

One big mistake many people make is storing their tartar sauce right on the top shelves of their fridge – usually near other condiments such as ketchup or hot sauces, which can easily contaminate it with bacteria.

This could spell disaster for your next batch of tartar sauce, so make sure you store it in a cool and dark place.

A great way to do this is by storing the jar or bottle on its side, as we recommend with mayonnaise – near the bottom shelves away from other condiments which can contaminate it.

You can also freeze the tartar sauce to maximize its shelf life – pour it into an ice cube tray and put it in the freezer.

Once frozen, transfer your cubes to a sealable plastic bag or container that will fit them all side-by-side (think of using those individual containers for fruit when grocery shopping).

How Long Does Tartar Sauce Last?

It is not hard to answer the question of how long does tartar sauce lasts.

As a condiment, it should be kept in your refrigerator for up to 6 months after opening without any spoilage issues arising.

However, if you are using this as an ingredient (such as on fish or egg salad), follow the instructions and keep refrigerated until use-by date.

For unopened jars, you can store them in your pantry for up to 18 months.

If you are a fan of homemade tartar sauce, the best thing to do is make it in small batches and store them in the refrigerator.

The homemade version lasts up to two weeks and can be refrigerated but not frozen.

How to Tell if Tartar Sauce is Bad?

There are a few signs that this may be happening.

One easy way to see what’s going on with your jar is to open the jar and take a smell.

If it smells like vinegar, then you know that something is wrong with your sauce.

Another way to test if tartar sauce has gone bad is by looking at its color inside the jar.

Tartar should be creamy white or yellowish–not pink or orange.

When checking for this sign, look for mold growth because those colors indicate that there’s not enough acidity in the mixture, which can cause spoilage issues.

Finally, when testing whether or not tartar sauce is spoiled, one should also consider how thick it is upon opening the jar and dipping a spoon into it (if applicable).

The thickness of tartar sauce will change over time depending on the acidity levels, but in general, you should expect it to be thick and creamy – not watery or “mushy” at all.

If one of these signs is present, then tartar sauce is bad and should be discarded.


In conclusion, tartar sauce is a great condiment to accompany any meal.

It tastes delicious with fish, shellfish, and fries.

If you do not use up the jar of tartar sauce before it expires, you can seal and refrigerate it.

This process will extend its life by six months.

Ensure you keep an eye on any unused portions as they’ll only stay fresh for a limited time.
