What Exactly Is Horseradish?

Horseradish is a delicious Brassicaceae family root vegetable. It is linked to wasabi, broccoli, mustard, radish, cabbage, and other vegetables.

Horseradish is well-known for its characteristic pungent flavor and has been used for food and medicine for generations. Horseradish is commonly used as a marinade and condiment in the culinary world. It’s a terrific side dish for steak and substantial roast meat.

Depending on availability or choice, you can obtain fresh horseradish roots, prepared horseradish, and horseradish sauce. It’s important to note that prepared horseradish and horseradish sauce is not the same thing.

Horseradish is prepared by combining the root, vinegar, and salt. On the other hand, Horseradish sauce is mixed with cream or mayonnaise, resulting in a softer, creamier flavor.

Does Horseradish Go Bad?

Is it true that horseradish goes bad? This question has a straightforward answer: “yes.” Horseradish deteriorates with time. Horseradish, like all other plants, does not last forever.

It begins to alter in look, fragrance, and flavor with time.

On the other hand, how you keep your horseradish impacts how long it will stay fresh.

Convenient storing in damp pantries may greatly increase its shelf life. Furthermore, ensuring that the horseradish does not frequently come into touch with water provides you a longer usage duration.

How Long Will Horseradish Last?

Horseradish Extract

Horseradish root may be stored in the refrigerator for 1 to 2 months if properly refrigerated. However, once sliced or grated, the taste and spice begin to fade quickly. As a result, it is preferable to consume the food within a few days.

Sauce with Horseradish

A “best by” or “best-before” date is printed on store-bought prepared horseradish and horseradish sauce packaging. As long as optimal storage conditions are fulfilled, the items will retain their quality at least until expiration and probably beyond.

Try to complete these condiments within a couple of months of opening. Over time, the flavor and spice begin to deteriorate. Although it is still edible, aged horseradish sauce may not have the same kick as new horseradish sauce.

Homemade prepared horseradish can be stored in the refrigerator for up to 2 weeks.

Horseradish root (whole)1 to 2 weeks1 to 2 months
Horseradish root (cut)1 week
Prepared horseradish (homemade)2 to 3 weeks
Horseradish sauce and prepared horseradish (unopened)1 to 2 years, or best by + 1 to 3 months
Horseradish sauce (opened)1 to 3 months

The dates shown above are just estimations. The actual shelf life is determined by the preparation technique and storage conditions.

How Long Will Horseradish Keep Outside?

Horseradish sauce in a jar and horseradish root may both be stored at room temperature. It’s best to keep opened horseradish sauce in the fridge.

Horseradish root has the finest flavor when consumed within two weeks of purchase. Horseradish root will lose taste and scent if not used within two weeks, although it is still safe to consume.

On the other hand, Horseradish sauce may be stored at room temperature for up to 8 months. It is not advised to leave unsealed jars of horseradish sauce outside the refrigerator.

How Long Does Horseradish Keep in the Refrigerator?

Horseradish root can be stored in the refrigerator for up to two months. Unlike other veggies, it will not decay. Rather, it will lose its taste and fragrance. It’s still safe to consume after 2-3 months, but it won’t taste as fresh and may even taste harsh.

When unsealed, prepared horseradish sauce does not normally keep any extra freshness when refrigerated. It has a shelf life of up to 8 months.

If you open a jar of prepared horseradish sauce, it is preferable to store it in the refrigerator. This will keep the food fresh for up to 5 months.

How Long Can Horseradish Be Stored in the Freezer?

Raw horseradish root can keep in the freezer for up to a year. If you don’t use horseradish very often, freezing it is an excellent method to keep it fresh and bite-sized.

It’s a different story with prepared horseradish sauce. It is not suggested to freeze prepared sauces since they lose flavor fast when exposed to excessively cold temperatures.

If you’re going to freeze horseradish, store it correctly to preserve it as fresh as possible.

When horseradish loses its flavor, it turns bitter and is no longer suitable for sauces.

Sauces should be discarded every six months. As a result, if you don’t use horseradish very often, it’s crucial to understand how long the various forms endure.

How to Tell If Your Horseradish Is Bad

Following appropriate storage practices allows your horseradish to stay fresh for a longer amount of time. However, horseradish does not last forever and will expire after a while. Here are several indicators that your root or sauce has gone bad:

Mushy And Softening

When the horseradish root becomes limp, wilted, and mushy, it’s time to get rid of it. To the touch, a healthy root should be strong and sturdy. If a root is not hard enough, it has already gone rotten.

However, the softness’s strength decides whether you can use the horseradish. Even if it’s a little mushy, you can still eat it. However, if the root is unusually soft to the touch, we suggest you not eat it since it may be harmful to your health.

Notable Color Alteration

When horseradish begins to deteriorate, its color shifts to black or brown; you may notice a minor color shift, indicating that the damage is minor. However, if the color change is significant, you may be obliged to dispose of the roots.

Horrible Smell

You could notice a strange odor coming from your cupboard or fridge, where you keep your horseradish. Mostly when it comes to sauce, there is a change in fragrance. We usually recommend removing horseradish sauce when it loses its fresh odor and develops an unpleasant odor.

Bitter Aftertaste

When horseradish gets bad, it loses its fresh and sweet flavor and becomes bitter. It can even be too bitter to eat. Furthermore, the taste may become excessively unpleasant, rendering it unpalatable. As a result, anytime you believe your horseradish is stale, you should taste it.

Mold Development

Mold formation on horseradish stored in the cupboard or refrigerator indicates deterioration. While some molds are innocuous, some are severely harmful to the body. When mold appears on your root or sauce, you should remove it as soon as possible.

What happens if you consume Old Horseradish?

Horseradish has a high nutritional value for the body. Aside from being a fantastic spice, it is most recognized for causing a burning feeling in your sinuses, throat, and mouth. As a result, the feeling is beneficial in the treatment of colds.

Furthermore, the roots contain potent antimicrobial qualities that benefit your health. On the other hand, consuming outdated horseradish may have negative consequences on your body. Because the root loses power as it ages, it may have less nutritious value.

The following are some of the side effects of swallowing stale horseradish:

Possibility of Food Poisoning

As previously stated, mold begins to form on horseradish as it ages and expires. Mold grows not just on the surface of the horseradish but also deep within it. As a result, scraping the apparent molds does not eradicate them. Consuming molded horseradish increases the chances of getting food poisoning.

Complications of the Stomach

Consuming outdated horseradish may jeopardize your stomach health, stability, and overall body wellness. As previously said, the roots become bitter and mushy as the horseradish reaches the end of its life. As a result, the mushy and unpleasant-tasting horseradish may induce gastrointestinal distress.

We recommend that you always discard outdated horseradish and avoid eating it if you observe any symptoms of deterioration.

Horseradish Storage Instructions

Horseradish Root Storage

Begin with fresh horseradish roots. They are stored in the same manner as many other vegetables, such as kale. That means you should keep them wrapped or in a bag in the fridge, preferably in the vegetable drawer.

Make sure there are holes in the bag or wrap to allow ventilation. For the same reason, you should pack them loosely. If you keep the roots at ambient temperature, they will decay considerably faster than if you keep them refrigerated. Refrigeration isn’t necessary if you expect to utilize all of them within a few days.

Horseradish Sauce Storage

When it comes to commercially bottled prepared horseradish, it should be stored in the same way that other sauces and condiments, such as mustard or mayonnaise, are. As long as it is unopened, you should keep it in a cold, dry place, away from sunshine and heat sources. The pantry is the greatest option, but a kitchen cupboard would suffice.

After opening the bottle, keep the horseradish sauce well wrapped and refrigerated.

If you intend to retain the sauce for an extended amount of time, store it upside down. This way, it will stay fresher for longer.

When scooping prepared horseradish from the bottle, use clean utensils and never double dip, as you would with any other condiment. This reduces the possibility of microbial infection, leading to the product spoiling prematurely.

Can Horseradish Be Frozen? How?

Freezing horseradish is an excellent technique to keep it fresh for longer. What’s the best part? It is not necessary to defrost it for a day before utilizing it.

  • The first step in freezing horseradish root is to grate it. Grating it into small pieces, such as how much you need for a dish, is an option. Smaller quantities will ensure that the gratings stay as fresh as possible.
  • Airtight Container: If you wish to freeze horseradish gratings, place them in an airtight container or bag. This will keep the root as fresh as possible for as long as possible. Frost burn on horseradish may be avoided by storing it in airtight containers.
  • Baking Sheet: You may line a baking sheet with plastic wrap and spoon the grated horseradish onto it. Once the gratings have frozen in spoonfuls, take them off and store them in freezer bags.

How Should You Thaw Horseradish?

There is no precise method for thawing horseradish.

Whole horseradish: It will be tough to grate right from the freezer if you defrost a whole horseradish. Allow it to sit on the counter for an hour or two before using.

Horseradish, grated: Grated horseradish can be used straight from the freezer.


Understanding the safety of the spices we use in cooking is critical. Because of its therapeutic benefits, horseradish is particularly popular among vegetarians.

To provide the greatest service, it is critical to understand how to increase the shelf life of this spice. You should also have guidelines for spotting outdated horseradish on hand.
