What is Horseradish?

Horseradish is a white edible root vegetable of the mustard family. It is widely used as a condiment, a spice, or as a medicine.  (*)

Many people would love to use horseradish to give a kick of spiciness to their food. It is commonly used in sauces or marinades for meat and vegetable dishes.

If you have a fresh horseradish or a creamy horseradish sauce, it is best to have it as a condiment for your steak or prime rib.

How Long Does Horseradish Last?

  • Fresh Horseradish Roots

Your fresh horseradish roots can last from four to six weeks if it is properly kept in the refrigerator. However, the storage period in the fridge may depend on the freshness by the time you buy it.

If you want to keep them in the fridge to maximize the shelf life, make sure you pick the freshest roots in the market.

On the other hand, horseradish roots kept at room temperature or in the pantry will only last for a few days.

  • Frozen Horseradish Roots

Frozen horseradish can last up to 6 months in the freezer. However, if you keep it for a longer time in the freezer, it will gradually lose its quality, aroma, and flavor.

  • Horseradish sauce

An unopened horseradish sauce can last up to 3 to 4 months. Once you have opened a jar, it can stay in the pantry for 4 to 8 weeks.

We advise that you should not dip any food right into the container. That way, you can preserve its quality better and prevent cross-contamination.

Just use a clean spoon to scoop out the amount of horseradish sauce you need for your dish.

  • Homemade horseradish sauce

If you made yourself some horseradish sauce at home, it could last for 3 to 4 weeks if you store it under refrigerated conditions.

  • Frozen horseradish sauce

How Can You Tell if Horseradish Is Bad?

Note that horseradish roots can rot in a few days if you don’t store them in a suitable condition.

Note that these are the characteristics of a fresh and high-quality horseradish root:

  • Firm to touch
  • Clean and free from black spots or mold
  • Has a creamy white flesh when peeled or sliced
  • Has no repulsive smell

Avoid the sprouted ones as they will go bad quickly in the storage.

Once your horseradish gets mushy and soft, that’s already a sign of spoilage.

The roots will also turn dark or brownish when exposed to heat and moisture for a certain amount of time. Do not use that as well.

  • Horseradish Sauce

Whether it is a store-bought or homemade horseradish sauce, you have to check for its appearance, aroma, and flavor to see if it has already gone bad.

If ever your horseradish sauce looks okay, give it a sniff. If it smells off, that should be a sign for you to discard it.
