Horseradish comes in two different forms: prepared in a bottle or as the whole root. If yours has been sitting in the fridge for a while you may be wondering: does horseradish go bad?
Quick Answer
Yes, horseradish can go bad. Horseradish root will stay fresh for up to 2 weeks outside the fridge. If kept in the fridge, it will last up to 3 months. Horseradish root can also be frozen, keeping it fresh for up to a year. Jarred or canned horseradish sauce will last 6-8 months. Once opened, canned horseradish will last about 5 months.
