How long does jarred horseradish last in the fridge?
Prepared horseradish keeps 3–4 months once opened and 12 months unopened, cold either way — the heat fades well before the jar does, so buy the small size.

Can it sit out?
Jarred horseradish is perishable — the FSIS 2-hour rule applies.
Perishable food left at room temperature for more than 2 hours should be thrown out — 1 hour if it’s 90°F or hotter (a picnic, a hot car, a summer kitchen).
How to tell if jarred horseradish has gone bad
- No sting at all when you lean over the open jar
- Shreds browning off instead of staying bright white
- A dried crust and mold at the rim
- A watery layer that stirs back in cloudy
When in doubt, throw it out.
Stir it into cream or sour cream at the last minute — the heat blows off within minutes of standing, and faster in a hot pan.
