How long does radicchio last in the fridge?
Radicchio keeps 2–3 weeks in the fridge — much longer than a lettuce, which makes it the head to buy when the week is uncertain.

Can it sit out?
Radicchio 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 radicchio has gone bad
- Outer leaves gone brown and papery
- A slimy base where the leaves meet the core
- Leaves gone dull and limp instead of taut
- A sour smell from inside the head
When in doubt, throw it out.
Radicchio ages from the outside in — strip the tired outer leaves and the head underneath is usually still crisp.
