Can it sit out?
Frozen polenta 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 frozen polenta has gone bad
- A sour smell from a thawed tube
- A slippery or sticky film on the cut surface
- Mold spots on the end — toss the tube, don’t trim it
- A grainy texture weeping water after thawing
When in doubt, throw it out.
Pat thawed slices dry before they hit the oil — the water it weeps will steam them instead of crisping them.
