Can it sit out?
Cut spaghetti squash 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 cut spaghetti squash has gone bad
- A cut face gone tacky or slimy
- Dark, water-soaked patches in the flesh
- A sour smell through the wrap
- Fuzzy mold in the seed cavity
When in doubt, throw it out.
Roast it cut-side down until the strands pull free with a fork — steaming leaves them watery.
