Can it sit out?

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.
