Store cut, raw butternut squash in an airtight container or plastic bag. Store cooked butternut squash in a shallow, airtight container.

Freezer

10 to 12 months (cooked/pureed)

Peel, seed, cut into pieces, cook until tender, then mash or puree. Cool completely before freezing in airtight containers or freezer bags. Can also be frozen raw after blanching.

Signs of Spoilage

  • Soft spots or mushy texture
  • Mold growth (fuzzy white, green, or black spots)
  • Off-odor (sour or fermented smell)
  • Discoloration (dark spots or unusual changes in color)
  • Slimy or sticky surface

Room Temperature Safety

2-hour rule (1 hour if ambient temperature is above 90°F / 32°C)

40°F–140°F (4°C–60°C)

Perishable foods, including cut or cooked butternut squash, should not be left at room temperature for more than 2 hours. If the temperature is above 90°F (32°C), discard after 1 hour.

Expert Tips

Safe Handling

1

Wash hands thoroughly with soap and water before and after handling squash.

2

Wash whole butternut squash under running water, scrubbing with a clean produce brush, before cutting.

3

Use separate cutting boards and utensils for raw produce to prevent cross-contamination.

Cook butternut squash to a tender consistency. If reheating cooked squash, ensure it reaches an internal temperature of 165°F (74°C).
