Shelf Life of Acorn Squash
- At Room Temperature (Whole, Uncut):
- Fresh Acorn Squash: 1-2 months (stored in a cool, dry place)
- In the Refrigerator:
- Cut or Peeled Acorn Squash (in an airtight container): 3-5 days
- Cooked Acorn Squash: 3-4 days
- In the Freezer (Blanched or Cooked):
- Frozen Acorn Squash (cubed, blanched, or roasted): 10-12 months
Best Practices for Storing Acorn Squash
- Store Whole Squash at Room Temperature – Keep uncut acorn squash in a cool, dry, and well-ventilated area. A pantry or cellar with temperatures between 50-60°F (10-15°C) is ideal.
- Refrigerate After Cutting – Once acorn squash is sliced or peeled, store it in the refrigerator in an airtight container or wrapped tightly in plastic wrap.
- Freeze for Long-Term Storage – To freeze, cube the squash, blanch for 2-3 minutes, cool in ice water, and place in freezer bags. Roasted acorn squash can also be mashed and frozen.
- Keep Dry and Away from Sunlight – Moisture and sunlight can speed up spoilage, so store acorn squash in a dry, shaded area.
- Avoid Refrigerating Whole Squash – Whole acorn squash lasts longer at room temperature than in the refrigerator, where the cold can affect its texture.
Signs Acorn Squash Is Going Bad
- Soft or Sunken Spots – Indicates the squash is beginning to rot.
- Mold or Dark Patches – Any signs of mold or large dark spots mean the squash is no longer fresh.
- Shriveled or Wrinkled Skin – This suggests the squash is drying out, but it may still be usable if cooked soon.
- Unpleasant Smell – A sour or musty odor signals spoilage.
