Best Practices for Storing Butternut Squash
- Store Whole Squash in a Cool, Dark Place – Uncut butternut squash lasts the longest in a pantry or cellar at temperatures between 50-60°F (10-15°C). Avoid refrigeration unless it’s been cut.
- Refrigerate After Cutting – Once peeled or cubed, store squash in an airtight container in the refrigerator for up to 5 days.
- Freeze for Long-Term Use – Cube raw squash, blanch for 3-5 minutes, and freeze in airtight bags. Alternatively, freeze roasted or mashed butternut squash for easy future meals.
- Avoid Direct Sunlight – Exposure to sunlight can speed up spoilage. Store butternut squash away from windows or heat sources.
- Keep Dry – Moisture can lead to mold. Ensure butternut squash is stored in a dry area to maximize shelf life.
