Storage
To keep your zucchini and squash fresh and flavorful, follow these tips:
- Refrigerate: Store whole, unwashed zucchini and squash in the cripser drawer of your refrigerator. Place them in a resuable mesh product bag or vented plastic bag. Avoid store with fruit as the ethylene can cause them to ripen and spoil faster.
- Cut Zucchini: I like to prep my zucchini and squash for quick use. Store it in a plastic container lined with a dry paper towel to absorb moisture. It will last about four to five days.
- Cooked Zucchini: Store cooked zucchini and squash in an airtight container in the refrigerator. I use leftovers in my Copycat Viand Diner Vegetable Soup or add them to breakfast with eggs.
