What's in Season in October?

Pumpkins, winter squash, and new-harvest sweet potatoes — beta-carotene season is here.

October is peak pumpkin culture, but the nutrition story is bigger than jack-o’-lanterns: pie pumpkins, butternut, and acorn squash are all concentrated sources of beta-carotene, which the body converts to vitamin A for immune function and eye health. Butternut squash also brings potassium — about 329mg per 100g — and enough natural sweetness to make vegetables an easy sell.

The first frosts sweeten Brussels sprouts and kale, new-harvest sweet potatoes arrive from North Carolina, and apple season peaks with late varieties like Granny Smith. Cranberry harvest begins in Wisconsin and Massachusetts bogs, kicking off the run-up to the holidays. Roast, soup, and batch-cook — October produce is built for it.
