Winter's best produce is smaller in variety than other seasons but still worth building meals around: citrus fruit like oranges and grapefruit, hearty greens like kale and collards, and whatever root vegetables carried over from fall. Most of this pairs naturally with slow-cooked stews and braises, since cold weather and long cook times just go together. Here's what's in season and how to cook through the colder months.
What's in season in winter?
Winter produce leans on things that either grow in cold weather or store well through it. Citrus is the main fresh bright spot, with most varieties peaking from December through March, especially in warmer growing regions like California and Florida. The table below is a general guide; exact timing shifts depending on your region and the specific citrus variety.
| Produce | Peak months (US, general) | Simple way to use it |
|---|---|---|
| Citrus (oranges, grapefruit, mandarins) | December to March | Eat raw, segment into salads, or juice |
| Kale and collard greens | November to March | Braise with garlic and stock, or massage raw into salad |
| Cabbage | November to March | Roast in wedges, or braise with butter and vinegar |
| Winter squash and root vegetables (stored) | Through winter | Roast, or add to stews and braises |
| Leeks | October to April | Sauté in soups, or braise whole in butter |
Why does citrus peak in winter instead of summer?
Citrus trees actually need a period of cooler nights to develop full sweetness and color in the fruit, which is why the harvest lands in winter even though we associate citrus with sunshine. California and Florida supply most of the US market during these months, so winter is genuinely the best time to buy oranges and grapefruit, not just the only time.
What's the best way to cook hearty greens like kale or collards?
Raw kale can be tough and bitter; a slow braise breaks it down into something closer to comfort food.
- Strip the leaves from the tough center stems and roughly chop.
- Sauté sliced garlic in olive oil over medium heat until fragrant, about 1 minute.
- Add the greens in batches, letting each batch wilt before adding more.
- Pour in a splash of stock, cover, and simmer on low for 20-30 minutes, until tender.
- Finish with a splash of vinegar or a squeeze of lemon to brighten it back up.
A ham hock or a few strips of bacon added at the start turns this into a more substantial side, simmered the same way but longer, closer to 45 minutes.
