Seasonal Eating With a CSA Box: A Beginner's Guide

A CSA (Community Supported Agriculture) box delivers whatever's actually in season near you — which means some weeks you'll get vegetables you've never cooked before. Here's what to expect, how to cook the unfamiliar stuff, and how to keep it from going to waste when a box gets ahead of you.

What's Actually in the Box

Expect the produce to look different from grocery-store vegetables — sun-warmed, a little dirty, often misshapen — because it's picked closer to ripe rather than bred to survive shipping. It's also common to get vegetables that don't show up in a regular grocery run: fava beans, shishito peppers, radishes, and purslane are all typical CSA surprises.

Learning to Cook What You Get

Two cookbooks are especially useful for figuring out unfamiliar CSA produce: The French Market Cookbook by Clotilde Dusoulier, and The Gardener and the Grill by Karen Adler and Judith Fertig. A few simple preparations worth trying:

• Thinly slice radishes and serve them on crusty bread with butter.
• Toss fava beans with Parmesan cheese.
• Broil shishito peppers with olive oil and sea salt — they end up tasting close to popcorn.
• Use fresh pesto to dress up whatever vegetable you're least sure what to do with.

When the Box Gets Ahead of You

CSA boxes don't wait for your schedule, and a heavy week can leave you with more produce than you'll eat before it turns. Freeze-drying the overflow — the same way you would with garden surplus — extends its shelf life well past the point fresh produce would spoil, and it means nothing from that week's box goes to waste. Our guide to freeze-drying the harvest covers the basics, and if it's late-summer abundance specifically, freeze-drying your August garden applies just as well to CSA overflow as it does to a home garden.

Finding What's in Season Near You

If you're not in a CSA but want to eat seasonally on your own, Epicurious publishes an interactive seasonal produce map by state that's worth checking before you shop. And once you've got seasonal produce on hand — CSA or otherwise — our summer recipes built around freeze-dried garden vegetables are a good place to start using it.

Frequently Asked Questions

What kind of vegetables show up in a CSA box?
Whatever's in season locally, which often includes less common produce like fava beans, shishito peppers, radishes, and purslane alongside more familiar vegetables.

What's the best way to cook shishito peppers?
Broil them with olive oil and sea salt — the char and salt combination ends up tasting close to popcorn.

What should I do if my CSA box gives me more produce than I can eat in time?
Freeze-dry the overflow. It extends the produce's shelf life well past when it would otherwise spoil, so a heavy week doesn't turn into wasted food.

How do I know what produce is in season in my area?
Epicurious publishes an interactive seasonal produce map by state that's a quick way to check before you shop, even without a CSA subscription.
