What's in Season: September Fruits & Vegetables

Summer takes its final bow — and fall steps in with some of the year's most satisfying produce.

September is a month of beautiful transition. The heat softens, the light shifts, and the produce aisle tells the story better than any calendar could. Summer's most beloved staples — tomatoes, corn, peppers — are still here, but they're winding down. And sliding in alongside them are the first real harbingers of fall: apples, pears, winter squash, and root vegetables that signal the season ahead.

It's one of the most abundant and versatile months of the year to eat locally and seasonally. Here's what to reach for in September.

🍎 Apples

September is apple season in full swing. After the delicate early varieties of late August, the main harvest arrives this month with depth and diversity — Honeycrisp, Cortland, McIntosh, Fuji, Empire, and dozens of regional varieties depending on where you live. Crisp, complex, and built to store, fall apples are equally at home eaten raw, baked into a crisp, pressed into cider, or sliced alongside cheese for an effortless snack.

Tip: September is the ideal time to visit a local orchard if one is near you — u-pick apples are often a fraction of the grocery store price and far more flavorful. Buy a bulk bag and store in the fridge crisper drawer; most fall varieties keep for weeks.

🍐 Pears

Pears are one of September's quiet highlights — understated next to apples but deeply rewarding in their own right. Bartlett pears peak early in the month, giving way to Bosc and Anjou as September progresses. Unlike most fruit, pears ripen best off the tree and at room temperature; once they yield slightly to gentle pressure near the stem, they're ready. Eat fresh, poach in spiced wine, roast alongside pork, or slice thin over a salad with walnuts and blue cheese.

Tip: Pears are one of the few fruits that don't ripen well on the tree. Buy them slightly firm and let them ripen on your counter — check daily, as the window between underripe and overripe can be surprisingly short.

🎃 Winter Squash

The first winter squash of the season arrives in September — butternut, acorn, delicata, kabocha, and spaghetti squash all begin showing up at farm stands and markets this month. These are the workhorses of fall cooking: roast them simply with olive oil and salt, blend into silky soups, stuff and bake, or cube into grain bowls and salads. Their thick skins mean they store beautifully for weeks or even months, making them one of the most practical seasonal buys of the year.

Tip: Delicata squash is worth seeking out — its skin is thin enough to eat (no peeling required), and it roasts into caramelized, tender rings in about 25 minutes. A great gateway squash for anyone who finds butternut too labor-intensive.

🍅 Late Summer Tomatoes

Tomatoes are still here in September, and in many regions they're at their most concentrated and complex — the result of long, slow ripening through summer heat. These late-season tomatoes are ideal for cooking: roast them low and slow to intensify their sweetness, simmer into a rich sauce to freeze for winter, or make one final batch of fresh salsa before the season closes. Don't let September pass without making a big pot of tomato sauce from scratch — you'll be glad you did in February.

Tip: If you have access to an abundance of ripe tomatoes this month, roasting and freezing them is one of the highest-value preservation projects of the year. Halve, drizzle with olive oil, roast at 300°F for two hours, and freeze in portions.

🌽 End-of-Season Corn

September marks the tail end of sweet corn season, and in many regions the final weeks of corn are among the sweetest. Don't let it slip by without one last batch of corn chowder, a final grilled corn salad, or a simple succotash made with whatever else is still coming out of the late summer garden. Once it's gone, it's gone until next year.

Tip: End-of-season corn tends to be starchier than peak summer corn — it's better suited to soups, chowders, and cooked preparations than eating raw off the cob.

🥦 Broccoli & Cauliflower

Cool-weather brassicas thrive in September's moderating temperatures, and broccoli and cauliflower are at their tender, sweet best this month. Summer heat makes brassicas bitter and prone to bolting; fall's cooler nights bring out a natural sweetness that makes these vegetables genuinely worth looking forward to. Roast until deeply caramelized, steam and toss with good butter, or use cauliflower as the base for a creamy fall soup.

Tip: Broccoli florets should be tight and dark green with no yellowing — yellowing means the broccoli is past its prime and starting to flower. Smaller heads often have more concentrated flavor than large ones.

🥕 Carrots & Root Vegetables

Root vegetables come into their own as soil temperatures drop in September — carrots, parsnips, turnips, and beets are all hitting their stride. Fall carrots in particular develop a natural sweetness as the plant converts starches to sugars in response to cooler temperatures. Roast a sheet pan of mixed root vegetables with herbs and olive oil, blend beets into a vibrant soup, or use parsnips in place of potatoes for something a little different.

Tip: Carrots with their tops still attached are typically fresher than those sold in bags. If you buy them with greens, remove the tops before storing — they draw moisture from the root.

🍇 Grapes (Peak Season)

September is the heart of grape harvest season — the time when vineyards are at their most active and fresh table grapes are at peak flavor. Concord grapes, with their deep purple skin and intensely musky flavor, are at their absolute best this month and worth seeking out at farmers markets even if you've never cooked with them. Use them for homemade jam, grape juice, or simply eat by the bunch while they last.

Tip: Concord grapes have seeds and slip-skins — the flesh slides easily out of the skin. They're not the same eating experience as seedless table grapes, but the flavor is in a completely different league.

🌰 Chestnuts & Hazelnuts

Early nuts begin arriving in September — chestnuts and hazelnuts are among the first, with the main walnut and pecan harvests following in October. Fresh chestnuts are a revelation compared to the canned version: roast them over an open flame or in the oven, score the shells first, and peel while still warm. Hazelnuts are wonderful toasted and folded into baked goods, blended into spreads, or used to finish pasta and salads.

Tip: Score chestnuts with an X before roasting — this prevents them from exploding and makes peeling dramatically easier. Peel while warm; they become difficult to remove once cooled.

🥬 Kale, Chard & Fall Greens

September's cooler temperatures bring out the best in hearty greens — kale, Swiss chard, collards, and arugula are all thriving this month, sweeter and more tender than their summer counterparts. This is the time to build the salads, braises, and soups that will carry you through the colder months ahead. Massaged kale salads, white bean and chard stews, and arugula with roasted pears and walnuts are September staples for good reason.

Tip: Kale becomes significantly more tender and less bitter after a light frost — if you're growing it or buying from a local farm, the best kale of the year often comes after the first cold snap of fall.

Shop What's in Season

September is a month worth paying attention to at the market. The overlap of summer's final gifts and fall's first arrivals makes it one of the most interesting and abundant months of the year — and one of the best for stocking up, preserving, and cooking ahead.

Eating with the season is one of the simplest sustainable choices you can make. The food is better, the footprint is lower, and the connection to the natural world is one that's easy to lose and genuinely worth keeping.
