Early Fall at the Union Square Greenmarket, and Who's Cooking It

The Union Square Greenmarket runs Monday, Wednesday, Friday and Saturday, 8am to 6pm, and by early September the tables have started shifting from late-summer tomatoes and corn toward the first apples, winter squash and cool-weather greens. Two Italian kitchens within a few minutes of the market build that shift into their own menus rather than running the same plates year-round. Here’s what’s changing at the market this month, and where it shows up on a plate nearby.

At a Glance

• Market days: Monday, Wednesday, Friday, Saturday, 8am–6pm, at the north and west sides of Union Square Park.
• This month at the market: GrowNYC’s Fermentation Fest runs Friday, September 12, 10am–5pm; FLOCK, a celebration of regional fiber and wool, runs Friday, September 26, 10am–5pm.
• What’s turning over: late tomatoes and sweet corn are on their way out; the first apples, and decorative and sugar pumpkins, are showing up at most stands through Thanksgiving.
• Where to eat it: Isabelle’s Osteria, on Park Avenue South, and Tarallucci e Vino’s Union Square flagship, on East 18th Street.

Why September Is a Hinge Month at This Market

Union Square is Greenmarket’s flagship location, with more vendors and a wider range of produce than almost any other stand in the city. Early September is a transition point rather than a single clean handoff: you’ll still find the tail end of summer tomatoes and stone fruit next to the season’s first apples and the earliest winter squash. A kitchen that actually shops here, rather than ordering off a standing produce list, shows that overlap on the plate — a menu that’s visibly different from what it was in July, without having jumped straight to November root vegetables.

Two Events Worth Building a Trip Around

If you’re already planning to walk the market this month, GrowNYC has scheduled two events that turn a produce run into something worth timing a visit around. Fermentation Fest, on Friday, September 12 from 10am to 5pm, focuses on preserving and fermenting the last of the summer harvest. FLOCK, on Friday, September 26 from 10am to 5pm, is built around regional fiber and wool rather than food, but it’s a reason to be at the market on a Friday when the produce stands are also fully stocked. Confirm both dates on GrowNYC’s own site before you plan around them, since Greenmarket programming can shift.

Where the Market Shows Up on a Menu: Isabelle’s Osteria

Isabelle’s Osteria, at 245 Park Avenue South, is about a seven-minute walk from the market’s south end, and its menu is built around seasonal Italian dishes rather than a fixed year-round lineup. That makes it a natural stop right after a market walk, particularly if you want a kitchen that’s actually responding to what’s in season rather than treating “seasonal” as a marketing word. It suits a diner who wants a sit-down dinner after a Saturday market morning, or a lighter Aperitivo Hour visit on a weekday — the restaurant runs that window Monday through Friday from 5pm. Check Isabelle’s current dinner and aperitivo menus directly on its own site, since a kitchen built around the market changes those menus more often than a set trattoria list.

A Second Option: Tarallucci e Vino, Union Square

Tarallucci e Vino’s flagship, at 15 East 18th Street, is the closer of the two to the market itself — a two-minute walk from the park’s southwest corner. It opens early, from 8am most days, which makes it one of the few Italian rooms in the immediate area that can handle a coffee and pastry stop before the market gets busy, not just a dinner after. Hours run 8am to 10pm Monday, 8am to 10:30pm Tuesday through Thursday, later on Friday and Saturday, and 11am to 10pm Sunday. It’s the practical pick if your plan is market first, then a full day, rather than market as a prelude to one dinner.

Building a Market Morning Into an Evening

The Greenmarket’s Monday/Wednesday/Friday/Saturday schedule means a weekday visit is possible without waiting for the weekend, and pairing an early walk with a later dinner at either kitchen gives you a full read on what a genuinely seasonal Union Square menu looks like right now, rather than what it looked like in July or what it’ll look like in November. If you’re coming from north toward Gramercy rather than starting at the square itself, Irving Place is the more direct walk down.

Frequently Asked Question

Does the Union Square Greenmarket run in the winter, or does it shut down after fall?

The Union Square Greenmarket runs year-round on its regular Monday, Wednesday, Friday and Saturday schedule; it doesn’t close for winter, though the produce mix shifts hard toward root vegetables, stored apples, and greenhouse greens once the fall harvest is done. Decorative and sugar pumpkins stay on most tables through Thanksgiving before the market moves fully into its winter lineup. If you’re planning a specific ingredient-driven visit later in the year, checking GrowNYC’s own seasonal notes closer to the date is more reliable than assuming this September lineup will still be there in December.

Walk the market on one of its four open days this month, then decide between an early stop at Tarallucci or a full dinner at Isabelle’s based on how the rest of your day is shaped.
