What Koreans Eat in Autumn: Jeoneo, Daeha and the Best Eating Season of the Year (2026)

Ask a Korean which season tastes the best, and most won’t say Chuseok, won’t say kimchi-making in November, and won’t even mention Christmas cake. They’ll say autumn seafood — specifically, the smell of jeoneo sizzling on a charcoal grill at a coastal market. There’s an old saying that the smell of grilled jeoneo brings even the runaway daughter-in-law back home, and it’s repeated every September like clockwork, half joke and half genuine craving. If you’re travelling through Korea between September and November, you’ve landed in the country’s best eating window, and this guide covers what to order, where to find it, and roughly what it costs.

Why autumn is Korea’s best eating season

Korean food culture is deeply seasonal, and autumn is when the biggest number of prized ingredients peak at once. Fish that spent summer feeding are at their fattiest just before winter, west coast prawns are at full size before the cold pushes them offshore, and the year’s pine mushrooms — a genuine luxury item — appear for a few short weeks. Layered on top of all that is Chuseok, Korea’s harvest festival, which turns late September or early October (the date shifts with the lunar calendar, so confirm the exact days on the official calendar each year) into a national celebration of rice, produce and family cooking. Locals plan weekend trips around single ingredients during this stretch — something worth borrowing if you’re building an itinerary. For a broader sense of how food maps onto the Korean calendar year-round, our guide to Korean food culture is a useful companion piece.

Jeoneo: the fish that starts the season

Jeoneo (전어), gizzard shad, is the unofficial mascot of Korean autumn. It runs from roughly September through November, peaking in September, and is almost always served whole, salted, and grilled over charcoal until the skin blisters — bones and all, eaten in a few decisive bites. It’s not a fancy fish and it’s not treated like one; you’ll find it at plastic-table seafood stalls in coastal markets rather than upscale restaurants, and that’s part of the charm. Prices vary by market and by the day’s catch, so treat any number as a rough guide and check the board before ordering — as of 2026, a grilled portion at a coastal market stall is generally an affordable, casual order rather than a splurge, but confirm on-site since it moves with supply. Busan’s fish markets and smaller ports along the south coast are the classic hunting grounds. If seafood-market etiquette feels intimidating on a first visit, our beginner’s guide to Korean seafood markets walks through ordering, pointing, and paying before you go.

Daeha, flower crab and the west coast prawn trip

While jeoneo owns the south coast, the west coast has its own autumn star: daeha (대하), king prawns, in season roughly September to October. The classic preparation is soguemgui — prawns roasted whole on a bed of coarse salt until the shells crisp and the meat turns sweet — and the towns of Hongseong and Anmyeondo run seasonal prawn festivals and roadside grill setups built entirely around it. It’s a genuinely different day trip from anything centred on Seoul or Busan, and worth it if you have a rental car or don’t mind a regional bus. Compare the two coasts and the choice becomes clearer: south coast jeoneo trips lean casual and market-based, while west coast prawn trips lean toward outdoor grill villages and are easier to combine with a beach stop. Autumn is also when flower crab (꽃게) shifts to male crab season, prized for ganjang-gejang (soy-marinated raw crab) and steamed preparations alike — a good middle option if prawns and jeoneo both sound too coastal-specific for your route.

Songi mushrooms and the Chuseok table

Songi (송이), pine mushroom, is the outlier on this list: it’s not cheap, and it’s not meant to be. The season is brief, roughly September into October, concentrated around Yangyang and Bonghwa, and prices run into luxury-gift territory even by Korean standards — treat any figure you see quoted as a starting point and expect real variation by grade, so it’s worth asking before committing to a serving. It shows up thin-sliced and lightly grilled, often at hanwoo beef restaurants where it’s paired with premium meat rather than sold as a standalone dish. Around the same weeks, Chuseok brings its own food traditions to nearly every table in the country: songpyeon, half-moon rice cakes filled with sesame or sweet bean and steamed over pine needles, plus a rotation of jeon (savoury pancakes) that families spend the holiday morning frying together. If your trip lands near the holiday, our Chuseok travel tips page covers what actually stays open, since a lot of small restaurants and markets close for a few days around the date.

Practical tips for eating your way through Korean autumn

A local tip worth knowing before you go: at coastal seafood stalls, prices are frequently quoted by weight or by the tray rather than per person, so it pays to ask the total before the grill starts — a habit that saves confusion at jeoneo and daeha stalls alike. If you’re new to ordering at a Korean restaurant generally, not just a market stall, our Korean restaurant basics guide covers banchan etiquette, paying, and typical service norms. And if seafood isn’t the whole trip for you, pairing one autumn seafood stop with a broader regional food itinerary — temple food, regional stews, market street food — rounds things out nicely; see our regional Korean foods guide for ideas beyond the coast. Whichever route you take, autumn rewards travellers willing to leave central Seoul for a day: the best versions of jeoneo, daeha and songi are all found closer to the water and the mountains than to a hotel restaurant menu.
