Oyster Vermicelli Noodles (Dongshi Style) | Chiayi Signature Dish

Dongshi Township sits on the western coast of Chiayi County, with oyster production among the highest in Taiwan. Vendors around the fishing harbor use the day's harvested live oysters for their broth — bone stock enriched with oyster liquor forms the base, and the vermicelli noodles soak it up until thick and silky. The oysters are plump, sweet, and briny with the sea. This is a bowl of noodles that exists because of where it is made — impossible to replicate elsewhere.

What Are Oyster Vermicelli Noodles (Dongshi Style)

The noodle broth is built from pork bones and oyster liquor, thickened with sweet potato starch to a dense, smooth consistency. The bowl is finished with freshly blanched live oysters, cilantro, and a small amount of ginger shreds for fragrance and to balance any fishiness. The Dongshi version's defining characteristic is oysters that are large, free of any muddy smell, and springy with a natural sweetness — the seafood flavor speaks for itself without needing garlic paste. The overall texture falls somewhere between a thick broth and congee, rich without being heavy.

Oyster farming in Dongshi Township has a history of more than a hundred years. Farmers primarily use nearshore stick-and-bag cultivation, growing oysters on the abundant plankton along the Budai coastline. Most vendors around the fishing harbor are oyster-farming families who also run food stalls — not a packaged tourist operation. Supply runs mainly from the morning market through the afternoon, with the pace of service following the catch. The peak season runs from November through March of the following year, when the oysters are at their fattest and the broth is sweetest.

How to Eat It the Local Way

🦪

Time It RightVisit between November and March during peak oyster season — the oysters are plump and the broth is at its sweetest. Water temperatures are higher in summer, which slightly reduces quality.

🌅

Arrive Early, Not LateHarbor vendors run mainly in the morning market; some close in the afternoon. Aim to arrive before 10 a.m. for the freshest oysters.

🧄

Go Easy on the SauceDongshi oysters are naturally sweet and clean — for a first taste, skip the garlic paste and try the original flavor before adjusting the seasoning.

🏪

Choose a Family StallPrioritize small family-run stalls around the harbor; the ingredients are usually from their own farm, and the freshness is noticeably higher than versions made with oysters brought in from elsewhere.
