Sanxing Scallion Pancake

Bursting scallion whites, made to order on a griddle — the signature of the Lanyang River alluvial plain
📍 Yilan · Sanxing Tian­song­bi🏆 Iconic · Street Food🌿 A whole bunch of scallions, pressed onto the griddle

Sanxing scallion pancake is a signature street food of Tiansongbi in Sanxing Township, Yilan, made by wrapping a whole bunch of Sanxing scallions directly into dough and pan-frying it half-deep-fried, bursting with scallion whites and served fresh off the griddle. On a Tiansongbi afternoon, the scallion aroma arrives before the sound of traffic. On the iron griddle, flatbreads stuffed with whole bunches of scallions are pressed by a wooden spatula, filling the air with sizzling sounds as green tops poke out from the edges, and everyone in line is already holding a bag of hot, freshly made pancakes. This is the most straightforward hospitality Sanxing Township has to offer: take the best produce from the fields and stuff it generously into a pancake.

According to the Ministry of Agriculture's Food and Agriculture Education Platform, Sanxing scallions have white stalks reaching 18 to 20-plus centimeters — well beyond the roughly 10 centimeters typical of scallions grown in southern Taiwan — with fine fiber, low pungency, and a naturally sweet flavor, making it the officially recognized agricultural specialty of Sanxing Township.

What is a Sanxing Scallion Pancake?

A Sanxing scallion pancake is not the thin, crispy layered style common in Taipei. Instead, it is a thick version made by wrapping a whole bunch of chopped Sanxing scallions directly into a dough skin, then pan-frying and shallow-deep-frying together. The two most common varieties are plain scallion pancake and scallion-pork pancake, the latter adding a portion of ground pork. The moisture in the scallions turns to steam at high heat, puffing up the dough into air pockets. Bite in and the outer shell is crispy while the inside is soft, juicy, and bursting with scallion fragrance — bold but not sharp.

Sanxing Township sits on the upper alluvial fan of the Lanyang River, where large day-night temperature swings and clean water sources prevail. The Council of Agriculture's Food and Agriculture Education Platform explicitly notes that Sanxing scallions have the longest white stalks, the finest fiber, and the lowest pungency of any scallion in Taiwan — making the township the universally recognized premier scallion-growing region. Local pancake stalls source directly from nearby fields; the time from field to pan is often under a day. That "freshly harvested, freshly fried" window is the key element impossible to replicate outside Yilan.

How to eat it like a local

🔥
First bite within three minutesThe pancake is crispiest within three minutes of leaving the griddle. Once it cools, the dough softens and the scallion aroma fades by half. Don't rush to take photos when you finally get yours.
🌶️
Go easy on the chili sauceSanxing scallions are naturally sweet. Locals usually eat them plain or with just a little house-made chili sauce. Too much sauce drowns out the scallion flavor.
🥩
Try the scallion-pork versionThe plain version highlights scallion fragrance; the pork version adds fat and saltiness. If you're hungry, buy one of each and compare.
🚗
Stroll along the Annong River afterwardThe Tiansongbi area sits right along the Annong River. After eating, a walk along the riverbank aids digestion, and you can continue to Wei Zhen Xiang for burou — a perfect itinerary loop.

  • The Council of Agriculture's Food and Agriculture Education Platform Scallion Culture Hall records: Sanxing scallions are renowned for their longest white stalks and finest fiber, and are Yilan's signature agricultural product.

Visitor tips

  • On weekends around midday, queues can exceed 30 minutes. Arriving earlier on weekdays or timing your visit during the afternoon lull is much more comfortable.
  • Scallion pancakes are greasy, so leave a small gap at the top of the bag to prevent them from steaming and softening. If eating in the car, lay down a napkin first.
  • Scallion season runs roughly from November through April of the following year. It is normal for scallion prices to spike after summer typhoons — don't assume the stalls are raising prices unfairly.
