Xiaolongbao is a steamed, soup-filled dumpling with a thin, pleated wrapper. Shengjianbao is pan-fried, sits on a yeasted dough base, and carries less liquid inside. Both are pork dumplings native to Shanghai. But they behave differently in your hand. That difference should decide which one you order first.
Visitors often assume the two are the same dish under different names. They are not. One is cooked in its own broth inside a sealed wrapper. The other is a fried bun, with only a fraction of that liquid.
What actually separates them
Xiaolongbao (小笼包) means “small steamer basket bun.” The name describes how it is cooked, not what is inside. Pork filling is mixed with a jellied stock. It’s made from pork skin and bones, simmered until it sets solid when cold. Steaming melts that jelly back into broth, sealed inside the dough by a twisted, pleated top. Nothing escapes until a diner bites through the skin.
The dish is credited to Nanxiang. It’s a market town now folded into Jiading district, on Shanghai’s northwestern edge. Nanxiang Mantou Dian is a restaurant still trading at Yu Garden (Yuyuan), in the old walled city. It is widely cited as tracing its xiaolongbao recipe to the late Qing dynasty. The Michelin Guide’s Shanghai selection lists the restaurant — outside verification beyond its own house history.
Shengjianbao (生煎包) means “raw-fried bun.” It starts as a yeasted dough, not the unleavened wrapper xiaolongbao uses. That dough is thicker, and it absorbs some of the meat juices as it cooks. The bun sits in an oiled pan, bottom down, until it browns and crisps. Water or a light batter is added and the pan is covered, so the top steams while the base fries. Sesame seeds and chopped scallion usually finish the top. Less liquid survives this process. Shengjianbao is not dry, but it carries nowhere near the volume xiaolongbao does.
The two dumplings, side by side
- Wrapper — Xiaolongbao: thin, unleavened dough, pleated shut at the top. Shengjianbao: thicker, yeasted dough, open at the top.
- Cooking method — Xiaolongbao: steamed in a bamboo basket. Shengjianbao: pan-fried on the base, steamed under a lid on top.
- Soup volume — Xiaolongbao: a spoonful or more of broth per piece, from melted pork-jelly filling. Shengjianbao: a small pocket of juice, reduced by frying.
- Filling temperature — Xiaolongbao: broth close to boiling, because steam cannot escape a sealed wrapper. Shengjianbao: cooler filling, because steam vents continuously during frying.
- Base texture — Xiaolongbao: soft all over. Shengjianbao: crisp, browned base that acts as a seal against spills.
- Usual serving — Xiaolongbao: commonly ordered by the steamer basket, often eight to ten pieces. Shengjianbao: ordered by count, often four to six pieces per plate.
Which one to order depends on where you’re standing
The real choice isn’t about taste. It’s about circumstance — specifically, whether you’re seated or on your feet.
Choose shengjianbao when eating standing up, walking toward a metro entrance, or holding a phone in one hand. Its fried base is thick and mostly sealed. Even if the top skin tears, the filling is unlikely to run down your wrist. There’s little soup to spill in the first place. What’s left has usually cooled by the time it reaches the counter.
Choose xiaolongbao when seated, with a spoon, a napkin, and at least ten minutes before you need to move. The broth inside is close to boiling. Sealed steam doesn’t lose heat the way a frying pan vents it. Bite too early while standing, and the payoff is a scalded lip or a soup stain, not a quick snack.
How to eat either without a mess
For xiaolongbao, lift one dumpling by the pleated top with chopsticks. Rest it on a spoon — don’t hold it in the air over the table. Bite a small hole in the side, not the top, and let steam escape for a few seconds. Sip the broth from the hole. Only then dip the empty dumpling in the vinegar-and-ginger dish usually served alongside, and eat the rest in one bite.
Shengjianbao needs less ceremony. Bite through the crisp base first, where there’s no soup to spray. Then work up through the softer top. The vinegar dish, if offered, is optional rather than traditional here.
Finding either, and paying for it
Nanxiang Mantou Dian sits inside the Yu Garden (Yuyuan) bazaar, near a metro station on Line 10. Confirm the exact station and exit on a current map before setting out — Google Maps does not work in mainland China, so Amap or Baidu Maps are the standard workaround, a gap covered in more detail in our audit of blocked apps and broken 2FA.
For shengjianbao, Yang’s Fry Dumplings (小杨生煎) is one of the most widely franchised chains carrying the dish across the city, with dozens of branches rather than one address to remember. Time Out Shanghai and other city guides have covered its spread from a single Shanghai shop into a multi-branch operation.
Street-facing dumpling counters vary in what they accept. Many now run on Alipay or WeChat Pay by default, with cash or card as a fallback rather than the norm. Setting up either app with a foreign card before arriving saves a queue at the till — see our guide to setting up Alipay or WeChat Pay with a foreign card. The same apps, and the same advance setup, also carry you through everyday payments in Shanghai generally.
If the dumpling stop is also your last one before heading home, check the closing time for that specific line. The Shanghai Metro shuts somewhere between roughly 22:00 and 23:00, depending on the line and direction — earlier than in Tokyo or Seoul, and never the same across the network. Details are in our piece on last-train times, and the fare mechanics themselves — including the requirement to tap or scan out, not just in — are covered in how to pay for the Shanghai Metro. Both sit within our wider Getting Around archive.
Access Shanghai’s editorial team has not eaten at either restaurant named here. Both are cited because they appear in the public record — a Michelin listing, and coverage in independent city guides — rather than on our own say-so. How this site sources, checks, and discloses that is set out on our about page.
