Xiao Long Bao (Soup Dumplings)

Juicy pork soup dumplings with a gingery broth inside, steamed until the wrappers go glossy and the filling turns into a tiny bowl of soup you can pick up.

Xiao long bao is the kind of food that makes you slow down. Not because it is fussy (although, yes, there is some folding), but because the first bite demands a little respect. You pick it up, you set it on a spoon, you nibble a vent, you slurp the soup, then you go in for the rest. It is dinner and a tiny ceremony.

The magic is simple and very nerdy in the best way: we set a rich broth with gelatin into a soft “soup jelly,” dice it up, and mix it into a pork filling. In the steamer, the jelly melts, and suddenly you have broth trapped inside a dumpling. Bright ginger, scallion, a little Shaoxing wine, and that clean porky sweetness do the rest.

Measured ingredients for xiao long bao on a bright kitchen counter including ground pork, ginger, scallions, soy sauce, Shaoxing wine, gelatin, flour, and a bamboo steamer.

Why It Works

  • Real soup inside: A firmly set gelatin aspic melts as the dumplings steam, giving you that signature slurp.
  • Tender, springy filling: Mixing the pork with a little chilled liquid and stirring in one direction helps it bind and stay juicy.
  • Thin but sturdy wrappers: A hot water dough makes the skins easier to roll thin without tearing.
  • Steam without sticking: Napa cabbage or parchment liners keep the bottoms intact and the vibes calm.

Storage Tips

Storage Tips

Best move: freeze before steaming

Xiao long bao is at its best freshly steamed, but it freezes beautifully uncooked.

  • Freeze uncooked: Arrange dumplings in a single layer on a parchment-lined sheet pan. Freeze until solid, then transfer to a freezer bag. Freeze up to 2 months.
  • Steam from frozen: No thawing. Add 2 to 3 minutes to steaming time.

If you already steamed them

  • Refrigerate: Store in an airtight container up to 2 days.
  • Reheat: Steam 3 to 4 minutes until hot. Microwaving tends to toughen wrappers and can make soup leak out in dramatic ways.

Steaming in batches

If your steamer only fits a few at a time, keep the waiting dumplings chilled so the aspic stays firm and the wrappers do not get sticky.

Common Questions

Common Questions

What gives xiao long bao its soup?

In this recipe, gelatin. We set a concentrated broth with gelatin into a firm aspic, dice it, and fold it into the filling. In the steamer, the gelatin melts back into hot soup.

My aspic is soft. What do I do?

Gelatin strength varies by brand. If your aspic is still soft after a full chill (and it will not dice cleanly), re-melt it gently and whisk in 1/2 packet (about 1 teaspoon) more gelatin. Re-chill until firm.

Can I use store-bought wrappers?

Yes. Look for Shanghai-style dumpling wrappers if you can find them. Regular round dumpling wrappers work too, but they are often thicker. Roll each one a bit thinner around the edges for a better bite.

Do I need a bamboo steamer?

It helps because it breathes and reduces condensation drip. But a metal steamer works fine. Just keep the lid wrapped in a clean towel to catch condensation so your dumplings do not get soggy on top.

Why are my dumplings leaking?

  • Wrapper got too thin in one spot or tore while pleating.
  • Not enough pleats or the top was not sealed tight.
  • Dumplings stuck to the steamer and ripped when lifted. Use napa cabbage leaves or parchment rounds.

How many pleats should I aim for?

Traditional is 18 to 22, but your goal is simpler: even gathers and a tight seal. If you hit 12 to 16 neat pleats and nothing leaks, you are winning dinner.

What is the dipping sauce for xiao long bao?

Classic is Chinkiang black vinegar with julienned ginger. A tiny drop of chili oil is optional but highly encouraged.

The first time I ate xiao long bao the right way, someone slid a spoon under my dumpling like they were defusing a tiny delicious bomb. “Bite a corner first,” they said, and I did, and then I understood why people get poetic about dumplings. At home, my first batch looked like wrinkly money bags and a few definitely sprang leaks. Still incredible. Now I treat xiao long bao like a team project where everyone is allowed to be imperfect as long as the soup shows up. If you get one perfect dumpling in the bunch, you will immediately want to make them again.
