Japanese Shumai (焼売) are tender, juicy steamed dumplings filled with seasoned ground pork, onions, and aromatic seasonings, all wrapped in thin shumai wrappers. Popular in Japanese homes, bento boxes, dim sum restaurants, and convenience stores, Shumai are loved for their soft texture, savory flavor, and elegant appearance. Unlike gyoza, shumai are left open at the top, allowing the flavorful filling to remain moist while steaming.

Whether served as an appetizer, lunch, or part of a Japanese feast, homemade Shumai are surprisingly easy to make and incredibly delicious.


What is Shumai?

Shumai is a Japanese adaptation of the Chinese siu mai, featuring a juicy filling of ground pork, finely chopped onions, ginger, and seasonings wrapped in a thin wheat wrapper. The dumplings are shaped into small cylinders with an open top and steamed until tender.

Japanese Shumai is commonly enjoyed with soy sauce, Japanese mustard (karashi), or ponzu sauce.

Kitchen Equipment

  • Mixing bowl
  • Steamer or bamboo steamer
  • Parchment paper
  • Spoon
  • Knife
  • Cutting board

Preparation Time

  • Prep Time: 30 minutes
  • Cook Time: 15 minutes
  • Total Time: 45 minutes

Servings: 24–30 shumai


Step 1: Prepare the Onion

Place the finely diced onion in a bowl.

Sprinkle with cornstarch and toss until evenly coated.

This helps bind the filling while keeping it juicy.


Step 2: Make the Filling

In a large bowl, combine:

  • Ground pork
  • Coated onions
  • Garlic
  • Ginger
  • Soy sauce
  • Sesame oil
  • Sake
  • Sugar
  • Salt
  • White pepper

Mix thoroughly until the filling becomes sticky and well combined.


Step 3: Wrap the Shumai

Hold a shumai wrapper in your hand.

Place about 1 tablespoon of filling in the center.

Gently press the wrapper upward around the filling while shaping it into a small cylinder with an open top.

Flatten the bottom slightly so the shumai stands upright.

Top with a green pea, carrot cube, or corn kernel if desired.


Step 4: Prepare the Steamer

Line the steamer with parchment paper or cabbage leaves to prevent sticking.

Arrange the shumai in a single layer, leaving a little space between each dumpling.


Step 5: Steam

Bring water to a gentle boil.

Steam the shumai over medium-high heat for 10–12 minutes, or until the pork is fully cooked and the wrappers become translucent and tender.


Step 6: Serve

Transfer the hot shumai to a serving plate.

Serve immediately with soy sauce, karashi mustard, or ponzu sauce.


Garnish

Top with:

  • Finely sliced green onions
  • Toasted sesame seeds
  • Shredded ginger
  • Fresh cilantro (optional)
  • Lemon wedges

  • Steamed Japanese rice
  • Miso soup
  • Gyoza
  • Fried rice
  • Yakisoba
  • Japanese potato salad
  • Pickled vegetables (Tsukemono)
  • Green tea

Tips for Perfect Shumai

  • Coat the onions with cornstarch to keep the filling moist.
  • Mix the filling until it becomes sticky for better texture.
  • Avoid overfilling the wrappers.
  • Leave the tops open for the traditional appearance.
  • Don't overcrowd the steamer.
  • Steam just until cooked to maintain a juicy filling.

Delicious Variations

Shrimp Shumai

Replace half of the pork with finely chopped shrimp for a sweeter seafood flavor.


Chicken Shumai

Use ground chicken instead of pork for a lighter version.


Crab Shumai

Mix imitation crab or fresh crab meat into the filling for extra umami.


Mushroom Shumai

Add finely chopped shiitake mushrooms for a rich, earthy taste.


Vegetarian Shumai

Fill with tofu, mushrooms, cabbage, carrots, and edamame for a meat-free alternative.


Storage

Store cooked shumai in an airtight container in the refrigerator for up to 3 days.

Freeze uncooked shumai on a tray until firm, then transfer to a freezer-safe bag for up to 2 months.

Steam directly from frozen, adding an extra 3–5 minutes to the cooking time.

Frequently Asked Questions

What is the difference between Shumai and Gyoza?

Shumai are open-topped dumplings that are steamed, while gyoza are crescent-shaped dumplings that are typically pan-fried and steamed. Shumai wrappers are also thinner and shaped differently.

Can I use wonton wrappers?

Yes. Square wonton wrappers can be cut into smaller squares if shumai wrappers are unavailable.

How do I know when shumai are cooked?

The filling should reach an internal temperature of 71°C (160°F) for pork, and the wrappers should be tender and slightly translucent.

Can I make shumai ahead of time?

Yes. Assemble the dumplings a day in advance and refrigerate them, or freeze them for longer storage.

What dipping sauce goes best with Shumai?

Soy sauce with Japanese mustard (karashi) is the classic choice. Ponzu sauce, chili oil, or a mixture of soy sauce and rice vinegar are also excellent options.
