Vietnamese Rice Dumpling Recipe: Savory Bánh Ú at Home

Vietnamese rice dumplings, known in many southern Vietnamese kitchens as bánh ú, are pyramid-shaped parcels of glutinous rice wrapped in leaves and boiled until tender. This savory version encloses mung bean and seasoned pork in the rice, making a filling dumpling with a fragrant, pleasantly chewy exterior. Family recipes and regional versions vary: some bánh ú are sweet, and the leaf, filling, and shape can differ.

Ingredients

3 cups (600 g) glutinous rice, also called sweet rice or sticky rice
1 cup (200 g) hulled split mung beans
1 lb (450 g) boneless pork shoulder, cut into roughly ¾-inch (2 cm) pieces
1 small shallot, finely minced, about ¼ cup (30 g)
2 tablespoons (30 ml) fish sauce
1 tablespoon (15 ml) soy sauce
1 teaspoon (4 g) granulated sugar
½ teaspoon (1 g) freshly ground black pepper
1 tablespoon (15 ml) neutral oil, such as canola oil
1 teaspoon (5 g) fine salt, divided
20 dried bamboo leaves, to allow for two leaves per dumpling and a few spares
8 lengths cotton kitchen twine, each about 36 inches (90 cm)
Water, for soaking and boiling; have about 3 quarts (2.8 L) of boiling water ready for topping up the pot

Instructions

Soak the rice and mung beans. Rinse the glutinous rice in several changes of cool water until the water is less cloudy. Cover it generously with fresh water and soak for 4 hours. In a separate bowl, rinse the mung beans, cover with water, and soak for 2 hours; this can happen during the rice soak. Drain both well. Letting them drain while you prepare the leaves helps prevent excess water from making the dumplings gummy.
Prepare the leaves. Rinse the dried bamboo leaves, then soak them in hot water for 30 minutes, or until pliable. Wipe both sides clean with a damp cloth and trim off any tough stems. Keep the leaves covered with a clean damp towel while you work so they do not dry or crack. If a leaf splits, set it aside as an extra inner layer rather than relying on it to hold the filling.
Season and cook the pork. Warm the oil in a saucepan over medium heat. Add the shallot and cook for about 2 minutes, stirring, until softened. Add the pork, fish sauce, soy sauce, sugar, pepper, and ½ teaspoon of the salt. Stir to coat, then add ½ cup (120 ml) water. Bring to a gentle simmer, cover, and cook for about 35 minutes, stirring once or twice, until the pork is tender and the liquid has reduced to a light coating. Check a large piece with a food thermometer: USDA FSIS lists 145°F (63°C) with a 3-minute rest as the safe minimum for whole cuts of pork. Rest the cooked pork for 3 minutes, then spread it on a plate and let it cool for 20 minutes before wrapping.
Season the rice and beans. Toss the drained rice with the remaining ½ teaspoon salt. Drain the mung beans very thoroughly. For a smooth, traditional-style filling, steam the beans over simmering water for about 20 minutes until soft, then mash them roughly with a fork. If your beans are still firm, steam for a few minutes longer; they should hold together when pressed, not be wet or soupy.
Shape the leaves. Lay two pliable bamboo leaves across each other, shiny sides facing out, with the stems pointing in opposite directions. Overlap them enough to make a broad, sturdy sheet. Curl the sheet into a cone, keeping the point closed and the wide opening at the top. Set the cone upright in a small bowl or cup while filling it; this support makes the first few parcels easier to shape.
Fill and tie the dumplings. Add about ⅓ cup (65 g) of rice to the cone and press it gently into the point and along the sides. Add about 2 tablespoons (30 g) of mashed mung beans and a few pieces of pork, then cover with another ⅓ cup (65 g) rice. Use the remaining leaves to fold the open top over the rice, forming a compact pyramid with no visible gaps. Tie firmly enough to hold the shape, but not so tightly that the rice has no room to expand. Repeat to make 8 parcels. If you have extra rice or filling, distribute it evenly rather than packing one dumpling too full.
Boil until tender. Arrange the dumplings snugly in a large, heavy pot and cover them completely with water. Bring the water to a boil, then lower the heat to maintain a steady simmer. Cover and cook for 3 hours 30 minutes. Check the pot occasionally; the parcels must stay submerged, so top it up with boiling water as needed. Avoid adding cold water, which can interrupt the simmer and extend the cooking time.
Drain and serve. Lift the dumplings out with tongs and let them drain in a colander for about 10 minutes. Allow them to cool until comfortable to handle, then snip the twine and peel back the leaves. Serve warm. If you prefer a firmer rice texture, let the unwrapped dumplings stand for another 10 minutes before eating.

Tips

Soak, then drain well. Glutinous rice needs a long soak to cook evenly in a wrapped parcel. Give it the full 4 hours, but drain it thoroughly before seasoning; water clinging to the grains can make the cooked rice overly soft.
Use flexible leaves and leave expansion room. Dried bamboo leaves are sold in Asian grocery stores, often in bundles. If you cannot find them, use banana leaves cut into sturdy sections; they are softer and more likely to need overlapping layers, and their flavor is milder. Do not use parchment as the sole wrapper because it will not provide the same secure, traditional parcel.
Keep the packets closed without crushing them. A loose fold can let water enter and rice escape, while an extremely tight tie can split the leaves as the rice swells. Make a small test fold with spare leaves if you have not shaped a pyramid dumpling before.
Plan for the long cook. Use a pot with a lid and enough room for water to circulate around the parcels. Keep a kettle of hot water nearby for topping up, and do not leave a large pot simmering unattended for extended periods.

Serving Suggestions

Serve bánh ú warm as a substantial snack, breakfast, or part of a meal. Open the leaf just before eating so the rice stays warm and fragrant. A small dish of fish sauce with sliced chile is a simple accompaniment; for a less salty option, offer soy sauce with fresh chile on the side. The pork and mung bean already bring savory depth, so start with a light dip and add more only as needed.

For a fuller meal, pair one dumpling with quick-pickled carrots or daikon, cucumber, or a crisp green salad dressed with lime and a little fish sauce. The fresh, sharp flavors balance the soft, rich filling. You can also serve the dumplings alongside steamed greens or a light broth. If serving several people, leave the parcels wrapped on a platter and let everyone unwrap their own at the table; the leaves help retain warmth and make the portions easy to handle.

Variations

For a pork-free filling, replace the pork with 8 ounces (225 g) of sautéed shiitake mushrooms and ½ cup (75 g) finely diced firm tofu. Season them with the same fish sauce, soy sauce, sugar, and pepper, or use a vegetarian fish-sauce substitute. The filling will be less meaty and a little more delicate, so keep it well drained before assembling.

You can change the pork seasoning by adding ½ teaspoon (1 g) five-spice powder or a small pinch of ground white pepper. These are optional accents, not required ingredients, and they will give the filling a warmer, more aromatic profile. For a simpler filling, leave out the mung beans and use a little more pork, though the dumplings will lose the creamy, earthy layer that makes this version distinctive.

Sweet bánh ú are a different but familiar direction: use a sweet mung bean filling and serve the dumpling as a snack or dessert. Recipes vary, and some sweet versions use different rice treatments or fillings, so do not assume that the savory timing and proportions will suit every sweet style. If you want a smaller portion, divide the ingredients into 10 parcels and begin checking tenderness near the end of the same simmer; smaller bundles may cook sooner.

Storage and Reheating

Refrigerate cooked dumplings within 2 hours of cooking. Keep them wrapped or place them in an airtight container; they will keep for 3 to 4 days in the refrigerator. For longer storage, freeze the cooled dumplings in a sealed freezer-safe container for up to 2 months for best texture. Thaw overnight in the refrigerator, or reheat from frozen for longer.

To reheat, steam the dumplings over simmering water for about 20 to 30 minutes from refrigerated, or until hot throughout. From frozen, allow roughly 35 to 45 minutes, checking that the center is steaming hot. If reheating a portion that contains pork, use a food thermometer and bring leftovers to 165°F (74°C), the USDA FSIS reheating temperature. You can microwave an unwrapped portion in short intervals with a damp paper towel over it, but steaming gives the rice a softer, less dry texture. Do not leave cooked dumplings at room temperature for more than 2 hours.

Frequently Asked Questions

What does bánh ú mean?
Bánh ú is a Vietnamese name used for pyramid-shaped rice dumplings, including savory versions wrapped in leaves. The exact filling and preparation vary by region and household; the recipe here uses glutinous rice, mung beans, and pork.

Can I make these without bamboo leaves?
Yes. Banana leaves are the most practical substitute if you can find them. They are more pliable but less rigid, so overlap extra layers and tie the parcels securely. Their aroma is gentler than bamboo leaves. If neither is available, it is better to choose another dumpling recipe than to expect a loose paper wrapper to behave like leaves during a long boil.

Why did my dumplings turn mushy?
Common causes are rice that was not drained well, filling packed with excess liquid, or parcels that were loosely folded and allowed water inside. Measure the rice after draining only by volume as listed, make sure the mung beans and pork filling are not wet, and keep the leaves sealed while tying. The long simmer is intentional; a tight, water-resistant wrap helps the rice cook evenly without becoming waterlogged.

Can I prepare the dumplings ahead?
Yes. You can soak the rice and beans, cook the filling, and assemble the parcels a day ahead. Keep the uncooked dumplings covered in the refrigerator and boil them the next day; chilled parcels may need a little extra time, so check the rice for tenderness before removing them. For best results, do not leave soaked rice at room temperature for hours after draining.

How can I tell when a dumpling is done?
After the full simmer, remove one parcel and let it cool enough to open safely. The rice should be tender all the way through, with no hard or chalky center, and the mung bean should be soft. If the center is still firm, rewrap the test parcel if possible and continue simmering the rest for 20 to 30 minutes before checking again.

Can I use regular rice instead of glutinous rice?
No, regular long-grain or jasmine rice will not produce the same cohesive, chewy texture. Glutinous rice is also called sweet rice; despite the name, it is not sweetened. Look for it in Asian grocery stores or the international aisle, and check that the package says glutinous or sticky rice rather than simply short-grain rice.
