Ingredients for Chicken Siopao

Simple dough ingredients and a flavorful chicken filling create these authentic steamed buns.

The flour forms the base—King Arthur or Gold Medal all-purpose work perfectly. Yeast must be fresh (check the expiration date) for proper rise. For the filling, thighs stay juicier than breasts during steaming. Most Asian markets carry oyster sauce, but larger supermarkets like H-E-B or Kroger often stock it too. The dough needs time to rise—don’t rush this step.

No oyster sauce? Hoisin sauce at half the amount works as a substitute. Chicken breasts can replace thighs (but may be less tender). Fresh ginger is ideal, but ground ginger at one-third the amount in a pinch. For a vegetarian version, swap chicken for mushrooms or tofu. The soy sauce should be fresh—old soy sauce loses its punch.

Dough can rest overnight in the fridge for deeper flavor. Filling keeps 2-3 days refrigerated. Assembled buns freeze well for up to 1 month—steam straight from frozen, adding 5 extra minutes. Always bring filling to room temperature before using.

Step-by-Step Instructions for Chicken Siopao

This method ensures tender buns with a rich, flavorful filling every time.

Step 1: Activate the Yeast and Prepare the Dough

In a small bowl, combine the 1 package Active Dry Yeast with the 1 cup Warm Water and let it sit for 5-10 minutes until it becomes frothy. This confirms the yeast is active and ready to leaven your dough.

In a large mixing bowl, whisk together the 3 cups All-Purpose Flour, 0.25 cup Granulated Sugar, and 1 tbsp Baking Powder. Pour in the yeast mixture and 2 tbsp Vegetable Oil, then stir until a shaggy dough forms. The dough should pull away from the sides of the bowl but remain slightly sticky.

Turn the dough onto a lightly floured surface and knead for 8-10 minutes until smooth and elastic. The dough is ready when it springs back slowly when pressed with a finger.

Step 2: Make the Chicken Filling

In a saucepan, heat a small amount of oil over medium heat. Add the minced 4 cloves Garlic Cloves and 1 tbsp Fresh Ginger, sautéing until fragrant—about 30 seconds. Be careful not to let them burn, as this will make the filling bitter.

Add the diced 1 lb Boneless Chicken Thighs and cook until the meat is no longer pink, about 5-7 minutes. Stir in the 3 tbsp Soy Sauce, 2 tbsp Oyster Sauce, and 1 tbsp Brown Sugar. Simmer for 5 minutes to allow the flavors to meld.

In a small bowl, mix the 1 tbsp Cornstarch with 2 tbsp of water to create a slurry. Stir this into the chicken mixture and cook for another 2-3 minutes until the filling thickens into a glossy, rich sauce. Remove from heat and set aside to cool.

Step 3: Assemble and Steam the Siopao

Divide the risen dough into 12 equal portions and roll each into a smooth ball. Flatten each ball into a 3-inch circle, leaving the center slightly thicker than the edges. This ensures the bun can hold the filling without tearing.

Place a spoonful of the cooled chicken filling in the center of each dough circle. Gather the edges of the dough around the filling, pinching them together to seal completely. Twist the sealed edges gently to ensure a tight closure, which prevents the buns from opening during steaming.

Line a steamer basket with parchment paper, ensuring there are small holes poked in it to allow steam to circulate. Arrange the siopao in the basket, leaving 1 inch of space between each bun to allow for expansion. Cover and let them rest for 15 minutes.

Step 4: Steam to Perfection

Bring water to a rolling boil in a pot that fits your steamer basket. Place the basket over the pot, ensuring the bottom doesn’t touch the water. Steam the siopao over high heat for 15-20 minutes.

Check the water level periodically to ensure it doesn’t evaporate completely. The siopao are done when the dough has puffed up and feels firm to the touch. Avoid lifting the lid during the first 10 minutes to prevent the buns from collapsing due to sudden temperature changes.

Remove the siopao from the steamer and brush the tops with 1 tsp Sesame Oil for a glossy finish. Garnish with thinly sliced 3 whole Green Onions before serving warm. Each bun should have a soft, fluffy texture with a juicy, flavorful filling.

Serving Suggestions for chicken siopao

Traditional Presentation

Serve these buns hot from the steamer in their parchment paper liners for an authentic touch. The paper prevents sticking and makes handling easier. I like arranging them on a bamboo steamer tray for a restaurant-style presentation. 🥢

Dipping Sauce Pairing

Offer a simple dipping sauce of 2 tbsp soy sauce mixed with 1 tsp rice vinegar and ½ tsp chili oil. This adds an extra layer of flavor that complements the filling. For a sweeter option, use banana ketchup—a Filipino favorite.

Meal Combinations

Pair with sinangag (Filipino garlic fried rice) and a side of atchara (pickled papaya) for a complete meal. The tangy crunch of atchara cuts through the richness of the buns beautifully.

Party Platter Idea

For gatherings, arrange on a large platter with small dipping bowls in the center. Include calamansi wedges for guests to squeeze over their buns. This citrus touch brightens the flavors. ✨

Breakfast Twist

Serve with hot chocolate or coffee for a hearty breakfast. The warmth of the buns pairs perfectly with a steaming cup. I often make extra filling for breakfast burritos the next day.

Garnishing Tip

Finish with extra green onions and a drizzle of sesame oil just before serving. This adds freshness and a glossy sheen that makes them look as good as they taste.
