Bao buns, also known as gua bao (刈包) or lotus leaf buns (荷葉包), are soft, fluffy steamed buns that are a staple in Chinese, Taiwanese, and East Asian cuisine. These light, slightly sweet buns are often stuffed with savory fillings like braised pork belly, crispy tofu, or Peking duck, making them a beloved street food across Asia.
Unlike baked bread, bao dough is steamed, resulting in a cloud-like texture that melts in your mouth. Whether served plain, filled, or folded like a sandwich, bao buns are a versatile canvas for a wide range of flavors.

The Origins & Cultural Significance of Bao Buns
- Ancient Chinese Roots 🇨🇳
Baozi (包子), the steamed bun family, originated in China over 1,800 years ago. The famous military strategist Zhuge Liang is credited with inventing baozi as a portable, filling food. - Taiwanese Gua Bao (刈包)
One of the most famous versions, gua bao, features a folded, taco-like steamed bun filled with braised pork belly, pickled mustard greens, crushed peanuts, and cilantro. - Bao Buns in Modern Cuisine
Today, bao buns have become a global sensation, appearing in restaurants worldwide, often with creative fusion fillings like Korean fried chicken, barbecue pork, or crispy tofu.
📌 Fun Fact: In Taiwan, gua bao is often called “tiger bites pig” (虎咬猪) because the bun looks like a mouth biting into the pork belly!
Key Ingredients for Soft, Fluffy Bao Buns
To achieve light, airy bao buns, you need the right balance of ingredients and careful steaming.
🥢 Essential Ingredients:
- All-Purpose Flour – Provides a soft, fluffy texture.
- Instant Yeast – Helps the dough rise, making the bao light and airy.
- Milk or Water – Adds moisture and softness.
- Sugar – Adds subtle sweetness and helps feed the yeast.
- Baking Powder – Ensures extra fluffiness.
- Neutral Oil (Vegetable or Peanut Oil) – Keeps the dough tender.
📌 Pro Tip: Using low-protein flour (like cake flour) makes bao buns even softer!
Step-by-Step Recipe: How to Make Perfect Bao Buns from Scratch
🛒 Ingredients (Makes 8-10 Bao Buns)
For the Dough:
- 2½ cups (300g) all-purpose flour
- 1 tbsp sugar
- 1 tsp instant yeast
- ½ tsp baking powder
- ½ cup warm milk (or water for a vegan version)
- 1 tbsp neutral oil (vegetable or peanut oil)
For Steaming:
✔ Parchment paper squares (to prevent sticking)
✔ Steamer basket (bamboo or metal)
🔪 Instructions
1. Prepare the Dough
- In a bowl, whisk together flour, sugar, baking powder, and yeast.
- Add warm milk and oil, mixing until a dough forms.
- Knead for 8-10 minutes until smooth and elastic.
- Cover and let rise for 1 hour (or until doubled in size).
📌 Pro Tip: The dough should be soft but not sticky—add a little flour if needed!
2. Shape the Bao Buns
- Punch down the dough and divide it into 8-10 equal pieces.
- Roll each piece into an oval shape (~¼-inch thick).
- Lightly brush one side with oil, then fold in half to create the signature folded bao bun shape.
- Place each bun on a small parchment paper square to prevent sticking.
📌 Why Add Oil? The oil prevents the two sides from sticking together after steaming!
3. Let the Buns Rest (Second Rise)
- Cover the shaped buns with a damp cloth and let them rest for 30 minutes.
- This allows the yeast to activate again, ensuring fluffiness.
📌 Pro Tip: Do NOT overproof the dough—too much rising makes the bao dense instead of airy!
4. Steam the Bao Buns
- Heat water in a steamer pot or bamboo steamer until boiling.
- Place bao buns with space between them (they will expand!).
- Steam over medium heat for 8-10 minutes.
- Turn off heat and let the buns rest in the steamer for 5 minutes before opening the lid.
📌 Why Rest the Buns After Steaming? Opening the lid too quickly causes the bao to collapse due to sudden temperature changes.

📌 Pro Tip: Experiment with flavors! Bao buns go well with duck, shrimp, or even jackfruit for a plant-based option!
Tips for Steaming the Perfect Bao
- Use a Bamboo Steamer – It absorbs excess moisture, preventing soggy bao.
- Line the Steamer with Parchment Paper – Keeps bao from sticking.
- Steam Over Medium Heat – High heat can make bao wrinkly or tough.
- Leave Space Between Buns – They expand as they cook!
- Let the Buns Rest Before Opening the Lid – Prevents collapsing.
📌 Want Extra Softness? Add ½ tbsp vinegar to the steaming water for whiter, fluffier bao!
How to Serve & Store Bao Buns
- Serve Fresh & Warm – Bao is best enjoyed right after steaming.
- Store Leftovers – Keep in an airtight container in the fridge (2-3 days).
- Reheat by Steaming – Steam for 3-4 minutes to refresh the texture.
- Freeze for Later – Store in the freezer for up to 2 months and reheat as needed.
📌 Quick Hack: If using store-bought bao, microwave for 30 seconds with a damp paper towel for instant fluffiness!
