How to Make Baked Char Siu Bao

1. Prepare the Dough: Begin by heating the milk until warm but not boiling. Add the instant yeast and sugar, stirring gently. Let it bloom for about 5 minutes until frothy, which indicates the yeast is active.

2. Mix the Ingredients: In a large bowl, combine bread flour and salt. Create a well in the center, then add the egg and the milk mixture. Mix until a shaggy dough forms.

3. Knead the Dough: Transfer the dough to a floured surface. Knead for about 10 minutes, adding softened butter gradually, until the dough is smooth and elastic. It should feel slightly tacky but not sticky.

4. Proof the Dough: Place the kneaded dough into a lightly greased bowl, cover it with a damp cloth, and let it rise in a warm spot until doubled in size, approximately 1 hour.

5. Make the Filling: In a skillet, heat a little vegetable oil over medium heat. Saut shallots and garlic until fragrant, about 3 minutes. Stir in the remaining filling ingredients and let the mixture thicken slightly, about 5 minutes. Remove from heat and fold in the diced char siu.

6. Assemble the Buns: Once the dough has doubled, punch it down and divide it into 12 equal pieces. Shape each piece into a ball, then flatten into a disc. Spoon some filling into the center of each disc, pinch the edges together to seal, and shape them into smooth balls.

7. Second Proofing: Place the assembled buns seam-side down on a parchment-lined baking sheet. Cover and let them rise for another 30 minutes until puffy.

8. Bake: Preheat your oven to 375 °F (190 °C). Brush the tops of the buns with egg wash for a beautiful golden finish. Bake for 15-20 minutes or until golden brown. Allow them to cool slightly on a wire rack.

Optional: Sprinkle with toasted sesame seeds before serving for added flavor and crunch.

Baked Char Siu Bao Recipe FAQs

How do I choose ripe ingredients for this recipe?
Absolutely! When selecting shallots and garlic, look for firm bulbs with smooth skin, avoiding any with dark spots or soft spots. For char siu, if you re buying pre-made, choose a batch that appears moist and has a vibrant color. If you make it from scratch, ensure the pork is tender and cooked well, providing that essential flavor profile.

How should I store leftover Baked Char Siu Bao?
To keep these buns fresh, store any leftovers in an airtight container in the refrigerator for up to 5 days. This method helps maintain their softness while keeping the flavor intact. Remember to reheat them individually in the microwave for quick enjoyment!

What if my dough doesn t rise?
Very frustrating, I know! If your dough doesn t rise, it could be due to inactive yeast.

If your kitchen is cool, consider placing your dough in a warmer area or using a warm oven with a bowl of hot water to assist in the rising process.

Are these buns suitable for people with dietary restrictions?
Great question! If you need to accommodate allergies, ensure to check the sauces and ingredients for gluten, especially if you use soy sauce. For a vegetarian option, substitute char siu with plant-based meat alternatives or mushrooms. Always double-check specific ingredients for allergens that may apply to your guests.

Can I make these buns ahead of time?
Yes, you can! Feel free to prepare the buns up to the second proof stage, then cover them tightly and refrigerate. They can be stored like this overnight or for up to 24 hours. Just allow them to come to room temperature and proof for about 30 minutes before baking the next day, ensuring you still achieve that perfect fluffiness!
