- 1/4 cup soy sauce
- 2 tablespoons hoisin sauce
- 2 tablespoons honey or brown sugar
- 2 tablespoons rice vinegar
- 3 cloves garlic, minced
- 1-inch piece of ginger, minced
- 1 teaspoon five-spice powder
- 1/2 cup water or chicken stock
For the Steamed Buns:
- 12 store-bought or homemade steamed buns (or substitute with soft slider buns)
For the Toppings:
- 1 cup pickled vegetables (carrots, daikon, or mustard greens)
- 1/2 cup fresh cilantro leaves
- 1/4 cup crushed peanuts
- 1/4 cup sliced green onions
- Sriracha or chili sauce (optional, for spice lovers)
For the Pickled Vegetables (Optional):
- 1 cup rice vinegar
- 1/2 cup sugar
- 1 teaspoon salt
- 1 cup julienned carrots or daikon radish
Step-by-Step Instructions
1. Prepare the Pork Belly
- Score the Skin: Use a sharp knife to score the pork belly skin in a crisscross pattern. This helps render the fat and crisp the skin.
- Marinate: In a bowl, mix soy sauce, hoisin sauce, honey, rice vinegar, garlic, ginger, and five-spice powder. Rub the marinade all over the pork belly, ensuring it gets into the scored skin.
- Cook the Pork Belly:
- Preheat the oven to 325°F (160°C).
- Place the pork belly in a baking dish, skin-side up, and add water or chicken stock to the dish.
- Cover with foil and roast for 2 hours.
- Remove the foil, increase the oven temperature to 425°F (220°C), and roast for another 20-30 minutes to crisp the skin.
- Rest and Slice: Let the pork belly rest for 10 minutes, then slice it into thin pieces.
2. Prepare the Pickled Vegetables (Optional)
- In a small saucepan, combine rice vinegar, sugar, and salt. Heat until the sugar dissolves.
- Place the julienned vegetables in a jar and pour the hot vinegar mixture over them.
- Let cool, then refrigerate for at least 1 hour before using.
3. Steam the Buns
- If using store-bought buns, follow the package instructions to steam them until soft and warm.
- If making homemade buns, prepare the dough, shape into buns, and steam for 10-12 minutes.
4. Assemble the Buns
- Open each steamed bun and layer with slices of pork belly.
- Top with pickled vegetables, fresh cilantro, crushed peanuts, and green onions.
- Drizzle with sriracha or chili sauce if desired.
5. Serve and Enjoy
- Serve the Pork Belly Buns immediately while warm.
- Pair with a side of extra pickled vegetables or a light salad for a complete meal.
Tips for Perfect Pork Belly Buns
- Crispy Skin: Ensure the pork belly skin is dry before scoring and roasting. Pat it dry with paper towels.
- Balance Flavors: Adjust the sweetness, saltiness, and tanginess of the marinade and toppings to suit your taste.
- Make Ahead: The pork belly and pickled vegetables can be prepared a day in advance for easier assembly.
- Homemade Buns: If you have time, making steamed buns from scratch adds an extra layer of authenticity.

Creative Variations
- Spicy Pork Belly Buns: Add sliced jalapeños or a spicy mayo drizzle.
- Vegetarian Option: Substitute pork belly with braised tofu or mushrooms.
- Korean-Inspired: Use gochujang (Korean chili paste) in the marinade and top with kimchi.
- Fusion Style: Add a slice of avocado or a drizzle of sesame sauce for a unique twist.
Serving Suggestions
- As an Appetizer: Serve 1-2 buns per person as a starter.
- As a Main Course: Pair with a side of steamed rice or a light soup.
- For Parties: Set up a DIY bun station with all the toppings for guests to assemble their own.
