Crispy Chicken Karaage Bao Buns with Kewpie Mayo Step-by-step instructions

Before you start

Before starting, gather all ingredients and equipment. Cut the chicken into 1- to 2-inch chunks. Grate the ginger. Measure the soy sauce and sake. Set up a wire rack over a baking sheet for draining the fried chicken. Fill a deep pot with enough neutral oil for frying – about 2 inches – and attach a deep-fry thermometer.

Have the potato starch in a shallow dish. Prepare the bamboo steamer with water and line it with parchment paper. Set out the purple cabbage (shredded) and sliced scallions for serving. If using frozen bao buns, keep them in the freezer until ready to steam.

Instructions

Marinate and Coat

1. 1Marinate the Chicken
   In a medium bowl, combine the soy sauce, sake, and grated ginger. Add the chicken chunks and toss to coat evenly. Cover and refrigerate for at least 15 minutes, or up to 1 hour for deeper flavor.
   Look for The chicken should be well coated and glossy from the marinade.
   Tip Do not marinate longer than 1 hour – the ginger can make the chicken mushy.
2. 2Dredge in Potato Starch
   Place the potato starch in a shallow dish. Working in batches, add the marinated chicken pieces and toss to coat thoroughly, pressing the starch onto each piece. Shake off any excess and set on a plate.
   Look for Each piece should be completely covered with a dry, powdery coating.
   Tip For extra craggy texture, lightly spray the coated chicken with water and dredge again.

The chicken should be evenly coated with the marinade, with a fragrant aroma of soy, sake, and ginger. After dredging, each piece is covered in a dry, powdery layer of potato starch. The coating should feel like fine sand – not clumpy or wet. This phase sets the stage for a crispy crust.

Fry and Steam

3. 3First Fry at 340°F
   Heat about 2 inches of neutral oil in a deep pot to 340°F (170°C). Carefully add the chicken in batches, without crowding, and fry for 4 minutes, turning occasionally, until pale golden and cooked through.
   Look for The chicken will be light golden and float to the surface.
   Safe temperature 165°F (74°C) internal temperature (poultry)
   Tip Maintain the oil temperature – adjust heat as needed.
4. 4Rest and Flash Fry
   Remove the chicken with a slotted spoon and drain on a wire rack. Let rest for 5 minutes. Increase the oil temperature to 375°F (190°C). Return the chicken to the hot oil in batches and fry for 60 seconds until deep golden and blistered.
   Look for The crust will turn a rich golden brown and sound shatteringly crisp when tapped.
   Safe temperature 165°F (74°C) internal temperature (poultry)
   Tip Do not skip the resting – it ensures a juicy interior and extra-crispy exterior.

The first fry yields pale golden pieces that are cooked through and tender. After the flash fry, the chicken turns deep golden brown with a blistered, craggy surface. The bao buns, meanwhile, have steamed into soft, fluffy pillows that bounce back when pressed. The kitchen smells of warm, yeasty bread and savory fried chicken.

Assemble and Serve

5. 5Steam the Bao Buns
   While the chicken rests, fill a bamboo steamer with water and bring to a simmer. Line the steamer with parchment paper. Place the frozen bao buns in the steamer, cover, and steam for 8 minutes until puffed, warm, and springy.
   Look for The buns should be soft, pillowy, and slightly translucent.
   Tip Keep the buns covered while assembling to stay warm.
6. 6Assemble the Bao
   Gently open a warm bao bun. Tuck in a few pieces of crispy chicken, add a handful of shredded purple cabbage, drizzle with Kewpie mayo, and sprinkle with sliced scallions. Serve immediately.
   Look for The bun should be warm and fluffy, the chicken crispy and hot.
   Tip Use chopsticks to hold the bun together while eating.

The assembled bao buns are a beautiful contrast: the golden-brown chicken peeks out from the white bun, with purple cabbage adding a vibrant pop of color and Kewpie mayo drizzled in zigzags.

The first bite delivers an audible crunch, followed by the juicy chicken and the cool, creamy mayo. Everything should be served immediately, while the buns are warm and the chicken is at peak crispness.

Common mistakes

One common mistake is overcrowding the pot during frying, which lowers the oil temperature and results in greasy, soggy chicken. Fry in small batches, leaving plenty of space between pieces. Another pitfall is skipping the resting period between the two fries – this allows the interior to finish cooking without over-browning.

Also, be sure to shake off excess potato starch before frying; too much can create a powdery coating. Finally, don’t over-steam the bao buns – they should be soft but still hold their shape when opened.

How to tell it’s done

The chicken is done when it reaches an internal temperature of 165°F (74°C) – check with an instant-read thermometer inserted into the thickest piece. The first fry should bring it to this temperature, but the second fry ensures the crust is extra crispy.

The bao buns are done when they are puffed, soft, and springy to the touch – about 8 minutes of steaming. They should be warm and pillowy, not dense or doughy.
