This quick and easy air fryer char siu chicken transforms ordinary chicken thighs into a sticky, sweet, and savory delight reminiscent of the classic Chinese barbecue favorite. The air fryer makes this traditionally time-consuming dish achievable on busy weeknights, delivering that perfect char and glaze in just minutes.
I first started making this recipe when my traditional oven broke during a family gathering. The air fryer saved dinner that night, and the results were so impressive that I haven't gone back to the conventional method since.
Ingredients
- 1 lb skin-on bone-in chicken thighs: Choose thighs with even thickness for consistent cooking.
- ⅓ cup red fermented bean curd: This is the secret ingredient that gives authentic char siu its distinctive flavor and color.
- ¼ cup hoisin sauce: Adds sweetness and depth to the marinade.
- ¼ cup brown sugar: Light or dark both work well, providing caramelization and balance.
- ⅓ cup regular soy sauce: Creates the salty foundation of the marinade.
- 2 tablespoon honey or maple syrup: Adds glossiness and helps create that sticky glaze.
- 2 tablespoon Shaoxing wine: Brings complexity and removes any gamey flavor from the chicken.
- 1 teaspoon Chinese five spice: This aromatic blend ties all the flavors together.

Step-by-Step Instructions
- Prepare the marinade:
- Combine all chicken marinade ingredients in a large bowl. The red fermented bean curd will be chunky at first, so use a fork to smash it until reasonably smooth. This creates the base flavor of traditional char siu.
- Prepare the chicken:
- Pat your chicken thighs completely dry with paper towels. This crucial step ensures the marinade adheres properly. Using a sharp knife, make small incisions around the bone until you can remove it while keeping the skin intact. The skin provides moisture and that coveted crispy texture.
- Marinate the chicken:
- Submerge chicken thighs fully in the marinade, ensuring all surfaces are covered. Cover the bowl and refrigerate for at least 15 minutes, though overnight marination will yield the most flavorful results as it allows the flavors to fully penetrate the meat.
- Make the basting sauce:
- In a separate small bowl, combine the basting sauce ingredients. Use a fork to thoroughly incorporate the fermented bean curd into a smooth consistency. This sauce will create that beautiful lacquered finish that char siu is famous for.
- Prepare for air frying:
- Lightly spray your air fryer basket with cooking oil to prevent sticking. Arrange the marinated chicken pieces skin side up in a single layer. Never overlap pieces as this prevents proper air circulation. Generously brush the basting sauce over the skin side.
- Air fry to perfection:
- Cook at 375°F for 9-10 minutes without flipping. The chicken is done when the thickest part registers 165°F on an instant-read thermometer and the meat shows no pink or translucency. The edges should develop a beautiful char that mirrors traditional char siu.
- Rest and serve:
- Allow the chicken to rest for 5 minutes before slicing. This crucial step allows the juices to redistribute throughout the meat, ensuring each bite stays moist and flavorful.

The red fermented bean curd is what makes this recipe truly special. I remember the first time I opened a jar, my entire family gathered around wondering about the strange aroma. Now, we all recognize it as the unmistakable signature of homemade char siu, and this ingredient has earned a permanent spot in my refrigerator.
Oven Baking Method
For those without an air fryer, you can achieve similar results in a conventional oven. Preheat your oven to 425°F and line a baking sheet with foil or parchment for easy cleanup. Place the marinated chicken skin side up, baste generously, and bake for 20-23 minutes on the middle rack until the internal temperature reaches 165°F. The slightly higher temperature helps achieve that signature char while keeping the inside juicy.
Adaptable to Different Cuts
This marinade works wonderfully with various chicken cuts. For boneless chicken breasts, reduce cooking time to 6 minutes on the first side and 3-8 minutes on the second side, removing at 155-160°F to let residual heat finish the cooking process. This prevents the lean meat from drying out. For chicken wings, the higher fat content allows for cooking at 400°F for about 12-13 minutes total, creating extra crispy skin with juicy meat inside.

Serving Suggestions
Traditional char siu is often served with fluffy white rice and steamed vegetables for a complete meal. For a more elaborate spread, pair with quick cucumber pickles and a simple bok choy stir-fry. The sweet and savory flavors of this chicken also work beautifully in homemade fried rice or tucked into steamed bao buns with fresh scallions and hoisin sauce for an impressive appetizer that guests will rave about.
Storage and Leftovers
Store any leftover char siu chicken in an airtight container in the refrigerator for up to 3 days. The flavors actually intensify overnight, making next-day leftovers even more delicious. For meal prep, slice the cooled chicken and portion with rice and vegetables for quick lunches throughout the week. You can also freeze portions for up to 2 months. Thaw overnight in the refrigerator and reheat in the air fryer at 350°F for 3-4 minutes to restore that delicious outer texture.
