Here is a detailed recipe for Chicken Nanban (チキン南蛮), a beloved Japanese dish from Miyazaki Prefecture that features tender, fried chicken topped with a sweet-sour nanban sauce and creamy tartar sauce.
Chicken Nanban Recipe
This dish is known for its unique preparation: the fried chicken is briefly dipped in a sweet and tangy sauce right after frying, which keeps it incredibly juicy and flavorful.
Ingredients:
For the Chicken:
- Chicken Thighs: 2 boneless, skin-on or skinless (about 500g / 1 lb)
- Salt and Black Pepper: to taste
- All-Purpose Flour: ½ cup for dusting
- Egg: 1 large, beaten (for the egg wash)
- Neutral Oil: for frying (e.g., canola, vegetable)
For the Nanban Sauce:
- Rice Vinegar: ¼ cup
- Soy Sauce: 3 tablespoons
- Sugar: 3 tablespoons
- Mirin: 2 tablespoons
- Bird’s Eye Chili: 1-2, deseeded and thinly sliced (or 1 tsp chili flakes)
For the Tartar Sauce:
- Mayonnaise (Kewpie preferred): ½ cup
- Hard-Boiled Egg: 1, finely chopped
- Onion: 2 tablespoons, finely minced (red or white)
- Pickles/Relish: 2 tablespoons, finely chopped (dill pickles or sweet relish)
- Lemon Juice: 1 teaspoon
- Salt and White Pepper: a pinch
Common Sides:
- Shredded cabbage
- Lemon wedges
Instructions:
1. Prepare the Sauces (Do this first):
- Nanban Sauce: In a small saucepan, combine the rice vinegar, soy sauce, sugar, and mirin. Heat over medium until the sugar dissolves. Stir in the sliced chili peppers. Remove from heat and pour into a wide, shallow bowl (big enough to dip the chicken). Let it cool.
- Tartar Sauce: In a separate bowl, mix all the tartar sauce ingredients together. Cover and refrigerate until ready to use.
2. Prepare the Chicken:
- Pat the chicken thighs completely dry with paper towels. Cut each thigh into 3-4 large bite-sized pieces.
- Season both sides generously with salt and black pepper.
- Place the flour in one shallow dish and the beaten egg in another.
3. Fry the Chicken:
- Heat about 1 inch (2.5 cm) of oil in a deep skillet or pot to 170°C (340°F).*
- Dredge each piece of chicken first in the flour, shaking off the excess, then dip it thoroughly into the beaten egg.
- Carefully place the chicken in the hot oil. Don’t overcrowd the pan; fry in batches if needed.
- Fry for about 5-7 minutes, turning occasionally, until golden brown and cooked through. The internal temperature should reach 74°C (165°F).
4. The Key Nanban Step:
- As soon as each piece of chicken comes out of the fryer, immediately dip it into the prepared Nanban Sauce. Swirl it around for a few seconds to coat it completely and let the excess drip off.
- This step soaks the hot chicken with the flavorful sauce, making it incredibly juicy.
5. To Serve:
- Place the sauced chicken pieces on a serving plate lined with shredded cabbage.
- Generously dollop the chilled tartar sauce over the top of the warm chicken.
- Serve immediately with a lemon wedge on the side.

Pro Tips for Authentic Chicken Nanban:
- No Thermometer? Test the oil by dropping a small bit of flour into it. If it sizzles immediately and floats to the top, it’s ready.
- Kewpie Mayo: Using Japanese Kewpie mayonnaise is highly recommended for the tartar sauce, as its unique flavor is a key part of the dish.
- Juicy Chicken: Using boneless chicken thighs is traditional as they stay juicier than breasts during frying. Do not skip the post-fry sauce dip!
- Make Ahead: The nanban sauce and tartar sauce can be made a day in advance and stored in the fridge.
