Karaage is the ultimate Japanese fried chicken: bite-sized pieces of boneless chicken thigh marinated in a savory blend of soy sauce, sake, mirin, sesame oil, fresh ginger, and garlic, then coated in light potato starch and double-fried to shatteringly crispy perfection. The marinade infuses deep umami flavor into every piece, while the double-fry technique delivers a golden, airy crust that stays crunchy even as it cools. Serve it with lemon wedges and Kewpie mayonnaise for an authentic Japanese izakaya experience right at home.

Ingredients
For the Chicken
1.5lbsboneless skinless chicken thighs680g; cut into 1.5 to 2-inch bite-sized pieces
For the Marinade
3tbspsoy sauceJapanese soy sauce preferred, such as Kikkoman or Yamasa
2tbspsakeor substitute dry white wine; helps tenderize chicken and remove gamey odor
1tbspmirinJapanese sweet rice wine; adds subtle sweetness to the marinade
1tsptoasted sesame oiladds nuttiness and depth
1tbspfresh gingergrated with juice; about a 1-inch knob
3clovesgarlicminced or grated
0.5tspwhite pepperor substitute black pepper
For the Coating
1cuppotato starchabout 120g; katakuriko preferred; cornstarch may be substituted but yields a slightly less crispy result
For Frying
neutral oilvegetable, canola, or avocado oil; enough for 3 to 4 inches depth in your pot
For Serving
lemon wedgessqueeze over chicken just before eating to brighten flavors
Japanese Kewpie mayonnaiseoptional but highly recommended for dipping; richer and tangier than standard mayo
Instructions
Pat the boneless chicken thighs dry with paper towels, then trim off any excess fat, cartilage, or tough tendons. Cut each thigh into uniform 1.5 to 2-inch bite-sized pieces and transfer to a large mixing bowl.
Grate the fresh ginger (collecting the juice) and garlic into a small bowl, then add the soy sauce, sake, mirin, sesame oil, and white pepper. Stir until well combined.
Pour the marinade over the chicken pieces and toss to coat every piece thoroughly. Cover the bowl with plastic wrap (or transfer to a zip-lock bag) and marinate for at least 30 minutes at room temperature, or up to 2 hours in the refrigerator. If refrigerating, let the chicken rest at room temperature for 10 to 15 minutes before frying.
Pour enough neutral oil into a deep heavy-bottomed pot to reach at least 3 to 4 inches in depth. Place a wire rack over a baking sheet and set paper towels on a nearby plate to receive the fried chicken.
Remove the chicken from the marinade and press each piece into the potato starch in a shallow tray, turning to coat all sides evenly. Shake off any loose excess starch and let the coated pieces rest for 2 to 3 minutes before frying.
Heat the oil to 320°F (160°C) and fry the chicken in small batches of 4 to 5 pieces for 3 to 4 minutes, turning occasionally, until just cooked through and lightly golden. Remove to the wire rack and allow the oil to return to temperature between each batch.
Allow all the first-fried chicken pieces to rest on the wire rack for at least 5 minutes. This rest is essential for the double-fry method to create a truly crispy crust.
Increase the oil temperature to 375°F (190°C), then return the chicken in batches for 1 to 2 minutes until deeply golden and shatteringly crispy. Remove immediately to the wire rack to drain.
Transfer the karaage to a serving plate and arrange lemon wedges alongside. Serve immediately with Kewpie mayonnaise for dipping, and squeeze fresh lemon juice over the chicken just before eating.
Notes
Always use boneless chicken thighs for karaage. Their higher fat content keeps them juicy through the high heat of deep frying, unlike chicken breast which tends to dry out.
Do not skip the marinating time. A minimum of 30 minutes is needed for the soy sauce, ginger, and sake to penetrate the meat and deliver authentic karaage flavor.
Potato starch (katakuriko) is strongly preferred over all-purpose flour or cornstarch. It creates a significantly lighter, crispier crust. Bob's Red Mill potato starch works well if you can't find katakuriko locally.
A cooking thermometer is essential, not optional. Oil that is too cool produces greasy chicken; oil that is too hot burns the crust before the inside cooks. Aim for exactly 320°F on the first fry and 375°F on the second.
Always fry in small batches of 4 to 5 pieces. Adding too many pieces at once drops the oil temperature and results in a soft, oily coating rather than a crispy crust.
The 5-minute rest between the first and second fry is critical. It allows interior steam to escape and the starch crust to set before the high-heat final fry that creates the crunch.
Sake substitute: If you don't cook with alcohol, replace the sake with dry white grape juice, a splash of rice vinegar diluted with water, or simply omit it and increase the mirin by half a tablespoon.
To keep karaage crispy for a party or gathering, hold finished pieces on a wire rack in an oven set to 200°F (95°C). Do not stack or cover the chicken, as steam will soften the crust.
Storage: Refrigerate cooled karaage in an airtight container for up to 3 to 4 days. Reheat in an air fryer or oven at 375°F for 5 to 8 minutes to restore crispiness. Avoid microwaving if possible, as it softens the crust significantly.
Freezing: Freeze fully cooled karaage in a single layer first, then transfer to a freezer bag. Store for up to 1 month and reheat directly from frozen in a 375°F oven for 12 to 15 minutes.
