Korean Sweet and Sour Chicken Recipe: Crispy Bites With Tangy Glaze

This recipe delivers crispy chicken pieces coated in a perfectly balanced sweet and tangy glaze. The secret lies in the double-frying technique that ensures a shatteringly crisp exterior while keeping the meat juicy inside.

Traditional Korean flavors shine through in the sauce, which combines vinegar, sugar, and a touch of soy for depth. The result is a dish that’s both addictive and authentic.

Ingredients for Korean Sweet and Sour Chicken

Crispy chicken meets sweet-tangy Korean glaze with these simple ingredients.

The chicken is key here. Thighs stay juicier than breasts—look for skinless, boneless pieces with good marbling. Asian markets often have pre-cut chicken for stir-frying, which saves time. For the oil, any neutral variety with a high smoke point works; peanut oil is traditional but vegetable or canola oil are fine substitutes (and more affordable).

No rice vinegar? Apple cider vinegar at 1:1 ratio works in a pinch. Short on gochujang? Sriracha plus a pinch of sugar gets you close, though the flavor profile won’t be identical. The ketchup might seem unusual, but it’s crucial for that classic Korean sweet and sour balance—don’t skip it. For extra depth, add a splash of pineapple juice to the sauce.

Leftovers keep well in the fridge for 3-4 days but lose crispiness. Reheat in a toaster oven or air fryer to revive the crunch. Sauce can be made ahead and stored separately for up to 1 week.

Step-by-Step Instructions for Korean Sweet and Sour Chicken

Achieve perfectly crispy chicken with a glossy, tangy glaze using this tested method.

Step 1: Coat and Fry the Chicken

Pat the 1.5 lb boneless skinless chicken thighs dry with paper towels, then season with 1 tsp salt and 0.5 tsp black pepper. Cut into bite-sized pieces for even cooking. This step removes excess moisture so the coating adheres properly.

Dredge each piece first in 0.5 cup all-purpose flour, shaking off excess, then coat thoroughly in 0.5 cup cornstarch. The double coating creates an ultra-crispy exterior that holds up to the sauce. Heat 3 cups vegetable oil to 350°F in a deep pan.

Fry the chicken in batches for 4-5 minutes until golden brown and crispy. Use a slotted spoon to transfer to a paper towel-lined plate. Maintain the oil temperature between batches—if it drops too low, the chicken will absorb oil and become greasy.

Step 2: Prepare the Sweet and Sour Sauce

In a saucepan, combine 0.33 cup rice vinegar, 0.5 cup granulated sugar, 0.25 cup soy sauce, 0.25 cup ketchup, 1 tbsp gochujang, 4 cloves minced garlic cloves, and 1 tbsp grated fresh ginger. The vinegar provides the signature tang, while the sugar and ketchup balance it with sweetness.

Bring the mixture to a simmer over medium heat, stirring constantly until the sugar dissolves and the sauce thickens slightly, about 3-4 minutes. Watch for small bubbles around the edges—that’s your signal it’s ready. The sauce should coat the back of a spoon but still be pourable.

Step 3: Combine and Garnish

Add the crispy chicken to the saucepan and gently toss to coat evenly. Cook for an additional 1-2 minutes to allow the flavors to meld and the chicken to absorb some of the glaze. Avoid over-stirring at this point to preserve the crispy coating.

Transfer to a serving dish and garnish with 3 whole thinly sliced green onions and 1 tbsp toasted sesame seeds. The green onions add freshness, while the sesame seeds contribute a nutty crunch. Serve immediately while the chicken is still crispy and the sauce is glossy.
