How to Make Sweet and Sour Chicken

Marinate the chicken by mixing it with garlic, ginger, sake, salt, and pepper. Let it sit for 15 minutes to absorb the flavor.

In a separate bowl, combine white vinegar, water, soy sauce, sugar, sake, and chicken bouillon. Mix well and set aside.

Dredge the marinated chicken thoroughly in potato starch until evenly coated.

Heat oil to 350°F (175°C). Deep fry the chicken until golden brown and crispy, then drain on a paper towel.

In a pan over medium heat, pour in the prepared sauce and bring it to a simmer. Stir in the potato starch slurry and cook until the sauce thickens and becomes glossy.

Add the crispy chicken to the sauce and toss until evenly coated. Serve hot over steamed rice.

What Is Gochujang?

Gochujang is a Korean fermented chili paste made from red chili powder, fermented soybeans, glutinous rice, and salt. It has a deep umami flavor with a balance of sweet, savory, and spicy notes.

While this sweet and sour chicken does not traditionally use gochujang, a small spoonful can be added to the sauce if you want a spicy, Korean-inspired twist. It adds depth and gentle heat without overpowering the dish.

Tips for the Best Sweet and Sour Chicken

Chicken thighs are ideal because they stay juicy during frying. Potato starch creates a lighter, crispier coating than flour or cornstarch. Make sure the oil is fully heated before frying to prevent soggy chicken. Toss the chicken in the sauce just before serving to keep it crispy.

Serving Suggestions

Serve this sweet and sour chicken over steamed white rice or jasmine rice. It also pairs well with simple sautéed vegetables or a crisp cucumber salad to balance the richness.

Frequently Asked Questions

Q: Can I use chicken breast instead of thighs?
A: Yes, but chicken thighs are recommended because they remain juicier. If using chicken breast, be careful not to overcook.

Q: Can I make this dish less sweet?
A: Absolutely. You can reduce the sugar slightly and add a touch more vinegar for a sharper flavor.

Q: Can I bake or air fry the chicken instead of deep frying?
A: Deep frying gives the crispiest result, but you can air fry or bake the chicken. The texture will be slightly different but still delicious.

Q: Does this recipe use gochujang?
A: This version does not use gochujang, but you can add a small amount to the sauce if you want a spicy, Korean-inspired variation.

Q: How do I keep the chicken crispy?
A: Fry the chicken at the correct oil temperature and toss it in the sauce right before serving to maintain crispiness.

Q: How should leftovers be stored?
A: Store leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently, though the coating will soften.
