📖 Recipe

Sweet and sour chicken 咕嚕雞 (goo low gai) has a special place in my heart. I first ate it at a local Chinese restaurant as a little girl and instantly fell in love with the combination. I still remember trying to make it myself as a teen, and boy, was it an utter failure! That failed batch taught me the key to a balanced sweet and tangy sauce: use a strict 2:1 ratio of sugar to vinegar with ketchup.

I also found that evenly coating the chicken in cornstarch and letting the crust set before flipping makes it much crispier without needing a ton of oil.

Why It Works

Cornstarch crust: A dry cornstarch coating turns light and crisp without a wet batter and holds up well to the glaze.
Steady frying heat: A heavy-bottomed pan and small batches help maintain 350°F so the chicken fries crisp, not soggy.
Quick saucing: Coating the chicken right before serving limits how much sauce soaks into the crust.

Ingredients & Substitutes

Exact ingredient amounts are listed in the recipe card at the bottom of this page.

ingredients to make sweet and sour chicken

Chicken Thighs: Boneless, skinless thighs stay juicy during frying. Chicken breast also works, but will be leaner.
Red Bell Peppers: Red peppers are naturally sweeter, but green, orange, or yellow bell peppers also work.
Fresh Pineapple: Choose a ripe pineapple for the best sweetness. Well-drained canned or thawed frozen pineapple also works.
Onion: Slice into 1-cm-wide pieces so they cook evenly. Shallot works too.
Cornstarch: Creates the crispy coating. Potato starch works too, but avoid tapioca or arrowroot starch because the chicken can stick together.
Vegetable Oil: Use a neutral, high-smoke-point oil for frying. Canola or avocado oil also works.
Salt
Garlic Powder: Use powder instead of fresh minced garlic, which can burn during frying.
Toasted Sesame Seeds: Buy them toasted or toast raw sesame seeds in a dry pan until fragrant.
Green Onion

Sweet and Sour Sauce

Ketchup: I prefer Heinz for its classic flavor. Avoid artisanal ketchups, which can change the flavor of the sweet and sour sauce.
Brown Sugar: I prefer light brown sugar, but dark brown sugar works too.
Regular Soy Sauce: Light soy sauce also works, or use low-sodium soy sauce for a less salty result.
White Vinegar: Use this for a sharper tang. Rice vinegar or apple cider vinegar works for a milder tang.
Cold Water
Cornstarch: Thickens the sauce so it clings to the chicken. Potato or tapioca starch also works.

Note: Most Asian ingredients are typically found at Asian grocery stores, or you can check online.

Expert Tips

Press chicken into cornstarch to create craggy edges that fry extra crisp.
Shake off loose cornstarch so excess starch doesn't fall off and burn.
Fry coated chicken immediately before the cornstarch absorbs moisture and turns soggy.

Instructions

Below are step-by-step instructions on how to make sweet and sour chicken:

Sauce ingredients being mixed in a small bowl until the sugar is fully dissolved.

Make the sauce: Whisk together the listed sauce ingredients until the sugar dissolves. Set aside.

Diced chicken thighs in a bowl being seasoned with salt and garlic powder, then coated evenly with cornstarch.

Prepare the chicken: Dice the chicken thighs into even 1.5-inch pieces. Don't pat them dry; the natural surface moisture helps the cornstarch stick. Season with salt and garlic powder, then coat well with cornstarch. If any areas remain uncoated, add 1-2 tablespoons more cornstarch as needed.

Chicken pieces frying in hot oil in a pan until golden and crispy on both sides.

Fry the chicken: Heat the oil in a large, heavy-bottomed pan over medium-high heat to 350°F. Fry the chicken in small batches for 2.5-3.5 minutes per side, until golden and crispy with the thickest pieces reaching 165°F. Leave the chicken undisturbed until the crust sets before flipping. Between batches, remove any browned bits and let the oil return to 350°F.

Drain the chicken: Transfer the fried chicken to a wire rack to keep the crust crisp.

Chopped onions, red bell pepper, and pineapple sautéing in a pan, then sauce added and simmered until thickened.

Sauté vegetables and simmer sauce: Remove all but 1 teaspoon (5 ml) of oil from the pan. Reduce the heat to medium and sauté the onion, red bell pepper, and pineapple for 30-45 seconds. Whisk the sauce again, pour it in, and simmer for 30-45 seconds until thickened.

Fried chicken tossed in a thick, glossy sauce and garnished with green onions and sesame seeds before serving.

Toss and garnish: Add the fried chicken and toss until evenly coated in the sauce. Remove from the heat and garnish with green onions and sesame seeds.

Variations

Gluten-Free: Swap regular soy sauce with gluten-free soy sauce or tamari.
Vegetarian: Swap chicken with well-drained, patted-dry extra-firm tofu cubes. Season with salt and garlic powder, coat with cornstarch, then fry until golden and crispy.

Pairing Suggestions

White Rice: Plain rice balances the bold sweet and sour sauce.
Spicy Garlic Bok Choy: Garlicky greens add a spicy contrast to the sweet chicken.
Egg Rolls: Crispy egg rolls add a savory starter before the sweet and tangy chicken.

Storage & Reheating

Refrigerator: Store the chicken and sauce separately in airtight containers for up to 3 days when possible to keep the chicken crisp.
Freezer: Cool completely and freeze the chicken and sauce separately for up to 2 months; thaw overnight in the refrigerator.
Reheating: If stored separately, air fry chicken at 350°F for 5 minutes or bake at 400°F for 8 minutes, then toss with warmed sauce; if already sauced, bake at 400°F for about 12 minutes or air fry at 350°F for about 8 minutes.

FAQ

How do I keep sweet and sour chicken crispy?

Toss the crispy chicken with the warm sauce right before serving so the coating has less time to soften. For maximum crunch, keep the sauce separate and use it for dipping.

Why is my sweet and sour chicken not crispy?

Overcrowding, low oil temperature, and an uneven cornstarch coating can make the chicken soggy. Fry in small batches and let the coating set before moving the chicken.

Can I make sweet and sour chicken in the air fryer?

Yes. Lightly spray the air fryer basket with oil, then arrange the coated chicken in a single layer with space between each piece. Lightly spray the chicken with oil and air fry at 400°F for 10-14 minutes, without flipping, until golden and the thickest pieces reach 165°F. Toss with the cooked vegetables and sauce just before serving.
