Chinese Sweet and Sour Chicken

Bright, tangy, and irresistibly saucy — this Chinese Sweet and Sour Chicken is the kind of weeknight dinner that feels like takeout but comes together in your own kitchen. Crispy-edged chicken bites are coated in a glossy, vibrant sauce made from pineapple juice, vinegar, ketchup, and a touch of brown sugar. Add colorful bell peppers and juicy pineapple chunks, and you have a plate that’s equal parts comforting and celebratory.

What I love about this version is how simple the technique is: a light batter made with just an egg white and cornstarch crisps up the chicken without heavy frying. The sauce reduces quickly on the stovetop, clinging to every piece so each bite has the perfect balance of sweet, sour, and a hint of heat. I’ve kept the ingredient list tight and pantry-friendly so this can be one of those repeat dinners you actually look forward to making.

Ingredients

• 1 large egg white
• 2 teaspoons cornstarch
• 1/2 teaspoons salt, divided
• 1 pound boneless, skinless chicken breasts or thighs, cut into 1-inch chunks
• 8-10 ounces pineapple chunks in juice (reserve the juice)
• 1 teaspoon fresh grated ginger
• 1/4 cup white vinegar
• 1/4 cup ketchup
• 2-3 tablespoons brown sugar
• 1-2 pinches cayenne pepper (or more to taste — spicy!)
• 2 tablespoons high heat cooking oil, divided (ex. grapeseed, peanut oil)
• 1 red bell pepper, seeded and cut into 1-inch chunks
• 1 yellow bell pepper, seeded and cut into 1-inch chunks
• 1/2 tablespoons sliced green scallions for garnish (optional)

Notes Before You Begin

Use chicken breasts or thighs according to your preference; both work well. Cutting the chicken into uniform 1-inch chunks ensures even cooking. I recommend saving the pineapple juice from the can — that liquid becomes a key part of the sauce and brings natural sweetness and acidity.

Step-by-Step Instructions

1. Prep the chicken and dry mix

Pat the chicken pieces dry with paper towels so the coating adheres well. In a bowl, whisk together the egg white, cornstarch, and 1/4 teaspoon of the salt until smooth and frothy. Add the chicken pieces and toss until they are evenly coated with this light batter. Let them sit while you prepare the rest of the ingredients; this brief rest helps the coating cling to the meat.

2. Prepare the sauce components

Measure out the reserved pineapple juice from the can so you have about 3 tablespoons available. In a small bowl or measuring cup, whisk together the pineapple juice, grated ginger, white vinegar, ketchup, brown sugar, the remaining 1/4 teaspoon salt, and the cayenne pepper. Taste and adjust the sweetness or heat: add the third tablespoon of brown sugar for a sweeter profile, or increase the cayenne for more kick. This sauce blend will be poured into the pan later and will thicken quickly.

3. Cook the chicken

Heat 1 tablespoon of high heat oil in a large skillet or wok over medium-high heat until shimmering but not smoking. Add the coated chicken pieces in a single layer, working in batches if necessary to avoid crowding. Let the chicken sear without stirring for about 2 minutes to develop a golden edge, then flip pieces and cook for another 2 minutes until mostly cooked through. Transfer the cooked chicken to a plate and set aside. Add the second tablespoon of oil if you need it before cooking the next batch.

4. Quick sauté of peppers and pineapple

With the pan still hot, add the red and yellow bell pepper chunks. Stir-fry the peppers for 2 to 3 minutes until they begin to become tender but still have crunch. Add the pineapple chunks and continue to cook for 1 additional minute, just long enough to warm the fruit and slightly caramelize the edges. This step ensures the vegetables and pineapple retain bright color and texture.

5. Combine sauce, chicken, and vegetables

Return the cooked chicken pieces to the skillet with the peppers and pineapple. Give the prepared sauce one last whisk and pour it over the skillet contents. Stir everything immediately to coat and bring the sauce to a gentle simmer. Let the mixture cook for 2 to 3 minutes, stirring occasionally, until the sauce has thickened and become glossy, clinging to the chicken and vegetables. If you prefer a slightly thicker sauce, let it reduce an extra minute; for a looser glaze, remove from heat earlier.

6. Finish and serve

Taste the finished dish and adjust seasoning if needed — add a small pinch of salt if it needs brightness, or an extra pinch of cayenne if you want more heat. Transfer the Chinese Sweet and Sour Chicken to a serving platter or bowls. Sprinkle the sliced green scallions over the top for a fresh, oniony finish if using. Serve immediately over steamed rice or alongside noodles so the glossy sauce can be soaked up.

Taste and Texture Tips

• If your sauce is too thin: let it simmer a bit longer uncovered until it reduces to your liking.
• If your sauce is too thick: stir in a tablespoon or two of water or reserved pineapple juice until you reach the desired consistency.
• To boost umami: a small splash of soy sauce (not included in the base recipe) can deepen the flavor, but add sparingly to keep the sweet-and-sour balance.
• For extra crispiness: after initial pan-searing, transfer the chicken to a wire rack in a single layer and keep warm in a low oven while you cook the peppers; this preserves the crisp exterior.

Make-Ahead and Storage

You can prepare the sauce and chop the vegetables ahead of time. Keep the chicken coated in the egg-white mixture refrigerated for up to 1 hour before cooking. Once cooked, store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over medium-low heat, adding a splash of water if the sauce has thickened too much. Reheated chicken will be best when eaten the same day it’s heated through.

Serving Suggestions

This Chinese Sweet and Sour Chicken pairs beautifully with steamed jasmine or basmati rice, which soaks up the saucy goodness. For a lower-carb option, serve over cauliflower rice or a bed of wilted bok choy. A side of steamed green beans or a crisp cucumber salad keeps the meal bright and balanced.

Why This Version Works

The combination of egg white and cornstarch creates a delicate coating that crisps quickly without requiring a heavy batter. Using the pineapple juice in the sauce brings natural sweetness and complexity, while ketchup provides tomato depth and body. White vinegar supplies the sharp counterpoint every sweet-and-sour sauce needs, and a small kiss of cayenne adds lift without overpowering the dish. The result is a vibrant, balanced plate that hits multiple flavor notes with minimal fuss.

Common Questions

Can I bake the chicken instead of frying? You can bake the coated chicken at 425°F for 10–12 minutes, flipping halfway through, to develop crisp edges. Then toss with the sauce on the stovetop to finish. Baking will yield a slightly different texture but less oil usage.

Can I use frozen pineapple? Yes. Thaw and drain well, reserving a small amount of pineapple juice if possible to mimic the can-stored juice called for in the recipe.

What if I don’t have fresh ginger? Substitute 1/4 teaspoon ground ginger, but fresh grated ginger will always offer brighter flavor.

• 1 yellow bell pepper, seeded and cut into 1-inch chunks
• 1/2 tablespoons sliced green scallions for garnish (optional)

Directions

1. Pat chicken dry. In a bowl, whisk the egg white, cornstarch, and 1/4 teaspoon salt until smooth. Add chicken and toss to coat; let rest briefly.
2. Reserve about 3 tablespoons of the pineapple can juice. In a small bowl, whisk the reserved juice with the grated ginger, white vinegar, ketchup, brown sugar, remaining 1/4 teaspoon salt, and cayenne pepper. Adjust sweetness or heat to taste.
3. Heat 1 tablespoon of oil in a large skillet or wok over medium-high heat. Add coated chicken in a single layer and cook 2 minutes without stirring, then flip and cook about 2 more minutes until mostly cooked. Transfer chicken to a plate; add remaining oil and repeat with any remaining chicken if needed.
4. Add the red and yellow bell pepper chunks to the hot skillet and stir-fry 2–3 minutes until beginning to soften. Add pineapple chunks and cook 1 more minute to warm and slightly caramelize them.
5. Return chicken to the skillet with the peppers and pineapple. Pour the prepared sauce over everything, stir to combine, and bring to a gentle simmer. Cook 2–3 minutes, stirring occasionally, until the sauce thickens and becomes glossy and coats the chicken and vegetables.
6. Taste and adjust seasoning as needed. Remove from heat, garnish with sliced green scallions if desired, and serve immediately over rice or noodles.
