If you’ve ever wanted a restaurant-style Sweet and Sour Chicken that crisps up perfectly at home and has a glossy, tangy-sweet sauce that clings to every bite, you’re in the right place. This version uses simple pantry staples and fresh bell peppers and pineapple for bright flavor. The chicken is dredged, fried, and tossed in a vibrant sauce that balances sweet, tangy, and savory notes. It’s approachable, family-friendly, and makes great leftovers.

Why this recipe works

This Sweet and Sour Chicken is all about contrast: crunchy fried coating versus juicy chicken, and sweet pineapple versus tangy vinegar. The dredge of cornstarch and flour gives a light, crisp exterior, and the double-sweetener in the sauce (granulated and packed light brown sugar) deepens the flavor. A small cornstarch slurry at the end yields a glossy, clingy sauce that makes every forkful irresistible.

Ingredients

¾–1 cup canola oil, for frying
½ cup cornstarch
3–4 chicken breasts or chicken thighs, cut into 1-inch pieces
2 eggs, beaten
½ cup all-purpose flour, plus more if needed
1 red bell pepper, cut into 1-inch chunks
1 green bell pepper, cut into 1-inch chunks
1 cup pineapple chunks
¾ cup water
⅓ cup pineapple juice
⅓ cup distilled white vinegar
⅓ cup soy sauce
⅓ cup ketchup
½ cup sugar
¼ cup packed light brown sugar
⅛ teaspoon salt
3 tablespoons cornstarch mixed with ¼ cup water (slurry)

Notes on ingredients

The recipe calls for either chicken breasts or chicken thighs cut into 1-inch pieces. Choose breasts for a leaner bite or thighs for a richer, juicier result. The dredge uses both cornstarch and all-purpose flour — the cornstarch creates crispiness while the flour helps the coating adhere. The sauce is balanced with pineapple juice and distilled white vinegar for a bright tang, while two sugars create depth. Reserve the cornstarch slurry until the end so you can thicken the sauce quickly and evenly.

Equipment

Large skillet or wok for frying
Deep-sided pan or pot if you prefer deeper frying
Mixing bowls for dredging and eggs
Measuring cups and spoons
Tongs or slotted spoon
Paper towels and a wire rack or plate for draining
Saucepan for making the sweet and sour sauce

Step-by-step Instructions

Follow these steps in order to get perfectly cooked chicken pieces coated in a glossy sweet and sour sauce. The directions below preserve the original ingredient amounts and order but rewrite the method into clear, practical steps.

Prepare your workspace and ingredients. Cut 3–4 chicken breasts or thighs into 1-inch pieces. Chop 1 red and 1 green bell pepper into 1-inch chunks. Measure out ½ cup cornstarch, ½ cup all-purpose flour, and beat 2 eggs in a shallow bowl. Drain 1 cup pineapple chunks if canned, reserving any extra juice only if you need it; use the specified ⅓ cup pineapple juice in the sauce. Have ¾–1 cup canola oil ready for frying.
Set up a dredging station. In one shallow dish, combine ½ cup cornstarch and ½ cup all-purpose flour. Add a pinch of the ⅛ teaspoon salt to the dry mixture. In a second shallow dish, beat the 2 eggs until smooth. You’ll be dipping each chicken piece first into the egg, then into the flour-cornstarch blend.
Coat the chicken. Working in batches to avoid crowding, dip each 1-inch chicken piece into the beaten eggs, letting excess drip off, then dredge thoroughly in the cornstarch–flour mixture so each piece is evenly coated. Place coated pieces on a plate while you warm the oil. If the coating seems too wet or thin, sprinkle a little more all-purpose flour into the dry mixture and toss the pieces lightly to get a better coating.
Heat the oil and fry the chicken. Pour ¾–1 cup canola oil into a large skillet or wok and heat over medium-high heat until shimmering. Test the oil carefully with a small piece of coating — it should sizzle immediately. Fry the chicken pieces in a single layer without crowding, turning occasionally so each piece turns golden and crisp on all sides. Depending on the thickness, fry until the chicken registers 165°F internally and the coating is golden, about 4–6 minutes per batch. Remove fried chicken to a wire rack or a plate lined with paper towels to drain. Repeat until all chicken is cooked.
Sauté the vegetables and pineapple. In a clean skillet or the same pan after wiping excess oil, add a tablespoon of oil over medium heat. Add the 1-inch chunks of red and green bell pepper and cook for about 2–3 minutes until they begin to soften but remain bright and slightly crisp. Add 1 cup pineapple chunks and toss to heat through, about 1–2 minutes. Remove the peppers and pineapple from the pan and set aside.
Make the sweet and sour sauce. In a medium saucepan, combine ¾ cup water, ⅓ cup pineapple juice, ⅓ cup distilled white vinegar, ⅓ cup soy sauce, ⅓ cup ketchup, ½ cup sugar, ¼ cup packed light brown sugar, and ⅛ teaspoon salt. Warm the sauce over medium heat, stirring occasionally until the sugars dissolve and the mixture begins to simmer gently.
Thicken the sauce. Once the sauce is simmering, stir the prepared cornstarch slurry (3 tablespoons cornstarch mixed with ¼ cup water) to recombine, then slowly whisk it into the simmering sauce. Continue to cook and whisk for 1–2 minutes until the sauce thickens to a glossy, slightly viscous consistency that coats the back of a spoon. If the sauce becomes too thick, add a splash of water to loosen it; if it’s too thin, mix a tiny extra amount of cornstarch with water and whisk in sparingly.
Combine chicken, veggies, and sauce. Return the fried chicken pieces to the skillet or pan, then add the sautéed bell peppers and pineapple. Pour the thickened sauce over everything and gently toss or stir to coat each piece evenly. Heat for another 1–2 minutes to warm the chicken and let the flavors marry.
Serve immediately. Transfer the Sweet and Sour Chicken to a serving platter and serve hot over steamed rice or alongside your favorite noodles. Garnish with chopped green onions or sesame seeds if you like. Leftovers keep well refrigerated in an airtight container for 2–3 days; gently reheat in a skillet to preserve the sauce and coating texture.

Troubleshooting tips

If the coating falls off the chicken during frying: be sure each piece is fully dry before dipping in egg and that you press the dry mix onto the surface evenly. Avoid overcrowding the pan so the oil temperature stays steady.
If the sauce is too thin: add your cornstarch slurry in very small increments, whisking constantly until the desired thickness is reached.
If the oil smokes: lower the heat and remove the pan from the burner briefly. Use a thermometer if you have one; ideal frying oil temperature is around 350–375°F.
Prefer a lighter fry: shallow-fry with less oil or bake the coated pieces at 425°F on a wire rack until crisp, then toss with the sauce at the end.

Serving suggestions

Sweet and Sour Chicken is wonderful served over steamed white or jasmine rice, but it’s also great on brown rice, cauliflower rice, or tossed with noodles. Add a side of steamed broccoli, snap peas, or a simple cucumber salad to round out the meal. For a faster weeknight version, lightly stir-fry the vegetables while the chicken fries so everything finishes at the same time.

Storage and make-ahead

Refrigerate leftovers in an airtight container for up to 3 days. To reheat, warm gently in a skillet with a splash of water or pineapple juice to revive the sauce and prevent the chicken from drying out. You can make the sauce ahead and store it separately for up to 3 days; reheat and toss with freshly fried or reheated chicken and vegetables.

Final notes

This Sweet and Sour Chicken delivers the classic sweet, tangy, and savory profile you crave with crispy fried chicken and vibrant vegetables. The method is straightforward: coat, fry, make the sauce, then toss everything together. It makes a beautiful family-style dinner and reheats well for quick lunches. With this clear, step-by-step approach, you’ll have glossy, delicious Sweet and Sour Chicken on your table with confidence.

Servings: 6 servings

Ingredients

3/4-1 cup canola oil for frying
1/2 cup cornstarch
3-4 chicken breasts or chicken thighs cut into 1-inch pieces
2 eggs beaten
1/2 cup all-purpose flour plus more if needed
1 red bell pepper cut into 1-inch chunks
1 green bell pepper cut into 1-inch chunks
1 cup pineapple chunks
3/4 cup water
1/3 cup pineapple juice
1/3 cup distilled white vinegar
1/3 cup soy sauce
1/3 cup ketchup
1/2 cup sugar
1/4 cup packed light brown sugar
1/8 teaspoon salt
3 tablespoons cornstarch mixed with 1/4 cup water (slurry)

Instructions

Prepare the sauce: combine 3/4 cup water, pineapple juice, vinegar, soy sauce, ketchup, both sugars, and salt in a medium saucepan; keep over low heat and stir occasionally while frying the chicken.
Heat 3/4 to 1 cup canola oil (about 1–1½ inches) in a large frying pan over medium-high heat until hot for frying.
Place 1/2 cup cornstarch in a large resealable plastic bag and add the chicken pieces; shake to coat evenly.
Beat 2 eggs in a bowl and place 1/2 cup all-purpose flour in a separate bowl. Dip each cornstarch-coated chicken piece into the beaten eggs, then dredge in flour to coat.
Fry the coated chicken in the hot oil for 2–3 minutes per piece, turning with tongs, until golden, crispy, and cooked through. Transfer to a paper towel–lined plate; reserve a few tablespoons of oil in the pan and discard the rest.
Add the red and green bell peppers and pineapple chunks to the pan with the reserved oil and cook for 1–2 minutes until peppers are crisp-tender.
Finish the sauce: whisk the cornstarch slurry (3 tablespoons cornstarch mixed with 1/4 cup water), add it to the simmering sauce, bring to a low boil, and cook, stirring, until thickened about 2 minutes.
Add the thickened sauce to the pan with peppers and pineapple, then return the fried chicken to the pan and stir to coat evenly; cook until sauce is bubbling, about 4–5 minutes.

Notes

Try adding other vegetables like onions, shredded carrots, broccoli, or mushrooms for variation.
You can prepare the dish a day ahead and refrigerate it until ready to reheat.
Boneless chicken thighs are a great alternative to chicken breasts.
For a lighter version, skip the coating and pan-fry cubed chicken directly.
