Ingredients:
- 3 tablespoons cane or white vinegar (you can also use rice vinegar or apple cider vinegar if that’s what you have on hand)
- 1/4 cup ketchup
- 1/4 cup granulated sugar
- 1/2 cup water
- 1/4 teaspoon red pepper flakes (this is optional, but adds a lovely little kick if you like a bit of heat)
- 1 tablespoon soy sauce
- 2 teaspoons cornstarch (for the sauce)
- 12 ounces boneless, skinless chicken thighs or breasts, cut into roughly 1-inch pieces. Thighs tend to stay more moist and tender, but breasts work beautifully too!
- 1 egg white, lightly beaten
- 1/4 cup all-purpose flour
- 1/4 cup cornstarch (for coating the chicken)
- 1 teaspoon baking powder
- Salt and freshly ground black pepper, to taste
- 1 medium white or yellow onion, cut into 1-inch pieces. A yellow onion will give a slightly sweeter flavor than white.
- 1/2 red bell pepper (this should be about 1 cup once chopped), cut into 1-inch pieces. The red bell pepper adds beautiful color and a hint of sweetness.
Preparing the Sweet and Sour Sauce
Let’s start by getting our vibrant sweet and sour sauce ready. This is where all that delicious tangy and sweet flavor comes from. In a small saucepan, combine the vinegar, ketchup, sugar, water, and soy sauce. If you’re using the red pepper flakes for a touch of heat, add them now as well. Stir everything together well to ensure the sugar begin extracts to dissolve. Place the saucepan over medium heat and bring the mixture to a gentle simmer. Allow it to simmer for about 5 minutes, stirring occasionally, to let the flavors meld together. While the sauce is simmering, in a small bowl, whisk together the 2 teaspoons of cornstarch with 1 tablespoon of cold water. This creates a slurry, which will be used to thicken our sauce. Once the sauce has simmered for 5 minutes, slowly whisk in the cornstarch slurry. Continue to cook, stirring constantly, for another 1-2 minutes, or until the sauce has thickened to your desired consistency. It should be glossy and coat the back of a spoon nicely. Remove the sauce from the heat and set it aside. You can cover it to keep it warm while you prepare the chicken and vegetables.
Coating and Frying the Chicken
Now, let’s get the chicken ready for its crispy transformation! In a medium bowl, combine the 1/4 cup all-purpose flour, 1/4 cup cornstarch, baking powder, and a generous pinch of salt and pepper. Whisk these dry ingredients together until they are well combined. In a separate shallow dish, pour the lightly beaten egg white. Take your cut chicken pieces and first dip them into the egg white, ensuring each piece is lightly coated. Let any excess egg white drip off. Then, immediately transfer the egg-white-coated chicken pieces into the flour and cornstarch mixture. Toss them gently until each piece is thoroughly coated. The cornstarch and baking powder in the coating will help create an extra crispy exterior when fried.
Next, we’ll fry the chicken. You’ll need a frying pan or a wok for this. Add about 1 to 1.5 inches of a neutral cooking oil (like vegetable, canola, or peanut oil) to your pan. Heat the oil over medium-high heat until it reaches about 350-360°F (175-180°C). You can test if the oil is hot enough by dropping a tiny piece of the coated chicken into it; it should sizzle immediately and float to the surface. Carefully add the coated chicken pieces to the hot oil in batches, making sure not to overcrowd the pan. Overcrowding will lower the oil temperature and result in soggy chicken. Fry the chicken for about 4-5 minutes per batch, turning them occasionally, until they are golden brown and cooked through. Use a slotted spoon or spider strainer to remove the crispy chicken from the oil and place them on a wire rack set over a baking sheet. This allows any excess oil to drain off, keeping them wonderfully crisp.
Sautéing the Vegetables
While the chicken is frying or resting, it’s time to quickly cook our colorful vegetables. In the same pan you used for the chicken (or a clean wok/large skillet if you prefer), add about 1 tablespoon of the cooking oil used for frying, or a fresh tablespoon of oil. Heat it over medium-high heat. Add the chopped onion and red bell pepper to the hot pan. Sauté the vegetables for about 3-4 minutes, stirring frequently, until they are slightly tender but still have a bit of a crisp bite. We don’t want them to become mushy; they should still have some texture.
Combining Everything for the Final Dish
Once the vegetables are tender-crisp, it’s time to bring it all together. Pour your prepared sweet and sour sauce over the sautéed vegetables in the pan. Stir everything together to coat the vegetables evenly with the sauce. Let the sauce come back to a gentle simmer. Now, carefully add the fried, crispy chicken pieces to the pan with the vegetables and sauce. Gently toss everything together, ensuring that each piece of chicken is coated in the delicious sweet and sour sauce. Cook for just another 1-2 minutes, allowing the chicken to heat through and absorb some of the sauce’s flavor without losing its crispiness. Be careful not to overcook at this stage, as the chicken can become soft if left in the sauce for too long.
Serving Your Sweet and Sour Chicken
Your incredible homemade Sweet and Sour Chicken is now ready to be enjoyed! Serve it immediately while it’s hot and the chicken is still wonderfully crispy.

Frequently Asked Questions:
Can I make the sauce ahead of time?
Absolutely! The sweet and sour sauce can be made a day or two in advance and stored in an airtight container in the refrigerator. This can save you time when you’re ready to prepare the dish. Just reheat it gently on the stovetop before tossing with the cooked chicken and vegetables.
What if I don’t have rice vinegar?
If you’re out of rice vinegar, you can substitute it with white grape juice vinegar or even apple cider vinegar. The flavor profile might shift slightly, but it will still create a wonderfully tangy sauce. You might need to adjust the sugar slightly depending on the acidity of your substitute.
