Ingredients

Chicken Coating

  • 1 ½ pounds chicken breast, cut into bite-sized pieces
  • 2 large eggs, beaten
  • 1 cup cornstarch
  • ½ teaspoon salt
  • ¼ teaspoon black pepper

Sweet and Sour Sauce

  • ½ cup ketchup
  • ¼ cup rice vinegar
  • ¼ cup brown sugar
  • 2 tablespoons soy sauce
  • 1 teaspoon garlic, minced
  • 1 teaspoon cornstarch mixed with 2 tablespoons water (slurry)

Vegetables & Garnish

  • 1 red bell pepper, diced
  • 1 green bell pepper, diced
  • 1 cup pineapple chunks (fresh or canned, drained)
  • 2 green onions, chopped (for garnish)
  • Sesame seeds (optional)

Instructions

1. Preheat Oven

Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper or a lightly greased wire rack.

2. Prepare Chicken

Season chicken pieces with salt and pepper. Dip each piece in beaten eggs, then coat evenly with cornstarch.

3. Bake Chicken

Arrange the coated chicken on the prepared baking sheet. Bake for 20–25 minutes, flipping halfway through, until golden and crispy.

4. Make the Sweet and Sour Sauce

While chicken bakes, combine ketchup, rice vinegar, brown sugar, soy sauce, and minced garlic in a saucepan over medium heat. Bring to a gentle boil.

5. Thicken the Sauce

Add the cornstarch slurry to the sauce, stirring constantly until thickened. Remove from heat.

6. Prepare Vegetables

Dice bell peppers and pineapple. For a softer texture, you can lightly sauté the peppers in a pan for 2–3 minutes, or leave raw for crispiness.

7. Combine Chicken and Sauce

Once chicken is baked, transfer it to a large bowl. Pour the sweet and sour sauce over the chicken, then add bell peppers and pineapple. Toss to coat evenly.

8. Serve and Garnish

Transfer to a serving platter, garnish with chopped green onions and sesame seeds if desired. Serve hot with steamed rice or noodles.


Tips for Perfect Baked Sweet and Sour Chicken

Use a Wire Rack

Baking chicken on a wire rack allows hot air to circulate, keeping it crispy.

Don’t Overcrowd

Give chicken pieces space on the baking sheet to ensure even crisping.

Sauce Temperature

Pour sauce over hot chicken just before serving to maintain crispiness.

Make Ahead

Chicken can be baked ahead of time and reheated; add sauce just before serving.


Variations to Try

Spicy Sweet and Sour

Add ½ teaspoon chili flakes or sriracha to the sauce for a kick.

Honey Pineapple Version

Replace brown sugar with honey for a milder sweetness.

Mixed Vegetable Twist

Include carrots, snap peas, or baby corn for extra color and nutrition.

Gluten-Free Option

Use gluten-free cornstarch and tamari instead of soy sauce.


What to Serve with Sweet and Sour Chicken

  • Steamed Jasmine Rice – Perfect to soak up the sauce.
  • Fried Rice – Adds a flavor-packed side.
  • Stir-Fried Vegetables – For an extra nutrient boost.
  • Noodles – Tossed with sauce for a noodle bowl variation.

Storage and Reheating

Refrigerator

Store leftover chicken in an airtight container for up to 3 days.

Freezer

Chicken can be frozen before tossing with sauce for up to 1 month.

Reheating

Reheat in the oven at 350°F (175°C) for 10 minutes to retain crispiness, or in a skillet over medium heat with a splash of water.


Fun Fact

Sweet and sour chicken is inspired by Chinese cuisine, traditionally using deep-fried chicken coated in a tangy sauce. The oven-baked version preserves flavor while reducing oil, making it a modern, healthier twist on a classic favorite.
