Ingredients
  

  • 1 pound boneless, skinless chicken breast cut into 1-inch cubes
  • 1/2 cup cornstarch
  • 1 teaspoon kosher salt
  • 1/2 teaspoon white pepper
  • 1 large egg beaten
  • olive oil spray
  • 1/4 cup pineapple juice fresh or canned
  • 3 tablespoons rice vinegar
  • 3 tablespoons brown sugar
  • 2 tablespoons ketchup
  • 1 tablespoon soy sauce
  • 1 teaspoon sesame oil
  • 1 teaspoon fresh ginger grated
  • 1 clove garlic minced
  • 1 tablespoon cornstarch dissolved in 2 tablespoons water
  • 1 red bell pepper cut into 1-inch pieces
  • 1 green bell pepper cut into 1-inch pieces
  • 1/2 cup pineapple chunks fresh or canned, drained
  • 1/2 medium onion cut into 1-inch pieces

Method
 

  1. Pat chicken breast pieces dry with paper towels to remove excess moisture.
  2. In a shallow bowl, combine cornstarch, salt, and white pepper.
  3. Place beaten egg in a separate bowl. Dip chicken pieces first in egg, then coat in cornstarch mixture.
  4. Let coated chicken rest for 5 minutes to help coating adhere.
  5. Preheat air fryer to 380°F for 3 minutes.
  6. Lightly spray air fryer basket with olive oil. Arrange chicken in a single layer and spray tops lightly with oil.
  7. Cook chicken for 10 minutes at 380°F, shaking basket halfway through. Chicken should reach 165°F internal temperature.
  8. While chicken cooks, combine pineapple juice, rice vinegar, brown sugar, ketchup, soy sauce, sesame oil, ginger, and garlic in a small saucepan.
  9. Bring sauce to a gentle simmer over medium heat. Whisk in cornstarch slurry and simmer 2-3 minutes until thickened. Remove from heat.
  10. Place bell peppers, pineapple chunks and onion in air fryer basket. Air fry at 380°F for 4 minutes until slightly tender but still crisp.
  11. In a large bowl, combine cooked chicken with vegetables. Pour two-thirds of the sweet and sour sauce over mixture and toss to coat.
  12. Return sauced chicken and vegetables to air fryer. Cook at 380°F for 2 minutes to caramelize sauce.
  13. Serve immediately with remaining sauce on the side.

Note

  • For best results, cut chicken into uniform 1-inch pieces to ensure even cooking.
  • Don't skip the final 2-minute air frying step with the sauce - this caramelizes the sugars for better flavor.
  • Work in batches if your air fryer is small - overcrowding prevents proper crisping.
  • The sweet and sour sauce can be made up to 5 days ahead and stored in the refrigerator.
  • Verify chicken has reached 165°F internal temperature for food safety.
