In a medium saucepan, combine the soy sauce, brown sugar, rice vinegar, orange juice, garlic, ginger, and 1/3 cup water. Heat over medium-high heat until the mixture starts to bubble. Reduce heat to medium. In a small bowl combine 2 tablespoons water and cornstarch, stir until combined.
Add the cornstarch mixture into the sauce, whisk well and allow to simmer 5-10 minutes, stirring often until thick and reduced. If the sauce is to thick, thin with a little water.
For the chicken:
In a small bowl combine the flour, salt, garlic powder, paprika, and black pepper. Stir to combine. Toss the cubed chicken in the flour mixture to evenly coat*.
Preheat air fryer to 400 degrees for 12-15 minutes. Once preheated, add the chicken into the air fryer basket in a single layer*. Air fry for 14-16 minutes, flipping halfway through. Chicken is done when it has an internal temperature of 165 degrees F. Transfer cooked chicken to a large mixing bowl, top with the sauce, and toss to combine.
Serve over steamed rice. Leftover chicken will keep in an airtight container in the fridge for 2-3 days.
Notes
*You can also toss the chicken in a large gallon bag for even coating and less mess.*Chicken needs to cook in a single layer in order to get crispy. If needed, cook in batches and keep warm in a 250 degree oven.*Leftover orange chicken is best reheated in the air fryer or oven
