Step 1

Combine the orange zest, orange juice, soy sauce, brown sugar, apple cider vinegar, cornstarch, ginger, garlic and red pepper flakes in a small bowl. Whisk until well combined.

Step 2

In a large skillet, heat the oil over medium-high heat. Add the chicken pieces to the pan and season with salt and pepper. Let the chicken brown on the first side for a few minutes and then flip, and continue cooking, stirring occasionally, until cooked through. (This will take about 7-10 minutes, depending on the size of your chicken pieces. Thighs take a bit longer to cook through than chicken breasts.) If the pan gets too hot, reduce the heat to medium.

Step 3

Whisk the sauce again to make sure everything is well combined and then pour the sauce into the pan with the chicken. Cook, stirring, for 1-2 minutes, until the sauce thickens.

Step 4

Serve chicken and sauce over rice, topped with green onions and sesame seeds if desired.
