Start by cutting the boneless skinless chicken breasts into bite-sized pieces, season with salt and pepper, and coat with cornstarch.

In a separate bowl, whisk together orange juice, soy sauce, lemon juice, brown sugar, cornstarch, orange zest, grated ginger, minced garlic, and optional crushed red pepper flakes.

Heat olive oil in a large skillet over medium-high heat, add half of the chicken pieces, and cook until golden brown and fully cooked.

Transfer the first batch to a plate and repeat the cooking process with the remaining chicken.

Pour the tangy orange sauce into the hot skillet and return the cooked chicken, tossing until coated.

Plate your Easy Orange Chicken and garnish with chopped scallions before serving.
