Begin by cutting the boneless, skinless chicken thighs into bite-sized pieces. This will allow for even cooking and easy serving.
In a large mixing bowl, add the all-purpose flour. Toss the chicken pieces in the flour until they are well-coated. This step will help create a crispy exterior once cooked.
Heat a skillet or wok over medium-high heat. Add a splash of oil and then add the coated chicken pieces. Sear the chicken for about 5-7 minutes, or until golden brown and cooked through.
While the chicken is cooking, in a separate bowl, combine the honey barbecue sauce, orange marmalade, orange juice, low-sodium soy sauce, minced ginger, and crushed red pepper flakes. Whisk the ingredients together until smooth.
Once the chicken is fully cooked, reduce the heat to medium-low and pour the sauce over the chicken in the skillet. Stir well to coat all the pieces in the luscious sauce. Allow to simmer for about 5-10 minutes.
Just before serving, sprinkle the toasted sesame seeds over the chicken for added crunch and flavor.
Serve your Sesame Orange Chicken over a bed of rice or alongside steamed vegetables for a complete meal. Enjoy!
