Place chicken in sealable food-safe bag. Set aside. Add all marinade ingredients to small bowl. Whisk vigorously until ingredients are fully incorporated.
Pour marinade over chicken in bag. Seal bag, pressing out as much air as possible, then gently massage marinade into chicken through bag for 1 to 2 minutes. Place bag in refrigerator and let chicken marinate at least 2 hours, and no more than 12 hours.
Preheat grill to medium-high heat, approximately 375° to 450° Fahrenheit. When grill is hot, remove chicken from marinade and place directly on grill grates, over indirect heat.
Grill, with lid open, 6 to 8 minutes, or until golden. Flip chicken over and grill another 6 to 7 minutes or until chicken reaches internal temperature of 160° Fahrenheit according to internal meat thermometer.
Remove chicken from grill and place on cutting board to rest. After 5 minutes, slice chicken and serve warm with desired sides.
Recipe Notes
If your chicken pieces are very thick or if they're just drastically different thicknesses, I recommend tenderizing the chicken first so everything will cook evenly.
Cook times will vary depending on the size and thickness of the chicken pieces. The cuts of chicken you're using will also affect the cook time. Use an internal meat thermometer to ensure the chicken reaches a food-safe temperature before serving.
Liquid Smoke: Most grocery stores will carry mesquite liquid smoke, but if you can't find it, hickory liquid smoke will work, too.
Make it Keto: Use Brown Swerve instead of brown sugar.
