01 - In a mixing bowl, whisk together maple syrup, bourbon, Dijon mustard, apple cider vinegar, minced garlic, smoked paprika, salt, and black pepper until fully blended.
02 - Place chicken thighs in a resealable bag or shallow dish. Pour half of the marinade over the chicken, reserving the rest. Refrigerate and marinate for at least 20 minutes, up to 2 hours for more flavor.
03 - Heat 2 tablespoons olive oil in a large skillet set over medium heat. Add diced sweet potatoes and cook for 5 minutes, stirring occasionally.
04 - Add diced red and green bell peppers, red onion, thyme, salt, and black pepper to the skillet. Continue cooking, stirring often, until sweet potatoes are tender and golden, about 10 to 12 minutes. Transfer the hash to a bowl and keep warm.
05 - Wipe out the skillet. Add 2 tablespoons olive oil and heat over medium-high. Remove chicken from marinade and discard the used marinade. Sear chicken thighs for 3 to 4 minutes on each side until browned.
06 - Reduce the heat to medium and pour the reserved marinade over the chicken. Cook, turning occasionally, until chicken is cooked through and the glaze is thickened and glossy, about 8 to 10 minutes. Add a splash of water if needed.
07 - Arrange the sweet potato hash on serving plates. Top with chicken thighs and spoon glaze over each. Sprinkle with chopped fresh parsley.
