01 - Preheat oven to 400°F. Pat chicken thighs dry with paper towels. Season both sides generously with salt, black pepper, garlic powder, and smoked paprika, pressing spices into meat to adhere.
02 - Heat large oven-safe skillet over medium-high heat. Add oil swirl and sear chicken 2–3 minutes per side until deep golden brown crust forms. Transfer to plate and set aside.
03 - Reduce skillet heat to medium. Add butter and melt completely. Whisk in honey, soy sauce, minced garlic, apple cider vinegar, and Dijon mustard. Simmer 1–2 minutes until slightly thickened and fragrant.
04 - Return chicken thighs to skillet, turning each piece to coat thoroughly in the honey butter glaze. Arrange chicken skin-side up in single layer.
05 - Transfer skillet to preheated oven. Bake 20–25 minutes, basting chicken with pan juices once or twice during cooking, until internal temperature reaches 165°F and meat is cooked through.
06 - Remove from oven. Spoon remaining sauce over chicken. Garnish with chopped parsley and green onions if desired. Serve immediately alongside rice or steamed vegetables.
