Preheat & prep. Preheat oven to 425°F. Pat chicken thighs completely dry with paper towels, this is key for crispy skin. Season generously on all sides with garlic powder, onion powder, smoked paprika, thyme, red pepper flakes, salt, and black pepper.
2 pounds chicken thighs, 2 tablespoons oil, 2 teaspoons kosher salt, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1 teaspoon thyme, ½ teaspoon smoked paprika, ½ teaspoon red pepper flakes, ½ teaspoon black pepper
Sear the chicken (optional but recommended). Heat a skillet over medium-high heat with a drizzle of oil. Sear chicken thighs skin-side down for 3–4 minutes until the skin is golden and begins to crisp up. Remove from the pan and set aside.
Season vegetables & apples. Toss sweet potato, apples, red onion, and green beans with oil, salt, pepper, smoked paprika, red pepper flakes, and dried thyme. Spread everything on a large sheet pan in a single layer.
3 large apples, 12 ounces sweet potato, 8 ounces green beans, 1 large red onion, 2 tablespoons oil, 1 ½ teaspoons kosher salt, ½ teaspoon black pepper, ½ teaspoon smoked paprika, ½ teaspoon dried thyme, ¼ teaspoon red pepper flakes
Roast. Nestle the chicken thighs skin-side up on the sheet pan. Roast at 425°F for 20-25 minutes, until the chicken is almost cooked through.
Make the sauce. While the chicken roasts, melt butter in a small saucepan over medium heat. Add garlic and cook until fragrant, about 1 minute. Pour in apple cider and honey, followed by the thyme sprigs. simmer until reduced by about half, 8–10 minutes.
3 tablespoons butter, 6-8 cloves garlic, 1 cup apple cider, 4 tablespoons honey, 6 sprigs thyme
Finish sauce. Remove from the heat, then discard the thyme sprigs. Stir in Dijon mustard, red pepper flakes, apple cider vinegar, and season to taste with salt and pepper.
1 tablespoon Dijon mustard, ½ teaspoon red pepper flakes, 1 tablespoon apple cider vinegar, ¼ teaspoon kosher salt, ¼ teaspoon black pepper
Glaze & finish roasting. Remove the pan from the oven. Spoon or brush the sauce generously over the chicken, apples, and vegetables. Return to the oven for 10–15 minutes, until the chicken reaches an internal temperature of 195°F and the glaze is sticky and caramelized.
Rest & serve. Let the pan rest for 5 minutes. Drizzle any remaining sauce over the top. Finish with fresh parsley and thyme.
