All ingredients ready? Let's begin!
Remove the chicken thighs from the refrigerator and the packaging. Give them a quick rinse under cool water. Pat completely dry with paper towels. Set the chicken aside on a clean plate to allow the thighs to come to room temperature.
In a small mixing bowl, whisk together the sugar, salt, coffee, pepper, paprika, onion powder, garlic powder, and cayenne.
Line a rimmed baking sheet with parchment paper. Preheat your oven to 400°F.
Drizzle or brush the olive oil on the chicken thighs. Then, pat the dry rub all over the thighs using your hands.
Generously rub the chicken with a mix of sugar, salt, coffee, pepper, paprika, onion powder, garlic powder, and cayenne, ensuring the blend covers every part evenly.
Place the chicken thighs on the lined baking sheet, skin side facing up.
Put the pan in the oven and roast the chicken until it reaches an internal temperature of 165°F when checked with an instant-read meat thermometer and the skin is crispy, approximately 35 to 40 minutes.
Transfer the thighs to a serving platter and pour the pan juices over them. Tent loosely with foil and allow the thighs to rest for 5 minutes before serving.
Serve the chicken with your favorite side dishes.
