Preheat the oven: Set to 425°F (220°C). A hot oven helps crisp the skin and lock in moisture.
Prep the pan: Line a sheet pan with foil or parchment for easy cleanup. Set a wire rack on top if you have one for better airflow and crisper skin.
Dry the chicken: Pat thighs very dry with paper towels. Dry skin = crisp skin.
Mix the seasoning: In a small bowl, combine ranch seasoning, garlic powder, onion powder, paprika, pepper, and salt.
Taste a pinch of the dry mix to gauge saltiness if your ranch blend is strong.
Coat with oil: Drizzle thighs with olive oil and rub to coat all sides. This helps the seasoning adhere and the skin crisp.
Season generously: Sprinkle the ranch mixture evenly on all sides, gently lifting the skin to tuck some seasoning underneath for deeper flavor.
Add optional butter: Brush a light layer of melted butter over the skin for extra browning and flavor.
Arrange on the pan: Place thighs skin-side up, spaced out so they’re not touching. Crowding leads to steaming, not crisping.
Bake: Roast for 30–40 minutes, depending on size.
You’re looking for an internal temperature of 175–190°F in the thickest part. Thighs taste best a bit higher than the standard 165°F—they get more tender.
Optional broil: For extra crispy skin, broil the last 2–3 minutes, watching closely.
Rest and garnish: Let the chicken rest for 5 minutes. Sprinkle with chopped parsley or chives.
Serve with lemon wedges for a bright finish.
