Prep the chicken: Pat the chicken thighs dry with paper towels. Dry surfaces help the seasoning stick and the edges crisp.
Make the seasoning blend: In a small bowl, combine lemon zest, black pepper, salt, garlic, onion powder, oregano, and smoked paprika if using.
Marinate: Add the chicken to a large bowl.
Drizzle with olive oil and toss with the seasoning blend until each piece is coated. Add the juice of 1 lemon, toss again, and let sit for 15–30 minutes. If you have time, chill for up to 2 hours.
Choose your cooking method: You can roast, air-fry, or pan-sear.
All three give great results: Oven: Preheat to 425°F (220°C). Arrange thighs on a parchment-lined sheet pan, skin side up if using skin-on.
Air Fryer: Preheat to 380°F (193°C). Place thighs in a single layer in the basket.
Skillet: Use a large oven-safe skillet.
Heat a thin layer of oil over medium-high. Place chicken skin side down and sear 4–5 minutes until golden.
Cook until done: Oven: Roast 22–28 minutes for bone-in, 18–22 minutes for boneless, until internal temperature reaches 165°F (74°C).
Air Fryer: Cook 16–22 minutes depending on thickness, flipping halfway if boneless/skinless.
Skillet + Oven: After searing, flip skin side up, squeeze the second lemon over the chicken, and transfer to the oven at 400°F (204°C) for 12–18 minutes.
Rest and finish: Let the chicken rest 5 minutes to keep it juicy. Taste and add a pinch of salt or more pepper if needed.
Garnish with chopped parsley and serve with lemon wedges.
