Preheat oven to 400°F (200°C). Grease a large baking sheet or oven-safe skillet lightly with olive oil.
Prepare the chicken and potatoes:
In a large bowl, toss potatoes with 1 tablespoon olive oil, half the garlic, paprika, thyme, salt, and pepper. Spread potatoes on the baking sheet.
Season the chicken:
Rub chicken thighs with the remaining olive oil, garlic, paprika, salt, pepper, and onion powder. Nestle chicken among the potatoes on the baking sheet.
Bake:
Roast in the preheated oven for 35–45 minutes, until the chicken reaches an internal temperature of 165°F (74°C) and the potatoes are golden and tender. Halfway through, stir the potatoes and spoon some pan juices over the chicken for extra flavor.
Garnish and serve:
Sprinkle with fresh parsley and serve with lemon wedges for brightness.
