Preheat oven to 425°F.
Cut potatoes into 1-inch wedges and toss with 1 tbsp olive oil, half the salt, and a pinch of oregano.
Pat chicken dry. Mix remaining oil, paprika, garlic powder, oregano, remaining salt, and pepper.
Coat drumsticks thoroughly in the spice mixture.
Spread potatoes on a large rimmed sheet pan. Nestle chicken among them.
Bake 35–40 minutes until chicken reaches 165°F and potatoes are tender.
Rest 5 minutes, then garnish with parsley and lemon juice.
Serve hot with pan juices spooned over the top.
Tip: For extra crisp skin, broil the last 2–3 minutes while watching closely.
