Preheat oven to 400°F (200°C).
In a large bowl combine potatoes, olive oil, minced garlic, Italian seasoning, garlic powder, paprika, salt, and pepper.
Toss the potatoes until evenly coated with the seasoning mixture.
Place seasoned potatoes in a large baking dish or sheet pan.
Pat chicken thighs dry and place them on top of the potatoes.
Sprinkle grated Parmesan cheese evenly over the chicken and potatoes.
Bake for 35–40 minutes until chicken skin is crispy and potatoes are tender.
For extra crispiness broil for 2–3 minutes at the end of cooking.
Remove from oven and garnish with fresh parsley before serving.
