Preheat your oven to 425°F (220°C).
Pat the chicken dry using paper towels.
In a large bowl, combine olive oil, smoked paprika, garlic powder, salt, black pepper, and rosemary.
Add the chicken thighs and drumsticks to the bowl, tossing them to coat thoroughly.
Place the chicken on a baking sheet lined with parchment paper.
Roast the chicken in the preheated oven for about 35-40 minutes.
Let the chicken rest for 5-10 minutes before serving.
