Preheat oven to 425°F and line a baking sheet with parchment paper.
Pound chicken using a rolling pin or meat mallet so they have even thickness.
Combine the paprika, oregano, garlic powder, onion powder, salt and pepper and olive oil in a large bowl. Place the chicken in the bowl and toss to combine so the chicken is evenly coated with the seasoning all around.
Bake chicken in preheated oven for 16-18 minutes, or until internal temperature is 165°F.
Broil on high heat until golden, about 2-3 minutes. Allow chicken to rest on baking sheet for 5 minutes before serving or cutting.
To serve, drizzle pan juices over the chicken and garnish with freshly chopped parsley.
