Heat a skillet with 3 tablespoons of oil. Add the chicken, sear for 2 minutes on each side or until browned. Remove from the skillet and set aside.
Preheat the oven to 400ºF. Line a baking sheet pan with parchment paper.

Place the potatoes on one side of the prepared pan, and the chicken on the other side of the pan. Drizzle with the rest of the oil, cover with foil.
Place the chicken and potatoes in the oven for 4-5 minutes. Remove the foil, bake until the potatoes are tender and the chicken is cooked all the way through. Garnish with chopped parsley
