Step 1
Start by heating your oven to 400°F (200°C). In a small bowl, mix together the garlic powder, paprika, mustard, parsley, salt, and pepper. Rub each chicken breast all over with olive oil, then sprinkle the spice mix evenly on every side. Arrange the chicken on a baking sheet and place a tablespoon of butter on top of each piece. Cover each breast with a piece of parchment paper, folding the edges underneath to create a little sealed pouch. Pop the chicken in the oven and bake for about 35 minutes, or until it’s cooked through and no longer pink inside. To be sure, check that the internal temperature reaches 165°F (74°C) with a meat thermometer. Once done, let the chicken rest for 5 minutes before serving to keep it juicy.
