What You Need
Butter or olive oil
1 or more boneless, skinless chicken breasts
Salt and pepper
Other spices or seasonings
Heat the oven to 400°F and prepare the pan: Heat the oven to 400°F with a rack in the middle position. Rub the pan and one side of the parchment paper with butter or olive oil; this prevents the chicken from sticking.
Prepare the chicken: Pat the chicken dry and rub with a little butter or olive oil, if desired. Sprinkle with salt, pepper, and any other favorite seasonings.
Transfer to the baking dish: Place the chicken breasts in the baking dish, spaced slightly apart. You can also tuck herbs or lemon wedges around the chicken for extra flavor.
Cover with the parchment: Lay the parchment, butter-side down, over the chicken. Tuck the edges into the pan and press the parchment down so that it’s snug around the chicken. The chicken breasts should be completely covered with the parchment.
Bake for 30 to 40 minutes: Transfer the chicken to the oven and bake for 30 to 40 minutes, until the chicken is completely opaque all the way through and registers 165°F on an instant-read thermometer.
Serve: Serve the chicken immediately, or let it cool and refrigerate for up to a week.
