Preheat the oven to 400 degrees and grease a baking dish with a little olive oil or spray. Tip: use the smallest oven-safe dish you can fit the breasts tightly to help them retain their juices.
Pat dry the chicken breasts with a couple of paper towels. Season them generously with salt and pepper on both sides.
Place the seasoned chicken breasts in the prepared dish and drizzle the olive oil over the tops of the breasts. Pour the chicken broth or water into the bottom of the baking dish.
Bake:
Bake the chicken breasts in the preheated oven for about 25 minutes until the internal temperature of the chicken has reached 165F. After 20 minutes, I recommend opening the oven and basting the chicken breasts with the juices in the dish a couple of times to ensure they stay juicy.
Remove them from the oven and let them rest for 5 minutes.
Serve:
If you have a lemon, slice it in half and squeeze it over the top of the breasts right before serving.
