Bake in the upper part of the oven for 60 minutes, until the tops are nicely browned and the internal temperature has reached 165F.Tip:
everyone's oven bakes differently, as they say, so you may want to check the internal temperature and adjust baking time to your liking the first time you make it. At 375F and 60 minutes my chicken breasts come out at slightly higher than 165F internal but that's never an issue as they taste surprisingly tender and juicy. I sometimes let my chicken breasts bake for 75 minutes at this temperature to get better browned tops, and they still came out very tender and juicy. I do recommend 75 minutes of baking time if you use cold broth.
That's the beauty of this recipe: I never check internal temperature as I know that my chicken breasts won't be under-cooked, yet they will be delicious and succulent.
