For a healthier version, use skinless boneless chicken thighs, or breast. Feel free to marinate overnight in a zip lock bag. Cooking time will shorten significantly, so you may have to remove chicken and let potatoes continue cooking to get them crispy.
For WHOLE CHICKENS! The baking time for the chicken will vary depending on the size (weight) of the chicken. This one in the photos was a small 3.5 pound chicken. Larger 5-6 lb chickens will take longer in the oven ( 70-90 minutes). So plan accordingly.
***Use a large rimmed metal sheet pan, rather than a glass baking dish so air can circulate and potatoes can get crispy! (This enamel baking dish in the photos is much larger than it looks! )
