Well, If you’re starting with a whole chicken, you need to remove the (kinda sounds gross) organs from the cavity.
I always wear latex gloves for this part. Once that is done, rinse the whole chicken under cool water and put it, breast side up, into your favorite baking pan.
(I put my seasonings in a separate small bowl first before beginning.)
With the gloves still on, I season mine liberally with my favorite seasoning (Lawry’s, garlic and Herbs D’Provence) both on the top of the skin, and underneath the skin on the breast.
Bake at 350 for 1 hr and 15 minutes or until the juices are clear. Let cool for about 15 minutes before serving.
