The secret to moist and flavorful roasted or baked chicken is to stuff the chicken cavity with a whole onion. I got this little trick from a friend who baked several wonderful chickens for Thanksgiving one year with a whole apple stuffed inside each one. For a while, I did the same until one day (when I had no apples on hand) I stuffed a chicken with an entire onion. The flavor was so great I’ve been baking chicken the same way ever since.
