Preheat oven to 425°F.
Remove any insides from cavity of chicken. Pat-dry entire chicken inside and out! Get under those wings and legs!
Unstick the skin from the meat with your fingers on the top and bottom of bird, so you can season between them!
Whisk together butter, oil, rosemary, and thyme. No salt & no pepper yet!
Lather the butter mixture all over chicken. First, between the skin and meat; then, all over the outside.
Season the outside, AND INSIDE THE CAVITY, of the chicken generously and evenly with salt and pepper. Stuff the hole with NANA'S FAMOUS STUFFING. Tie chicken legs together with cooking twine.
Place in roasting pan, cover tightly with tinfoil, and set in middle of oven. Bake for an hour.
Uncover chicken, baste, and put it back in the oven for half an hour or until an internal temp of 165°F is reached/juices run clear when cut. If bird starts to brown too much before it's done, just cover again with foil.
Remove chicken from oven and allow to rest, tented in foil. Let sit 10-15 minutes before carving!
