Place the head of garlic with the thyme inside the cavity. Truss the chicken.
Heat butter and oil in a heavy pan on the top of your stove.
Roll the chicken in the pan to cover the whole chicken.
Rest the chicken on its side, and place in the middle of a
pre-heated 450F oven. Let roast for 15 minutes, then repeat on the other side
for another 15 minutes.
Now place the chicken on its back (breast up) roast for 40
minutes, but you need to baste every 5-10 minutes (the more the better).
