that's what the tent does - I do it Italian style, eight heads of garlic in a Le Creuset pot, maybe 4 with 4 shallots, dobs of rosemary in the base and on the chicken, the chicken seasoned with lemon pepper, lemon and salt.
Cook for 1,5 hours @200F 180 fan and a medium-sized bird...half way through the roast add 1/4 bottle of white wine....
Let the chicken rest and reduce the sauce, add whatever be it creme fraiche and other herbs or a touch of balsamic and maple syrup..... ...one meal is the result.
The cold chicken remains are delish in having been half-poached and really good for adding to salads or risotto.
