6. Season generously with salt and pepper. Cover loosely with foil. Keep warm and let rest in oven with door open and platter tilted with chicken's head end down.
7. Meanwhile, prepare the sauce: Remove onions to a platter. Put the pan over moderate heat, scraping up any bits that cling to the bottom. Cook, scraping and stirring until the liquid is almost caramelized, 2 to 3 minutes. Do not let it burn. Spoon off and discard any excess fat. Add several tablespoons cold water to deglaze pan as needed. (Hot water will cloud the sauce.) Bring to a boil. Reduce heat to low and simmer until thickened, about 5 minutes.
8. While sauce is cooking, remove the lemons, giblets and thyme from the chicken cavity. Carve the chicken into serving pieces and transfer to a warmed platter. Chop the giblets and add to the platter. Squeeze the lemons over the chicken. Place two onion halves on each plate with chicken.
9. Strain the sauce through a fine-mesh sieve and pour into a sauce boat. Serve at once with chicken.
