Make the chicken
- Preheat the oven to 425°F (220°C).
- Scatter the chopped vegetables and onions in a roasting pan and drizzle with the oil. Add the lemon zest, thyme, salt, and pepper to the vegetables and, using your hands, mix until all the vegetables are coated and then spread into a single layer.
- Using paper towels, pat the chicken completely dry, inside and out.
- Cut both lemons in quarters and tuck them in the cavity of the bird with the smashed garlic and a few sprigs of fresh thyme. If all the lemon quarters don’t fit, you can pop them in the pan with the vegetables—just don’t forget to take them out when you serve the chicken.
- Rub the bird with 1 TSP of olive oil and season with salt, pepper and Herbs de Provence
- Place the bird directly on the vegetables in the roasting pan and place in the oven on the bottom rack for 20 minutes, until the skin starts to brown nicely.
Make the basting mixture
- In a small saucepan, melt the Ghee. Add the smashed garlic and place over very low heat. You will use this to baste the chicken while it’s roasting.
- Turn down the oven to 400˚F (200˚C) and roast the chicken for 60 to 70 minutes more, or until a meat thermometer inserted into the high part of the thigh registers 165˚F (74˚C). Normally you can count on about 20 minutes’ cook time per pound (454 g) of chicken but to be absolutely sure, a meat thermometer is the way to go
- While the bird is cooking, baste it every 20 minutes or so with the melted ghee and smashed garlic. This will season the bird even more.
- Once the chicken is cooked, remove it from the oven (leave the vegetables in the roasting pan), place it on a cutting board (preferably one that has a drain ridge to catch any juices), cover it loosely with aluminum foil and allow it to rest for about 10 minutes before you carve it.
- Give the vegetables a good stir and place the roasting pan back in the oven until you are ready to serve the meal. If the vegetables are not crisp enough, you can set the broiler to high (around 400˚F/200˚C, if your broiler has a temperature display) and broil them for about 5 minutes, but do keep an eye on them as they might burn.
