Preheat oven to 400ºF. Wash and pat dry your chicken. Coat in salt, pepper and herbes de Provence and then dredge in flour.
In a roasting pan, add olive oil and spread around. Neatly position your chicken a few inches apart in the pan. Peel and quarter your shallots and cut your lemon into pieces. Peel garlic but leave in full clove form. Arrange lemon, shallots, olives, tomatoes, garlic and fresh herbs around your chicken.
Season again with salt/pepper/ dried herbs and pour Vermouth overtop the whole dish. Roast for about 10 min. Check and make sure your chicken is moist, and add a squeeze of lemon if it’s feeling dried out. Cook for another 12-15 min or until the internal temperature of the chicken is 165ºF.
Remove, and enjoy with a few more squeezes of lemon!
