Pan Roasted Chicken with Green Olives and Garlic

Ingredients:

3 tablespoons extra-virgin olive oil
4 ounces thinly sliced pancetta, cut into 1/2-inch-wide strips
One  package Chicken thighs with bone and skin

One package Chicken drumsticks with bone and skinKosher salt
Pepper
12 unpeeled garlic cloves, crushed
6 thyme sprigs, plus chopped thyme for garnish
1 cup dry white wine
1/2 cup (3 ounces) pitted green olives ( I use cocktail olives; rinse olives with water to remove salt)
6 tablespoons unsalted butter
Baby arugula  for serving

Directions:

Preheat the oven to 450°. In a large enameled cast-iron casserole, heat 1 tablespoon of the olive oil. Add the pancetta and cook over moderate heat, stirring occasionally, until golden, about 5 minutes. Using a slotted spoon, transfer the pancetta to a paper towel–lined plate.
Rub the chicken with the remaining 2 tablespoons of olive oil and season with salt and pepper. Add half of the chicken to the casserole, skin side down, along with half each of the garlic, thyme sprigs and rosemary. Cook over moderately high heat, turning, until golden brown all over, about 
5 minutes. Transfer the chicken to a large plate. Repeat with the remaining chicken, garlic, thyme and rosemary. Return all of the chicken and aromatics to the casserole.
Roast the chicken until the breasts are just cooked through, about 15 minutes. Transfer the breasts to a platter. Roast the chicken legs for 10 minutes longer, until cooked through. Add the chicken legs and garlic to the platter; discard the herb sprigs and garlic skins.
Pour off all of the fat from the casserole. Add the white wine, olives and pancetta and cook over moderately high heat, scraping up the browned bits on the bottom, until the wine is reduced by half, 2 to 3 minutes. Whisk in the butter and season with salt and pepper. Spoon the sauce over the chicken and top with arugula, chopped thyme.
