Ingredients:
2 1/2 cups buttermilk
2 tablespoons extra-virgin olive oil
8 skin-on, chicken thighs
Kosher salt, to taste
Freshly ground pepper, to taste
3 heads garlic
4 to 6 sprigs fresh rosemary
8 slices sourdough bread, toasted
2 tablespoons white wine vinegar

Directions:
To marinate the chicken, add the buttermilk  to a large bowl, followed by the  chicken, Cover with plastic wrap and place in the refrigerator for 30 minutes. Allow the chicken to marinate  overnight for best results.

Heat the oven to 425 º F.

Heat the olive oil in a large cast iron skillet over medium-high heat. Season the chicken with salt and pepper and cook, skin-side down, until browned, about 5 minutes.

Separate the heads of garlic into cloves but do not peel. Flip the chicken; add the garlic and rosemary to the skillet and transfer to the oven. Roast until the chicken is cooked through but still moist, 15 to 20 more minutes.

Place the bread on a platter and top each slice with a chicken thigh. Add the vinegar to the skillet and scrape up any fond ( browned bits) with a wooden spoon. Add 3 tablespoons water and simmer until the sauce thickens slightly, about 2 minutes. Pour the sauce and garlic over the chicken and bread.

Cook’s Notes:
You can squeeze the garlic out of its skin and spread on the chicken or bread.
