I would venture to say that, along with chicken parmigiana, chicken scarpariello is one of the most recognized chicken recipes in America. Chicken scarpariello is a composition of a few favorite ingredients: chicken, lots of garlic, and vinegar. In this recipe, I added some sausage, which is not unusual, especially if you have a big brood coming over. To multiply the recipe: Proceed in batches; then, once you have brought the whole thing to a boil, transfer to a roasting pan and finish cooking in a 450-degree oven, stirring the chicken periodically so all the pieces get crispy.
Season the chicken all over with the salt. Pour the olive oil into a large cast-iron skillet set over medium heat. Add ½ of the chicken and sausage (or use enough to fit in the skillet without crowding), and brown all over, about 5 minutes. Remove to a plate, and repeat with the second batch of chicken and sausage.
Return all of the chicken and sausage to the skillet. Add the garlic, and let everything brown and caramelize together for 3-4 minutes. Pour the vinegar into the skillet, bring to a boil, and cook until syrupy, about 2-3 minutes. Reduce heat to low, and sprinkle with the dried oregano. Cover the skillet, and cook until the chicken and sausage are glazed and the chicken is tender, about 20-25 minutes.
