Directions

1. Heat the oven to 400°F. In a large skillet over high heat, heat the oil until it shimmers. Add the shallots and immediately reduce the heat to medium. Add a pinch of salt, and sauté until the shallots are soft and translucent, about 5 minutes.
2. Meanwhile, place the chicken in a large bowl. Pat dry. Season all over with salt and pepper. (Note: If you’ve salted ahead (see notes above), do not add more salt; just add pepper to taste.)
3. Add the tomatoes to the pan and cook for 1 minute. Add the mustard and cook for 30 seconds, stirring to incorporate it. Add the sherry, sherry vinegar, and water and bring to a simmer. Transfer the chicken pieces to the pan skin side up. Transfer pan to the oven and roast for 40 to 50 minutes or until the skin is evenly golden brown.
4. Remove pan from the oven, and transfer chicken to a plate to rest. Pour juices from the pan into a large bowl or large liquid measure. Let liquids sit for a minute or two until the fat rises to the surface. Use a spoon or ladle to remove fat. Taste juices. Adjust with salt or pepper. Return juices and chicken to the pan. Bring to a gentle simmer. Serve chicken with plenty of juices pooling all around—I like using shallow bowls for this one. Serve with crusty bread, if you wish.
