Baked Chicken with White Beans and Tomatoes

Put oven rack in middle position and preheat oven to 350 °F. Cook bacon in a 10-inch heavy ovenproof skillet over moderate heat, stirring occasionally, until browned and crisp, about 8 minutes. Transfer bacon with a slotted spoon to paper towels to drain, reserving fat in skillet. While bacon is browning, pat chicken dry and season with 1/2 teaspoon salt and 1/4 teaspoon pepper. Brown chicken in fat in skillet over moderately high heat, turning over once, about 8 minutes total, then transfer chicken with tongs to paper towels to drain. Pour off all but 3 tablespoons fat from skillet and reduce heat to moderate. Cook onions in skillet with 1/4 teaspoon salt, stirring and scraping up any brown bits, until golden brown, about 10 minutes. Stir tomatoes and juice into onions and boil, uncovered, 3 minutes, to concentrate juices slightly. Stir in bacon and beans and bring to a simmer. Nestle chicken, skin side up, in beans and bake, uncovered, until chicken is cooked through, 20 to 25 minutes.
