Instructions

    Cup of Yum
  1. Preheat the oven to 350°F (180°C) and adjust the oven rack to the middle position. Generously butter a 9-by-13-inch baking dish or shallow 3-quart casserole dish.
  2. Pat the chicken dry with paper towels. Either chop the chicken breasts into 1-inch chunks or place each chicken breast on a work surface and, using a sharp knife held parallel with the surface, cut the breast in half horizontally to create 8 chicken pieces. In a small bowl, mix together the thyme, sage, 1 teaspoon salt, and pepper. Set aside 1 teaspoon herb mixture. Season the chicken on all sides with the remaining herb mixture.
  3. Peel the sweet potatoes and cut into 1/4-inch-thick rounds. Stack several rounds on top of each other and cut into 1/4-inch-wide strips. Peel the onion, halve through the root end, and slice into 1/4-inch-wide strips.
  4. In a large skillet over medium heat, warm 3 tablespoons oil until hot. Add the chicken and sauté until lightly browned but not cooked through, 2 to 3 minutes per side. Remove the chicken to the prepared baking dish. Add the chicken broth and wine to the skillet and whisk to scrape up any browned bits on the bottom. Cook, stirring until the liquid has reduced to 1/4 cup, 3 to 4 minutes. Pour over the chicken breasts.
  5. In the same skillet set over medium heat, fry the bacon until crisp, 5 to 10 minutes. Drain on paper towels and, when cool, chop coarsely. Pour off all but 1 tablespoon drippings and reserve for another use. To the drippings in the skillet add the remaining 2 tablespoons olive oil. Place the skillet over medium heat, and when hot, add the sweet potatoes and onion and sauté, stirring, until softened, 7 to 8 minutes. Season the vegetables with salt and spoon them over the chicken. Sprinkle with the bacon.
  6. In a medium saucepan over medium heat, melt the butter. Add the flour and cook, stirring constantly, for 1 1/2 to 2 minutes.
  7. Gradually whisk in the milk and the reserved 1 teaspoon of seasoning. Bring the mixture to a gentle boil, whisking constantly, and cook until it thickens enough to coat the back of a spoon, about 3 minutes from the time the sauce begins to boil. The sauce will be quite thick. Taste the sauce and season with salt if needed. Dab the sauce over the ingredients in the casserole and sprinkle with the Gruyère. Cover the casserole loosely with a sheet of foil.
  8. Bake the casserole until the chicken is cooked through and tender, 20 to 30 minutes. Remove from the oven and let cool for 5 minutes before bringing it to the table. If desired, garnish the center of the dish with some sage and thyme sprigs before serving.
