This dish is a snap to make and a great way to use up extra oranges. Tons of fresh orange zest and juice is simmered with onion and honey, then Dijon and whole-grain mustards are added to make the base of a flavorful sauce for the chicken to bake in; to finish the sauce, just whisk in a little butter. Serve it all with a lentil salad for a healthy dinner.
- 1Heat the oven to 400°F and arrange a rack in the middle.
- 2Season the chicken with 2 teaspoons of the salt and all of the pepper; set aside.
- 3Place the orange zest, juice, onion or shallot, honey, and remaining teaspoon of salt in a large oven-safe frying pan, whisk to combine, and bring to a boil over medium-high heat. Reduce the heat to medium and simmer until reduced by almost half, about 3 minutes.
- 4Remove the pan from the heat and whisk in the Dijon and whole-grain mustards.
- 5Add the reserved chicken, spoon some of the sauce over each breast, and bake until the chicken is just cooked through, about 30 minutes.
- 6Remove the chicken to a serving platter and tent with foil. Whisk the butter into the sauce 1 piece at a time, letting each piece melt before adding the next. Spoon the sauce over the chicken and serve.
