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.
2 tablespoons finely grated orange zest (from about 2 oranges)
1 cup freshly squeezed orange juice (from about 6 oranges)
1/4 cup finely chopped yellow onion or shallot
2 tablespoonsDijon mustard
2 tablespoons whole-grain mustard
2 tablespoons unsalted butter (1/4 stick), cut into 4 pieces and at room temperature
Heat the oven to 400°F and arrange a rack in the middle.
Season the chicken with 2 teaspoons of the salt and all of the pepper; set aside.
Place 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.
Remove the pan from the heat and whisk in the Dijon and whole-grain mustards.
Add the reserved chicken, spoon some of the sauce over each breast, and bake until the chicken is just cooked through, about 30 minutes.
Remove 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.
