- 2 (15-ounce) cans white beans, drained and rinsed
- 2 tablespoons capers with brine
- 8 teaspoons Dijon mustard
- 8 skin-on bone-in chicken thighs (about 2 pounds)
- 1 large lemon, thinly sliced, seeds removed
- 2 tablespoons olive oil
- 1 1/2 teaspoons kosher salt
- 1/2 teaspoon freshly ground black pepper
- 2 tablespoons coarsely chopped fresh parsley
- Position rack in upper third of oven and preheat to 425°F. Toss beans and capers in a 13×9″ baking dish and spread out evenly on bottom of pan. Spread 1 tsp. mustard on skin of each chicken thigh and nestle, skin side up, into beans and capers. Arrange lemon slices under and around chicken and add enough water (about 1/3 cup) to come up sides of chicken by 1/2″. Drizzle chicken with oil and season whole dish with salt and pepper.
- Roast chicken, stirring and shaking dish halfway through, until skin is browned and an instant-read thermometer inserted into thickest part of chicken registers 165°F, about 35 minutes. If chicken skin starts to burn, move pan to a lower rack to finish cooking.
- Transfer chicken, beans, lemon slices, and capers to a serving platter. Spoon some of the pan sauce around chicken and sprinkle with parsley.
