I made this simple recipe because I had everything it called for laying around. These are standard pantry items for me. As I mentioned, it was simple and it turned out to be quite tasty.
- 1/4 cup whole-grain mustard
- 3 tablespoons extra-virgin olive oil
- Juice of 1 lemon
- 2 teaspoons mixed peppercorns, crushed
- 2 cloves garlic, grated
- Kosher salt
- 8 skin-on, bone-in chicken thighs (5 to 6 ounces each)
- 1 1/2 pounds fingerling potatoes, halved lengthwise
- 2 teaspoons chopped fresh rosemary
- 1 red or green bell pepper, cut into strips
Position racks in the upper and lower thirds of the oven; preheat to 450 degrees F. Whisk 1/2 cup water, the mustard, 1 tablespoon olive oil, the lemon juice, peppercorns, half of the garlic and 1/4 teaspoon salt in a bowl. Add the chicken and toss. Loosen the skins and rub some of the mustard mixture underneath. Transfer the chicken to a rimmed baking sheet, skin-side up. Roast on the upper rack until golden and crisp, 25 minutes.
Meanwhile, put the potatoes and 1/2 cup water in a microwave-safe bowl. Cover with plastic wrap; pierce a few times with a knife to vent. Microwave until just tender, 10 minutes. Drain and pat dry. Combine the remaining garlic, 2 tablespoons olive oil, the rosemary and 3/4 teaspoon salt in a bowl. Add the potatoes and bell pepper; toss. Transfer to a separate rimmed baking sheet. Roast on the lower rack until the vegetables are tender and golden, about 20 minutes.
Remove the chicken from the oven and let rest. Move the vegetables to the upper oven rack and continue roasting until browned, 5 more minutes. Serve with the chicken and any pan juices.
