This recipe features buttermilk-marinated chicken thighs roasted in a cast-iron skillet with Yukon Gold potatoes. The chicken is initially roasted to develop flavor, then removed while the potatoes finish cooking at a higher temperature for crispness. The dish is completed by returning the chicken to the pan with fresh herbs before serving.
The buttermilk marinade is key to tender and moist chicken; ensure it's marinated for at least 4 hours. Starting the chicken skin-side up in a cool, oiled skillet helps achieve a crisp skin. Cooking the potatoes separately at a higher temperature after the initial roast ensures they crisp up nicely in the rendered chicken fat without overcooking the chicken thighs. Always use an instant-read thermometer for accurate chicken doneness (target 165F in thickest part, recipe suggests 155F then resting). Resting the chicken after roasting before adding back to the hot potatoes is crucial for juicy meat.
