This is a recipe that has gradually evolved over several years at our house. My family loves this meal---the chicken is roasted on a broiler pan while thinly sliced potatoes are layered on the drip pan underneath. As the chicken cooks, the flavors drip down onto the potatoes; they're so delicious! The sauce is creamy and tangy and is great on both the chicken and the potatoes. We usually eat this with sauteed green beans on the side.
