This 3-Ingredient Chicken Charleston is a wonderfully simple main course that combines tender bone-in chicken thighs, sweet onions, and flavorful Russian dressing. With only three ingredients, it is an easy recipe to prepare when you want a hearty homemade meal without a long ingredient list.

The sliced sweet onions cook underneath the chicken, becoming soft and flavorful as they absorb the juices from the chicken and the tangy dressing. The Russian dressing coats the chicken as it bakes, creating a rich, savory-sweet sauce that helps keep the chicken moist and flavorful.

This recipe is especially convenient because most of the cooking happens in a single baking dish. After the covered baking time, the chicken is uncovered and baked again until the skin becomes beautifully browned and the meat reaches a safe temperature. Serve the chicken hot with plenty of the tender onions and flavorful pan sauce for a comforting, satisfying meal.

Ingredients:

6 bone-in, skin-on chicken thighs
1 large sweet onion, cut into rings
1 cup bottled Russian dressing

Equipment:

9 × 13-inch baking dish
Aluminum foil

Instructions:

Preheat your oven to 350°F. Lightly grease the bottom of a 9 × 13-inch baking dish.
Arrange the sliced sweet onions in a single layer across the bottom of the prepared baking dish.
Place the chicken thighs skin-side up over the layer of onions.
Evenly pour the bottled Russian dressing over the chicken thighs, using a spoon to make sure each piece is well coated with the sauce.
Cover the baking dish tightly with aluminum foil and bake in the preheated oven for approximately 45 minutes.
Carefully remove the foil. Spoon some of the sauce from the bottom of the dish over the chicken thighs.
Return the uncovered dish to the oven and bake for an additional 25–35 minutes, or until the chicken is fully cooked and reaches an internal temperature of at least 165°F.
