The Ingredients

This recipe uses simple, affordable ingredients that come together beautifully.

6 bone-in, skin-on chicken thighs – Bone-in, skin-on thighs stay juicy and develop beautifully crispy skin. Don’t substitute boneless, skinless—you’ll lose flavor and moisture.
1 large sweet onion, sliced into rings – Vidalia, Walla Walla, or any sweet onion works beautifully. They caramelize as they bake.
1 cup Russian dressing – The secret weapon. Use your favorite brand, or make homemade. It’s tangy, sweet, creamy, and packed with flavor.

Step-by-Step Instructions

Step 1: Prepare the Oven and Baking Dish

Heat the oven to 350°F (175°C). Lightly coat a 9×13-inch baking dish, or a similar-sized casserole dish, with cooking spray or a small amount of oil.

Pro Tip: A glass or ceramic baking dish works best—it heats evenly and lets you see the beautiful golden pan sauce forming.

Step 2: Create the Onion Layer

Separate the sliced sweet onion into rings and spread them evenly across the bottom of the prepared dish. The onions will form a sweet, flavorful bed for the chicken and will soak up all the savory-sweet goodness from the dressing as it bakes.

Pro Tip: Don’t skip the onion layer. It’s the foundation of this dish and creates that incredible jammy texture.

Step 3: Arrange the Chicken

Place the chicken thighs over the onions in a single layer, keeping the skin facing upward so the tops can brown as they bake.

Pro Tip: Pat the chicken thighs dry with paper towels before placing them in the dish. Dry skin = crispy skin.

Step 4: Coat with the Dressing

Spoon the Russian dressing across the chicken thighs, distributing it evenly so every piece is well covered. Don’t be shy—you want a generous coating on each thigh.

Pro Tip: Use the back of a spoon to spread the dressing evenly. It will slide down the chicken and mix with the onions as it bakes.

Step 5: Bake to Golden Perfection

Transfer the dish to the preheated oven and bake uncovered for 45–50 minutes, or until the chicken is nicely browned and an instant-read thermometer inserted into the thickest part of a thigh registers at least 165°F (74°C) without touching the bone.

Pro Tip: For extra crispy skin, broil for 1-2 minutes at the end, watching closely to prevent burning.

Step 6: Rest and Serve

Remove the baking dish from the oven and allow the chicken to rest for about 5 minutes. This allows the juices to redistribute and the sauce to thicken slightly. Serve each thigh with the tender onions and spoon some of the flavorful pan sauce over the top.

Pro Tip: Serve over mashed potatoes, rice, or egg noodles to soak up every drop of that delicious pan sauce.

Pro Tips for the Best Chicken Charleston

Use bone-in, skin-on thighs. They stay juicy and develop crispy skin.

Don’t skip the onion layer. It’s the foundation of the dish.
Use a good Russian dressing. The quality of the dressing matters.
Bake uncovered. This allows the skin to brown and the sauce to thicken.
Check the temperature. Chicken should reach 165°F internally.
