Ingredients You’ll Need
For the Chicken
6 bone-in, skin-on chicken thighs
1 large sweet onion, sliced into rings
1 cup Russian dressing
That’s it!
Tools You’ll Need
You only need a few basic kitchen tools:
9×13-inch baking dish or similar-sized casserole dish
Cutting board
Knife
Spoon
Cooking spray or a small amount of oil
Instant-read thermometer
The thermometer is particularly useful for confirming that the chicken has reached a safe internal temperature.
Ingredient Notes and Possible Substitutions
This recipe is specifically built around three ingredients, so the simplest approach is to use them as listed.
Chicken Thighs
The recipe calls for bone-in, skin-on chicken thighs. Keeping the skin facing upward during baking helps the tops brown.
Sweet Onion
A large sweet onion is sliced into rings and spread across the bottom of the baking dish.
Russian Dressing
The Russian dressing is spooned over the chicken before baking, giving the dish its distinctive flavor and contributing to the pan sauce.
If you change the ingredients, the cooking time and final result may also change, so the recipe's instructions are written specifically for the listed ingredients.
How to Make 3-Ingredient Chicken Charleston
Step 1: Prepare the Oven and Baking Dish
Preheat your 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.
Step 2: Create the Onion Layer
Separate the sliced sweet onion into rings.
Spread the onion rings evenly across the bottom of the prepared baking dish.
Step 3: Arrange the Chicken
Place the 6 chicken thighs over the onions in a single layer.
Make sure the skin is facing upward. This allows the tops of the thighs to brown as they bake.
Step 4: Add the Russian Dressing
Spoon the 1 cup of Russian dressing across the chicken thighs.
Distribute it evenly so that every piece is well covered.
Step 5: Bake
Transfer the uncovered baking dish to the preheated oven.
Bake 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.
The thermometer check is the important part here. Chicken should reach the specified internal temperature before serving.
Step 6: Rest and Serve
Remove the baking dish from the oven and let the chicken rest for about 5 minutes.
Then serve each chicken thigh with the tender onions.
Don’t forget the flavorful juices in the bottom of the dish! Spoon some of the pan sauce over the chicken before serving.
What to Serve With Chicken Charleston
Because this chicken already comes with tender onions and a flavorful pan sauce, it can be paired with simple side dishes.
Consider serving it alongside your favorite vegetable, potato dish, rice, or another simple side that can complement the pan sauce.
The source recipe does not specify particular side dishes, so these are general serving ideas rather than part of the original recipe.
Tips for Making the Best Chicken Charleston
Keep the Chicken Skin-Side Up
Arrange the thighs with the skin facing upward. This helps the tops brown as they bake.
Cover the Chicken Evenly
When spooning the Russian dressing over the chicken, try to distribute it evenly so every thigh is well coated.
Don’t Skip the Thermometer
Chicken can vary in size, so baking time alone isn't the best way to determine whether it is done.
Use an instant-read thermometer in the thickest part of a thigh, making sure it does not touch the bone. The recipe specifies a minimum internal temperature of 165°F (74°C).
Let It Rest
Give the chicken about 5 minutes to rest after removing it from the oven.
This also gives you a moment to gather the onions and spoon some of that flavorful pan sauce over each serving.
