This oven baked 3-ingredient Chicken Charleston is the kind of simple, dependable dinner that earns a permanent spot in the family recipe box. It comes together with just a few pantry staples, but the oven does the heavy lifting, turning chicken and onions into a glossy, savory-sweet dish that feels a little nostalgic in the best way. Recipes like this became popular in the 1970s for a reason: they were practical, affordable, and easy enough for busy home cooks to make again and again.
Serve Chicken Charleston with fluffy white rice, buttered egg noodles, or mashed potatoes to catch every bit of the sauce. A simple green bean side, steamed broccoli, or a crisp salad balances the richness nicely, and warm rolls are always welcome if you want a full comfort-food meal.
Oven Baked 3-Ingredient Chicken Charleston
Servings: 4 to 6
Ingredients
6 bone-in, skin-on chicken thighs
Directions
1. Preheat the oven to 350°F and lightly grease an oval baking dish or 9x13-inch casserole dish.
2. Arrange the sliced onion rings across the bottom of the dish, then place the chicken thighs on top in a single layer.
3. Spoon the Russian dressing evenly over the chicken, making sure each piece is well coated.
4. Cover the dish tightly with foil and bake for 45 minutes.
5. Remove the foil, spoon some of the pan sauce over the chicken, and continue baking for 25 to 35 minutes more, until the chicken is cooked through and the onions are soft and caramelized.
6. Let the dish rest for 5 minutes before serving, then spoon the onions and sauce over each piece of chicken.
Variations & Tips
Use chicken breasts: If you prefer white meat, boneless or bone-in chicken breasts can work here too. Just keep an eye on doneness since breasts may cook a little differently and can dry out sooner than thighs.
Add a pantry boost: A light sprinkle of black pepper, garlic powder, or paprika is an easy way to add a little more depth while still keeping the recipe very simple.
Make it weeknight-friendly: Slice the onion and assemble the dish earlier in the day, then keep it covered in the refrigerator until you’re ready to bake. That kind of prep always helps on busy evenings.
Thin the sauce if needed: If your dressing is very thick, stir in a tablespoon or two of water before spooning it over the chicken so it spreads more evenly and creates more pan sauce.
Serve from the baking dish: This recipe has a cozy, old-fashioned feel, so bringing the whole stoneware dish to the table works perfectly. It also keeps the onions and sauce together, which is honestly the best part.
