Why You’ll Love This Recipe
There’s a lot to appreciate about a recipe that relies on just three simple ingredients.
Bone-in, skin-on chicken thighs are especially good here because they stay moist and flavorful during baking. The skin becomes beautifully browned while the chicken releases flavorful juices into the dish.
The onions become soft and tender underneath the chicken, soaking up the dressing and savory juices as they cook. Their natural sweetness balances the tangy dressing and creates a delicious sauce.
Russian dressing does most of the seasoning work. Its combination of sweetness, acidity, and savory flavor transforms the chicken and onions into something much more flavorful than you might expect from such a short ingredient list.
And because everything cooks together in one baking dish, cleanup is simple too.
Ingredients You’ll Need
Bone-In, Skin-On Chicken Thighs
Chicken thighs are a great choice because they have enough natural fat to remain tender during oven baking. Keeping the skin on also adds richness and helps protect the meat as it cooks.
For the best browning, place the thighs skin-side up and leave a little space between each piece rather than crowding the pan.
Sweet Onion
Sweet onions add moisture and a gentle sweetness to the dish. As they bake beneath the chicken, they become soft and tender while absorbing the flavorful juices and dressing.
Yellow onions can be substituted, although sweet onions provide a milder flavor that works particularly well with the tangy sauce.
Russian Dressing
Russian dressing is the key ingredient that brings everything together. It provides sweetness, acidity, seasoning, and moisture in one convenient addition.
Different brands can vary in thickness, sweetness, and spice. A thicker dressing will create more of a glaze, while a thinner one will produce extra sauce in the bottom of the dish.
How to Make 3-Ingredient Chicken Charleston
- Prepare the oven. Preheat your oven to 350°F (175°C).
- Prepare the onion. Slice the sweet onion and spread the slices evenly across the bottom of a baking dish.
- Add the chicken. Arrange the chicken thighs over the onions with the skin facing upward.
- Add the dressing. Spoon or pour the Russian dressing over the chicken, allowing some of it to run down onto the onions.
- Bake. Place the uncovered dish in the preheated oven and bake until the chicken is thoroughly cooked and the skin is nicely browned.
- Check the temperature. Use an instant-read thermometer inserted into the thickest part of the thigh, avoiding the bone. The chicken should reach at least 165°F (74°C).
- Rest and serve. Let the chicken rest briefly before serving. Spoon some of the tender onions and pan sauce over each portion.
