Ingredients for 3-Ingredient Charleston Chicken
This recipe makes approximately four servings.
1. Chicken thighs
Use 2 pounds of boneless, skinless chicken thighs, or approximately 4–6 pieces depending on their size.
Chicken thighs are a great choice because they have a rich flavor and tend to remain moist during baking. They also work well with sweet-and-savory sauces.
Bone-in thighs can be used, but they may need more cooking time. Always check the thickest part of the chicken with a food thermometer rather than relying only on the estimated cooking time.
2. Onions
Use 2 medium yellow onions, sliced into rings or thick half-moons.
Yellow onions are ideal because they become soft and sweet as they cook. Their flavor blends naturally with the sauce and chicken juices.
Slice the onions evenly so they soften at a similar rate. Thicker slices will retain more texture, while thinner slices will become softer and more integrated into the sauce.
3. Honey-mustard barbecue sauce
Use approximately 1 cup of prepared honey-mustard barbecue sauce.
Choosing a ready-made sauce keeps the recipe simple because it combines several flavors in one ingredient. Depending on the brand, it may provide sweetness from honey, tanginess from mustard, and a smoky or savory note from barbecue seasoning.
Check the label before using it, especially if you need to avoid specific allergens or ingredients. Different sauces vary in sweetness, thickness, salt content, and acidity.
Important: This is a three-main-ingredient version. If you add oil, salt, pepper, garlic, or herbs, those are additional ingredients, so keep them optional if you want to maintain the three-ingredient claim.
Kitchen Equipment
You will need:
- A medium or large oven-safe baking dish
- A cutting board
- A sharp knife
- Measuring cup
- Tongs or a serving spoon
- A food thermometer
Choose a baking dish that allows the chicken to sit in a reasonably even layer. If the pieces are crowded too tightly, they may release moisture and steam instead of browning.
How to Make 3-Ingredient Charleston Chicken
Step 1: Preheat the oven
Preheat your oven to 400°F (200°C).
Choose a baking dish large enough to hold the chicken and onions without packing them too tightly. If your dish is not nonstick, you can use a small amount of oil to prevent sticking, but remember that oil would count as an additional ingredient.
Step 2: Prepare the onions
Peel the onions and cut them into rings or thick slices.
Spread most of the onions across the bottom of the baking dish. This creates a flavorful bed for the chicken and helps keep the onions in contact with the cooking juices.
Reserve a few onion slices to arrange around or over the chicken if you want the finished dish to resemble the supplied photograph.
Step 3: Arrange the chicken
Pat the chicken thighs dry with paper towels if they are very wet. Place them over the onions in a single layer.
Try to leave a little space between the pieces so the heat can circulate. If you are using large bone-in thighs, arrange them with the thicker portions facing outward where possible.
Wash your hands and clean any utensils or surfaces that have touched raw chicken. Keep raw chicken separate from ready-to-eat foods.
