In a large skillet, heat olive oil over medium-high heat. Season the chicken breasts with salt, pepper, garlic powder, and onion powder.
Sear the chicken breasts in the skillet for about 4-5 minutes on each side until golden brown (they do not need to be fully cooked through). Remove from the skillet and set aside.
In a medium bowl, mix together the ranch dressing, cream cheese, and chicken broth until smooth and well combined.
In an oven-safe baking dish, place the seared chicken breasts in a single layer. Pour the ranch mixture over the chicken, ensuring they are well coated.
Sprinkle the shredded cheddar cheese on top of the ranch mixture.
Cover the baking dish with aluminum foil and bake in the preheated oven for 25-30 minutes, until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).
Remove the foil and bake for an additional 5-10 minutes to allow the cheese to bubble and turn slightly golden.
Once baked, remove from the oven and garnish with fresh chives before serving.
Notes
Pair with steamed broccoli or a mixed green salad for a complete meal, and serve with crusty bread to soak up the creamy sauce.
