Ingredients:

  • 1.5 lbs (680g) boneless, skinless chicken breasts, about 4 breasts
  • 1 packet (1 oz or 28g) dry ranch dressing mix (e.g., Hidden Valley Ranch)
  • 1/2 cup (120ml) sour cream or Greek yogurt
  • 1/4 cup (60ml) milk or chicken broth
  • 1/4 cup (30g) grated Parmesan cheese
  • 1/4 cup (30g) shredded cheddar cheese (optional, for topping)
  • 1 tablespoon olive oil or melted butter (for greasing the baking dish)
  • Salt and freshly ground black pepper, to taste

Instructions:

  1. Preheat oven to 375°F (190°C). Grease a 9x13 inch baking dish with olive oil or melted butter.
  2. In a mixing bowl, whisk together the dry ranch dressing mix, sour cream (or Greek yogurt), and milk (or chicken broth) until smooth. Season with salt and pepper to taste.
  3. Place the chicken breasts in the prepared baking dish. Pour the ranch sauce evenly over the chicken, ensuring each breast is well coated.
  4. Sprinkle the grated Parmesan cheese evenly over the chicken. If desired, add shredded cheddar cheese as well.
  5. Bake in the preheated oven for 30-35 minutes, or until the chicken is cooked through and the internal temperature reaches 165°F (74°C). The sauce should be bubbly and the chicken should be slightly golden brown.
  6. Let the chicken rest for a few minutes before serving.
