Ingredients Method Notes

Ingredients
  

  • 3 cups cooked chicken breast, shredded or cubed
  • 8 slices bacon, cooked and crumbled
  • 1 packet (1 oz) dry ranch seasoning mix
  • 1 can (10.5 oz) cream of chicken soup
  • 1 cup sour cream
  • 1½ cups shredded cheddar cheese, divided
  • 1 cup shredded mozzarella cheese
  • 3 cups cooked pasta (rotini or penne)
  • ½ cup milk
  • to taste salt and black pepper
  • fresh chives or parsley for garnish (optional)

Method
 

Preheat and Prep Your Pan
  1. Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with cooking spray or a thin layer of butter.
Cook the Bacon
  1. In a skillet over medium heat, cook your bacon until it's deeply golden and crisp. Transfer to a paper towel-lined plate and let it cool before crumbling.
Make the Creamy Ranch Sauce
  1. In a large mixing bowl, combine the cream of chicken soup, sour cream, milk, and dry ranch seasoning. Stir until smooth and well blended. Season lightly with salt and pepper.
Bring It All Together
  1. Add the cooked pasta, shredded chicken, half the crumbled bacon, and 1 cup of the cheddar cheese into the bowl with your ranch sauce. Fold everything together gently until every piece of pasta and chicken is coated in the creamy mixture.
Assemble and Top
  1. Spread the mixture evenly into your prepared baking dish. Sprinkle the mozzarella and remaining cheddar cheese over the top in an even layer, then scatter the rest of the crumbled bacon over everything.
Bake Until Golden and Bubbling
  1. Place the dish in the preheated oven and bake uncovered for 30–35 minutes, until the cheese on top is golden and bubbly around the edges and the casserole is steaming and set in the center.
  2. Let it rest for 5 minutes before serving. Garnish with fresh chives or parsley if desired.

Notes

Meal-Prep Tip: Assemble the entire casserole the night before, cover tightly, and refrigerate. Bake the next evening, adding 5–10 extra minutes to the bake time. Store leftovers in an airtight container in the refrigerator for up to 4 days, or freeze for up to 2 months. Reheat refrigerated portions in the oven at 350°F for 15–20 minutes, or microwave individual servings. Add a splash of milk before reheating to keep the sauce creamy. Bake uncovered for a golden, slightly crisp cheese topping. Always use fully cooked pasta and fully cooked chicken before assembling. Let the casserole rest for 5 minutes before serving.
