Ingredients
  

  • 12 ounces short pasta (penne, rotini, or shells)
  • 3 cups cooked chicken, shredded or cubed (rotisserie works great)
  • 8 slices bacon, cooked and crumbled (reserve 1 tablespoon bacon fat if possible)
  • 1 tablespoon olive oil (plus reserved bacon fat if using)
  • 1 small yellow onion, finely diced
  • 3 cloves garlic, minced
  • 1 cup ranch dressing (thick, good-quality)
  • 1/2 cup sour cream or plain Greek yogurt
  • 1/2 cup chicken broth or milk (for a looser, creamier sauce)
  • 2 cups shredded cheddar cheese, divided
  • 1 cup shredded mozzarella or Monterey Jack, divided
  • 1/2 teaspoon smoked paprika (optional, for a subtle smoky note)
  • 1/2 teaspoon black pepper
  • 1/4–1/2 teaspoon kosher salt, to taste
  • 1/4 cup chopped fresh parsley or chives (plus more for garnish)
  • Optional add-ins: 1–2 cups steamed broccoli florets, peas, or sautéed mushrooms

Method
 

  1. Preheat and prep: Heat the oven to 375°F (190°C). Grease a 9x13-inch baking dish.
  2. Cook the pasta: Boil in well-salted water until just al dente. Drain and set aside. Don’t overcook—pasta will continue to soften in the oven.
  3. Crisp the bacon: Cook bacon in a skillet over medium heat until crisp. Transfer to a paper towel–lined plate. Crumble when cool. Reserve about 1 tablespoon of the bacon fat if you can.
  4. Sauté aromatics: In the same skillet, add olive oil and reserved bacon fat. Sauté onion for 3–4 minutes until translucent. Add garlic and cook 30 seconds until fragrant.
  5. Make the sauce base: Reduce heat to low. Stir in ranch dressing, sour cream (or yogurt), and chicken broth (or milk). Mix until smooth and warm. Add smoked paprika, black pepper, and a pinch of salt. Taste and adjust seasoning.
  6. Add cheeses: Stir in 1 cup cheddar and 1/2 cup mozzarella until just melted and creamy.
  7. Combine: In a large bowl, mix cooked pasta, chicken, half the crumbled bacon, sautéed onion/garlic, and chopped herbs. If using veggies, fold them in now. Pour the sauce over everything and toss to coat evenly.
  8. Assemble: Transfer mixture to the baking dish. Top with remaining cheddar and mozzarella. Sprinkle the rest of the bacon over the top.
  9. Bake: Bake 18–22 minutes, until the cheese is melted and bubbling at the edges. For a golden top, broil for 1–2 minutes, watching closely.
  10. Finish and serve: Let it rest 5–10 minutes. Garnish with extra parsley or chives. Serve warm.
