Ingredients
  

  • 2 cups cooked chicken, chopped (rotisserie works beautifully)
  • 4 cups s cooked pasta (penne, rigatoni, or cavatappi)
  • 3 tbsp s unsalted butter
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 2 tbsp all-purpose flour
  • 1 cup milk (whole milk preferred for richness)
  • ½ cup sour cream
  • cups shredded cheese (divided) – cheddar, Colby Jack, or a blend
  • ½ tsp red pepper flakes
  • Salt and black pepper, to taste

Optional Garnish:

  • Fresh parsley or chives for color
  • Crushed Ritz crackers or breadcrumbs for crunch

Instructions
 

  • Preheat the Oven
    Preheat to 350°F (175°C) and lightly grease a 9x13-inch baking dish.
  • Sauté the Aromatics
    In a large skillet, melt the butter over medium heat. Add diced onion and sauté until soft and fragrant — about 3 minutes. Stir in minced garlic and cook for 30 seconds more. The goal here is a mellow, golden base that anchors the flavor.
  • Make the Creamy Cheese Sauce
    Sprinkle the flour over the onion mixture and stir for about a minute to remove the raw taste.Gradually whisk in milk until smooth and slightly thickened.Reduce the heat, then stir in sour cream, 3 cups of cheese, red pepper flakes, salt, and pepper.Keep whisking until everything melts into a silky sauce that clings to your spoon.
  • Combine Chicken, Pasta, and Sauce
    In a large mixing bowl, combine cooked pasta, chopped chicken, and the cheese sauce. Toss gently until every piece is coated in that rich, creamy goodness.
  • Assemble and Bake
    Spread the mixture evenly into the prepared baking dish. Sprinkle the remaining ½ cup cheese on top — or more if you love that golden crust.Bake uncovered for 20–25 minutes, until bubbling and lightly browned on top.
  • Rest and Serve
    Let the casserole rest for about 5 minutes before serving. It’ll thicken slightly and cut more cleanly.
