Instructions
 

Preparation

  • Preheat oven to 375°F (190°C). Grease a 9x13 or similar baking dish.
  • Bring a large pot of salted water to a boil. Cook 8 oz penne or rotini until al dente, reserving about 1/2 to 1 cup of pasta cooking water.
  • Drain the pasta and set aside.

Making the Sauce

  • While pasta cooks, melt 2 tbsp butter in a skillet over medium heat. Add 4 cloves minced garlic and sauté until fragrant but not browned.
  • Reduce heat slightly and pour in 1 cup heavy cream slowly, stirring to combine. Warm the cream for 1–2 minutes.
  • Stir in 1 cup freshly grated Parmesan until it melts and the sauce becomes smooth. Adjust the consistency with reserved pasta water as needed.
  • Season the sauce with salt and pepper to taste.

Combining and Baking

  • Add the cooked chicken and drained pasta to the sauce. Toss gently to coat.
  • Transfer the mixture to the prepared baking dish and sprinkle extra Parmesan on top.
  • Bake for 25–30 minutes until bubbly and golden. Broil for an additional 1-2 minutes if desired.
  • Let rest for 5 minutes before serving.

Notes

Serve with a green salad dressed with lemon vinaigrette to balance the richness. For a crunchier topping, mix breadcrumbs with olive oil before baking. Store leftovers in an airtight container for up to 3-4 days.
