Ingredients

Pasta and Vegetables

  • 1 pound rigatoni pasta or other ridged short pasta like penne
  • 1 1/2 cups fresh broccoli florets

Protein

  • 1 rotisserie chicken shredded (about 3 cups) Use leftover roasted chicken if needed.

Sauce and Cheeses

  • 2 cups creamy Alfredo sauce store-bought or homemade
  • 1 cup freshly shredded mozzarella cheese For best melt, use freshly shredded.
  • 1/2 cup grated Parmesan cheese

Seasonings

  • 1 tablespoon garlic powder
  • Salt and freshly ground black pepper to taste

Instructions

Preparation

  • Bring a large pot of salted water to a boil. Add the rigatoni and cook according to package directions until al dente. In the last 3 minutes of cooking, add the broccoli florets.
  • Drain pasta and broccoli, reserving about 1 cup of the pasta water. Set aside.
  • Preheat the oven to 375°F (190°C).
  • In a large bowl, combine the drained pasta, broccoli, shredded rotisserie chicken, and Alfredo sauce. Toss until everything is evenly coated.
  • Sprinkle the garlic powder over the mixture, then season with salt and freshly ground black pepper to taste. Add half of the mozzarella and all of the Parmesan. Gently fold to combine.
  • Lightly grease a 9×13-inch baking dish. Transfer the pasta mixture into the dish and spread it in an even layer. Sprinkle the remaining mozzarella over the top.

Baking and Serving

  • Bake for 20–25 minutes, or until the casserole is hot, bubbly, and the top is golden brown.
  • Remove from the oven and let rest for 5–10 minutes. If the sauce seems too thick, stir in reserved pasta water a little at a time until you reach the desired consistency. Serve warm.

Notes

Store leftovers in an airtight container for up to 3–4 days. Reheat in the microwave or gently in an oven. Can be frozen for up to 2 months. For variety, try adding protein like bacon or changing up the cheese types.
