Description

This Chicken and Broccoli Alfredo Bake is a creamy, comforting casserole perfect for a family dinner. Tender pasta and fresh broccoli are combined with shredded rotisserie chicken and a rich Alfredo sauce, then topped with mozzarella and parmesan cheese before baking to bubbly perfection. It’s an easy, satisfying one-dish meal that brings the classic flavors of Alfredo pasta to your oven.


Ingredients

Scale

Pasta and Vegetables

  • 8 ounces uncooked penne pasta
  • 4 cups broccoli florets

Protein and Sauce

  • 2 cups cooked chicken, shredded or chopped (rotisserie recommended)
  • 1 (15 ounce) jar Alfredo sauce
  • 1/2 teaspoon Italian seasoning

Cheese and Seasoning

  • 1/2 cup freshly grated parmesan cheese
  • 2 cups shredded mozzarella cheese
  • Salt and pepper to taste


Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C) and position the oven rack in the top third of the oven to ensure even baking and browning of the cheese topping.
  2. Cook Pasta and Broccoli: Boil a large pot of salted water. Add the pasta and cook it for one minute less than the package instructions. Two minutes before the pasta finishes cooking, add the broccoli florets to the same pot. Drain both together once done and transfer them to a 9×13-inch casserole dish.
  3. Combine Ingredients: Add the shredded cooked chicken, Alfredo sauce, grated parmesan cheese, and Italian seasoning into the casserole dish with the pasta and broccoli. Toss everything thoroughly to combine and evenly coat all ingredients with the sauce.
  4. Layer and Top: Spread the mixture out into an even layer in the dish. Sprinkle the shredded mozzarella cheese evenly over the top to create a delicious cheesy crust when baked.
  5. Bake and Serve: Bake uncovered for 15-20 minutes until the casserole is hot and bubbly. For a golden brown cheese top, optionally broil the bake for a few minutes—watch carefully to prevent burning. Season with salt and pepper as needed and serve immediately for a warm, comforting meal.

Notes

  • Using fresh broccoli florets ensures tenderness and flavor, but frozen broccoli can be used as a substitute—thawed and drained.
  • Rotisserie chicken is a convenient option that adds great flavor and reduces prep time.
  • Be sure not to overcook the pasta initially since it will continue cooking in the oven.
  • Broiling at the end is optional but adds a nice golden crust to the cheese topping.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
