Chicken Broccoli Ziti Alfredo Bake

Gather the ingredients. Preheat the oven to 375 F.

Spray a 9 x 13-inch baking dish with nonstick cooking spray and set aside.

Bring a large pot of water to a boil and add some salt.

Cook the pasta in the water for 1 minute less than the recommended cooking time. Drain and set aside.

Meanwhile, in a large skillet, melt the butter over medium heat. Add the onion and garlic; cook and stir until tender, about 6 to 8 minutes.

Add the Alfredo sauce and bring to a simmer. Take the pan off the heat and stir in the havarti or cheddar cheese until melted.

Stir in the cooked and drained pasta, the broccoli, and the chicken into the sauce mixture until combined.

Pour into the prepared pan and sprinkle with the Parmesan cheese. Bake the casserole at 375 F for 45 to 55 minutes or until the mixture is bubbly and cheese on top begins to brown.

Serve and enjoy.
