Ingredients

8 ounces uncooked pasta (penne works well)
4 cups broccoli florets
2 cups cooked chicken (rotisserie chicken, shredded or chopped)
1 (15-ounce) jar Alfredo sauce
1/2 teaspoon Italian seasoning
1/2 cup freshly grated Parmesan cheese
2 cups shredded mozzarella cheese
Salt and pepper, to taste

Instructions

Preheat the oven to 375°F and position the oven rack in the upper third.
Bring a large pot of salted water to a boil. Cook the pasta for one minute less than the package instructions. Add the broccoli florets to the boiling water during the last 2 minutes of cooking. Drain both and transfer to a 9×13-inch casserole dish.
Add the cooked chicken, Alfredo sauce, Parmesan cheese, and Italian seasoning to the casserole dish. Toss everything together until well combined.
Spread the mixture evenly in the dish, then sprinkle the shredded mozzarella cheese over the top.
Bake uncovered for 15-20 minutes, or until the dish is hot and bubbly. For a golden cheese topping, broil for 1-2 minutes—watch closely to avoid burning.
Season with salt and pepper as needed before serving immediately.
