Ingredients
  

Pasta and Chicken

  • 12 oz pasta (penne, rigatoni, or your favorite) Use gluten-free pasta for a gluten-free version.
  • 2 cups cooked shredded chicken (rotisserie-style or poached) Rotisserie chicken is a great shortcut.

Sauce Ingredients

  • 3 cups Alfredo sauce (homemade or store-bought) Pre-made sauces may be salty; check and adjust seasoning.
  • 1 cup low-sodium chicken broth
  • 1 1/2 cups shredded mozzarella Reserve half for topping.
  • 1/2 cup grated Parmesan Reserve half for topping.
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 2 tbsp olive oil
  • 1 cup frozen peas or steamed broccoli florets (optional) Can be replaced with other vegetables if desired.
  • 1 tsp dried Italian seasoning
  • 1/4 tsp red pepper flakes (optional)
  • Salt and black pepper to taste
  • Fresh parsley for garnish

Instructions
 

Preparation

  • Preheat oven to 375°F (190°C). Grease a 9x13-inch baking dish.
  • Bring a large pot of salted water to a boil and cook pasta 1–2 minutes less than package directions. Drain and set aside.

Cooking

  • In a skillet, heat olive oil over medium heat. Add onions and cook until translucent, about 4–5 minutes. Add garlic and cook for an additional 30 seconds until fragrant.
  • Stir in Alfredo sauce and chicken broth; warm gently. Add Italian seasoning, red pepper flakes, salt, and pepper. If your shredded chicken needs moisture, stir it into the sauce now.

Assembly

  • In a large bowl, combine cooked pasta with the sauce-chicken mixture, and add frozen peas or broccoli if using. Mix in half of the mozzarella and half of the Parmesan, reserving the rest for topping.
  • Pour the mixture into the prepared baking dish, smooth the top, and evenly sprinkle the remaining mozzarella and Parmesan.

Baking

  • Bake uncovered for 20–25 minutes until bubbling and the cheese is golden. For a crispier top, broil for 2–3 minutes while watching closely.
  • Let the Chicken Alfredo Pasta Bake rest for 5–10 minutes before serving to set. Garnish with chopped parsley.

Notes

Don’t overcook the pasta. Use warm sauce for mixing and control the salt in pre-made sauces. Consider adding sautéed mushrooms or caramelized onions for texture.
