Chicken Broccoli Alfredo Bake is a creamy, cheesy, and comforting casserole made with tender pasta, juicy chicken, and fresh broccoli all coated in a rich homemade Alfredo sauce. It’s the perfect hearty meal for family dinners or potlucks.

Ingredients

  • 2 cups cooked chicken breast, shredded or cubed
  • 12 oz pasta (penne, rotini, or fettuccine)
  • 3 cups fresh or frozen broccoli florets
  • 3 tbsp butter
  • 3 cloves garlic, minced
  • 1 1/2 cups heavy cream or half-and-half
  • 1 cup grated Parmesan cheese
  • 1 cup shredded mozzarella cheese
  • 2 tbsp cream cheese (optional, for extra creaminess)
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • 1/2 tsp Italian seasoning
  • 1 tbsp chopped parsley (for garnish)

Instructions

  1. Preheat oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
  2. Cook pasta in salted boiling water until al dente. Add broccoli during the last 2 minutes of cooking. Drain and set aside.
  3. In a large skillet, melt butter over medium heat. Add minced garlic and cook for 30 seconds until fragrant.
  4. Pour in heavy cream and bring to a gentle simmer. Stir in Parmesan cheese until melted and smooth.
  5. (Optional) Add cream cheese for extra creaminess, stirring until fully incorporated.
  6. Season the sauce with salt, pepper, and Italian seasoning to taste.
  7. In a large mixing bowl, combine the cooked pasta, chicken, broccoli, and Alfredo sauce. Toss until evenly coated.
  8. Transfer the mixture into the prepared baking dish and top with shredded mozzarella cheese.
  9. Bake for 20–25 minutes, or until the cheese is melted and bubbly.
  10. Garnish with chopped parsley and serve warm.

Notes

  • Use rotisserie chicken for convenience and flavor.
  • Cook pasta just to al dente to prevent overcooking in the oven.
  • Thaw and drain frozen broccoli well before adding to the casserole.
  • For a crispy topping, mix breadcrumbs with melted butter and sprinkle on top before baking.
  • Add a pinch of red pepper flakes for a mild heat.
