Ingredients

Scale

Serves 6:

  • For the casserole:
    • 12 oz (340 g) pasta (penne, fettuccine, or rotini)
    • 2 cups (300 g) cooked chicken, shredded or diced
    • 2 cups (150 g) broccoli florets, steamed
    • 1 cup (100 g) shredded mozzarella cheese
    • 1/2 cup (50 g) grated Parmesan cheese
  • For the Alfredo sauce:
    • 3 tablespoons unsalted butter
    • 3 cloves garlic, minced
    • 2 tablespoons all-purpose flour
    • 2 cups (480 ml) heavy cream or whole milk
    • 1/2 cup (50 g) grated Parmesan cheese
    • 1/4 teaspoon ground nutmeg (optional)
    • Salt and black pepper, to taste

Instructions

  • Cook the pasta:
    • Preheat the oven to 375°F (190°C). Grease a 9×13-inch (23×33 cm) baking dish.
    • Bring a large pot of salted water to a boil. Cook the pasta according to package instructions until al dente. Drain and set aside.
  • Steam the broccoli:
    • Steam the broccoli florets until just tender (about 4-5 minutes). Set aside.
  • Prepare the Alfredo sauce:
    • In a medium saucepan, melt the butter over medium heat. Add the garlic and sauté for 1-2 minutes until fragrant.
    • Stir in the flour and cook for 1 minute, creating a roux. Gradually whisk in the cream, ensuring no lumps form.
    • Bring to a gentle simmer and cook until slightly thickened (about 3-4 minutes). Stir in Parmesan cheese, nutmeg (if using), salt, and pepper.
  • Assemble the casserole:
    • In a large bowl, combine the cooked pasta, chicken, broccoli, and Alfredo sauce. Mix until everything is evenly coated.
    • Pour the mixture into the prepared baking dish. Sprinkle the mozzarella and Parmesan cheese evenly on top.
  • Bake the casserole:
    • Bake in the preheated oven for 20-25 minutes, or until the top is golden and bubbly.
  • Serve:
    • Allow the casserole to cool for 5 minutes before serving. Garnish with chopped parsley if desired.

Notes

  • Use rotisserie chicken or leftover grilled chicken for convenience.
  • Add crispy bacon bits or red pepper flakes for extra flavor.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave before serving.
