Ingredients

  • Pasta and Proteins: 12 oz (340 g) fettuccine pasta, 2 cups (about 300 g) cooked chicken breast, diced or shredded
  • Sauce: 4 tbsp (60 g) unsalted butter, 3 cloves garlic, minced, 1/4 cup (30 g) all-purpose flour, 3 cups (720 ml) whole milk, 1 cup (240 ml) heavy cream, 1 1/2 cups (150 g) freshly grated Parmesan cheese, 1/2 tsp salt, 1/2 tsp black pepper, 1/4 tsp ground nutmeg (optional)
  • Topping: 1 cup (115 g) shredded mozzarella cheese, 1/2 cup (50 g) freshly grated Parmesan cheese, 2 tbsp chopped fresh parsley (optional)

Instructions

Prep Oven:
Preheat the oven to 375°F (190°C). Grease a 9x13-inch (23x33 cm) baking dish.
Cook Pasta:
Cook the fettuccine in a large pot of salted boiling water until al dente. Drain and set aside.
Make Sauce:
In a large saucepan over medium heat, melt the butter. Add garlic and sauté for 1 minute until fragrant. Whisk in the flour and cook for 1–2 minutes to form a roux. Gradually whisk in the milk and cream, stirring constantly until the mixture thickens, about 4–5 minutes. Stir in Parmesan, salt, pepper, and nutmeg until the cheese is melted and the sauce is smooth.
Combine:
Add the cooked chicken and drained pasta to the sauce. Toss until evenly coated.
Bake:
Transfer the mixture to the prepared baking dish. Sprinkle mozzarella and Parmesan evenly over the top. Bake for 20–25 minutes until bubbly and golden. If desired, broil for 2–3 minutes for a crisper top.
Finish:
Let stand for 5 minutes before garnishing with fresh parsley and serving.

Cook the fettuccine just until al dente before mixing with the sauce, as it will continue to cook in the oven to achieve the perfect texture.

What can I add for extra flavor or vegetables?

Sautéed mushrooms or fresh spinach can be stirred into the sauce before baking to enhance flavor and nutrition.

Can I make this with gluten-free pasta and flour?
