Save A creamy, comforting casserole featuring tender chicken, fettuccine pasta, and a rich Alfredo sauce, baked to golden perfection with a cheesy topping.
I first made this Chicken Fettuccine Alfredo Bake when my family was craving something heartwarming but simple. The aroma of bubbling cheese in the oven always brings us together in anticipation for dinner.
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.
