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 for a family dinner when everyone craved something indulgent and heartwarming. It quickly became a favorite thanks to its creamy sauce and cheesy topping.
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 & Dish:
- Preheat oven to 375°F (190°C). Grease a 9x13-inch (23x33 cm) baking dish.
- Cook Pasta:
- Cook fettuccine in a large pot of salted boiling water until al dente. Drain and set aside.
- Make Alfredo Sauce:
- Melt butter in a saucepan over medium heat. Add garlic and cook 1 minute until fragrant. Whisk in flour and cook 1–2 minutes to form roux. Slowly whisk in milk and cream, stirring until thick, about 4–5 minutes. Stir in Parmesan, salt, pepper, and nutmeg until sauce is smooth.
- Combine Chicken & Pasta:
- Add cooked chicken and drained pasta to sauce. Toss until evenly coated.
- Assemble & Bake:
- Transfer mixture to prepared baking dish. Sprinkle mozzarella and Parmesan evenly on top. Bake 20–25 minutes until bubbly and golden. Broil 2–3 minutes for a crisper top if desired. Let stand 5 minutes, garnish with parsley, and serve.

Recipe Guide
- → Can I use rotisserie chicken instead of cooked chicken breast?
Yes, rotisserie chicken works well and can save preparation time without sacrificing flavor.
- → What pasta is best for this dish?
Fettuccine is ideal as it holds the creamy sauce well, but similar pasta shapes like tagliatelle or pappardelle also work.

The sauce thickens by cooking a butter and flour roux, then gradually whisking in milk and cream until smooth and rich.
- → Can I add vegetables to the casserole?
Yes, adding sautéed mushrooms or spinach enhances flavor and adds texture.
- → What is the best way to get a crispy cheese topping?
Baking the casserole until bubbly and golden followed by a quick broil for 2–3 minutes will create a crisp, flavorful crust.
