Chicken alfredo bake takes all the creamy, garlicky goodness of classic fettuccine alfredo and transforms it into the ultimate comfort food casserole. Tender chicken, pasta, and a rich, homemade alfredo sauce are baked together until bubbly, then topped with a generous blanket of melted mozzarella and Parmesan.
It’s the kind of dish that feeds a crowd, satisfies the deepest cravings, and disappears fast. Perfect for family dinners, potlucks, or anytime you need a little comfort.
Preheat and Prep
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish.
Cook the Pasta
Bring a large pot of salted water to a boil. Cook the pasta according to package directions until 1-2 minutes less than al dente (it will finish cooking in the oven). Drain and set aside.
Cook the Chicken
While the pasta cooks, heat the olive oil in a large skillet over medium-high heat. Season the chicken pieces with salt and pepper. Add to the skillet and cook until golden brown and cooked through, about 5-7 minutes. Add the minced garlic and cook for 1 minute until fragrant. Remove chicken and garlic to a plate and set aside.
Make the Alfredo Sauce
In the same skillet, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes until golden and bubbly (making a roux). Gradually whisk in the heavy cream and chicken broth, stirring constantly until smooth.
Bring to a simmer and cook until thickened, about 3-5 minutes. Remove from heat and stir in the grated Parmesan cheese and nutmeg until smooth. Season with salt and pepper to taste.
Combine
In a large bowl, combine the cooked pasta, chicken, and Alfredo sauce. Stir until everything is well coated.
Transfer to Baking Dish
Pour the mixture into the prepared baking dish and spread evenly.
Add Cheese Topping
Sprinkle the shredded mozzarella evenly over the top.
Bake
Bake for 20-25 minutes, until the sauce is bubbly and the cheese is melted and golden brown. For extra browning, broil for 1-2 minutes at the end.
Rest and Serve
Let the bake rest for 5-10 minutes before serving. Garnish with fresh parsley.
Pro-Tips for Chicken Alfredo Bake Perfection
- Undercook the Pasta: Cook it 1-2 minutes less than package directions—it will absorb sauce and finish cooking in the oven.
- Use Freshly Grated Parmesan: Pre-grated cheese won’t melt as smoothly.
- Don’t Skip the Roux: The flour and butter roux thickens the sauce perfectly.
- Season Well: Alfredo sauce needs plenty of salt and pepper to bring out the flavors.
- Add Veggies: Broccoli, spinach, or mushrooms make great additions.
- Make Ahead: Assemble the bake up to 24 hours ahead, cover, and refrigerate. Add 10-15 minutes to baking time.
- Freezer Friendly: This bake freezes beautifully. Cool completely, wrap tightly, and freeze for up to 3 months.
- Leftovers: Reheat gently in the oven or microwave with a splash of milk to refresh the sauce.
This Chicken Alfredo Bake is creamy, cheesy, and absolutely comforting.
