Recipe FAQ

What type of pasta is best for this dish?

Fettuccine pasta works best as it holds the creamy sauce well and provides a satisfying texture.

How can I make the Alfredo sauce thicker?

Cooking the roux (butter and flour) properly before gradually adding milk and cream helps thicken the sauce to a smooth consistency.

Can I use pre-cooked or rotisserie chicken?

Yes, using pre-cooked or rotisserie chicken is a convenient option that still delivers great flavor.

What are good topping options besides mozzarella and Parmesan?

Additional toppings like sautéed mushrooms, spinach, or extra Parmesan add flavor and texture variety.

How long should I bake to achieve a golden crust?

Bake for 20-25 minutes until bubbly, then broil 2-3 minutes for a crisp, golden cheese topping.
