Recipe Q&A

How do I achieve the perfect sauce consistency?

Gradually whisk milk and cream into the roux over medium heat, stirring constantly until thickened to a smooth, creamy texture.

Can I substitute the chicken with another protein?

Yes, cooked rotisserie chicken works well or you can use turkey or sautéed mushrooms for a vegetarian twist.

What pasta type works best for this dish?

Fettuccine is ideal for holding the creamy sauce, but other flat pastas like linguine can be used as well.

How to get a crispy cheesy topping?

Bake until bubbly and golden, then broil for 2-3 minutes to achieve a crisp, browned cheese crust.
