Substitutions
Use all cheddar instead of Gruyère. A gluten-free flour blend, pasta, and crumbs can be used together.
Practical tip
Shred cheese from a block for a smoother sauce, and avoid overcooking the pasta before baking.
Storage and reheating
Refrigerate for up to 4 days. Reheat covered to 165°F (74°C), uncovering briefly to crisp the top.
