Recipe FAQ

Can I substitute the cheddar cheese?

Yes, Gruyère cheese is an excellent alternative for a richer, nutty flavor. It melts smoothly and complements the potatoes well.

What type of potatoes works best?

Russet potatoes are ideal due to their starchy texture, which helps absorb the creamy sauce and bake nicely.

Is it necessary to use both milk and cream?

Combining milk and heavy cream strikes a balance between richness and smoothness, creating the velvety texture of the sauce.

Can I prepare this in advance?

Yes, you can assemble the layers ahead of time and refrigerate before baking. Just add extra baking time if baking from cold.

How can I add more flavor to the dish?

Adding a pinch of smoked paprika or substituting different herbs like thyme or rosemary can enhance the savory depth of the casserole.
