Recipe FAQ

What type of potatoes work best?

Yukon Gold or Russet potatoes are ideal due to their texture and ability to hold layers well without becoming mushy.

Can I substitute the cheeses used?

Gruyère can be swapped with Swiss or Monterey Jack, while sharp cheddar adds a robust flavor; blending these maintains the creamy texture.

How do I achieve a smooth cheese sauce?

Make a roux with butter and flour, then slowly whisk in warm milk and cream to avoid lumps before adding cheeses for a velvety sauce.

Is it necessary to cover the dish while baking?

Covering with foil during most of the baking ensures tender potatoes and prevents the top from over-browning; then uncover to brown the cheese topping.

What seasoning enhances the flavor?

Dijon mustard, smoked paprika, salt, and pepper add layers of subtle heat and depth that complement the richness of the cheese sauce.
