The traditional version of this dish includes Swiss or Gruyère cheese, but you can also make it with other cheeses, such as mozzarella and cheddar in this recipe.
– Don’t be afraid to experiment with different cheeses. For example, sharp cheddar or Gruyère can add an extra depth of flavor. Other great options are Swiss or Gouda. For a smoky flavor, use smoked Gouda or cheddar.
