Instead of layering, I sauteed the onions and then mixed them into the sauce, along with the cheese. Poured over the potatoes in a 2 qt. baking dish once it was melted and baked until bubbly. Delicious!
Gruyère cheese is known for its rich, nutty flavor. Some would call it a stinky cheese. You can also substitute Swiss or Cheddar cheese.
