  • Sprinkle half of the Gruyère and Parmesan cheese over the potatoes.
  • Add another layer of the remaining potatoes and then the remaining cheese.
  • Pour the cream mixture evenly over the layers.
  • Cover with aluminum foil (shiny side down) and bake for about 40 minutes.

Notes

Use starchy potatoes like russets for the best texture. Cheese substitutions can include Emmental or sharp cheddar. Layer carefully to avoid mushiness, and you can prepare layers ahead of time. Leftovers can be refrigerated for up to 3 days or frozen for up to a month.
