Use a slotted spoon, to transfer one-third of the potato mixture into the prepared dish. Sprinkle with one-third of
Gruyère Cheese (170 g)

Step 6
After layering the potatoes and cheese, drizzle the liquid over the top, letting it seep down into the dish. Loosely cover the dish with parchment and then cover with foil that has been sprayed with nonstick cooking spray.

Remove foil and parchment; turn oven to broil. Broil until potatoes are bubbly and browned in places, 3 to 5 minutes.
