Peel the potatoes and slice them. Preferably use a mandoline slicer.

Then put them in a pot and boil for approximately 10 minutes in lightly salted water.

Next, pour the potatoes into an oven-safe dish and cover them with your favorite Bearnaise sauce. It must be a store-bought Bearnaise, as a homemade sauce will separate in the oven.

Finally, crumble buffalo mozzarella over the Bearnaise.

Place the dish in the oven at 200 degrees Celsius (392 degrees Fahrenheit) (fan).

Cook until the cheese is golden. This takes approximately 25-30 minutes.

Remove from the oven and let it rest for 5 minutes before serving.
