Method
 

Step‑by‑Step Instructions
  1. Preheat your oven to 325°F (160°C).
  2. In a medium saucepan, combine heavy cream, kosher salt, and minced garlic. Bring to a gentle simmer over medium heat for about 5 minutes.
  3. Using a mandoline slicer, thinly slice the Yukon Gold potatoes to about 1/8 inch thick, and place them in cold water.
  4. In a skillet, melt a tablespoon of butter over medium heat, add the diced shallots and sauté until caramelized, about 5 minutes.
  5. Arrange the potato slices in a spiral pattern over the shallots, and pour the cream mixture evenly over the potatoes.
  6. Cover the skillet tightly with aluminum foil and bake for 1 hour and 15 minutes, until the potatoes are tender.
  7. Uncover, sprinkle with Gruyere and Parmesan, and broil for about 5 minutes until golden brown.
  8. Let the gratin cool slightly for about 5 minutes before serving.
