Ingredients You’ll Need:

  • Heavy Cream: 1 1/2 cups to create a lusciously smooth sauce.
  • Kosher Salt: 2 tsp to enhance the flavors.
  • Garlic: 3 cloves, minced, infusing the cream with aromatic depth.
  • Butter: 1 tbsp for sautéing the shallot.
  • Shallot: 1 small, diced, adding a subtle sweetness.
  • Potatoes: 5 medium Yukon Gold or White, thinly sliced for delicate layers.
  • Gruyere Cheese: 1 cup, grated, for a nutty, earthy taste.
  • Parmesan Cheese: 1/2 cup, grated, to achieve a crispy, golden top.
  • Fresh Thyme: 1 tsp to add a hint of herbaceous freshness.

Directions to Culinary Bliss:

  1. Preheat and Prep: Begin by setting your oven to 325°F (165°C), a gentle heat to cook the gratin evenly and thoroughly.
  2. Infuse the Cream: In a small saucepan, combine the heavy cream, kosher salt, and minced garlic. Simmer on low heat for 5 minutes. This step is crucial for infusing the cream with a rich garlic flavor. Afterward, remove from heat and set aside.
  3. Slice the Potatoes: Using a mandoline slicer, thinly slice the potatoes to a thickness of 1/8 inch. This ensures each potato slice cooks evenly, becoming perfectly tender.
  4. Caramelize the Shallots: Melt butter in a 12-inch cast-iron pan over low heat. Add the diced shallots, frying them until caramelized, about 5 minutes. This foundation of flavor sets the stage for the layers above.
  5. Layer and Bake: Arrange the potato slices in a spiral pattern over the shallots, then pour the infused cream over the top. Cover the pan with foil and bake for 1 hour and 15 minutes, allowing the potatoes to soak up the creamy goodness.
  6. Broil to Perfection: Remove the foil, increase the oven temperature to broil, and sprinkle the gratin with grated Gruyere, Parmesan, and thyme. Broil for 5 minutes, or until the cheese is irresistibly crispy and bubbling.
  7. Serve Warm: Let it stand for a few minutes after broiling, then serve warm, diving into the layers of creamy potatoes and crispy, cheesy topping.
