Ingredients:

  • 3 lbs Yukon Gold potatoes
  • 1 medium yellow onion, sliced into paper-thin rings
  • 2 cups heavy whipping cream
  • 1 cup whole milk
  • 4 cloves garlic, smashed and peeled
  • 1 tsp fresh thyme leaves
  • 1.5 tsp sea salt
  • 0.5 tsp cracked black pepper
  • 0.25 tsp nutmeg
  • 1.5 cups sharp cheddar cheese, shredded
  • 0.5 cup Gruyère cheese, shredded
  • 0.5 cup Parmesan cheese, finely grated

Instructions:

  1. Infuse the dairy. In a small saucepan over medium heat, combine 2 cups heavy whipping cream, 1 cup whole milk, 4 smashed garlic cloves, 1 tsp thyme, 1.5 tsp sea salt, 0.5 tsp pepper, and 0.25 tsp nutmeg. Note: Heating the dairy first ensures the potatoes start cooking the moment they hit the oven.
  2. Simmer and steep. Bring the mixture to a gentle simmer until tiny bubbles form around the edges. Remove from heat and let sit for 10 minutes to steep the aromatics.
  3. Prepare the oven. Preheat your oven to 180°C (350°F) and grease your 9x13 inch baking dish generously with butter.
  4. Strain the cream. Pour the infused mixture through a fine mesh strainer into a bowl, discarding the solids.
  5. Layer the base. Arrange one third of the sliced potatoes in an overlapping pattern. Note: Overlapping ensures there are no large gaps for the sauce to pool in.
  6. Add aromatics and cheese. Scatter half of the sliced onions and one third of the cheddar and Gruyère blend over the potatoes.
  7. Repeat the process. Create two more layers of potatoes, onions, and cheese, ending with a final layer of potatoes on top.
  8. Drown in cream. Carefully pour the warm, infused cream over the layers until the liquid sits just below the top potatoes.
  9. The first bake. Cover the dish tightly with foil and bake for 45 minutes at 180°C.
  10. The golden finish. Remove the foil, sprinkle with the remaining cheese and Parmesan, and bake for another 20 minutes until the top is bubbling and deep golden brown. > Chef's Tip: If you want an extra crispy top, turn on the broiler for the last 2 minutes of cooking.
