Ingredients
  

Main ingredients
  • 4 large potatoes, peeled and thinly sliced Yukon Gold or Russet work well; waxier potatoes like Red keep firmer slices.
  • 2 cups heavy cream Substitute: half-and-half for lighter but expect a looser finish.
  • 2 cups grated cheese, such as Gruyère or Cheddar Gruyère gives nuttier flavor; mix in Parmesan for extra umami.
  • 3 cloves garlic, minced Or 1–2 tsp jarred roasted garlic.
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon nutmeg Freshly grated if possible.
  • 2 tablespoons butter Dotted on top before baking.
Notes/Substitutions
  • For a dairy-free version, use a full-fat coconut milk or a cashew cream (texture and flavor will differ).
  • To add herbs, tuck a few thyme sprigs between layers or sprinkle 1 tsp dried thyme into the cream.

Method
 

Preparation
  1. Preheat your oven to 375°F (190°C). Grease a medium baking dish (about 8x8 or 9x13 depending on serving size).
  2. Gently heat the heavy cream in a small saucepan over low heat. Add the minced garlic, salt, pepper, and nutmeg. Warm until fragrant but do not boil.
  3. Arrange half of the thin potato slices in an even layer in the prepared dish. Pour half of the warm cream evenly over the potatoes and sprinkle half of the grated cheese.
  4. Repeat with the remaining potatoes, pouring the rest of the cream and topping with the remaining cheese.
  5. Dot the surface with small pieces of butter to encourage browning and a glossy finish.
Cooking
  1. Cover the dish tightly with foil and bake for 45 minutes.
  2. Remove the foil and continue baking for 20–30 minutes until the top is golden brown and bubbling.
  3. If you want extra crunch, place under a broiler for 1–2 minutes while watching closely.
Resting
  1. Let the gratin rest for 10–15 minutes before slicing.
