Ingredients

Scale

Potatoes

  • 1 to 1 1/2 lbs. Yukon gold potatoes, peeled and sliced thinly

Sauce & Seasoning

  • 1 stick unsalted butter
  • 34 cloves garlic, minced or sliced
  • 3/4 cup heavy cream or milk
  • 1 cup freshly grated parmesan cheese
  • Salt and pepper, to taste

Garnish

  • Fresh thyme or oregano, for garnish

Instructions

  1. Preheat Oven and Prepare Dish: Preheat your oven to 375°F (190°C). Grease a baking dish thoroughly and set it aside, ensuring the potatoes won’t stick during baking.
  2. Make Garlic Parmesan Cream Sauce: Heat a small saucepan over medium-high heat. Add the butter and minced or sliced garlic, sautéing for 4-5 minutes until the garlic becomes fragrant. Remove from heat, then stir in the heavy cream (or milk) and freshly grated parmesan cheese until the cheese melts completely. Season this creamy sauce with salt and pepper to taste.
  3. Combine Potatoes with Sauce: Place the thinly sliced potatoes in a large mixing bowl. Pour the prepared cream and cheese mixture over the potatoes and gently toss to coat all slices evenly.
  4. Assemble and Bake: Arrange the coated potato slices evenly in the greased baking dish. Pour any remaining cream mixture over the top. Bake in the preheated oven for 55-60 minutes, or until the potatoes are tender and the top is golden brown and bubbly.
  5. Garnish and Serve: Once baked, optionally garnish with fresh thyme or oregano leaves and serve warm. Enjoy your creamy, flavorful Potato Au Gratin!

Notes

  • Yukon gold potatoes are preferred for their creamy texture and ability to hold their shape; avoid starchy or waxy varieties for best results.
  • Using heavy cream yields a richer sauce, but milk can be substituted for a lighter option.
  • Make sure to slice potatoes thinly and evenly to ensure thorough and even cooking.
  • Freshly grated parmesan cheese melts better and has more flavor than pre-grated varieties.
  • For a crispier top, you can broil the dish for 2-3 minutes after baking, watching carefully to avoid burning.
