Let’s Build This Layered Masterpiece

Now let’s dive into the cooking process. Here are the steps you are going to follow.

1. Preheat Your Equipment: Preheat your oven to 375 degrees Fahrenheit and lightly butter a 9×13 inch baking dish.
2. Combine Ingredients: In a saucepan over medium heat, warm heavy cream, whole milk, minced garlic, salt, black pepper, and thyme until just heated through, do not boil.
3. Prepare Your Cooking Vessel: Arrange a layer of sliced potatoes evenly in the buttered baking dish.
4. Assemble the Dish: Pour a portion of the warm cream mixture over the potatoes, then sprinkle a layer of cheddar and Gruyere. Repeat layering potatoes, cream, and cheese until all ingredients are used, finishing with cheese on top.
5. Cook to Perfection: Cover with foil and bake for 45 minutes. Remove foil and bake an additional 20 to 25 minutes until the top is golden and the potatoes are tender when pierced with a knife.
6. Finishing Touches: Let the dish rest for 10 minutes to allow the layers to settle and thicken slightly.
7. Serve and Enjoy: Slice into squares and serve warm while the cheese is still beautifully melted.

As it bakes, the cream thickens and weaves through each layer. The potatoes become tender but hold their shape, and the cheese melts into a golden crust that gives a slight crisp bite before yielding to the creamy interior. The garlic and thyme gently perfume every forkful. Let me tell you, it’s worth every bite.
