Ingredients

Scale

Cheese Mix

1 1/2 cups grated mild Gruyere cheese
1/2 cup grated medium Gruyere cheese (optional)
1 cup grated Fontina cheese
1/4 cup grated Parmesan Reggiano cheese

Potatoes and Other Ingredients

4–5 Yukon Gold potatoes, peeled and sliced thin
1 cup milk
2 tablespoons melted butter
2 cloves fresh garlic, minced
Salt & pepper to taste

Instructions

Preheat Oven: Preheat your oven to 425°F (218°C) and prepare an 8×8 inch baking dish or similar size for layering your potatoes and cheese.
First Potato Layer: Arrange an even layer of thinly sliced potatoes at the bottom of the baking dish, slightly overlapping the edges. Sprinkle with salt and pepper. Then evenly distribute a handful of mild Gruyere cheese, followed by some medium Gruyere (if using), and a handful of Fontina cheese.
Second Potato Layer With Butter: Repeat the layering as before: potatoes, salt, pepper, mild Gruyere, optional medium Gruyere, and Fontina. Drizzle 1 tablespoon of melted butter evenly over this layer to ensure richness.
Continue Layering: Repeat the layering process (as in steps 2 and 3) until the dish is filled just to the rim. Only the second layer and one additional layer receive drizzled butter; others do not.
Top with Parmesan: After finishing the layers, sprinkle the grated Parmesan Reggiano generously over the top for a golden finish.
Prepare Garlic Milk: In a small saucepan, bring the milk to a gentle simmer until steam rises, then remove from heat. Stir in minced garlic thoroughly to infuse flavor into the milk.
Pour Milk Over Potatoes: Carefully pour the hot garlic-infused milk over the layered potatoes and cheese in the baking dish, ensuring it distributes evenly.
Bake: Place the baking dish in the preheated oven and bake for 40 minutes until the top is golden brown and the potatoes are tender when pierced with a fork.

Notes

You can use a 9×13 baking dish if preferred, but you may need additional potatoes and cheese to fill the larger size.
Use a mandoline slicer or a sharp knife to ensure uniformly thin potato slices for even cooking.
For extra creaminess, you can substitute whole milk with half-and-half or add a splash of heavy cream.
The medium Gruyere cheese is optional but contributes a richer flavor profile.
Allow the dish to rest for 5-10 minutes after baking for easier serving and better layered texture.
