Ingredients
  

  • 3 tablespoons unsalted butter
  • 3 tablespoons all-purpose flour
  • 1/2 cup chopped sweet yellow onion
  • 2 cloves garlic, finely minced
  • 2 cups whole milk, preferably warmed
  • 1/2 cup heavy cream
  • 1 1/2 teaspoons fine sea salt adjust to taste
  • 1/4 teaspoon freshly cracked white or black pepper
  • 2 teaspoons Dijon mustard
  • 1/4 teaspoon ground nutmeg
  • 1 1/2 cups freshly shredded sharp Cheddar cheese mix half Gruyère and half Emmentaler for a gourmet touch
  • 1/3 cup finely grated Parmesan cheese for layering and topping
  • 2 pounds thinly sliced medium-starch potatoes Yukon Golds or Russets
  • Freshly chopped flat-leaf parsley for garnish

Method
 

Step 1: Prepare the Potatoes
  1. Start by preheating your oven to 375°F (190°C). Wash and peel the potatoes, then slice them thinly—about 1/8 inch thick. A mandoline works beautifully for this task. Aim for uniform slices to ensure even cooking.
Step 2: Make the Roux
  1. In a medium saucepan, melt the butter over medium heat. Once melted, whisk in the flour. Cook for about 2 minutes until it forms a paste, but don’t let it brown! Stir continually to create a smooth roux that will thicken the sauce.
Step 3: Create the Cheese Sauce
  1. Slowly add the warmed milk to the roux while whisking vigorously to avoid lumps. Stir in the heavy cream. Keep cooking until the mixture thickens and coats the back of a spoon, about 5-7 minutes. Season it with salt, pepper, Dijon mustard, and nutmeg. Afterward, add in the freshly shredded cheese gradually, stirring until melted and smooth.
Step 4: Assemble the Dish
  1. In a greased baking dish, layer half of the sliced potatoes. Pour half of the cheese sauce over the potatoes. Layer the remaining potatoes on top and finish with the rest of the cheese sauce. Make sure the sauce fully covers the potatoes for even cooking.
Step 5: Add Parmesan and Bake
  1. Sprinkle the grated Parmesan on top. Cover the dish with aluminum foil and bake in the preheated oven for about 45 minutes. After this time, remove the foil and bake for an additional 30-45 minutes until bubbly and golden. The top should be a delightful golden-brown.
Step 6: Rest and Serve
  1. Once cooked, let the dish rest for about 15 minutes before serving. This allows flavors to meld together. Garnish with freshly chopped parsley for a touch of freshness.

Notes

  • Use Fresh Cheese: Opt for freshly shredded cheese instead of pre-shredded varieties. The anti-caking agents in pre-packaged cheese can hinder the melt quality.
  • Layer Wisely: Ensure each layer of potatoes is coated in cheese sauce for maximum flavor in every bite.
  • Don’t Rush: Allow the dish to rest after baking to ensure it holds its shape when served.
  • Experiment with Potatoes: While Yukon Golds are classic, Russets work wonderfully as they’re starchier and absorb flavors better.
  • Add Herbs: For a fresh twist, consider adding thyme or rosemary to the cheese sauce. It brightens the dish nicely.
