Ingredients
  

For the Dish
  • 4 tablespoons softened unsalted butter (divided) 2 tablespoons for greasing the baking dish, 2 tablespoons for topping
  • 3 pounds russet potatoes (peeled) About 4 or 5 medium potatoes
  • 1 cup heavy cream
  • 1/2 cup shredded white cheddar cheese
  • 6 tablespoons grated Parmesan (divided) 4 tablespoons mixed in, 2 tablespoons for topping
  • 3 cloves garlic (minced)
  • Salt and pepper to taste For seasoning

Method
 

Preparation
  1. Preheat oven to 375˚F. Grease a baking dish with 2 tablespoons butter.
  2. Very thinly slice the potatoes using a mandolin.
  3. In a large mixing bowl, combine cream, shredded cheddar, 4 tablespoons Parmesan, and minced garlic.
  4. Add sliced potatoes and toss together until the potatoes are well-coated. Season generously with salt and pepper.
Assembly
  1. Take a stack of potatoes and line the baking dish, keeping potatoes upright. Repeat until all potatoes are used.
  2. Evenly pour excess cream mixture over potatoes and lightly season with salt and pepper.
  3. Dot the top with remaining 2 tablespoons of butter.
Baking
  1. Cover the baking dish with foil and bake for 35 to 40 minutes.
  2. Remove from oven, uncover, and sprinkle the top with remaining Parmesan. Continue to bake for an additional 25 to 30 minutes or until potatoes are fork tender.
  3. Transfer to a broiler and broil on high for 1 minute, until the top has browned.
  4. Remove from oven and cool for about 10 minutes before serving.

Notes

Use a mandolin for even slices. Experiment with different cheeses like Gruyère or mozzarella. Let the dish sit for a few minutes after baking to settle the layers.
