Ingredients
  

  • 2½ lbs Russet potatoes peeled and thinly sliced
  • 2 cups sharp cheddar cheese freshly shredded
  • ½ cup Parmesan cheese finely grated
  • 1½ cups heavy cream
  • 1 cup whole milk
  • 4 tablespoons unsalted butter
  • 3 tablespoons all-purpose flour
  • 3 garlic cloves minced
  • Salt and freshly ground black pepper to taste
  • Fresh thyme or parsley optional, for garnish

Instructions
 

Preheat Oven & Prepare Dish

  • Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking or casserole dish with butter.

Make the Creamy Sauce

  • In a saucepan, melt 4 tablespoons of butter over medium heat. Stir in 3 tablespoons of flour and whisk constantly for 1 minute to create a smooth roux.
  • Add minced garlic and cook for 30 seconds. Gradually whisk in the heavy cream and milk until smooth. Simmer for 3–4 minutes until slightly thickened.
  • Remove from heat and stir in 1 cup cheddar and all the Parmesan. Season with salt and pepper to taste.

Layer the Potatoes

  • Spread a thin layer of sauce on the bottom of the baking dish.
  • Arrange a layer of sliced potatoes, slightly overlapping. Spoon over some sauce, then sprinkle with cheddar.
  • Repeat the layers until all ingredients are used, finishing with sauce and remaining cheddar on top.

Bake

  • Cover tightly with foil and bake for 40 minutes. Remove the foil and bake another 20–25 minutes until the top is golden and bubbly and the potatoes are fork-tender.

Optional Broil

  • For a crispier top, broil uncovered for 2–3 minutes—keep a close eye to prevent burning.

Cool & Serve

  • Let rest for 10 minutes before serving to allow the layers to set. Garnish with fresh thyme or parsley, if desired.
