Potatoes

  • 3 lbs Potatoes Starchy potatoes like Russet or Yukon Gold, peeled and thinly sliced
  • 2 cups Milk Whole milk preferred, but 2% or skim can be used
  • 1 cup Heavy Cream Adds luxurious texture, can substitute with half-and-half
  • ¼ cup Unsalted Butter Essential for the roux and richness
  • ¼ cup All-Purpose Flour For thickening the sauce
  • 1 medium Onion Finely chopped
  • 2 cloves Garlic Minced
  • 2 cups Sharp Cheddar Cheese Grated, can use pre-shredded
  • ½ cup Parmesan Cheese Grated, freshly grated preferred
  • ¼ teaspoon Nutmeg Ground
  • 1 teaspoon Dried Thyme
  • to taste Salt
  • to taste Black Pepper Freshly ground recommended
  • Fresh Parsley Optional, chopped for garnish

Instructions
 

  • Preheat the oven to 375°F (190°C). Wash, peel, and thinly slice the potatoes. Place them in cold water to prevent browning and remove excess starch.
  • Melt butter over medium heat, sauté chopped onion until softened, then add minced garlic. Stir in flour to make a roux, cooking for 1-2 minutes.
  • Gradually whisk in milk and heavy cream, avoiding lumps. Simmer until thickened, then stir in cheeses, nutmeg, thyme, salt, and pepper until smooth.
  • Layer potatoes and cheese sauce in a greased 9×13 inch dish, ending with sauce. Cover with foil and bake at 375°F for 45 minutes.
  • Remove foil and bake for an additional 15-20 minutes, until golden brown. Let rest for 10-15 minutes before serving.

Notes

For the best flavor, use high-quality cheese and freshly ground spices. Letting the dish rest before serving helps the sauce set.
