Ingredients
  

For the Potatoes au Gratin
  • 2 lb russet potatoes peeled and thinly sliced
  • 1 cup heavy cream
  • 1 cup whole milk
  • 3 cups shredded Gruyère cheese
  • 2 cups shredded sharp cheddar cheese
  • 4 tbsp unsalted butter
  • 2 cloves garlic minced
  • 1 tsp salt
  • 0.5 tsp black pepper
  • 0.5 tsp paprika
  • 0.25 tsp nutmeg
  • Fresh parsley, chopped

Equipment

  • Sharp Knife
  • Cutting Board
  • Large saucepan
  • Baking dish
  • Mixing spoon
  • Aluminum foil
  • Measuring Cups and Spoons

Method
 

  1. Step 1: Preheat your oven to 375°F (190°C).
  2. Step 2: In a large saucepan over medium heat, melt the butter. Once melted, add the minced garlic and sauté for about 1 minute until fragrant.
  3. Step 3: Stir in heavy cream and whole milk, increase the heat slightly and bring the mixture to a simmer. Then add salt, black pepper, paprika, and nutmeg.
  4. Step 4: Gradually add shredded Gruyère and cheddar cheese, stirring constantly until the cheese is melted and the sauce is smooth.
  5. Step 5: In a greased baking dish, layer half of the sliced potatoes evenly across the bottom. Pour half of the cheese sauce over the first layer of potatoes.
  6. Step 6: Add the remaining potatoes on top, followed by the rest of the cheese sauce. Cover the dish with aluminum foil and bake for 45 minutes.
  7. Step 7: After 45 minutes, remove the foil and bake for an additional 15-20 minutes, until the top is golden and bubbly.
  8. Step 8: Allow to cool slightly before garnishing with fresh chopped parsley.

Notes

Leftover potatoes can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven to retain that creamy texture.
