Ingredients

  • 3 lbs Yukon Gold potatoes best texture + flavor
  • 3 tbsp butter
  • 3 cloves garlic minced
  • 3 tbsp all-purpose flour
  • 2 cups whole milk
  • 1 cup heavy cream
  • 1 1/2 tsp kosher salt
  • 1/2 tsp black pepper
  • 1/2 tsp smoked paprika or regular paprika
  • 1 tsp fresh thyme or ½ tsp dried
  • 2 cups freshly grated sharp cheddar (
  • 1 cup freshly grated Gruyère
  • Optional: ½ cup Parmesan for topping

Instructions

  • Step 1: Prep
  • Heat oven to 375°F
  • Butter a 9×13 baking dish
  • Slice potatoes 1/8-inch thin (a mandoline makes this easier)
  • Step 2: Make the Cheese Sauce
  • Melt butter in a saucepan over medium heat
  • Add garlic and cook about 30 seconds
  • Whisk in flour and cook for 1 minute
  • Slowly whisk in milk and cream
  • Simmer until thick enough to coat a spoon (about 3–4 minutes)
  • Stir in salt, pepper, paprika, and thyme
  • Remove from heat and stir in cheddar and Gruyère until smooth
  • This sauce is the heart of the recipe — creamy, cheesy, and full of flavor.
  • Step 3: Assemble
  • Layer half the potatoes in the dish
  • Pour over half the sauce and gently press down
  • Repeat with remaining potatoes and sauce
  • Sprinkle Parmesan on top if using
  • Step 4: Bake
  • Cover tightly with foil and bake 45 minutes
  • Uncover and bake 25–30 more minutes until golden and bubbly
  • Let rest 10–15 minutes before serving (this helps it set!)
