Prep Time: 20 minutes
Cook Time: 1 hour
Total Time: 1 hour 20 minutes


  • 2 1⁄2 pounds Russet or Yukon Gold potatoes, peeled and sliced paper-thin
  • 1 cup heavy cream
  • 1 cup whole milk
  • 3 tablespoons unsalted butter
  • 2 garlic cloves, minced
  • 1 teaspoon salt
  • 1⁄2 teaspoon black pepper
  • 1 cup grated Parmesan cheese
  • 1⁄2 cup breadcrumbs
  • Fresh parsley, chopped (for garnish)


  1. Preheat oven to 350°F. The oven should be fully preheated before baking.
  2. Slice potatoes into translucently thin rounds using a mandoline slicer or a very sharp knife. Aim for a thickness of about 1/8 inch. Thinner slices will cook faster and more evenly. Rinse the slices in cold water to remove excess starch. Pat thoroughly dry with paper towels or a clean dishcloth before assembling.
  3. Make velvety sauce:
  4. In a medium saucepan, melt 2 tablespoons of unsalted butter over medium heat. Once melted, add minced garlic and cook for 1 minute until fragrant. Be careful not to burn the garlic.
  5. Sprinkle the flour over the melted butter and whisk vigorously to form a smooth roux. Continue cooking the roux for 2 minutes, whisking constantly to avoid any lumps.
  6. Gradually whisk in the milk and heavy cream until fully incorporated. Season with salt, freshly cracked black pepper, and a pinch of freshly grated nutmeg.
  7. Bring the sauce to a gentle simmer, whisking frequently. Cook for 5-7 minutes, until the sauce thickens to a velvety, coat-the-back-of-spoon consistency. Remove from heat.
  8. Assemble layered masterpiece in a buttered baking dish:
  9. Use 1 tablespoon of butter to generously grease a 2-quart shallow baking dish. This allows for a large surface area for crispy, cheesy topping.
  10. Arrange a single, even layer of potato slices over the bottom of the dish. Season with a pinch of salt and pepper.
  11. Ladle 1/3 of the hot sauce evenly over the potato layer. Spread to completely coat each slice.
  12. Sprinkle 1/3 of the grated Parmesan cheese over the sauced potatoes.
  13. Build another layer of potato slices and repeat the process, using half the remaining sauce and cheese.
  14. Top with a final layer of potatoes, the last of the sauce, and a generous sprinkling of Parmesan and breadcrumbs.
  15. Bake uncovered for 60-75 minutes, until potatoes are fork-tender and the top is bubbling and golden brown. If topping browns too quickly, loosely tent foil over the dish.
  16. Let the dish rest for 10 minutes before serving. This allows the sauce to thicken and lets the layers settle, ensuring clean, elegant slices.
  17. Garnish with chopped fresh parsley. The green brightens the creamy dish. Serve warm.

Cooking Tips:

  • Use a mandoline for uniform potato slices
  • Keep roux on the thinner side to avoid a gluey sauce
  • Shallow dish ensures even browning and crisp top
  • Test doneness by easily inserting a knife through potatoes
  • Resting allows sauce to settle for clean, elegant plating
