Ingredients

Scale
  • 4 medium russet potatoes, thinly sliced (about 1/8 inch thick)
  • 3 tablespoons olive oil (or vegetable oil)
  • Salt, to taste
  • Freshly ground black pepper, to taste
  • Cheese Sauce Ingredients:
  • 2 tablespoons unsalted butter
  • 2 tablespoons all-purpose flour (use gluten-free flour for GF version)
  • 1 cup whole milk, warmed (or dairy-free milk like almond milk)
  • 1 ½ cups sharp cheddar cheese, shredded
  • 1 teaspoon Dijon mustard
  • 1 small garlic clove, minced
  • Salt and pepper, to taste
  • Optional Toppings:
  • 2 green onions, thinly sliced
  • 3 strips cooked bacon, crumbled
  • Sour cream or Greek yogurt, for dolloping
  • Fresh chopped parsley or chives

Instructions

  1. Wash and peel potatoes if desired. Slice into very thin rounds about 1/8 inch (3 mm) thick using a mandoline slicer or sharp knife.
  2. Place sliced potatoes in cold water and swish to remove excess starch. Drain and pat thoroughly dry with paper towels.
  3. Heat olive oil in a large skillet over medium-high heat. Fry potato slices in a single layer without overcrowding for 3-4 minutes per side until golden and crisp. Work in batches and drain on paper towels.
  4. In a medium saucepan, melt butter over medium heat. Whisk in flour and cook for 1-2 minutes to form a roux.
  5. Slowly whisk in warmed milk, stirring constantly until sauce thickens, about 5 minutes.
  6. Remove from heat and stir in shredded cheddar, Dijon mustard, minced garlic, salt, and pepper.
  7. On a large serving platter or oven-safe dish, layer the crispy potato slices. Pour cheese sauce evenly over the top.
  8. Sprinkle with green onions, crumbled bacon, and fresh herbs. Optionally, broil for 1-2 minutes to bubble the cheese sauce, watching carefully to avoid burning.
  9. Serve immediately with dollops of sour cream or Greek yogurt while warm.
