Ingredients

Scale

Vegetables

  • 2 lbs yellow potatoes, washed, peeled, and thinly sliced
  • 2 large sweet onions, thinly sliced
  • 2 cloves garlic, minced
  • Fresh thyme or other fresh herbs, to taste
  • Salt and pepper, to taste

Dairy and Fats

  • 3 tablespoons unsalted butter (plus extra for greasing the dish)
  • 1 cup whole milk
  • 1 cup heavy cream
  • 1 1/2 cups grated Gruyère or sharp cheddar cheese

Dry Ingredients

  • 3 tablespoons all-purpose flour (or gluten-free alternative like cornstarch or rice flour)

Instructions

  1. Caramelize the Onions: Thinly slice the sweet onions and sauté them gently in 2 tablespoons of butter over low heat for 25-30 minutes, stirring often, until golden brown and sweetly caramelized.
  2. Prepare the Cheese Sauce: In a separate saucepan, melt 1 tablespoon butter and whisk in the flour to form a roux. Gradually add the milk and cream while stirring continuously. Cook until the sauce thickens to a smooth, creamy consistency. Stir in the grated cheese, minced garlic, fresh thyme, salt, and pepper to develop the classic French onion flavor.
  3. Slice the Potatoes: Wash, peel, and slice the yellow potatoes into even thin rounds to ensure uniform cooking and a tender texture.
  4. Layer the Dish: Butter a baking dish. Alternate layers starting with a layer of potato slices, then caramelized onions, followed by cheese sauce. Lightly season each layer with salt and pepper. Repeat until all ingredients are used, finishing with a generous layer of cheese on top.
  5. Bake to Perfection: Cover the dish with foil and bake in a preheated oven at 350°F (175°C) for 45 minutes. Remove the foil and bake for an additional 15 minutes until the top is golden brown and edges are slightly crispy. Let rest for a few minutes before serving to allow layers to set.

Notes

  • Use a mandoline slicer for uniformly thin potato slices.
  • Slow caramelization of onions is essential for deep sweetness and flavor.
  • Do not rush baking; low and slow cooking ensures tender potatoes and well-melded flavors.
  • Let the dish rest after baking to thicken the sauce and improve slicing.
  • Garnish with fresh herbs like thyme or parsley for fresh contrast.
  • To make gluten-free, substitute flour with cornstarch or rice flour.
  • For a vegan version, use plant-based butter, dairy-free milk (almond or oat), and vegan cheese.
