Ingredients

The key to this dish lies in selecting the right ingredients—fresh, simple, and full of flavor. I always choose firm, thinly sliced Yukon Gold potatoes because they hold their shape well and have a buttery texture. For the onions, sweet yellow or Vidalia varieties work beautifully when caramelized slowly. I also recommend using real butter and good-quality cheese; these little details make a big difference and bring out the comforting, homemade feel I love. If you want to lighten it up, you can swap half-and-half with whole milk, but I find the creaminess essential to that luscious texture.

  • 4 cups Yukon Gold potatoes, thinly sliced
  • 3 large yellow onions, thinly sliced
  • 3 tablespoons unsalted butter
  • 1 cup shredded Gruyère cheese (or Swiss cheese as a substitute)
  • 1 cup half-and-half cream
  • 2 cloves garlic, minced
  • 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
  • Salt and freshly ground black pepper, to taste
  • 1 tablespoon all-purpose flour (optional, for thickening)

Instructions

  1. Preheat your oven to 375°F (190°C). Butter a medium baking dish to prevent sticking and add richness.
  2. In a large skillet, melt the butter over medium-low heat. Add the sliced onions and a pinch of salt. Cook slowly, stirring occasionally, until onions are deeply golden and caramelized, about 30-40 minutes. This slow caramelization is key to the dish’s rich flavor.
  3. Once the onions are ready, stir in the minced garlic and thyme. Cook for an additional 1-2 minutes until fragrant.
  4. Sprinkle the flour over the onions, if using, and stir well. This will help thicken the liquid for a creamier bake.
  5. Pour in the half-and-half, stirring constantly, and let the mixture simmer gently for 3-4 minutes until slightly thickened. Season with salt and pepper to taste.
  6. Layer half of the sliced potatoes evenly in the baking dish. Pour half of the onion mixture over the potatoes, then sprinkle with half the cheese. Repeat with remaining potatoes, onions, and cheese layers.
  7. Cover the dish with foil and bake for 40 minutes. Then remove the foil and bake for another 15-20 minutes, or until the potatoes are tender and the cheese is golden and bubbly.
  8. Let the bake rest for 5-10 minutes before serving. This helps it set and makes it easier to serve.
