A comforting dish featuring tender potatoes layered with caramelized onions, melted cheese, and a rich, creamy sauce, perfect for weeknights or special gatherings.
Ingredients
Main Ingredients
- 4 large potatoes, thinly sliced
- 2 large onions, thinly sliced Vidalia or yellow onions work beautifully
- 2 tablespoons butter
- 2 cups shredded cheese Gruyère or mozzarella recommended
- 1 cup heavy cream Substitute with half-and-half or whole milk for a lighter version
- Salt and pepper to taste
- Fresh thyme for garnish Optional but recommended
Instructions
Preparation
- Preheat your oven to 375°F (190°C).
- In a large skillet, melt the butter over medium heat. Add your sliced onions and let them cook slowly until they’re beautifully caramelized, which should take about 15-20 minutes.
- In a greased baking dish, layer half of the sliced potatoes, followed by half of the caramelized onions, and then half of the cheese. Repeat this layering until everything is nicely stacked.
- Pour the heavy cream over the top layer and sprinkle with salt and pepper for seasoning.
- Cover the dish with aluminum foil and pop it into the oven to bake for 45 minutes.
- After 45 minutes, remove the foil, sprinkle the remaining cheese on top, and bake for an additional 15 minutes or until the top is golden and bubbly.
- If you want to elevate the presentation, garnish with fresh thyme before serving warm.
