Ingredients
Scale
Potatoes & Onions
- 2 pounds Yukon Gold potatoes, peeled and thinly sliced
- 3 large yellow onions, thinly sliced
Cheese & Dairy
- 1 ½ cups shredded Gruyere cheese
- 1 cup milk or cream
Flavorings & Seasonings
- 3 tablespoons butter
- 3 cloves garlic, minced
- 1 teaspoon fresh or dried thyme
- Salt, to taste
- Black pepper, to taste
Instructions
- Caramelize the Onions: Slice the yellow onions thinly. Melt 3 tablespoons of butter in a large skillet over medium-low heat. Add the onions and cook them slowly, stirring frequently, until they turn golden brown and develop a deep, sweet flavor. This process takes about 30 minutes—patience is key for maximum flavor.
- Prepare the Potatoes: While the onions caramelize, peel and thinly slice the Yukon Gold potatoes to ensure even cooking and tender texture once baked.
- Assemble the Bake: Lightly grease your baking dish. Layer half of the sliced potatoes evenly at the bottom. Spread the caramelized onions over the potatoes. Sprinkle minced garlic, thyme, salt, and black pepper to taste over the onions. Then add the remaining potato slices on top.
- Add Cheese and Cream: Pour 1 cup of milk or cream evenly over the layered potatoes and onions. Generously scatter the 1 ½ cups of shredded Gruyere cheese across the surface to melt and turn golden during baking.
- Bake to Perfection: Cover the baking dish with foil. Bake at 375°F (190°C) for 40 minutes. Remove the foil and continue baking for another 20 minutes or until the cheese is bubbly and golden and the potatoes are fork-tender.
Notes
- Use thin potato slices to ensure even baking and a tender, creamy texture.
- Slowly caramelize onions without rushing to develop deep, sweet flavor.
- Let the bake rest for 10 minutes after baking for cleaner slices and easier serving.
- Choose melting cheeses like Gruyere or fontina for best gooey texture.
- Season each layer lightly with salt and pepper to balance flavors throughout.
