ingredients
- 3 lbs Yukon Gold potatoes, peeled and thinly sliced (about 1/8 inch)
- 5 large yellow onions, thinly sliced
- 3 tbsp unsalted butter
- 1 tbsp olive oil
- 2 cloves garlic, minced
- 1 tsp fresh thyme leaves
- 1/2 cup dry white wine
- 2 cups beef or vegetable broth
- 1 1/2 cups Gruyère cheese, grated
- 1 cup Emmental cheese, grated
- 1/2 cup Parmesan cheese, grated
- Salt and freshly ground black pepper, to taste
- 1 tbsp all-purpose flour (optional, to thicken)
Instructions
- Caramelize the onions: Heat butter and olive oil in a large skillet over medium heat. Add sliced onions and a pinch of salt. Cook slowly, stirring occasionally to avoid burning, until rich amber and soft, about 40-45 minutes.Add minced garlic and thyme during the last 5 minutes.For deeper flavor, deglaze pan with white wine, scraping browned bits from the bottom.
- Prepare the potatoes: While onions caramelize, peel and slice Yukon Gold potatoes thinly for even cooking and a creamy texture that holds shape.
- Layer the bake: Preheat oven to 375°F (190°C). Butter a 9×13-inch baking dish.Spread a thin layer of caramelized onions on the bottom. Arrange a layer of potatoes over the onions, seasoning lightly with salt and pepper. Sprinkle a mixture of Gruyère and Emmental cheese, then repeat layering potatoes, onions, seasoning, and cheese until ingredients are used, finishing with a generous sprinkle of Parmesan on top.
- Add broth and thicken: if desired, whisk the flour into the broth to create a slightly thickened base and pour slowly over the layered potatoes. This helps the dish meld together with creamy sauce-like consistency during baking.
- Bake to golden perfection: Cover the dish tightly with foil to trap steam and bake for 50 minutes. Remove foil, increase oven temp to 425°F (220°C), and bake an additional 15 minutes uncovered to develop a golden, bubbling crust. Watch closely to avoid burning.
- Rest and serve: Let the dish rest for 10 minutes before slicing to allow the flavors to settle and layers to firm slightly for clean serving.
Tips for Success
- Potatoes: Yukon Golds provide creamy texture and maintain structure, but thinly sliced Russets can be used for a fluffier interior.
- Cheese blend: gruyère offers nuttiness and meltability; Emmental adds elasticity, and Parmesan crisps the top beautifully. Experiment with Comté for an authentic French twist.
- Caramelization: Patience is key; rushing onions leads to bitterness rather than depth. Low heat and consistent stirring are your best friends.
- Make ahead: assemble the bake but hold the final bake step covered in the fridge up to 24 hours. Bake fresh before serving.
- Broth choices: Use a rich beef broth for traditional depth, or vegetable broth for a lighter vegetarian-friendly option.
Serving Suggestions
