Description

A comforting and savory French-inspired bake featuring layers of thinly sliced Yukon Gold potatoes and caramelized sweet onions, enriched with garlic, fresh thyme, and melted Gruyère cheese, all baked to golden perfection in a flavorful beef broth.


Ingredients

Scale

Potato and Onion Layers

  • 2 lbs Yukon Gold potatoes, thinly sliced
  • 3 large sweet onions, sliced
  • 2 cloves garlic, minced
  • 2 tsp fresh thyme, chopped
  • Salt and pepper to taste

Cooking Ingredients

  • 4 tbsp unsalted butter
  • 2 cups low-sodium beef broth
  • 1 ½ cups Gruyère cheese, shredded

Instructions

  1. Preheat and Prepare Dish: Preheat your oven to 375°F (190°C) and grease a baking dish thoroughly to prevent sticking and ensure even cooking.
  2. Sauté Onions: In a skillet over medium heat, melt the unsalted butter. Add the sliced onions and cook them slowly until they become golden brown and caramelized, which brings out their natural sweetness.
  3. Add Garlic and Thyme: Stir in the minced garlic and chopped fresh thyme into the onions and sauté for another minute or two until fragrant, enhancing the depth of flavor.
  4. Assemble Layers: In the prepared baking dish, layer half of the thinly sliced potatoes followed by half of the caramelized onion mixture. Repeat these layers with the remaining potatoes and onions for a rich, layered texture.
  5. Add Broth and Cheese: Pour the low-sodium beef broth evenly over the layered potatoes and onions to add moisture and savory notes. Then, sprinkle the shredded Gruyère cheese on top to create a creamy, cheesy crust.
  6. Bake Covered: Cover the baking dish with foil and bake in the preheated oven for 45 minutes, allowing the potatoes to cook through and flavors to meld.
  7. Bake Uncovered: Remove the foil and continue baking for an additional 15 minutes until the top is golden brown and bubbly.
  8. Rest and Serve: Allow the dish to rest for a few minutes after baking to set before serving. This ensures the layers hold together nicely and enhances the overall eating experience.

Notes

  • Use Yukon Gold potatoes for their creamy texture and ability to hold shape well.
  • Caramelizing the onions slowly is key to developing deep flavor – do not rush this step.
  • Covering with foil initially helps to cook the potatoes evenly and retain moisture.
  • Feel free to substitute beef broth with vegetable broth for a lighter version.
  • The dish pairs beautifully with a simple green salad or roasted vegetables.
