Ingredients

Scale

Potatoes and Vegetables

  • 2 lbs Yukon Gold potatoes, thinly sliced
  • 3 large sweet onions, sliced
  • 2 cloves garlic, minced

Dairy and Cheese

  • 4 tbsp unsalted butter
  • 1 ½ cups Gruyère cheese, shredded

Liquids and Seasonings

  • 2 cups low-sodium beef broth
  • 2 tsp fresh thyme, chopped
  • Salt and pepper to taste

Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C) and grease a baking dish thoroughly to prevent sticking and ensure easy serving.
  2. Sauté Onions: In a skillet over medium heat, melt the unsalted butter. Add the sliced sweet onions and cook them slowly until they become golden brown and caramelized, which develops their rich flavor.
  3. Add Garlic and Thyme: Stir in the minced garlic and chopped fresh thyme into the skillet with the onions. Cook for another minute or two until the garlic is fragrant and the herbs blend into the onions.
  4. Layer Ingredients: In your greased baking dish, layer half of the thinly sliced potatoes, then spread half of the caramelized onion mixture on top. Repeat with the remaining potatoes and onion mixture to create two layers.
  5. Add Broth and Cheese: Pour the low-sodium beef broth evenly over the layered potatoes and onions. Finally, sprinkle the shredded Gruyère cheese over the top layer for a creamy, cheesy crust.
  6. Bake Covered: Cover the baking dish tightly with foil and bake in the preheated oven for 45 minutes to allow the potatoes to cook through and absorb the savory flavors.
  7. Bake Uncovered: Remove the foil and continue baking for an additional 15 minutes. This step browns the cheese topping to a beautiful golden brown and adds a slight crispiness.
  8. Rest and Serve: Let the potato bake rest for a few minutes after removing from the oven to set and make slicing easier. Serve warm as a hearty side or a comforting main dish.

Notes

  • Thinly slice the potatoes evenly to ensure consistent cooking.
  • Using low-sodium beef broth helps control the saltiness of the dish.
  • Gruyère can be substituted with Emmental or Swiss cheese for a similar flavor.
  • Allow the dish to rest before cutting to keep slices intact.
  • For a vegetarian version, replace beef broth with vegetable broth.
