Ingredients

• 2 lb Yukon Gold potatoes
• 4 tbsp Unsalted butter
• 2 tbsp Olive oil
• 2 large Yellow onions
• 3 clove Garlic cloves
• 1 tsp Dried thyme
• 1 cup Beef or vegetable broth
• 0.25 cup Heavy cream
• 1 cup Shredded Gruyère cheese
• 1 tsp Salt
• 0.5 tsp Black pepper
• 2 tbsp Chopped fresh parsley (optional for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Wash and peel the Yukon Gold potatoes. Slice them into thin rounds, about 1/4 inch thick. Set aside.

Step 3

Peel the yellow onions and slice them thinly into half-moons. Mince the garlic cloves.

Step 4

In a large skillet over medium heat, melt 2 tablespoons of butter with 1 tablespoon of olive oil. Add the sliced onions and a pinch of salt. Cook for 20-25 minutes, stirring occasionally, until the onions are soft and caramelized. If they start to stick, add a splash of water to deglaze the pan.

Step 5

Add the minced garlic and dried thyme to the skillet. Cook for an additional 1-2 minutes, until fragrant. Remove from heat and set aside.

Step 6

In a small saucepan, combine the broth and heavy cream. Heat over low heat until warmed through, but do not let it boil. Season with salt and black pepper.

Step 7

Grease a 9x13-inch baking dish with the remaining tablespoon of olive oil. Layer half of the sliced potatoes in the dish, slightly overlapping them.

Step 8

Spread half of the caramelized onions over the potato layer. Pour half of the broth and cream mixture over the onions. Sprinkle half of the shredded Gruyère cheese over the top.

Step 9

Repeat the layering process with the remaining potatoes, onions, broth mixture, and cheese.

Step 10

Dot the top with the remaining 2 tablespoons of butter, cut into small pieces.

Step 11

Cover the baking dish tightly with aluminum foil and bake for 30 minutes.

Step 12

After 30 minutes, remove the foil and bake for an additional 20-25 minutes, until the potatoes are tender and the top is golden brown and bubbling.

Step 13

Let the dish rest for 5 minutes before serving. Garnish with fresh chopped parsley, if desired.
