Ingredients
- 2 tbsp olive oil
- 1 medium yellow onion, peeled and finely sliced
- 3 cloves garlic, minced
- 2 cups heavy cream
- 1 tbsp fresh thyme leaves (or rosemary), chopped
- 1 tbsp dijon mustard
- 1 tsp kosher salt,
- 1/3 tsp freshly ground black pepper
- 3 pounds Yukon gold potatoes, scrubbed and cut into 1/8 inch thick slices
- 2 cups Gruyère cheese, shredded
- 1/2 cup grated parmesan cheese
- 1 tbsp fresh chives, thinly sliced
Instructions
- Preheat the oven to 450 F and lightly grease a baking sheet with olive oil to prevent sticking.
- In a small saucepan over a medium heat, add the olive oil. When hot, add the onion. Cook, stirring occasionally, for 3 minutes, or until it begins to soften, then add the garlic and continue cooking for one more minute. Mix in the heavy cream, herbs, dijon, salt, and pepper. Reduce the heat and simmer for about 2 minutes before removing from the heat.
- While the onions cook, scrub, dry and slice the potatoes into 1/8-inch slices. (a mandonline is helpful) Pat the potato slices dry with paper towels and add them to a large mixing bowl. Season the potatoes with a good pinch of salt and pepper. Lay 1/2 of the potatoes on the prepared baking sheet. The rows of potatoes should only just touch and the potatoes should fill the pan. Sprinkle the Gruyere cheese mix over the potatoes and top with the parmesan cheese.
- Top with the remaining potato slices and pour the heavy cream mixture evenly over the potatoes. Use a spatula to make sure the mixture is evenly spread. Sprinkle the remaining Gruyere mix and parmesan over top and bake, covered with foil, for 40 minutes.
- Remove the foil and continue cooking, uncovered, for 15-20 minutes until the cheese is golden brown and bubbly. When finished, remove the potatoes from the oven and allow them to cool for a few minutes before garnishing with chives and serving.
