Gruyere Potato Gratin
Servings 8
Ingredients
- 1 1/2 cups heavy cream
- 2 tsp kosher salt
- 3 cloves garlic minced
- 1 tbsp butter
- 1 shallot diced
- 5 Yukon Gold potatoes medium
- 1 cup Gruyere grated
- 1 /2 cup Parmesan grated
- 1 tsp thyme
Instructions
- Preheat the oven to 325 F.
- In a small saucepan add the cream, salt, and garlic. Bring to a simmer on low heat a cook for 5 minutes. This will allow the garlic flavor to infuse the cream. Remove from the heat and set to the side.
- Thinly slice the potatoes to 1/8 inch thickness using a mandoline slicer.
- In a 12 inch cast iron pan, add the butter and shallots and fry on low heat for 5 minutes until the shallots have caramelized.
- Arrange the sliced potatoes in a spiral pattern on top of the cooked shallots. Pour the cream mixture over top of the potatoes.
- Cover the cast iron pan tightly with a piece of tin foil. Place the cast iron pan into the oven and bake for 1 hr and 15 minutes.
- Remove the pan from the oven and turn the oven temperature to broil.
- Cover the potatoes with the grated Gruyere and Parmesan cheeses. Sprinkle with the thyme. Place the cast iron pan into the oven and broil for 5 minutes until the cheese is crispy and bubbling.
- Remove from the oven and serve warm.
- Store and reheat for the following day if needed.
