Ingredients
Scale
- 1 1/2 cups heavy cream
- 2 tsp kosher salt
- 3 cloves garlic, minced
- 1 tbsp butter
- 1 small shallot, diced
- 5 medium Yukon Gold or White potatoes
- 1 cup grated Gruyere cheese
- 1/2 cup grated Parmesan cheese
- 1 tsp fresh thyme
Instructions
-
Preheat the Oven:
- Set oven to 325°F (163°C).
-
Infuse the Cream:
- In a small saucepan, combine heavy cream, salt, and garlic.
- Simmer over low heat for 5 minutes to allow the garlic to infuse the cream.
- Remove from heat and set aside.
-
Prepare the Potatoes:
- Using a mandoline slicer, thinly slice the potatoes to ⅛-inch thickness.
-
Sauté the Shallots:
- In a 12-inch cast iron pan, melt butter over low heat.
- Add shallots and sauté until caramelized, about 5 minutes.
-
Layer the Potatoes:
- Arrange sliced potatoes in a spiral pattern over the caramelized shallots in the pan.
-
Add the Cream:
- Pour the infused cream mixture evenly over the potatoes.
-
Bake the Gratin:
- Cover the pan tightly with aluminum foil.
- Bake for 1 hour and 15 minutes.
-
Broil the Cheese:
- Remove the pan from the oven and increase temperature to broil.
- Uncover the potatoes and top with Gruyere and Parmesan cheese.
- Sprinkle with fresh thyme.
-
Finish Under the Broiler:
- Return the pan to the oven and broil for 5 minutes, or until the cheese is crispy and bubbling.
-
Serve and Store:
- Remove from the oven and serve warm.
- Store leftovers in the refrigerator and reheat the next day.
Notes
- Yukon Gold potatoes work best for a creamy texture, but Russet potatoes can be used for a more structured gratin.
- For an extra crispy top, broil for an additional 2 minutes, but watch closely to prevent burning.
- Pairs beautifully with roast chicken, steak, or a holiday feast!
