Recipe Description
This dish has roots in French cuisine, where "au gratin" refers to a technique where a dish is topped with breadcrumbs, cheese, and butter, then baked or broiled until crispy and golden. In this version, thinly sliced Yukon Gold potatoes are layered with a creamy blend of heavy cream, roasted garlic, and a mix of Parmesan and Gruyere cheeses, then baked to golden perfection. For a twist, try adding other cheeses like sharp cheddar or fontina. This gratin pairs beautifully with roasted chicken, seared steak, or baked ham.

ingredients
- 1 1/2 cups heavy cream
- 2 teaspoons kosher salt
- 1 head of roasted garlic
- 1 tablespoon unsalted butter
- 1 shallot, diced
- 5 medium Yukon Gold or white potatoes
- 1 cup freshly grated Gruyere
- 1/2 cup freshly grated Parmesan
- Fresh thyme, for topping
Method
Step 1
Preheat the oven to 400°F.
Step 2
Use a mandoline slicer to slice the potatoes into 1/8 inch thick.
Step 3
Melt the butter over low heat in a large cast iron pan, then add the diced shallots. Cook for about 5 minutes until the shallots caramelize. Squeeze the roasted garlic head into the pan and mix with the shallots.
Step 4
In a bowl, combine the caramelized onion, garlic, grated cheese, heavy cream, salt, and pepper. Set aside 1/4 of this mixture for later use.
Step 5
Toss the sliced potatoes with the cheese mixture until evenly coated.
Step 6
Arrange the sliced potatoes in a spiral pattern in the cast iron pan. Pour the reserved cheese mixture over the top and sprinkle with fresh thyme leaves.
Step 7
Cover the cast iron pan tightly with aluminum foil and bake in the preheated oven for 1 hour.
Step 8
Remove the foil and switch the oven to broil. Optionally, sprinkle additional Parmesan and Gruyere on top for an extra crispy layer. Broil for 5 minutes.
Step 9
Once done, remove from the oven and serve warm.
Step 10
Leftovers can be stored in the fridge and reheated the next day.
