Ingredients
Scale
Roasted Garlic Cream
- 1 head garlic
- ⅓ cup whole milk
- 1 ¼ cups heavy cream
- 1 heavy pinch salt
- 1 tsp white pepper
- ½ tsp allspice
- ½ tsp smoked paprika
- 1 tsp herbs de Provence
Potatoes and Cheese
- 2.5 lbs Yukon Gold potatoes
- Butter, for greasing
- 8 oz Gruyere cheese
- 6 oz Parmigiano Reggiano cheese
Toppings
- Crème fraîche, for topping
- Chives, chopped, for topping
- Caviar, to taste (optional)
Instructions
- Roast the garlic: Preheat the oven to 375°F. Slice the top off the garlic head, drizzle lightly with olive oil, wrap in foil, and roast for 1 hour until the garlic cloves are soft and golden. Let it cool, then reduce the oven temperature to 350°F.
- Make the garlic cream: Squeeze the cooled roasted garlic cloves into a blender with the milk and blend until smooth. Pour into a saucepan, add heavy cream, salt, white pepper, allspice, smoked paprika, and herbs de Provence. Warm gently over low heat until steamy without boiling. Set aside.
- Prep the potatoes: Using a mandoline, slice the Yukon Gold potatoes very thinly to ensure even layers and cooking.
- Prepare the baking dish: Butter an 8×8-inch baking dish and line it with two overlapping sheets of parchment paper, leaving overhang on the sides to lift the gratin later.
- Combine the cheese: Mix together the Gruyere and Parmigiano cheeses. Reserve half of the mixture in the refrigerator for topping later; use the other half for layering.
- Layer the potatoes: Pour a thin ladleful of garlic cream on the bottom of the pan. Build layers in this order: thin layer of potatoes, garlic cream, potatoes, garlic cream, a very thin layer of cheese mix, potatoes. Repeat until you have 8 potato layers, finishing with potatoes topped by garlic cream.
- Bake to set: Cover the dish tightly with foil and bake at 350°F for 75 minutes to cook the potatoes through and let the flavors meld.
- Press and chill: Allow the gratin to cool. Place a parchment sheet on top, then invert another 8×8-inch baking dish on top and press down firmly. Add heavy cans or weights to compress the layers. Refrigerate for at least 8 hours or overnight to set the stacks.
- Chill and prep to bake: After chilling, transfer the gratin to the freezer for about 30 minutes while preheating the oven to 425°F. This firms the stacks for clean cutting.
- Cut into stacks: Use the parchment overhang to lift the gratin slab out of the pan. Trim the edges neatly and cut into square or rectangular stacks.
- Top with cheese and bake: Arrange the stacks on a parchment-lined baking sheet. Evenly top each stack with the reserved Gruyere and Parmigiano mixture. Bake for 35–45 minutes at 425°F until the cheese is deeply golden and bubbly.
- Top and serve: Garnish the gratin stacks with fresh chopped chives, a dollop of crème fraîche, and optional caviar for a luxurious finish. Serve warm and enjoy!
Notes
- Use a mandoline for uniform potato slices to ensure even cooking and layering.
- Roasted garlic adds a milder, sweeter garlic flavor compared to raw garlic.
- Pressing and chilling the gratin helps the stacks hold their shape when cut.
- For extra richness, use full-fat dairy products as specified.
- Optional caviar adds an elegant touch but can be omitted for a simpler dish.
- Leftover stacks can be refrigerated and reheated gently before serving.
