- Yield:Serves 2
- Active time: 40 minutes
- Total time:40 minutes
- About 2 tablespoons plus 1 teaspoon vegetable oil
- 1/4 pound pancetta, chopped (about 3/4 cup)
- 2 large shallots, finely chopped (about 3/4 cup)
- 1 1/2 pounds (about 3) Yukon gold potatoes
- Kosher salt and freshly ground black pepper
- 2 teaspoons picked thyme leaves
- 1/2 cup sour cream
Heat 1 teaspoon of vegetable oil in a 10- inch non stick skillet over medium high heat until shimmering. Add chopped pancetta and cook, stirring until pancetta is crisp, about 5 minutes. Add chopped shallots and cook, stirring frequently, until soft and translucent, about 5 minutes. Transfer shallots and pancetta to a large bowl using a slotted spoon. Transfer fat to a cup. Add enough oil to add up to about 4 tablespoons total fate. Set skillet aside.
Using the largest holes on a box grater grate potatoes one at a time. Place grated potato in the center of a clean tea towel and twist tea towel to drain out liquid over sink. Transfer to bowl with pancetta and shallots. Season to taste with salt and pepper. Add 1 1/2 teaspoons picked thyme leaves and toss to combine.
Wipe out skillet. Heat 1 tablespoon of fat over medium heat, and when shimmering add 1/2 of potato mixture to the skillet. Using a rubber spatula, press into the bottom of the pan and cook until edges begin to look brown, about 6 minutes. Carefully slide roesti onto a plate then place another plate on top. Flip plates over, then slide roesti back into pan and continue to cook until completely crisp, about 7 minutes longer. Transfer to a large plate and keep warm in a 200°F oven. Repeat with remaining fat and potato. Sprinkle roesti with thyme and serve with sour cream.
