- Level: Easy
- Total: 35 min
- Active: 35 min
- Yield: 4 servings
Ingredients
4 large Yukon gold potatoes
Kosher salt and freshly ground black pepper
4 tablespoons canola oil
6 tablespoons unsalted butter
2 large yellow onions, halved and thinly sliced
Pinch of sugar
4 teaspoons white wine vinegar
1/4 cup chopped fresh flat-leaf parsley
2 sprigs fresh thyme, leaves removed, plus more for garnish
Directions
- Put the potatoes in a large pot and cover by 2 inches with cold water. Add 1 tablespoon of kosher salt and bring to a boil over high heat. Cook until a knife inserted into the center meets some resistance, 15 minutes. Drain and let cool slightly.
- While the potatoes are cooking, heat 2 tablespoons of the oil in a large saute pan over medium heat. Add 2 tablespoons of the butter, the onions, sugar and some salt and pepper. Cook, stirring occasionally, until the onions are soft and caramelized. Remove to a platter.
- Slice the potatoes in half lengthwise, then crosswise into 1/2-inch-thick half-moon-shaped slices. Sprinkle both sides of the potato slices with salt and pepper.
- Heat the remaining 2 tablespoons oil in the same saute pan over medium-high heat. Add the potatoes in a single layer, then add 2 tablespoons of butter and cook on both sides (being careful not to break the slices) until lightly golden brown and crisp around the edges, about 7 minutes. Stir in the onions, remaining 2 tablespoons butter and the white wine vinegar. Finish with the parsley and thyme.
- Serve hot, garnished with thyme sprigs.
