2 lb (900 g) small Yukon Gold potatoes 1 tbsp kosher salt, plus more to taste 1 / 2 tsp baking soda 3 tbsp olive oil, divided Freshly ground black pepper, to taste 1 bunch scallions 1 tsp Dijon mustard 1 tsp honey 1 tsp finely grated lemon zest 2 tbsp fresh lemon juice 1 tbsp red wine vinegar 1 / 4 tsp red pepper flakes (or Aleppo pepper) 1 / 4 cup (60 ml) extra-virgin olive oil 2 tbsp chopped fresh chives (optional)
Heat oven to 450°F (230°C). Place a rimmed baking sheet on the middle rack to preheat. Place potatoes in a pot, cover with cold water by 1 inch, add 1 tablespoon kosher salt and the baking soda. Bring to a boil and simmer until tender when pierced, 12–15 minutes. Drain and let steam dry 5 minutes. Carefully remove the hot baking sheet, add 2 tablespoons olive oil, and tilt to coat. Arrange potatoes on the sheet and gently smash each to about 1/2 inch thick. Drizzle with the remaining 1 tablespoon olive oil; season with salt and black pepper. Roast 20 minutes, then flip and roast 15–20 minutes more until deeply crisp and golden. While potatoes roast, toss scallions with a light drizzle of oil. Add to the baking sheet for the last 8–10 minutes, turning once, until charred and tender. Cool slightly, then finely chop. Make the vinaigrette: In a bowl, whisk Dijon, honey, lemon zest, lemon juice, red wine vinegar, red pepper flakes, and a pinch of salt. Slowly whisk in the extra-virgin olive oil until emulsified. Stir in the chopped charred scallions. Transfer hot potatoes to a bowl, drizzle with most of the vinaigrette, and toss to coat. Taste and adjust salt and pepper. Scatter with chives (if using) and serve warm with extra vinaigrette alongside.
