- 2 lb. baby potatoes (Red, White, or Yukon Gold)
- 1 tbsp. kosher salt, plus additional for sprinkling
- 2 tbsp. unsalted butter, melted
- 2 tbsp. olive oil
- 2 tbsp. white vinegar
- Freshly ground black pepper
- Preheat oven to 450° F. Line a large baking sheet with parchment paper, set aside.
- Add potatoes and 1 tbsp. kosher salt to a medium saucepan. Cover with water and bring to a boil. Reduce heat and simmer until potatoes are tender, about 20 minutes.
- Drain and return potatoes to saucepan. Add butter and gently toss to coat. Transfer potatoes to prepared baking sheet, spreading them out in a singer layer. Using a heavy mug or glad, gently press down on each potato until it pops and smash down to about ½-inch thickness.
- Bake for 20 minutes. Remove potatoes from oven and turn each with a spatula. Drizzle with olive oil and continue baking for 20 minutes more.
- Once baked, sprinkle with vinegar, salt and freshly ground pepper. Serve hot.
