Ingredients:
- 3½ lbs. med. yellow potatoes, washed
- 1/4 cup kosher salt
- To taste salt and freshly ground black pepper
Ingredients for infused butter:
- ½ cup unsalted butter
- 4 cloves garlic, thickly sliced
- 4 sprigs fresh rosemary, or to taste
- 4 sprigs fresh thyme, or to taste
Directions:
- Place potatoes into a 5-quart stockpot and cover with 3 quarts of cold water. Add kosher salt and bring to a simmer over high heat. Reduce heat to medium-low and simmer gently until potatoes are just tender, 15 to 20 minutes. Remove from heat and drain well.
- Let potatoes cool just until they’re safe to handle. Transfer potatoes onto a sheet pan and continue cooling to room temperature.
- Make four or five shallow cuts down the sides of each potato, about every inch or so, to ensure the skin splits evenly when smashed.
- Refrigerate until completely chilled and ready to smash; 8 hours to overnight is best.
- Combine butter, sliced garlic, rosemary and thyme in a small pan over medium heat. Cook, stirring occasionally, until butter melts and begins to bubble and garlic softens and starts to turn translucent, 3 to 5 minutes. Remove from heat.
- Preheat the oven to 450 F. Line 2 metal baking sheets with silicone baking mats and generously brush on some of the infused melted butter.
- Remove potatoes from the fridge and gently smash each between two pieces of plastic using a flat bottom jar until 1/2- to 3/4-inch thick. Season generously with salt and pepper on both sides, being careful not to break potatoes up into small pieces.
- Transfer onto a sheet pan, being careful not to overlap potatoes. Very generously drizzle and brush most of the melted butter on top.
- Bake potatoes in the preheated oven until well browned and crunchy around the edges, 35 to 45 minutes.
- Meanwhile, place the pan with the remaining garlic and herb butter back over medium-low heat. Cook, stirring, until garlic starts to turn a very light golden brown, 3 to 4 minutes. Remove from heat and reserve.
- Carefully transfer potatoes onto a serving platter and scatter over the golden brown slices of garlic. Crumble the toasted herbs on top if desired. Serve immediately.
