Ingredients

  • kosher salt, to taste
  • 2 1/2 lbs yukon gold potatoes, peeled, sliced 3/16-inch thick on a mandoline
  • 2 garlic cloves
  • 8 tablespoons unsalted butter
  • 1 tablespoon fresh flat-leaf parsley, chopped
  • 1 teaspoon chopped fresh thyme
  • freshly ground pepper, to taste

Method

  • Bring a large pot of water to a boil over high heat. Salt the water. Add the potato slices and cook until they are slightly softened but not completely tender, about 8 minutes. Drain the potatoes well and let cool.
  • Prepare a charcoal or gas grill for indirect grilling over medium-high heat.
  • Using the side of a chef's knife, smash the garlic cloves and sprinkle with a generous pinch of salt. Continue smashing and scraping the garlic into a paste.
  • In a small saucepan over medium heat, melt the butter. Stir in the garlic paste, parsley and thyme, and season with salt and pepper.
  • Spray a mesh grill pan with nonstick cooking spray. Place 2 potato slices in the center of the grill pan, then create 2 separate rings of potato slices: Starting with the inner ring, arrange the slices, slightly overlapping the center slices as well as the previous slice, to create a fanned effect. Then form an outer ring of potato slices, slightly overlapping the inner ring.
  • Brush the first layer of potatoes with some of the garlic-herb butter and season with salt and pepper. Repeat to create a second layer on top of the first one. Brush the top layer with garlic-herb butter and season with salt and pepper.
  • Transfer the grill pan to the center of the grill and cover the grill. Cook, basting the potatoes with garlic-herb butter every 10 minutes, until they are tender and browned on top, 35 to 45 minutes.
