1: Wash the potatoes well while keeping their skin on and boil them in water for about 5 minutes.
2: Drain the potatoes and cut them into thin slices, keeping the skin on.
3: Heat a grill or non-stick pan until hot and cook the potato slices without overlapping them, flipping halfway through until golden bubbles form.
4: Prepare the seasoning by mixing olive oil, halved garlic, salt, and rosemary in a bowl and microwaving for about 1 minute at 600 watts.
5: Remove the potatoes from the grill, place them on a serving plate, and drizzle with the flavored oil before serving.
