01 - Preheat your oven to 425°F. Line a large baking sheet with parchment paper.
02 - Peel the potatoes and slice them into 0.5-inch thick rounds.
03 - Using a small heart-shaped cookie cutter, carefully cut heart shapes from each potato slice. Reserve the trimmings for alternative culinary applications, such as soups or hash browns.
04 - In a large mixing bowl, thoroughly toss the heart-shaped potato pieces with olive oil, sea salt, freshly ground black pepper, garlic powder, and dried thyme (or rosemary) until uniformly coated.
05 - Evenly arrange the seasoned potatoes in a single layer on the prepared baking sheet, ensuring no pieces overlap to promote even cooking.
06 - Roast for 25 to 30 minutes, turning the potatoes halfway through the cooking process, until they achieve a golden-brown hue and crisp edges.
07 - Transfer the roasted potatoes to a serving platter. If desired, garnish with fresh parsley and a final sprinkle of flaky sea salt. Serve immediately while hot.
