01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - Peel potatoes and slice lengthwise into ½-inch thick slabs. Press heart-shaped cookie cutter into each slab to cut out hearts. Set aside scraps for another use.
03 - Whisk together olive oil, minced garlic, rosemary, thyme, salt, and pepper in a large bowl until well combined.
04 - Add heart-shaped potatoes to the bowl. Toss gently until each piece is evenly coated with the herb mixture.
05 - Spread potatoes in a single layer on the prepared baking sheet, ensuring pieces do not overlap for even cooking.
06 - Roast for 30–35 minutes, flipping halfway through cooking. Remove when edges are golden brown and crispy.
07 - Transfer to serving platter. Sprinkle with fresh parsley and flaky sea salt if desired. Serve while hot.
