01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - Peel potatoes and slice lengthwise into 1/2-inch thick slabs. Using a heart-shaped cookie cutter, cut out heart shapes from each slab. Reserve scraps for another use.
03 - In a large bowl, combine olive oil, minced garlic, rosemary, thyme, salt, and pepper. Whisk to blend.
04 - Add heart-shaped potatoes to the bowl and toss until evenly coated with marinade.
05 - Arrange potatoes in a single layer on the prepared baking sheet, ensuring pieces do not overlap.
06 - Roast for 30 to 35 minutes, flipping halfway through cooking, until golden brown and crisp at edges.
07 - Transfer to a serving platter. Sprinkle with chopped parsley and flaky sea salt if desired. Serve immediately while hot.
