01 - Preheat oven to 425°F (220°C). Line a large baking sheet with parchment paper.
02 - Arrange the sweet potato medallions in a single layer on the prepared baking sheet.
03 - Drizzle olive oil over the medallions, then sprinkle with sea salt, black pepper, and cinnamon if using. Toss to coat evenly and spread back into a single layer.
04 - Roast in the oven for 25–30 minutes, flipping halfway through, until the medallions are golden and fork-tender.
05 - Remove from the oven and immediately drizzle honey evenly over the warm medallions. Let rest for 2–3 minutes so the honey absorbs into the potatoes.
06 - Transfer to a serving platter, garnish with fresh parsley if desired, and serve warm.
