01 - Preheat oven to 425°F and line a large baking sheet with parchment paper.
02 - Place sweet potato medallions in a single layer on the prepared baking sheet.
03 - Drizzle with olive oil, then sprinkle with sea salt, black pepper, and ground cinnamon if desired. Toss to coat each piece evenly, ensuring a single even layer.
04 - Roast for 25 to 30 minutes, flipping medallions halfway through, until golden and fork-tender.
05 - Remove baking sheet from the oven and immediately drizzle medallions evenly with honey. Allow to sit for 2 to 3 minutes so the honey absorbs into the potatoes.
06 - Transfer medallions onto a serving platter and garnish with chopped fresh parsley if desired. Serve warm.
