Preheat oven to 425°F and line a large baking sheet with parchment paper.
Toss the sweet potatoes with olive oil, salt, pepper, smoked paprika, garlic powder, and maple syrup (if using). Spread evenly on the baking sheet, leaving space between pieces for crisping.
Roast 30–35 minutes, flipping halfway through, until deep golden and slightly crisp on the edges.
While the sweet potatoes roast, make the whipped feta: Combine feta (or goat cheese), yogurt, olive oil, lemon juice, garlic, sea salt, pepper, and water in a food processor or blender. Blend until smooth and creamy, scraping down sides as needed. Adjust thickness with a splash more water or lemon juice.
Spread the whipped feta across a serving plate. Pile the hot roasted sweet potatoes on top. Drizzle with hot honey, sprinkle with toasted nuts or seeds, herbs, and a pinch of flaky salt. Serve warm. Enjoy!
