Preheat your oven to 425°F (220°C) and line a baking sheet with parchment for easy cleanup.
Cut the sweet potatoes into evenly sized pieces, about 1/2 to 3/4 inch thick. This helps them roast uniformly.
Toss the potatoes with olive oil, salt, and pepper until every piece glistens. Arrange them in a single layer on the baking sheet to ensure crisp edges.
Roast for 18–22 minutes, flipping once halfway through, until the centers are tender and the edges are caramelized.
Meanwhile, in a small bowl, whisk together chili crisp, rice vinegar, soy sauce, honey, and garlic powder. This becomes your glossy glaze.
When the potatoes come out of the oven, transfer them to a heatproof dish or keep them on the baking sheet. Drizzle the chili crisp glaze over the hot potatoes and toss gently to coat.
Return to the oven for 2–3 minutes to let the glaze set and the flavors meld. Keep an eye on them so they don’t burn.
Finish with a sprinkle of sesame seeds and chopped cilantro or green onions for color and freshness.
Taste and adjust with a tiny squeeze of lime or more chili crisp if you like, then serve hot.
