Start soaking the cashews for the Creamy Cilantro Sauce (or make it in advance; you can also soak the cashews the night before for easy day-of prep). If you’re planning to make the Creamy Cilantro Dressing, skip this part.
Preheat oven to 450°F.
Wash the sweet potatoes and slice them in half. Place on a parchment paper lined baking sheet and rub lightly with olive oil, just enough to coat. Sprinkle with kosher salt. Bake until tender and lightly browned on the edges, about 25 to 35 minutes depending on the size of the potatoes.
