spicy sweet potatoes

  • 1 sweet potato
  • 1 teaspoon diamond kosher salt
  • 1/4 tsp ground cayenne pepper
  • 1/4 teaspoon ground coriander
  • a pinch ground black pepper
  • enough oil to lightly coat the sweet potatoes

cilantro sauce

  • 1/2 cup cilantro- you can include the stems but you’ll get a smoother sauce if you leave them out
  • 2-3 scallions
  • 2 teaspoon rice vinegar
  • a pinch of salt


make the cilantro sauce

  1. roughly chop the cilantro and scallions
  2. combine all ingredients in the bowl of a food processor fitted with the metal blade
  3. process until smooth, scraping the bowl as neccessary

bake the sweet potatoes

  3. mix together salt and spices in a small bowl until combined
  4. coat the sweet potatoes with oil and then toss with salt mixture
  5. arrange potatoes in a single layer on a sheet pan or in a cast iron skillet
  6. bake until tender, this will vary depending on the thickness of the slices but approximately 15 minutes, flipping mid way for even browning.
