Print Recipe


  • A mandolin with waffle/crosshatch blade, or a sharp knife
  • Deep fryer, or heavy skillet with oil


  • vegetable oil for frying
  • 3 large sweet potatoes or yams, peeled, with the ends cut off
  • 1 tbsp Sea salt coarse, or to taste
  • Kickin' Remoulade Sauce optional, for dipping


  • Turn your mandolin to the crosshatch (or waffle), setting. Make sure the blade is set with the crosshatch ridges (not the straight-edge blade) in the position to cut the potatoes.
  • Using the protective handle/cover, swipe the spud down the mandolin over the ridged blade. Discard the first slice.
  • Turn the potato 90°, and swipe down the mandolin again...you'll now have your first waffle fry. Repeat until all sweet potatoes are sliced.
  • Add the slices to a large bowl filled with water and allow to soak for at least 30 minutes, or up to 24 hours.
  • Meanwhile, heat the oil in a large skillet, or a deep fryer, to 350°F.
  • Drain the slices and dry them off well with a kitchen towel. Quickly fry in batches...only about 1 to 2 minutes per batch, or until fries are starting to turn a little brown.
  • Remove from oil and place on paper towels. Immediately sprinkle with sea salt.
  • Serve with your favorite dipping sauce, such as Kickin' Remoulade Sauce



If you don't have a mandolin with a crosshatch blade, then you can use a sharp knife to carefully slice thin slices of the potatoes.  The thicker the slice, the longer it will take for them to become crispy.

To bake the chips:  No need to soak the chips in water.  Simply coat all over with olive oil and then bake at 350°F for 2 hours, moving them around on the baking dish every 30 minutes or so.
To air-fry the chips: Soak them for 30 minutes, dry them off, and then lightly spray them with oil.  Air-fry on 350°F for 15 minutes. 
The chips will get even crispier after they have rested a couple of minutes.
These crosshatch sweet potato chips are best served within an hour or two of frying them.
