We just love dishes that are spectacular in their simplicity. Let the ingredients shine!

This appetizer or side dish is no exception. The chips are light and airy, but so amazingly delicious. A quick fry and a sprinkle of sea salt are all that’s needed. They can be deep-fried, baked, or cooked in your air fryer! They are wonderful served with our Kickin’ Remoulade Sauce!

The preparation for these chips really couldn’t be easier.

We use our mandolin to get the beautiful crosshatch pattern, but also very thinly sliced sweet potato slices will work just fine, too.


On most mandolins, there will be a crosshatch symbol on the dial on the side of the tool.

Turn the dial to the crosshatch symbol and then carefully remove the blade in the middle of the mandolin.

Now, insert it back in with the blade with the ridges is facing up. (See photo for reference).

Take one of your peeled sweet potatoes, and slice one end off so you have a flat, smooth edge.

Now, carefully slide the potato, cut-side down, across the blade. You can discard the first cut. You’ve now begun the crosshatch process.

Simply turn the potato to a 45° angle and slide it across the blade again. Take a look! You’ve just made your first crosshatch chip!

EXPERT TIP: It is important to handle the slice of the chips very carefully. Don’t rush and try and keep the edge of the potato flat and smooth. We recommend cutting the opposite end of the potato off as well. This will allow you to easily attach the safety guard to the end of the potato as you continue cutting, getting closer and closer to the end of the potato.

We find that 3 large sweet potatoes give you a nice large serving of crosshatch sweet potato fries.

This recipe will comfortably feed 4 to 6 people as an appetizer or a side dish.

Soaking the cut sweet potatoes is an important step to ensure crispy, perfectly cooked chips.

Soak the cut spuds in a large bowl of water for a minimum of 30 minutes. You can actually soak them overnight, and they’ll be just fine.

EXPERT TIP: If you prefer to bake the sweet potato chips, then you can skip soaking them. Simply brush them with a little olive oil all over, and then bake at 350° F for about 2 hours, moving them around on the pan every now and then. If you want to air fry your chips, we do recommend soaking them for 15 to 20 minutes, then dry them off, toss (or spray) them in oil, and then air-fry for 15 minutes at 350°F.

Baking and air-frying these chips are absolutely wonderful, and of course, a little more healthy.

But these chips are so thin, they really only get a quick fry in the oil if you deep fry them.

EXPERT TIP: You don’t want your oil too hot or they will burn. If your oil is not hot enough, they’ll cook longer and could absorb more oil than is desired and be a little mushy. We find that 1 minute to 2 minutes in 350°F hot oil delivers perfectly golden chips.

These babies are honestly so delicious by themselves, that a nice sprinkling of coarse sea salt is often all that’s needed.

We got the inspiration to make these when we ordered something similar at a gastropub in Omaha, Nebraska.

They work wonderfully as an appetizer or a side dish to a killer-good burger such as our Mushroom-Swiss Burger!

But, you know us, we love a good sauce.

A good dipping sauce is a perfect accompaniment for these crosshatch sweet potato fries.

Our Kickin’ Remoulade has just a touch of heat, which is the perfect match against the sweetness of the chips. Homemade Ranch is wonderful, too.

Every time we serve these, we get rave reviews.

We often serve them for guests as an appetizer or a side dish for a BBQ, but they’re so easy, we love to whip up a batch for an afternoon snack.

As the Loon says, “You definitely can’t eat just one of these chips! They are insanely good! And with the sauce? Forget about it!”

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.
