How to Make these Oven Baked Sweet Potato Chips EXTRA Crispy

Usually, the key to crispiness in potato chips is deep frying or kettle cooking. Which, unfortunately, involves tons of oil (and usually it’s an inflammatory vegetable oil). Luckily, there are a few tricks you can use to get you oven baked sweet potato chips crave-ably crispy without frying.

Thin slices make for crispy baked chips.

Already, sweet potatoes have a sturdier texture that makes them primed for crispiness. And, they have a lower water content than white potatoes which makes for easier and faster crisping!

For best results, do your best to slice your sweet potatoes as thinly as possible. Thicker slices will likely retain some of the starchy softness in the potatoes. But, if you can get them really thin (like ⅛-inch thick), you’ll have the best chances for crispy baked chips!

For these oven baked sweet potato chips, I used a mandolin for easier slicing. (And, of course, I always use my safety gloves!) It’s a nifty tool that allows you to set a thickness for your slices so you don’t have to fuss with using a knife.

Of course, a mandolin isn’t necessary to make your oven baked sweet potato chips. But, it can be a big help—and could be a smart investment if you’re a big homemade veggie chip fan!

Take advantage of a wire baking rack.

Whether you’re craving crispy chips or crispy homemade fries, a baking rack is your best tool. Usually, we put our chips right onto a baking pan and into the oven like we’d do for roasting vegetables. But, this method doesn’t allow the heat to circulate around your chips.

Instead, a baking rack leaves room underneath your oven baked sweet potato chips so the heat can reach them on all sides. That way, you don’t end up with chips that are half-crispy on the edges but half-soft on the bottom!

If you’re into veggie chips or you’ve been trying to get your homemade fries crispier, I highly recommend getting a wire baking rack for your kitchen. Give it a try with these oven baked sweet potato chips and, trust me—you’ll be glad you did!
