Savory Parmesan Sweet Potato Chips (Oven Baked)

A hot oven does the work to create these crispy and delicious sweet potato chips. With only 5 simple ingredients in this easy, savory recipe, you do only a few minutes of work before the oven does the rest - no air fryer or deep fryer required.

Sweet potatoes are so often paired with brown sugar and cinnamon. A great combination that’s also super predictable. Don’t overlook savory sweet potatoes! Flavoring a sweet potato with ingredients you’d use for white potatoes can lead to delicious and unexpected results.  

For this recipe we are skipping the sugar and maple syrup found in sweet potato casseroles and other more traditional sweet potato dishes. It’s not sprinkled on the chips or found in the dip. These are 100% savory.  

They're the perfect game day snack or easy side dish to make alongside some cheeseburger sliders or pulled pork sandwiches.

Ingredients for Sweet Potato Chips

• Sweet Potato - Choose one large sweet potato or two small ones. Any type of sweet potato will work here.
• Vegetable oil - You want a high heat oil with a very light flavor to it, so vegetable oil or canola oil is a great choice.
• Parmesan cheese - Freshly grated Parmesan cheese will to the best job of melting on the warm chips and sticking to them.
• Garlic powder -
• Salt - All chips need a little salt. Choose your favorite salt for this recipe.

Tips on Baked Sweet Potato Chips 

Cut your potato slices thin and keep them all about the same size. If you have both large and small slices, cut the large ones in half. Keeping the sweet potato slices uniform in size will help ensure a crispy chip. 

Rotate your baking sheets when you flip the chips midway through baking. Change both which rack the chips were on as well as which side of the baking sheet was facing the back of the oven. 

Every oven is different and nothing points out uneven oven temperatures like making chips, so keep an eye on your chips towards the end of the baking time. They can burn quickly. If you find some chips are done and some are not, remove the crispy ones and put the remaining chips back into the oven for 2 minutes. Repeat this as needed until all of the chips are crispy. 

Chips will crisp up as they cool. If the middle of the chip is firm, it’s done, even if it’s not crunchy right out of the oven. Let it come to room temperature before enjoying.  

Parmesan sweet potato chips are best enjoyed immediately after you bake them. They’re a great afternoon snack or as a fun side dish to sloppy joes or bbq chicken. 

Don’t want cheese on your chips? Skip it! Just add a bit of salt to the hot chips when they come out of the oven if you decide to skip the Parmesan cheese. 

How to Make Parmesan Sweet Potato Chips 

Heat the oven to 400 degrees.

Peel or scrub your sweet potato. 

Using a mandoline slicer set to the thinnest setting, slice your sweet potatoes into very thin slices.

Lay sweet potato slices out on 2 baking sheets lined with parchment paper. 

Bake the slices for 10 minutes. 

Remove the trays from the oven and flip the slices over. 

Return to the oven - rotating the trays when you put them back in - and bake for another 10 minutes. 

Remove from the oven and sprinkle slices with Parmesan cheese. 

Allow to cool to room temperature on the baking sheets before serving.
