Sweet Potato Chip Ingredients

This easy recipe only needs 3 of the most basic ingredients.

Sweet Potato – Any color works including orange, white or purple varieties. Or use a blend of the three for a terra chips vibe.

Olive Oil – Helps the chips crisp and prevents sticking. Can sub avocado oil, melted coconut oil, or other high heat oil.

Salt – Enhances flavor and balances the natural sweetness of the potatoes. I like to use coarse kosher salt or sea salt.

How to Make Sweet Potato Chips

This is a shortened form of the full directions found in the recipe card at the bottom of the post.

Step 1

Preheat oven to 400 and line a large baking sheet with parchment paper. 

Step 2

Peel sweet potato and cut in half lengthwise, then slice to 1/4-inch thickness. Try to keep slices a uniform size.

Place sweet potato slices on the prepared baking sheet in a single layer.

Step 3

Drizzle oil over the potato slices and brush to coat and sprinkle with salt. 

Bake in the preheated oven for 25 minutes, checking at the 20-minute mark (the chips can burn quickly). 

Recipe Notes and Tips

• Choose a firm sweet potato without soft spots for the most consistent slices.
• For the most even chips, use a mandoline set to one quarter inch for uniform slicing.
• Thinner slices cook more quickly and can burn so watch closely, especially during the last five minutes.
• A single layer on the baking sheet is essential for crisp chips. Overcrowding leads to steaming and soft chips. If necessary, work in batches.
• Rotating the baking sheet halfway through cooking promotes even browning.
• Chips will continue crisping as they cool on the pan.

Air Fryer Instructions

If you prefer to air fry your sweet potato chips and decrease the amount of oil used, follow these simple recipe adaptations:

1. Preheat air fryer to 350°F 
2. Peel and cut the sweet potato as directed above
3. Lightly coat slices with olive oil until lightly coated (you may only need 1–2 tablespoons).
4. Arrange slices in a single layer in the air fryer basket. Don’t overcrowd and work in batches if needed.
5. Air fry for 10-15 minutes, shaking the basket or flipping the potatoes halfway through.
6. Transfer to a rack to cool and finish crisping.

AIR FRYER NOTES: 

• Begin checking at the 8-10 minute mark. Air fryer chips can go from perfect to burnt very quickly.
• Remove any chips that finish early; let thicker ones continue cooking until golden brown and crisp.

What To Serve with Sweet Potato Chips

Treat these sweet potato potato chips as you would any regular potato chips. They’re a fun and tasty appetizer or snack, or they go great as a side dish with any of the following

• Sloppy Joes, Hamburgers, or Pulled Pork Sandwiches
• Copycat Jimmy John Unwich
• Egg Salad or Chicken Salad

Variations and Flavoring Ideas

You can replace regular salt with seasoned salt, garlic salt, smoked salt or even spice mix blends like taco seasoning or Everything Bagel seasoning. 

Or try any of these other great ideas for a fun flavor twist.

• Cinnamon and sugar for a sweet version
• Smoked paprika or chipotle for a smoky vibe
• Garlic powder and black pepper for a simple savory combo
• Ranch seasoning or BBQ seasoning for classic and kid-friendly flavors
• Finely chopped rosemary or thyme for an earthy and herby twist
• You can also add a little chili oil or sesame oil – or other flavored oil – into the olive oil before brushing onto the potatoes.

More Tips for How to Get Crispy Sweet Potato Chips

• Keep slices the same thickness – use a mandoline set to 1/4 inch or thinnest setting if you have one
• Use enough oil to lightly coat every piece
• Avoid stacking or overlapping and place in an even layer
• Bake on parchment for even heat distribution
• Turn the baking pan halfway through cooking time
• Let chips cool fully before storing.

Storage and Reheating

• Allow the chips to cool entirely before storing. This will prevent condensation from forming inside the storage bag or container. 
• Store completely cooled chips in an airtight container at room temperature for up to three days. Don’t refrigerate leftover chips. 
• If the chips go slightly soft during storage, pop them in a warm oven for five minutes to recrisp them.
