Ingredients and Easy Swaps

• Two large sweet potatoes (about 1 lb / 450 g)
• 2 tablespoons avocado oil (or olive oil)
• 1 teaspoon sea salt (flaky or fine)
• 1/2 teaspoon smoked paprika
• 1/4 teaspoon freshly ground black pepper
• 1/4 teaspoon garlic powder (optional)
• pinch cayenne pepper (optional)
• cinnamon (optional)

How to Slice and Bake

1. Preheat the oven to 375°F (190°C) and line a baking sheet with parchment paper or a silicone baking mat.
2. Wash and dry the sweet potatoes; leave the skin on or peel if desired.
3. Use the mandoline guard or wear a cut-resistant glove before slicing.

4. Slice the sweet potatoes on a mandoline at the thinnest setting (~1/16 inch / 1.5 mm) or slice evenly by hand.

   

5. Toss the slices in a large bowl with 2 tablespoons avocado oil to coat evenly.
6. Season with sea salt, smoked paprika, freshly ground black pepper, and any optional spices; gently toss to distribute.
7. Arrange the slices in a single layer without overlapping on the prepared baking sheet (use two sheets or bake in batches if needed).

8. Bake for 15 minutes, then flip each chip and bake another 10–15 minutes, watching closely until golden brown and crisp at the edges.

   

9. If chips are soft after baking, return them to the oven at 375°F (190°C) for 2–3 minutes, watching carefully.
10. Transfer the chips immediately to a cooling rack and let them cool completely to reach maximum crispness.

11. Optional (air fryer): cook slices at 375°F (190°C) for 12–15 minutes, shaking the basket halfway through and working in small batches.

    

Pro Tips for Crispy Results

Nailing the perfect crispy sweet potato chip takes a few insider moves. First and foremost: slice thin and consistent. I learned the hard way that thicker or wavy slices lead to some burnt and some undercooked chips—not fun!

Then, don’t cram your baking sheet. Chips need breathing room so they crisp instead of steaming. Flipping halfway is a must—it’s like giving each side its moment to shine and turn golden.

In the last five minutes, watch carefully. Sweet potatoes can go from perfect to burnt super fast, so set a timer and peek often, especially with ovens that run hot or new batches.

When tossing with seasoning, be gentle. You want even coverage without breaking those delicate slices. And for an extra crunch boost, sprinkle some finishing salt right after baking while the chips are still warm.

Finally, patience really pays off. Let your chips cool fully on a rack before storing. I know it’s tough to wait, but rushing this step can make them soggy. Trust me, the payoff is crisp perfection.

Flavor Twists and Shortcuts

Ready to jazz up your sweet potato chips? Here are some of my favorite ways to change things up:

• Spicy Boost: Add a pinch of cayenne pepper or chili powder for some heat in the seasoning mix.
• Sweet & Cozy: Toss with cinnamon and a little maple syrup before baking for a snack that tastes like dessert. If you love warm cinnamon flavor, try our Cinnamon Swirl Bread recipe.
• Herb Magic: Mix dried rosemary or thyme into the oil and salt for an herby savory flavor that’s super fragrant.
• Air Fryer Shortcut: Cook the slices at 375°F (190°C) for 12-15 minutes, shaking the basket halfway through. This makes crisping faster with less oil.
• Oil Swaps and Allergies: You can use olive oil or coconut oil instead of avocado oil. This recipe is naturally gluten- and dairy-free.

One of my family’s favorites is sprinkling nutritional yeast on top after baking for a cheesy, umami flavor without any dairy—it’s a total crowd-pleaser!

Serving, Storing, and Make-Ahead Tips

These crispy sweet potato chips shine best at room temperature, fresh from the cooling rack when their crunch is at its absolute peak. Serve them with creamy dips like hummus, guacamole, or a zesty yogurt sauce for a snack that feels special but not heavy.

For parties, arrange chips in a bright bowl surrounded by colorful veggie sticks and some olives for a pretty and tasty snack platter. They pair surprisingly well with crisp white wine or sparkling water with a squeeze of lemon, too!

To store leftovers, make sure chips have cooled completely on the rack, then pop them in an airtight container at room temperature. They stay crunchy for 2-3 days but will soften if left too long. If that happens, just flash-toast them in the oven for a couple of minutes to revive their crisp.

Avoid refrigerating because moisture will make chips soggy. For longer storage, freeze cooled chips in a sealed bag, then re-crisp them in the oven before serving for a quick refresh.

Common Questions Answered

How thin should I slice the sweet potatoes for crispy chips?

Aim for about 1/16 inch (roughly 1.5 mm). Thin, even slices are a must for perfect baking and crunch. If you have a mandoline, use its thinnest setting for ease and consistency.

Can I use a different oil instead of avocado oil?

Absolutely. Olive oil, coconut oil, or other neutral oils that can handle heat work fine. Avocado oil just stands out because it handles oven heat well without adding flavor.

Do I need to peel the sweet potatoes?

Nope! Leaving the skin on adds fiber, color, and texture. Only peel if you want a smoother result or don’t love skin texture.

What causes soggy chips and how can I prevent it?

Soggy chips usually come from slices that are too thick or uneven, overcrowding the pan, or skipping the flip halfway through baking. Keep slices uniform, give them plenty of space, and flip each one to get crisp edges on both sides.

Can I make these in an air fryer?

Yes! Air fry at 375°F (190°C) for 12–15 minutes, shaking or turning the basket halfway through. Work in small batches so the chips have plenty of room.

How should I store leftovers so they stay crisp?

Once completely cool, store chips in an airtight container at room temperature. They’re best eaten within 2–3 days. Avoid refrigeration to keep them from turning soft.

My chips aren’t crisp after baking — any tips?

If they’re soft, pop them back in the oven at 375°F (190°C) for 2–3 minutes, watching carefully. Cooling on a rack before storing also helps preserve crispness.

Can I prep these ahead or freeze them?

You can slice and season ahead of time, then bake fresh when you want them. For longer storage, freeze fully cooled chips in a sealed bag, and reheat in the oven to crisp before enjoying. Keep in mind that freezing might change the texture slightly.

Any safety tips for using a mandoline?

Definitely use the guard or a cut-resistant glove and slice slowly and carefully. A sharp blade helps stop slipping and gives clean, even slices.
