Air Fryer Sweet Potato Chips

If you ever craved something crunchy but didn’t want the guilt of deep frying, these air fryer sweet potato chips are honestly a game changer. I’ve made this recipe so many times in my kitchen, and still every batch feels a little exciting… because getting that perfect crisp is kinda satisfying.

These chips are naturally sweet, lightly salty, and super crispy when done right. Plus, they fit perfectly into healthy snack recipes, low oil snacks, and even gluten-free diets which a lot of people in the US are looking for these days.

Why This Recipe Works So Well

• Uses very little oil compared to deep frying
• Sweet potatoes are rich in fiber, vitamin A, and antioxidants
• Air fryer makes them crispy without burning (if you watch closely)
• Perfect for healthy snacking, game nights, or quick cravings

Honestly, once you try homemade sweet potato chips in air fryer, store-bought chips just don’t hit the same.

Ingredients

• 2 medium sweet potatoes (about 1 lb total)
• 1 to 1.5 tablespoons olive oil
• ½ teaspoon sea salt
• ¼ teaspoon black pepper
• Optional:
  • ½ teaspoon paprika (for smoky flavor)
  • ¼ teaspoon garlic powder
  • Pinch of cayenne pepper (if you like a little heat)

Ingredient Notes

• Sweet Potatoes: Try to pick ones that are long and evenly shaped. Makes slicing easier. Thin slices = crispier chips.
• Olive Oil: Don’t overdo it. Too much oil actually makes chips soggy… learned that the hard way.
• Seasoning: Keep it simple first time. Then experiment later.

Equipment You’ll Need

• Air fryer (basket style works best)
• Mandoline slicer or sharp knife
• Mixing bowl
• Paper towels

Step-by-Step Instructions

1. Wash and peel

Wash the sweet potatoes properly. You can keep the skin on, but I usually peel it for smoother chips.

2. Slice very thin

Use a mandoline slicer if possible. Aim for about 1/16 inch thickness. If slices are uneven, some chips will burn and some stay soft.

3. Soak in cold water

Place slices in cold water for at least 20–30 minutes. This removes starch and helps crispiness.

4. Dry completely

This step is important but many people skip it. Pat dry using paper towels. Wet slices = no crisp.

5. Preheat air fryer

Set air fryer to 350°F (175°C) for about 3–5 minutes.

6. Toss with oil

Add slices to a bowl, drizzle olive oil, and toss gently. Don’t dump oil all at once.

7. Add seasoning

Sprinkle salt, pepper, and any optional spices. Mix evenly but carefully.

8. Arrange in basket

Place slices in a single layer. Don’t overcrowd, otherwise they steam instead of crisp.

9. Air fry in batches

Cook for 8–12 minutes, flipping halfway. Keep checking after 7 minutes because they burn quickly.

10. Remove and cool

Take chips out when edges are slightly brown. They will crisp more as they cool.

11. Repeat batches

Do the same with remaining slices.

12. Taste and adjust

Add a little extra salt if needed while still warm.

Pro Tips

• Some chips may not crisp perfectly, and thats normal
• Thin slices matter more than anything
• If chips feel soft, put them back for 2–3 minutes
• Don’t stack hot chips, they get soggy
