🍠 Ingredients You’ll Need
Simple is best—and this recipe proves it. Here’s what you’ll need:
- 2 medium sweet potatoes: Scrubbed and rinsed. Leave the skin on for extra fiber and a rustic look, or peel if preferred.
- 1 tablespoon avocado oil: Or any neutral oil with a high smoke point like olive oil, grapeseed, or sunflower oil.
- 1 teaspoon sea salt: Fine sea salt or pink Himalayan salt works beautifully.
That’s it! No preservatives, no added sugars, and no unpronounceable ingredients.
🔪 Preparation: The Key to Perfect Chips
Step 1: Wash and Prep
Start by rinsing and scrubbing your sweet potatoes thoroughly. These root veggies often have residual dirt from the ground, so give them a good scrub under cool water. Dry them well with a towel.
Slice off the ends to create flat surfaces for safer slicing.
Step 2: Thinly Slice
Using a mandoline slicer is highly recommended here for uniform, thin slices—about 1/32 inch thick is ideal. Even thickness ensures all the chips cook at the same rate.
If you don’t have a mandoline, a very sharp knife will do the job, but be patient and try to keep the slices consistent.
Tip: The thinner the slice, the crispier the chip. Thicker slices may result in a chewy texture.
🛢️ Seasoning and Coating
Place your sweet potato slices in a mixing bowl. Drizzle in the avocado oil and sprinkle the salt over top. Use clean hands or tongs to gently toss until every slice is lightly coated.
Make sure not to over-oil; you want just enough to help the chips crisp up, not become greasy.
🌬️ Air Frying Instructions
Step 1: Preheat
Preheat your air fryer to 360°F (182°C). This temperature is perfect for slow, even cooking that allows the moisture to escape and the chips to crisp up without burning.
Step 2: Layer the Chips
Place the chips in a single, even layer in the air fryer basket or tray. Do not overlap or crowd them—this is key for that crispy texture.
You may need to work in batches depending on the size of your air fryer.
Step 3: Cook
Air fry the chips at 360°F for 20 minutes, flipping or shaking the basket halfway through the cooking time.
Keep a close eye on them toward the end of the cooking process. Depending on the thickness of your slices and the power of your air fryer, some chips may cook faster than others.
Step 4: Cool and Crisp
Remove the chips and let them cool on a wire rack or paper towel. As they cool, they will continue to crisp up—so don’t be alarmed if they seem a little soft straight out of the fryer.
🧂 Flavor Variations
Want to level up your sweet potato chip game? Try some of these seasoning ideas:
- Sweet & Spicy: Add a pinch of cayenne pepper and cinnamon to the salt.
- Smoky BBQ: Toss with smoked paprika, garlic powder, and a dash of chili powder.
- Zesty Ranch: Sprinkle with ranch seasoning mix after air frying.
- Herbed Delight: Use rosemary, thyme, or oregano with sea salt.
- Maple Sugar Chips: Add a dusting of maple sugar or coconut sugar for a sweet finish.
Note: For best results, add any sugar-based seasonings after air frying to prevent burning.
🧊 Storing Sweet Potato Chips
Homemade chips are best eaten fresh, but you can keep leftovers crisp with these storage tips:
- Let them cool completely before storing to prevent moisture buildup.
- Store in an airtight container at room temperature.
- Add a small piece of paper towel to the container to absorb any moisture.
- Enjoy within 2–3 days for best texture.
If the chips lose their crispness, you can toss them back in the air fryer at 350°F for 2–3 minutes.
🍽️ How to Serve Sweet Potato Chips
Air Fryer Sweet Potato Chips are great on their own, but here are some creative ways to enjoy them:
- As a side dish: Perfect with sandwiches, wraps, or burgers.
- With dips: Try them with hummus, guacamole, tzatziki, garlic aioli, or Greek yogurt ranch dip.
- Snack mix: Combine with roasted nuts and dried cranberries for a DIY snack mix.
- Party platter: Serve as part of a game-day or appetizer spread.
- Topping: Use as a crunchy topping for soups, chili, or salads.
👨🍳 Tips for Success
- Watch closely near the end: These chips go from crispy to burnt very quickly. Keep an eye on them during the last 5 minutes.
- Use uniform slices: Inconsistent thickness means uneven cooking. A mandoline really helps!
- Avoid overcrowding: Space the slices out for the best air circulation.
- Don’t skip cooling: The chips continue to crisp as they cool, so give them a moment before judging their texture.
- Dry sweet potatoes well: Moisture is the enemy of crispy chips. Use a clean towel to blot the slices before seasoning.
💬 Frequently Asked Questions
Can I use purple or white sweet potatoes?
Yes! Different sweet potato varieties work just as well and bring unique colors and flavors to the chips.
Can I make these oil-free?
You can, but the chips may not crisp as evenly. A very light spritz of oil helps with texture and flavor.
What if some chips are done earlier?
Remove any golden or fully crisped chips early and continue cooking the rest. It’s totally normal for a few to finish sooner.
How thin should I slice them?
About 1/32 inch (around 1 mm). Thicker slices will stay chewy, while super-thin slices get crispy.
