How to Make Air Fryer Roasted Sweet Potatoes
Step 1: Prep the Potatoes
Wash the sweet potatoes thoroughly under cold water. Peel them if you prefer a smoother texture, or leave the skin on for extra fiber and bite. Use a sharp knife to cut the potatoes into uniform cubes, about half an inch to one inch thick. Consistent size is key to even cooking.
Step 2: The Secret Rinse
Place the cut cubes in a large colander. Rinse them under cold running water for at least 30 seconds to remove surface starch. This helps prevent a tough or chewy texture. After rinsing, lay the cubes on a clean towel and pat them completely dry. Moisture is the enemy of crispiness, so don’t skip this step.
Step 3: Season
Transfer the dried cubes to a large mixing bowl. Drizzle with your choice of oil and toss to coat. Sprinkle in your preferred seasoning blend, either sweet and spicy or savory herb. Mix well until each piece is fully coated with oil and seasoning.
Step 4: Air Fry to Perfection
Preheat your air fryer to 400°F or 200°C. Once heated, place the seasoned sweet potatoes in the basket in a single layer. Avoid stacking or overcrowding so air can circulate freely. Cook for 15 to 20 minutes, shaking the basket every 5 to 6 minutes to ensure even crisping. They are done when golden on the outside and easily pierced with a fork.
Pro-Tips for Foolproof Crispy Potatoes
- Always Rinse First
Removing surface starch is the trick to achieving that creamy interior with a crisp outer edge. - Cut Evenly
Uniform cube sizes help all pieces cook at the same rate. Uneven chunks can result in a mix of burned and undercooked potatoes. - Don’t Crowd the Basket
Sweet potatoes need room to crisp. If necessary, cook in batches for best results. - Shake During Cooking
Gently toss the basket every five minutes to prevent sticking and get that golden color on all sides. - Use Enough Oil
A light coating of oil helps the potatoes brown and crisp. Too little can leave them dry and unevenly cooked.
Serving and Storage Tips
Serving Ideas
Serve your air fryer roasted sweet potatoes hot, straight from the basket. They make a great side with grilled meats, burgers, or scrambled eggs. You can also toss them into salads, grain bowls, or wrap them in warm tortillas for a quick veggie taco.
Storage Instructions
Let leftovers cool to room temperature before storing. Place them in an airtight container and refrigerate for up to four days.
How to Reheat
To bring back the crisp, reheat the potatoes in the air fryer at 375°F for about five minutes. Avoid the microwave if possible, as it can make them soggy.
Helpful Notes
- Peeling is Optional
Leaving the skin on adds texture and extra nutrients. Just scrub them well if you skip peeling. - Cube Size Impacts Texture
Smaller cubes turn out crispier and cook faster. Larger ones stay softer in the center. Choose based on your preference. - Season After Rinsing and Drying
Don’t add seasoning until the potatoes are fully dry. Wet potatoes can cause the spices to clump and the texture to suffer. - Batch Cooking Helps
If you’re making a large amount, cook in batches. The second batch usually cooks faster since the air fryer is already hot. - Try Different Oils
Olive oil and avocado oil both work great. For a subtle flavor twist, you can try garlic-infused oil or chili oil.

Frequently Asked Questions
How do you roast sweet potatoes in the air fryer?
Cut the sweet potatoes into evenly sized cubes. Rinse to remove excess starch, then dry them thoroughly. Toss with oil and your favorite seasoning. Air fry at 400°F in a single layer for 15 to 20 minutes, shaking the basket every few minutes for even crisping.
How many minutes should I cook sweet potatoes in an air fryer?
Cook time depends on the size of the cubes. For half-inch pieces, 15 to 18 minutes works well. Larger cubes may take up to 20 minutes. Always shake the basket during cooking for even results.
Can I air fry sweet potatoes with the skin on?
Yes, you can. Just make sure to scrub them well before cutting. The skin adds extra fiber and gives a slightly firmer texture when roasted.
Why are my sweet potatoes not crispy in the air fryer?
Several reasons can lead to this. Too much moisture is the top issue, so always dry the cubes after rinsing. Avoid overcrowding the basket and make sure to toss with a bit of oil before air frying.
Why do you soak sweet potatoes in water before air frying?
Soaking or rinsing removes surface starch. This helps the interior stay tender while the outside becomes crispy. It also helps prevent the potatoes from becoming too tough or chewy.
Are air-fried sweet potatoes still healthy?
Yes. They’re naturally rich in fiber and vitamins A and C. Air frying uses much less oil than deep frying, so you get a healthier side or snack without sacrificing flavor or texture.
