Easy Air Fryer Sweet Potatoes are crispy outside and tender inside. They make a quick, versatile side dish and are ready in about 25 minutes.
If you enjoy sweet potatoes, these air fryer sweet potatoes are a must-try. They develop a crisp exterior while staying soft in the center — a welcome alternative to mashed or oven-roasted sweet potatoes. The air fryer delivers excellent texture with minimal fuss, and this method is one of the quickest ways to get tender, flavorful cubes.
Serving size can vary depending on appetite. Two cups of diced sweet potato is roughly one large or two medium sweet potatoes and will serve 2 people as a generous side or up to 4 as a smaller portion.
Ingredient notes:
Sweet potato – Two cups diced sweet potato equals about one large or two medium sweet potatoes.
Chili powder – Adds warmth and depth. Substitute garlic-herb seasoning, chipotle, za’atar, or any seasoning blend you prefer.
Avocado oil spray – Olive oil spray or another nonstick spray works too. Lightly spraying the air fryer basket prevents sticking and helps the edges crisp.
Method
First: Dice the sweet potatoes. No need to peel—just trim the ends and cut into evenly sized pieces. I like to slice into rounds, then quarter them so the cubes cook evenly.
Second: Season the potatoes. Place the diced potatoes in a bowl, drizzle with olive oil, and stir to coat. Add chili powder, salt, and pepper, then toss until evenly seasoned.
Third: Air fry. Lightly spray the air fryer basket with avocado or olive oil spray, spread the sweet potatoes in a single layer without overcrowding, and air fry at 400°F (about 200°C). Cook for 20–25 minutes, shaking or tossing the basket halfway through so the pieces crisp evenly. Check for golden-brown edges and tender centers; if needed, cook a few minutes longer.
Tips and FAQ
Make sweet potato fries: Slice the sweet potatoes thinly into fry shapes and air fry the same temperature. Watch them closely and check every 4 minutes — thinner pieces will cook faster.
Serving ideas: These pair well with ketchup, mayo, chipotle aioli, pesto, or your favorite dipping sauce. They also complement grilled proteins, roasted vegetables, or salads.
They’re done when the exterior is golden brown and the interior is tender. Taste a piece after 20 minutes and continue cooking in 2–5 minute increments if needed.
Yes. Reheating in the air fryer or oven will help restore some crispness. Microwave reheating is faster but may soften the texture. For best results, reheat at 400°F in the oven for about 10 minutes or briefly in the air fryer.
