Sweet potatoes are a staple in many kitchens, especially during the holidays. Their natural sweetness and rich flavor make them a favorite for both savory and sweet dishes. But if you’ve never tried crispy air fryer sweet potato cubes, you’re in for a treat.
Whether you’re preparing a side dish for a festive dinner or whipping up a quick snack, crispy air fryer sweet potato cubes are a versatile option that won’t disappoint. In this guide, I’ll take you through every step of the process, share tips for achieving the perfect texture, and offer plenty of variations to suit your taste.
Why Crispy Air Fryer Sweet Potato Cubes?
Air fryers have revolutionized home cooking, allowing us to enjoy crispy, fried-like textures without the excess oil. This method is especially wonderful for sweet potatoes, which naturally caramelize as they cook.
Benefits of Air Frying Sweet Potatoes
- Healthier Cooking: Air frying uses significantly less oil than traditional frying, making it a healthier choice.
- Quick and Convenient: The air fryer reduces cooking time compared to oven roasting.
- Even Crispiness: The hot air circulation ensures every piece is perfectly cooked.
- Mess-Free: No need for baking sheets or frying pans—just toss the basket in the dishwasher when you’re done.
Ingredients You’ll Need
Here’s what you’ll need to get started:
- 3 medium sweet potatoes
- 1 tablespoon olive oil (optional but helps with crispiness)
- 1 teaspoon garlic powder
- 1 teaspoon smoked paprika
- ½ teaspoon salt (or to taste)
- ½ teaspoon black pepper
- Optional: A pinch of ground cinnamon for a festive touch
- Optional garnish: Fresh parsley or rosemary
Ingredient Notes
- Sweet potatoes: Look for firm, unblemished sweet potatoes. Smaller ones are easier to cut and cook faster.
- Olive oil: While you can skip the oil, a light coating helps seasonings stick and enhances crispiness.
- Seasonings: Garlic powder and smoked paprika add depth of flavor, but feel free to customize with your favorite spices.
Step-by-Step Instructions
1. Prepare the Sweet Potatoes
Start by thoroughly washing your sweet potatoes. If you prefer a rustic look and additional fiber, leave the skins on. Otherwise, peel them using a vegetable peeler.
Pro Tip: If you’re peeling, make sure to remove any dark spots or blemishes for the best results.
Once washed or peeled, cut the sweet potatoes into 1-inch cubes. Uniform sizes ensure even cooking, so take your time here.
2. Season the Cubes
Place the cubes in a large mixing bowl. Drizzle with olive oil, then sprinkle the garlic powder, smoked paprika, salt, and pepper over the top. Toss everything together until the sweet potatoes are evenly coated.
Customization Ideas:
- For a spicy kick, add cayenne pepper or chili powder.
- To bring out the natural sweetness, mix in a bit of brown sugar or nutmeg.
3. Preheat Your Air Fryer
Preheat your air fryer to 375°F (190°C). Preheating helps the sweet potatoes cook more evenly and ensures they start crisping up as soon as they hit the basket.
4. Arrange and Cook
Spread the sweet potato cubes in a single layer in the air fryer basket. Avoid overcrowding, as this can lead to steaming instead of crisping. If you’re cooking a large batch, work in smaller portions for the best results.
Set the timer for 12–15 minutes. Halfway through cooking, pause the air fryer and shake the basket to ensure even browning. If you like extra-crispy cubes, increase the temperature to 400°F (200°C) for the last 2 minutes.
Pro Tip: Check the cubes in the last few minutes of cooking to prevent burning. The exact cooking time can vary depending on the size of the cubes and the air fryer model.
5. Serve and Garnish
Once the sweet potato cubes are perfectly crispy, transfer them to a serving dish. Garnish with freshly chopped parsley or rosemary for a pop of color and added flavor. Serve warm and enjoy!
Tips for Perfect Crispy Air Fryer Sweet Potato Cubes
1. Cut Evenly
Uneven pieces can lead to some cubes being overcooked while others remain underdone. Use a sharp knife and take your time to create uniform cubes.
2. Don’t Overcrowd
Air fryers rely on hot air circulation. If the basket is too full, the cubes may steam instead of crisp up. Cook in batches if needed.
3. Preheat the Air Fryer
While it’s tempting to skip this step, preheating is crucial for achieving a crispy exterior.
4. Use Minimal Oil
Sweet potatoes don’t need much oil to crisp up. A light drizzle or spray is enough to do the trick.
Common Mistakes and How to Avoid Them
1. Soggy Cubes
Why it Happens: Overcrowding or skipping preheating. Solution: Cook in batches and always preheat your air fryer.
2. Uneven Cooking
Why it Happens: Inconsistent cube sizes or failing to shake the basket. Solution: Cut cubes uniformly and shake halfway through cooking.
3. Lack of Crispiness
Why it Happens: Too much oil or low cooking temperature. Solution: Use a minimal amount of oil and cook at a high enough temperature.

FAQs About Air Frying Sweet Potatoes
How long does it take for a sweet potato to go in an air fryer?
Sweet potato cubes usually take about 12–15 minutes to cook in an air fryer at 375°F (190°C). Larger pieces or whole sweet potatoes may take longer.
Why soak sweet potatoes before air frying?
Soaking sweet potatoes helps remove excess starch, which can result in crispier cubes. However, this step isn’t essential for sweet potatoes as it is for regular potatoes.
What happens if you don’t soak potatoes before air frying?
Skipping soaking may make the cubes slightly less crispy. That said, sweet potatoes naturally have less starch than regular potatoes, so soaking isn’t always necessary.
How long does it take for a potato to get soft in the air fryer?
To achieve a tender texture, sweet potato cubes need about 12–15 minutes in the air fryer. For larger pieces, the cooking time may increase to 30–40 minutes.
Creative Variations
1. Sweet and Spicy
Combine brown sugar, cinnamon, and cayenne pepper for a flavor-packed twist.
2. Herbed Delight
Toss the cubes with fresh rosemary, thyme, and a sprinkle of sea salt.
3. Cheesy Goodness
Add freshly grated Parmesan or feta cheese just before serving.
4. Smoky BBQ
Use a barbecue spice blend for a smoky, savory kick.
Storage and Reheating
If you have leftovers (though they rarely last!), here’s how to keep them fresh:
- Storage: Place the cooled cubes in an airtight container and refrigerate for up to 3 days.
- Reheating: Reheat in the air fryer at 375°F (190°C) for 3–5 minutes to restore crispiness.
