🌟 Why this recipe works
Air fryer sweet potatoes are the best way to eat sweet potatoes. They taste delicious no matter which way you prepare them, but cooking them in the air fryer is quicker and gives the cubed sweet potatoes a beautiful crunchy texture.
With 1 pound of sweet potato, you can make enough sweet potato chunks to feed a small family or devour them with your hubby along with a dipping sauce for movie night and ditch the popcorn.
The flavor is a simple seasoning of salt, which is all you need to draw out the flavor from the sweet potatoes. Although, they do take on board many seasonings from savory to sweet to give them additional flavors. See the variations section for the best seasonings to use with sweet potato chunks.
As long as you have an air fryer, you can make delicious snacks/side dishes like crispy mushrooms, garlic bread in an airfryer, or shrimp. An air fryer cuts cooking times in half and uses much less oil to achieve super crispy results, making them good value for your money for home cooks.
🍽 Key Ingredients
You ONLY need olive oil and salt for air fryer sweet potato cubes.
Sweet potatoes: When choosing your sweet potatoes, make sure to choose the long narrow ones to make it easier to cube them into the same size.
Oil: Olive oil gives the air fryer sweet potatoes extra flavor and crunch.
Oil - You can substitute regular olive for extra virgin olive oil without changing the flavor. You could also use canola or avocado oil for a lighter option and still get crispy sweet potato cubes.

💭 Cooking Tips
Don't overcrowd the sweet potato chunks.
If you want the crispiest potatoes, make sure to layer them in a single layer in the air fryer basket so that the hot air can circulate freely.
Sweet potatoes tend to go a bit limp as they cool, so it's best to eat them as soon as they're ready for the best crunchy texture.
Shake the basket
Another essential tip to get even browning on those delicious potatoes is shaking the air fryer basket during cooking to ensure they don't burn.
To avoid uneven cooked sweet potatoes, it's important to cut them the same size (or as close as possible), as larger chunks will take longer to cook.
📖 Recipe Variations
Air fryer sweet potato cubes taste even better when mixed with savory or sweet spices. These are some of my go-to seasonings to combine with sweet potatoes.
Maple syrup, half a teaspoon cinnamon, 1 tablespoon of brown sugar
The combination of these 3 ingredients is heavenly when tossed with crispy air fryer sweet potato cubes. Mix the brown sugar with the cinnamon, and toss the hot sweet potato cubes in the mixture. Drizzle with maple syrup, and you have a delicious treat!
¼ teaspoon cayenne pepper, ¼ teaspoon salt, 1 teaspoon chipotle chili powder, 1 teaspoon smoked paprika, 1 teaspoon Cajun mix
This mixture is rather hot on the tongue, but the sweetness from the sweet potatoes helps cool it down. Combine the ingredients in a bowl and sprinkle over them when cooked.
You can also sprinkle curry powder over them to taste indian flavor.
½ teaspoon garlic powder, onion powder, cumin, turmeric, 1 teaspoon smoked paprika, ¼ teaspoon black pepper & salt
Turmeric is a magic seasoning with many healthy properties, and it blends well with sweet potatoes. When combined with the other seasonings, this savory blend brings out all the natural goodness of the sweet potatoes.
🥗 What to serve with

🙋Frequently Asked Questions
Do you need to soak sweet potatoes in water before air frying?
Sweet potatoes don't have as much starch, so they don't need to soak, unlike standard potatoes that require soaking or boiling to remove the starch before cooking them.
Why are my air fryer sweet potatoes soggy?
One of the main causes of soggy sweet potato fries or cubes is an overloaded fryer basket that creates moisture between the potatoes and air fry.
Moisture can also come from the potatoes or the air fryer, so make sure to clean the machine and pat dry the sweet potatoes before air frying.

🧊 Storing and ♨️Reheating
I love air fryer sweet potato cubes! Whether they're just cooked, cold leftovers, or reheated to a crisp again - they're delicious and store well.
Fridge: Transfer any leftover sweet potatoes to an airtight container and place them in the fridge for up to 4 days.
Freezer: Place leftovers on a baking sheet lined with parchment paper and place it in the freezer till frozen, then transfer the frozen sweet potato cubes to freezer bags or an airtight container. Freeze for a maximum of 4 months
Reheating: Reheat any leftover sweet potato cubes in the air fryer at 400 degrees Fahrenheit for 4-5 minutes and 7-8 minutes for frozen. You don't need to defrost them before air frying - place them in the basket in a single layer, and they will crisp up nicely.
