Peel, wash, and cut two large sweet potatoes into bite-sized cubes using a sharp knife on a cutting board.
Put the sweet potato cubes in a large bowl, cover them with water, and let them soak for 30 minutes to help remove excess starch and enhance crispiness. If you’re in a hurry, a quick soak for 5-10 minutes will do while you prepare the other ingredients. Once soaked, drain the water and pat the cubes dry with a paper towel.
In the same mixing bowl, toss the sweet potato cubes with 1-2 tablespoons of oil, a pinch of salt, and ½ teaspoon of cinnamon until evenly coated.
Preheat your air fryer to 375°F for 3-4 minutes (adjust according to your model). I used a Ninja Air Fryer with a basket.
Arrange the sweet potato cubes in a single layer in the air fryer basket or tray. Cook for 10 minutes, shaking the basket halfway through to ensure even cooking.
Once done, remove the cubes from the air fryer and sprinkle with fresh parsley, if desired, for extra flavor and presentation.
Enjoy these cubes as a snack or a side dish—they’re perfect any time of day!
Pair them with your favorite dipping sauce, like hummus or tzatziki, for more flavor and nutrition. They also make a great side dish with roasted chicken, turkey, or pork chops.
Not only are these air fryer sweet potato cubes crispy and delicious, but they’re also packed with nutrients like fiber, vitamin A, and potassium. Cooking them in an air fryer instead of deep-frying makes them a healthier alternative to traditional french fries or fried snacks. Next time you’re craving something crunchy, try these quick and easy sweet potato cubes!

Storage and Reheating Instructions
Allow the leftover sweet potato cubes to cool completely before transferring them to an airtight container. Store them in the refrigerator for up to 3-4 days.
To reheat, place the sweet potato cubes back in the air fryer at 375°F for 3-5 minutes or until heated through and crispy. Alternatively, you can reheat them in an oven to 375°F for about 10 minutes. For a quick option, use a microwave, though they may lose some crispiness.
