How to Make Air Fryer Crispy Sweet Potato Cinnamon Cubes

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 1/2 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!

Why Soak Sweet Potatoes Before Air Frying?

If you love crispy, golden sweet potato cubes, soaking them before air frying can make a big difference. Though it might seem like an extra step, this simple technique helps remove excess starch, resulting in a crispier texture and better overall taste when cooked.

Why Are My Air Fried Sweet Potatoes Not Crispy?

Air fryers are great for making crispy, flavorful dishes with little oil, but achieving that perfect crunch with sweet potatoes can sometimes be tricky. Here are some common reasons:

Not Preheating – Preheating your air fryer is essential for even heat distribution, ensuring your sweet potatoes cook evenly and become crispy. Skipping this step can result in soggy sweet potatoes.
Improper Seasoning—Seasoning is key for both flavor and crispiness. To help your sweet potatoes crisp up in the air fryer, toss them with olive oil or lightly spray them before adding any seasonings.
Overcrowding—To avoid overcrowding the air fryer basket or tray, arrange the sweet potato cubes in a single layer with enough space between each piece to allow air to circulate and create the perfect crispy texture.

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.

What to Serve with Air Fryer Sweet Potato Cubes

Air fryer sweet potato cubes pair wonderfully with a variety of dishes. Here are some ideas to complement them:

Protein-Rich Dishes – Serve with grilled chicken, roasted turkey, or pork chops for a balanced meal.
Dipping Sauces – Pair with hummus, tzatziki, or a spicy yogurt dip for added flavor.
Grains: Serve alongside quinoa, brown rice, or couscous for a hearty side dish or light main meal.
Salads—Toss them into a fresh green salad or serve them as a topping for a hearty salad with leafy greens, nuts, and feta.
Veggies – Pair with roasted or sautéed vegetables like broccoli, spinach, or Brussels sprouts for a nutritious, vegetable-packed plate.

Wrapping Up

These air fryer sweet potato cubes are a delightful blend of taste and nutrition, making them a guilt-free indulgence. With minimal effort and maximum flavor, they’re perfect for any time of the day. Whether you enjoy them as a perfect side dish or a healthy snack, they’re a testament to how simple ingredients can create extraordinary flavors.
