Air Fryer Crispy Sweet Potato Cubes

These air fryer crispy sweet potato cubes are perfectly seasoned! Making them a quick and easy side dish for Jerk Chicken or breakfast potatoes. Whole30 and Paleo too.

Sweet potatoes have to be one of my favorite root vegetables! Sweet, healthy, and filling. They are a lifesaver if you are on a Whole30 round. Looking for a healthy breakfast option? Try my Sweet Potato Hash with Bacon! It's Whole30 and Paleo-approved.

Roasted sweet potatoes are the best! Cut them into cubes, fries, or even wedges. Roasting at a high temp brings out the natural sugars. Can you say YUM!

To achieve the ultimate crispy sweet potato cube, we will be using the air fryer. It will allow us to roast sweet potatoes quickly.

We also use the air fryer to cook vegetables like butternut squash. You can see this in our Beetroot and Butternut Squash Salad recipe.

Serve these potatoes with my Air Fryer Jerk Chicken, Mango Salsa, and Coconut Cauliflower Rice.

How to make this recipe

Making air fryer crispy sweet potato cubes is so easy, here's how to make it:

Step 1: Peel sweet potatoes and square off the ends.

Step 2: Cut into 1- inch planks. I like to square off one side of the sweet potatoes, so it doesn't roll on me.

Step 3: Cube sweet potatoes into ½-inch pieces. A shape 8-inch chef knife works the best.

Step 4: In a large bowl toss potatoes, seasonings, and oil.

Step 5: Preheat the air fryer to 400 degrees. Play sweet potatoes cubes in a single layer, spacing them out. You will need to cook them in batches to avoid overcrowding the basket.

Step 6: Cook for 12 minutes. Shake the basket at the halfway mark (6 minutes). Sweet potatoes should have a crispy exterior and a soft interior.
