I perfected this recipe during my recent Whole30 journey. These babies have become an absolute must-have in our household. I’m going to be honest here, before I discovered this game-changing cooking method, I was totally disappointed with how my sweet potatoes turned out in the air fryer. So let me share my secret with you and turn those underwhelming potatoes into mouth watering perfection!

Some recipes have secret ingredients, this recipe has a secret step! The extra step is truly a game changer! You can tell just be looking at them that they are different from other photos of air fryer sweet potato cubes.

Sweet potatoes are so nutritious and a great source of fiber, Vitamin A, Vitamin C, Maganese and potassium which makes them the perfect carb to add to so many delightful dishes!

One of my very favorite ways to enjoy sweet potatoes is by roasting them, like my super popular roasted sweet potatoes with bacon and parmesan recipe. I’m a huge fan of roasting literally ANY veggie. Roasting brings out the natural sweetness in them while caramelizing the outside for ultimate flavor and texture. I always keep my air fryer on stand-by for quick side dishes. It’s so much more convenient(and quick!) than heating up the oven.

Ingredients you need

The list of ingredients is short and sweet. You probably have it all (except for the sweet potatoes) on hand most of the time. Plus, you can really play with spices to create a range of flavors depending on your mood and/or meal, so feel free to swap some of the below to use your favorite dried spices (or scroll down a bit cause I’ll include a few of my favorite variations).

  • Sweet Potatoes – There are actually A LOT of different varieties of sweet potatoes. I can usually only get 2-3 different types in my neck of the woods which are Red Garnet, Jewel, and Beauregard. For this recipe, I’ve only made it with these varieties. Finding white sweet potatoes around here is next to impossible.
  • Olive Oil– or avocado oil.
  • Smoked Paprika 
  • Salt and Pepper
  • Garlic Powder
  • Cumin

How to cut Sweet Potato Cubes

Scrub and Rub – Give those sweet potatoes a nice wash and dry to remove any dirt or residue.

Peel’m – Grab your trusty vegetable peeler and peel off the skin from those spuds.

Slice ‘n Dice – Cut the sweet potato into about 1/2-inch rounds, then cut again into either fourths or into sixths depending. on how large the sweet potato is around.

How to make Air Fryer Sweet Potato Cubes

Okay so, here’s the “secret step” I mentioned earlier. It’s going to add a few minutes to your total time making these, but it’s 1,000% percent worth it. This is what sets them apart from every single air fryer roasted sweet potato recipe i’ve ever found on the internet.

Add your sweet potato cubes to a microwave safe bowl and then add about 1/4 cup water to the bowl. Place in the microwave and cook for about 2 minutes then stir real quick then continue to cook for about 2 minutes. The potatoes should be fork tender, not mushy.

Note: If you don’t love using the microwave/don’t have one you can also boil the potatoes in water on the stove top for about 5-6 minutes until fork tender.

This method is different from soaking potatoes like you would white potatoes so don’t do that thinking you will get the same results.

When the potatoes are done cooking remove bowl (careful it might be hot!) from the microwave and add spices.

You can get creative and do any spices you’d like. I’m gonna share my favorite kind of “all purpose” mix with you that goes great with just about anything!

Add avocado (or olive) oil, kosher salt, cumin, garlic powder, smoked paprika, and pepper. If there’s a little water still in the bowl leftover from cooking, no worries! It actually almost helps the spices and oil coat the potatoes even better!

While this recipe is SUPER easy, there are a couple steps you can’t slack on, okay? The precook is a MUST, and stirring (practically beating them) roughly with a fork is also non negotiable.

I learned this method of cooking potatoes actually years ago from Bobby Flay, but this was only for white potatoes. For some reason, I always thought sweet potatoes wouldn’t work this way. Wow, I was so wrong.

Now, take a fork and stir the sweet potato cubes aggressively for a good minute or two. Make sure the seasoning is distributed well. The fork is used because it creates small knicks in the peices of potato each time you hit one while stirring. This helps to create tiny potato pieces that kind of coat the other potatoes. It’s magic, I tell ya! Magic!

Just like an oven, you’ll want to preheat your air fryer.

After preheating add sweet potato chunks to the air fryer basket, spread them out in a single layer so they don’t get too crowded. More air circulation= evenly cooked + more crispy texture.

I cook these at 400 degrees for about 10 minutes total and shake the basket 1-2 times during the total cooking time. If you want them a little extra crispy you can add a couple of minutes.

If you want to double the recipe, make sure to do two separate batches so the basket isn’t over crowded.

I have been using this recipe for sweet potato cubes in so many different things. Here are a few of my favorite ideas that I think you’ll love too!
