Air Fryer Sweet Potato Cubes

Sometimes side dishes are the star of the meal, and these no-fuss air fryer sweet potato cubes are not only ridiculously easy, but they are flavor packed, nutritious, and loved by even the pickiest of eaters. Roasting sweet potatoes brings out their natural sweetness, making them the perfect vegetable for roasting.

Sweet potatoes pack a punch when it comes to nutrition. They are known for their beta-carotene (which converts into vitamin A and is great for the immune system), are a good source of vitamin C, potassium, antioxidants, and fiber. You can also try them in my sweet potato crust quiche.

Why use an air fryer? Using an air fryer is quicker and requires less energy than the oven. Air fryers preheat in no time and due to the technology, they cook the food quicker as well.

Ingredient Notes

• Sweet Potatoes - You can really use any variation for these air fryer sweet potato cubes. See the below section for recommendations.

Which Type of Sweet Potatoes Are Best for Air Frying?

You'll likely encounter a few different kinds of sweet potatoes when you are at the grocery store. First off, you really can't go wrong, and any kind will work great in this air fryer recipe, but they each have their differences.

Most commonly you'll see either Beauregards or jewel sweet potatoes. These both have a firm flesh and sweet flavor profile and are ideal for roasting. If you see a bin labeled "sweet potatoes" they are most likely Beauregards.

Beauregards have purplish-red skin and a deep orange interior and are typically pretty large. Jewel sweet potatoes are a little less sweet, but have a similar interior and will roast up the same.

You may also find Garnet varieties, which have a darker red-ish/purple flesh. They are less sweet and have a little more of a "watery" texture. These are not the best for roasting in the air fryer, but if that's all you have, they will definitely still work.

And lastly, Hannah (aka white sweet potatoes) are more dense and dry than a Beauregard or jewel variety. They are slightly less sweet, but roast up beautifully. I actually really like using these from time to time. Just know they are more similar to a Yukon gold potato.

How to Make

Step 1: Peel and slice sweet potatoes into ½" cubes. Try to keep them all roughly the same size so they cook up evenly.

Step 2: Add sweet potato cubes to a mixing bowl and drizzle with extra-virgin olive oil

Step 3: Add paprika, salt, garlic powder, and onion powder.

Step 4: Mix until sweet potato cubes are evenly coated in oil and seasonings.

Step 5: Preheat air fryer to 390F. Add sweet potato cubes to air fryer basket, trying not to overlap too much. It's okay if they are touching as they will shrink as they cook.

Step 6: Air fry for 12-14 minutes, shaking basket halfway through. Sweet potatoes are done when they can easily be pierced with a fork and are browned to your liking.

These air fryer sweet potato cubes are best served right away. Enjoy!

Expert Tips & Notes

Roasting in the oven: No air fryer? No problem! Follow the same prep steps and then place on a large lined baking sheet and bake at 420-degrees F for 25 minutes, stirring halfway through. Cook longer if you'd like them extra browned.

Make into sweet potato fries or wedges: Not digging the sweet potato cubes? You can follow the same directions, but cut your sweet potatoes into evenly shaped fries or wedges. You may need to increase cook time if making wedges.

Recipe FAQs

Storing and Reheating

Storing: Leftovers should be stored in the fridge in an airtight container and will stay fresh for up to 5 days. Just know they will lose their crispiness once stored.

Freezing: Air fryer sweet potatoes can also be frozen for up to 3 months. Make sure to freeze in a freezer safe container. I love Stasher bags for freezing.

Reheating: You can reheat in the air fryer or the microwave. Air fry at 400F for 3-5 minutes or throw in the microwave for about a minute (total time will vary depending on how many you are reheating).
