Using your hands, toss the cubes in the oil and spice mixture, ensuring that they are well coated, then spread them in a single layer in your air fryer basket, don’t overcrowd them, or they’ll become soggy.

Recipe notes and expert tips

  • Preheat
    We pre-heat our air fryer, but if you have an oven-style basket-type air fryer, then you probably won’t need to. 
  • Make them sweet
    If you prefer sweet rather than savory sweet potatoes, then use brown sugar and cinnamon and toss the potato cubes in this.
  • Overcrowding
    Be careful not to overcrowd the sweet potato cubes in the air fryer basket, they won’t crisp up, and they’ll become soggy.
  • Watch closely
    Every air fryer cooks differently; different brands and capacities can mean that your food will need a longer or shorter cooking time, so keep a close eye on them.

How to store leftover sweet potato cubes

Store any leftovers in the fridge in an airtight container for up to 3 days and in the freezer for up to 3 months.

What to serve with air fryer sweet potato cubes

You can serve easy air fryer sweet potato cubes as a side dish along with mains, mushroom wellington, spinach, and ricotta lasagna, or even an air fryer vegan ham.

Or you can serve them as a snack along with your favorite dipping sauce; sweet chili sauce, BBQ sauce, maple syrup ketchup, or delicious garlic aioli.

Recipe variations

Mix up the seasonings; we’ve opted for savory sweet potatoes with a savory spice blend, but if you’re in the mood for a sweet version, try them with brown sugar and maple syrup.

Spice them up by adding cayenne pepper, red chili flakes, or chili powder.

Do I need to soak sweet potatoes?

No, you don’t need to soak sweet potatoes; they have as much starch as white potatoes, so they crisp up nicely in the air fryer.

Can I use frozen sweet potato chunks?

Yep, you certainly can!

You can cook from frozen, they crisp up really well, and most frozen sweet potatoes are peeled and cubed – so it makes it even easier!
