What do you need?

The ingredients for this sweet potato cubes recipe.

Sweet potatoes

Choose any variety of sweet potato. The type with smooth skin and orange flesh (sometimes called ‘yams’) are a good choice for a side dish to brighten up you table.

Oil

I use light olive oil for this recipe, but you can substitute any cooking oil you normally use with your air fryer. Vegetable oil, corn oil, or avocado oil are all good options.

For a healthier version of this recipe, you can use an olive oil spray and just give the cubes a couple of spritzes of oil.

Seasoning

The recipe below uses a blend of rosemary, garlic powder, salt and black pepper.

Feel free to switch out the seasonings for any other flavors you like. Paprika, smoked paprika, or cayenne pepper are all good options. Or try adding a drizzle of honey.

Parmesan cheese

Parmesan cheese is optional, but is delicious melted over the sweet potatoes once they are almost finished cooking.

How to cook sweet potato cubes in the air fryer

This recipe is very simple to make, there are just a few key steps to getting it just right:

  1. Scrub the sweet potatoes and peel if desired (leave the skin on if you like).
  2. Cut the sweet potatoes into large chunks around 1-inch across. This helps to prevent them being overcooked and becoming mushy. Try to cut them all roughly the same size so they cook in the same amount of time.
  3. Toss the sweet potato chunks with oil and seasoning.
  4. Don’t crowd the basket. If you want crispy sweet potatoes you need to leave plenty of room around the cubes for the air to circulate. If the basket is too crowded they will steam and won’t crisp up.
  5. Air fry HOT! 380°F/ 190°C is a good temperature to cook these sweet postatoes fast so they cook through quickly without drying out.

Storing and reheating

Refrigerate any leftover sweet potatoes in an airtight container in the fridge for up to 5 days.

You can also freeze the leftovers in an airtight freezer-safe container for up to 3 months. Allow them to thaw overnight in the fridge before reheating.

You can reheat sweet potatoes in the air fryer at 360°F/ 180°C for 5 minutes.

Ingredients

  • 1/2 tablespoon olive oil
  • 1/2 tablespoon minced fresh rosemary
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon salt

  2. Add the sweet potato cubes to a bowl, drizzle with olive oil, add the seasoning and toss to coat thoroughly.
  3. Place sweet potato cubes in air fryer basket [Note 1]. Place them in a single layer if possible.
    Air fry for 15-20 minutes tossing the basket every 5 minutes to redistribute the cubes [Note 2].
  4. The sweet potatoes will be tender and crisp at the edges when they are done. If required, air fry for additional 5-minute intervals until they are cooked to your liking.
