Key Ingredient Notes

  • Sweet Potatoes: This recipe uses fresh sweet potatoes. I will also include some notes on how to use frozen sweet potatoes in the post below.
  • Olive Oil: Use from 1 to 3 tablespoons of olive oil depending on how soft of a roast you like. I usually use about 2 tablespoons. You could also use avocado oil or butter.
  • Salt: Add salt to your taste. This helps bring out the flavor in the sweet potato.
  • Brown Sugar: This adds a nice sweetness and compliments the cinnamon well. You can also use honey in place or in addition to the brown sugar for extra caramelization.
  • Nutmeg: Just a little add another layer of flavor without overpowering it. If you don’t like it just omit it.

If you want a savory option see the recipe notes, the variation section, or use your favorite seasonings.

How to Make Air Fryer Sweet Potato Cubes

Be sure to see the recipe card below for exact ingredients and full recipe instructions!

Step 1 | Prep, Cut, and Toss Sweet Potatoes

Wash sweet potatoes thoroughly and then place them on a cutting board and cut them into even-sized cubes. You can leave peels on or peel them whichever way you prefer them.

I like to give the sweet potato chunks another rinse and then pour them onto a paper towel and pat dry with paper towels. The drier they are the more of a crisp roast you will get.

Place in a large bowl and toss with olive oil then add remaining ingredients and toss to coat.

Step 2 | Preheat Air Fryer and Cook

Preheat the air fryer according to the make of your air fryer for about 5 minutes.

Place in the air fryer basket for about 15 to 20 minutes, tossing halfway through cook time. The thickness and size of the air fryer will determine cook time.

Test the largest potato with a fork to be sure it is tender.

  • Remember each air fryer cooks differently. The thickness of the potato will also affect the cooking time. Usually, about 15 minutes will be sufficient, but up to 20 minutes can be needed to achieve the desired doneness.
  • Cutting potatoes at the same thickness will ensure even cooking.
  • Place potatoes in a single layer with some space in between to allow the hot air to circulate which will result in perfect crispy sweet potato cubes.

Frequently Asked Questions

What are the best sweet potatoes to use?

There are many varieties of sweet potatoes and they do not all have the same texture and taste. I like using the orange-skinned sweet potatoes (like Garnet or Jewel) as they are most commonly found and have a really sweet creamy texture. You can also find purple, white, or Japanese sweet potatoes. The best way to know is to give them a try.

How many sweet potatoes are in a pound?

2 large or 3 medium whole sweet potatoes will make around a pound of sweet potatoes. This is about 3 ½ to 4 cups of cubes of potatoes. A kitchen scale is also useful when wanting to determine the exact weight.

Can you use frozen sweet potatoes?

Yes. You can use this method to cook frozen sweet potatoes in the air fryer. To do this you will use them straight out of the freezer (do not thaw them). These are often diced a little smaller so you will need about 2 to 3 cups of frozen sweet potatoes and the cooking time and instructions will be about the same (15 minutes) since they are frozen. You may find you need to add a touch more oil to aid in crisping.

Can you eat the skin of the sweet potato?

Yes. It is safe to eat a cooked or raw sweet potato. Since they are grown in the ground you will want to wash them well. I like to scrub them lightly with a brush and pull off any roots if attached. An extra benefit is they are packed with antioxidants so leaving them on is a plus. It usually comes down to a preference of texture, so eat them the way you like them – skin on or off.

Variations and Substitutions:

  • Drizzle with Honey or Maple Syrup: For extra sweetness and a beautiful sheen.
  • Drizzle with warmed up marshmallow fluff for a real decadent treat.
  • Sprinkle with pecans or walnuts for the last couple of minutes while cooking for a nutty addition.
  • For a savory option use  ¼ teaspoon each of black pepperpaprikacayenne peppergarlic powder, and cumin in place of the cinnamon, nutmeg, and brown sugar.
  • Toss with olive oil or butter, salt, pepper, garlic powder (or fresh minced garlic), and add diced bacon and air fry. This is also really delicious with a little bit of maple syrup too.
  • Thyme and rosemary are also delicious herbs on roasted sweet potatoes.
  • For a Mexican spin try a little chili powder or taco seasoning, sea salt, lime juice, and garnish with cilantro. Or use a chili lime seasoning like Tajin

Storage, Make Ahead and Reheating Instructions

Make Ahead: Prep the night before, cover, and refrigerate until ready to cook.

Store leftovers: You can store air-fried sweet potatoes in an airtight container or zip bag and store them in the refrigerator for up to 3-4 days.

Reheat: Reheat them in the air fryer at 375°F for about 5 minutes or until heated through.

To reheat individual servings in the microwave, place desired amount on a microwave-safe dish and reheat. Add 30-second intervals until heated to your liking. The microwave will produce a softer potato.

    I was never a big fan of sweet potatoes but as I have gotten older I have started to love them. These are so delicious, like healthy candy!! I even made a batch with some paprika and cayenne pepper and even my son ate them!
