How to cut sweet potatoes into cubes
Cooking frozen sweet potatoes in an air fryer is a quick and easy way to prepare a delicious and healthy side dish. The air fryer cooks them evenly throughout, resulting in a perfect combination of sweetness and crunch.
To cut sweet potatoes into cubes, start by creating a flat bottom so that they can sit safely on your cutting board. You can achieve this by cutting the potato in half crosswise with a sharp knife, such as a chef's knife. This will provide a stable base for further slicing.
Next, slice each half lengthwise into three or four planks, depending on your desired cube size. Lay each plank flat-side down on the cutting board and cut lengthwise again into strips, creating skinny planks.
Finally, chop the strips into half-inch pieces to form uniform sweet potato cubes. If you prefer thicker or thinner cubes, you can adjust the width of your strips accordingly.
Alternatively, you can use a vegetable peeler to peel the sweet potatoes before cutting them into cubes. This method may be safer and more comfortable for some cooks.

How to season sweet potatoes
Cooking frozen sweet potatoes in an air fryer is easy and convenient. You can cook them straight from frozen, without thawing, to avoid sogginess. The cooking time will depend on the size of your sweet potato cubes, but it should take anywhere from 12 to 16 minutes or more at 400°F.
Now, for the seasoning. You can use a variety of seasonings to add flavor to your sweet potatoes. Here are some ideas:
- Olive oil, salt, and pepper: This classic combination provides moisture, flavor, and helps create a crispy exterior. Use just enough oil to coat the potatoes and allow the seasonings to stick.
- Avocado oil or canola oil: These oils have a high smoke point, making them suitable for air frying.
- Curry powder, turmeric, cumin, and garam masala: These spices add a savory, earthy flavor to your sweet potatoes.
- Chili powder, cumin, cinnamon, or pumpkin spice: A calorie-free option that adds a kick of spice or warmth to your potatoes.

How to cook sweet potatoes in an air fryer
Cooking sweet potatoes in an air fryer is a quick and easy way to prepare a delicious and healthy side dish. The air fryer cooks them evenly throughout, resulting in a perfectly crisp exterior and a tender interior.
Ingredients:
- Frozen sweet potato cubes
- Olive oil
- Salt
- Pepper
- Seasonings of your choice (e.g. za'atar, garlic powder, paprika, or dried parsley)
Instructions:
First, preheat your air fryer to 400°F (205°C) for about 4 minutes to remove any frost from the frozen sweet potatoes. This step is optional but helps to ensure the potatoes don't stick to the basket.
Next, pour the frozen sweet potato cubes into the air fryer basket. If you're using fresh sweet potatoes, peel and cut them into uniform cubes of about 1/2-inch in size. Add olive oil, salt, and any desired seasonings to taste. You can also add other ingredients like bacon and Parmesan cheese for extra flavor. Toss the potatoes until each piece is well-coated with oil and seasoning.
Return the basket to the air fryer and cook for 8-15 minutes, depending on the size of your sweet potato cubes. For smaller cubes, check after 8-10 minutes. For larger cubes, they may take up to 15-16 minutes or more. To ensure even browning, shake the basket halfway through the cooking process and rotate the potatoes.
When the potatoes are golden brown and crispy, they are ready to be served! Enjoy them as a side dish, snack, or topping for rice bowls, salads, or tacos.
Tips:
- If you prefer to season halfway through cooking, you can first air fry the potatoes for 5 minutes, then toss them with the seasonings in a mixing bowl before returning them to the air fryer.
- For mess-free cooking, use air fryer silicone mats or parchment paper.
- To reheat, place the sweet potatoes in the air fryer at 350-375°F for 3-5 minutes.
