Why Choose the Air Fryer for Sweet Potatoes?
While sweet potatoes are delicious in many forms, the air fryer elevates them to a new level. Here’s why it’s the optimal cooking method for perfectly crispy cubes:
- Unmatched Crispiness: The powerful circulating hot air creates an incredibly crispy exterior on each cube, mimicking deep-frying without the excess oil.
- Reduced Oil: You’ll use significantly less oil compared to traditional roasting or frying, resulting in a lighter, healthier dish.
- Faster Cooking: The concentrated heat cooks sweet potatoes much quicker than a conventional oven, making it ideal for busy schedules.
- Even Cooking: When arranged in a single layer and shaken occasionally, the air fryer ensures every side of every cube gets perfectly cooked and browned.
- Energy Efficient: Heating a smaller appliance like an air fryer uses less energy than preheating and running a large oven.
KEY INGREDIENTS FOR PERFECT AIR FRYER SWEET POTATO CUBES
This simple recipe calls for just four core ingredients, but don’t let the short list fool you – they combine to create an incredible flavor. Here’s a closer look at what you’ll need to make these mouth-watering **sweet potato chunks**:
- Sweet Potatoes: You’ll need two to three medium sweet potatoes. When selecting them, look for ones that are bright in color, firm to the touch, and have smooth, unblemished skin. Avoid any with soft spots or sprouts. While true sweet potatoes are ideal, if you’re in a pinch, garnet or jewel yams can be a suitable substitute, offering a similar sweetness and texture once cooked. Remember, consistent sizing when cubing is key for even cooking!
- Olive Oil: For air frying, **extra light olive oil** is highly recommended due to its high smoke point, which helps prevent burning and ensures a cleaner flavor. Alternatively, **avocado oil** or grapeseed oil are excellent choices as they also have high smoke points and neutral flavors that won’t overpower the sweet potatoes. A good coating of oil is essential for that desired crispiness.
- Black Pepper: Freshly ground black pepper adds a wonderful fragrant punch and a subtle warmth that beautifully contrasts the natural sweetness of the potatoes. For the most vibrant flavor, we always recommend using freshly ground pepper over pre-ground varieties.
- Garlic Powder: Finely ground garlic powder infuses the sweet potatoes with a savory depth. If you prefer, you can use garlic granules, though you might need a slightly smaller amount as they can be more potent. Ensure it’s not garlic salt, unless you plan to adjust other salt additions.
Optional Flavor Boosters:
While the basic seasoning is fantastic, feel free to experiment! Here are a few ideas:
- Salt: A pinch of sea salt or kosher salt really brings out the natural flavors of the sweet potato. Add it to taste.
- Paprika: For a touch of warmth and color. Smoked paprika adds a lovely smoky note.
- Onion Powder: Complements the garlic powder perfectly for a more rounded savory profile.
- Cinnamon & Nutmeg: For a sweeter, fall-inspired flavor, especially if you plan to serve them as a dessert-like side.
- Cayenne Pepper or Chili Powder: If you enjoy a bit of heat, a dash of either can add a delightful kick.
HOW TO MAKE PERFECTLY CRISPY AIR FRYER SWEET POTATO CUBES
Creating these delectable **air fryer sweet potato cubes** is incredibly straightforward. Follow these simple steps for a consistently delicious result:
STEP 1: PREP THE SWEET POTATOES. Rinse the sweet potatoes thoroughly under cold running water to remove any dirt. Pat them completely dry with a clean towel – this helps the oil and seasonings adhere better and promotes crispiness. Next, remove the skin using a sharp vegetable peeler. While some prefer leaving the skin on for extra fiber and rustic appeal, peeling ensures a more uniform texture and allows the seasonings to really penetrate the flesh.
STEP 2: CUBE THE POTATOES. Using a sharp chef’s knife, carefully cut the skinned potatoes into uniform 1-inch cubes. Consistency in size is paramount here; it ensures that all pieces cook at the same rate, preventing some from being undercooked while others are burnt. Aim for pieces roughly the same size as dice.
STEP 3: SEASON THE CUBES. In a medium mixing bowl, combine the uniformly cubed sweet potatoes with the chosen olive oil (or alternative high smoke point oil), garlic powder, and black pepper. Use a spatula or your hands (wearing gloves if preferred) to thoroughly mix and evenly coat every single potato cube. A good coating ensures maximum flavor and optimal crispiness. Don’t be shy about ensuring every surface is touched by oil and spice.
STEP 4: PREHEAT YOUR AIR FRYER. Preheat your air fryer to 400º F (200º C). This crucial step ensures that the sweet potatoes begin cooking immediately upon entering the hot basket, leading to a much crispier result. If your model doesn’t have a specific preheat setting, simply run it empty at 400º F for 3-5 minutes.
STEP 5: ARRANGE IN THE BASKET. Once preheated, carefully add the seasoned sweet potato cubes to the prepared air fryer basket. It’s vital to arrange them in a **single layer** without overlapping. Crowding the basket will steam the potatoes rather than air fry them, preventing them from achieving that desirable golden-brown crispiness. If necessary, cook in multiple batches.
STEP 6: AIR FRY TO PERFECTION. Air fry the potatoes at 400º F (200º C) for 15-20 minutes. Be sure to open the basket and give it a good shake halfway through the cooking time (around the 7-10 minute mark). This ensures all sides get even exposure to the hot air, leading to uniformly crispy, golden-brown results. Continue cooking until they are tender when pierced with a fork and beautifully caramelized on the outside.
EXPERT TIPS FOR THE CRISPIEST AIR FRYER SWEET POTATO CUBES
Achieving perfectly crispy and tender sweet potato cubes in your air fryer is simple with these key tips:
- Preheat the Air Fryer: This step is non-negotiable for superior results. Just like oven baking, preheating your air fryer ensures that the sweet potatoes hit a high temperature immediately, initiating that beautiful caramelization and crisping process from the get-go. If your air fryer doesn’t have a dedicated preheat function, simply run it empty at 400º F (200º C) for 3-5 minutes before adding your seasoned potatoes.
- Don’t Overcrowd the Basket: This is arguably the most crucial tip for any air fryer recipe! For sweet potato cubes to get truly crispy, the hot air needs to circulate freely around each individual piece. If you pile them up or overlap them, they will steam instead of fry, resulting in soggy rather than crispy potatoes. If you have a larger batch, cook the sweet potatoes in several batches, ensuring a single layer each time. Patience here pays off immensely.
- Cut Uniform Cubes: To ensure even cooking, strive to cut your sweet potatoes into roughly 1-inch cubes of a consistent size. Irregularly sized pieces will lead to some being perfectly cooked while others are still hard or, conversely, overcooked. A sharp chef’s knife and a steady hand will make this much easier.
- Shake the Basket (or Flip) Halfway: To guarantee uniform crispiness and browning on all sides, remember to open the air fryer basket and give the sweet potato cubes a good shake or flip them with tongs halfway through the cooking time. This redistributes the potatoes and exposes new surfaces to the direct hot air. It’s also a great opportunity to check on their progress and adjust cooking time if needed.
- Apply Oil Evenly: A light, even coating of oil is essential for that beautiful golden crisp. Ensure every cube is well-coated with your chosen high-smoke-point oil (like extra light olive oil or avocado oil) before placing them in the air fryer. This helps with browning and prevents sticking.
- Adjust Temperature and Cooking Time as Needed: Air fryer models can vary significantly in their power and efficiency. This recipe was developed using a Cosori Air Fryer. If you’re using a different brand or model, you may need to adjust the cooking time by a few minutes, either adding or subtracting, to achieve your desired level of tenderness and crispiness. Always keep an eye on your potatoes, especially during the first few times you make this recipe.
DELICIOUS VARIATIONS FOR YOUR AIR FRYER SWEET POTATO CUBES
One of the best things about this recipe is how easily you can customize it to fit any meal or craving. Here are some fantastic flavor variations to try with your **air fryer sweet potato cubes**:
- Savory Sweet Potatoes: For a more robust, earthy flavor profile, enhance the basic seasoning with a sprinkle of **chili powder**, **onion powder**, and **paprika**. You can also add a pinch of dried thyme or rosemary for an aromatic touch, making them an excellent accompaniment to roasted meats or a hearty stew.
- Sweet & Warming: To lean into the natural sweetness of the potatoes, try adding a tablespoon of **maple syrup** or honey along with a generous dusting of **ground cinnamon** and a pinch of nutmeg or allspice before air frying. This creates a dessert-like side that’s perfect for holiday meals or breakfast.
- Spicy Kick: If you love a little heat, sprinkle your seasoned sweet potatoes with a pinch of **cayenne pepper** or a dash of hot sauce before cooking. A little extra pinch of salt can also help balance the heat and bring out more flavor.
- Herby Freshness: After cooking, toss the warm sweet potato cubes with finely chopped fresh herbs like parsley, cilantro, or chives for a burst of fresh flavor and vibrant color.
- Cheesy Indulgence: In the last 2-3 minutes of air frying, sprinkle a little grated Parmesan cheese over the cubes. The cheese will melt and become wonderfully crispy, adding a salty, umami layer.
FREQUENTLY ASKED QUESTIONS ABOUT AIR FRYER SWEET POTATO CUBES
HOW DO I STORE LEFTOVERS?
To keep your **air fried sweet potato cubes** fresh, allow them to cool completely to room temperature before transferring them to an **airtight container**.

HOW DO I REHEAT LEFTOVER CUBES?
The best way to bring back the crispiness of leftover sweet potato cubes is by reheating them in the air fryer. Simply place them back in the air fryer basket (in a single layer if possible) and air fry at 375º F (190º C) for 3-5 minutes, or until thoroughly heated through and re-crisped.

-
Using a sharp knife, cut the skinned potatoes into uniform 1-inch cubes. Consistent sizing ensures even cooking.
-
In a medium mixing bowl, combine the cubed potatoes with the olive oil, garlic powder, and black pepper. Mix well with a spatula to ensure every cube is evenly coated with oil and spices.
-
Add the seasoned potatoes to the prepared and preheated air fryer basket in a single layer. Avoid overcrowding; if necessary, cook in multiple batches to allow hot air to circulate properly for maximum crispiness.
-
Air fry the potatoes at 400º F (200º C) for 15-20 minutes, making sure to shake the basket halfway through the cooking time (around 7-10 minutes).

Notes
Do not overcrowd the air fryer basket. For the crispiest results, the potato cubes must be arranged in a single layer without overlapping. If you have a larger quantity, cook in several smaller batches. Crowding will trap moisture and prevent the potatoes from crisping, leading to a steamed texture instead.
For the best texture, serve the sweet potato cubes immediately after cooking. The delicious crispy edges, which are the hallmark of this air fryer recipe, will soften slightly as the potatoes cool.
