Sweet Potatoes

For this recipe, we recommend using sweet potatoes with a deep orange flesh and brow-reddish peel. These are the most common and widely available varieties, offering a perfect balance of sweetness and texture. When selecting, choose firm, unblemished potatoes. Approximately 1.5 pounds (about 3 medium-sized sweet potatoes) will yield 4 servings when cut into 1-inch (2.5 cm) cubes.

Olive Oil

Olive oil is crucial for achieving that desirable golden-brown exterior and ensuring the sweet potato cubes cook evenly and faster. The oil acts as a heat conductor, distributing the hot air efficiently. We typically use extra virgin olive oil for its superior flavor and stability at higher temperatures, but regular olive oil or avocado oil are also excellent alternatives. A light coating is all that’s needed to prevent sticking and promote caramelization.

Spices and Herbs

While sweet potatoes are flavorful on their own, a simple blend of spices can elevate them dramatically. We love adding paprika (for a touch of warmth and color) and garlic powder (for an aromatic depth) to our sweet potato cubes before air frying. Feel free to customize this with your favorite seasonings:

• Smoked Paprika: Adds a beautiful smoky note.
• Chili Powder or Cayenne: For a little kick.
• Onion Powder: Complements garlic powder.
• Cumin: Earthy and warm, especially good for savory dishes.
• Rosemary or Thyme: Fresh or dried herbs for an aromatic touch.
• Cinnamon or Nutmeg: For a sweeter profile, especially if serving as a dessert or breakfast side.

Always remember to season with salt and black pepper to taste for optimal flavor balance.

Making delicious sweet potato cubes in your air fryer is incredibly simple. Follow these steps for perfect results every time:

1. Prepare the Sweet Potatoes: Begin by peeling the sweet potatoes using a vegetable peeler. Once peeled, use a sharp knife to cut them into uniform 1-inch (2.5 cm) cubes. Uniformity is key for even cooking.

   

2. Season Generously: Transfer the sweet potato cubes to a large mixing bowl. Drizzle them with olive oil, then sprinkle with salt, black pepper, paprika, and garlic powder. Toss everything together thoroughly until all the cubes are evenly coated with the oil and spices. This ensures every piece is flavorful.

   

3. Load the Air Fryer Basket: Transfer the seasoned sweet potato cubes into your air fryer basket. It’s perfectly fine for the cubes to overlap slightly; there’s no strict need to arrange them in a single layer, especially for cubes. However, avoid overcrowding the basket too much to allow for good air circulation.

   

4. Air Fry to Perfection: Air fry the sweet potato cubes at 400°F (200°C) for approximately 13 to 15 minutes. To ensure even cooking and browning, remember to shake the air fryer basket every four minutes. This prevents some pieces from becoming overly crispy while others remain undercooked.

   

5. Serve and Enjoy: Once cooked to your desired tenderness and crispness, transfer the golden-brown sweet potato cubes onto a serving platter. Enjoy them as a standalone snack, a fantastic side dish, or with your favorite dipping sauces. Great options include vegan sour cream, creamy avocado dip, nutty tahini sauce, a squeeze of fresh lemon juice, or a sprinkle of fresh parsley for brightness.

   

Baked sweet potato in the air fryer is incredibly quick and yields a wonderfully tender interior with a slightly crisp skin. It’s perfect for filling with your favorite toppings or enjoying simply with a touch of butter and sage.

Whole sweet potatoes take significantly less time to cook in an air fryer – typically around 20 minutes – compared to 45 minutes to an hour in a conventional oven. They emerge perfectly tender throughout, sweet, and naturally caramelized, often with delightful, slightly charred, smokey notes on the skin. This makes them an ideal choice for a nutritious and tasty dinner or a substantial side.

Instructions for Whole Baked Sweet Potatoes:

1. Prepare: Wash the sweet potatoes thoroughly. Pierce them several times all over with a fork. This allows steam to escape and prevents them from bursting.
2. Air Fry: Place the pierced sweet potatoes directly into the air fryer basket.
3. Cook: Air fry at 400°F (200°C) for about 20 minutes, or until they are fork-tender inside. The exact cooking time can vary based on the size and thickness of your sweet potatoes. Larger potatoes may need a few extra minutes.
4. Serve: Once cooked, carefully remove them from the air fryer. Cut them open lengthwise with a knife and fluff the interior with a fork. Load with your favorite toppings!

Our favorite toppings for baked sweet potatoes include:

Butter and Sage

For a rich and aromatic treat, gently fry a few fresh sage leaves in a small knob of butter (dairy-free butter works wonderfully too). Drizzle this infused butter over the hot baked potato, add a pinch of sea salt, and savor the simple yet profound flavors.

Black Bean and Quinoa Fiesta

Turn your baked sweet potato into a fulfilling, protein-packed meal using our black bean quinoa salad. Prepare the salad as directed (excluding any sweet potato cubes it might include), then generously stuff it into the warm sweet potato. This pairs beautifully with a dollop of our creamy avocado spread and a swirl of vegan sour cream.

Mediterranean Inspired Goodness

For a refreshing and vibrant meal, fill your baked sweet potato with our light and zesty couscous salad, a handful of crispy roasted chickpeas, thinly sliced olives, and crumbled feta cheese. Finish with a generous drizzle of freshly squeezed lemon juice for a burst of Mediterranean flavor.

Tahini Drizzled Delight

Infused with Middle-Eastern and Mediterranean flavors, this variation features an air fryer baked sweet potato loaded with our savory couscous with vegetables. It’s then topped with perfectly crispy air fryer chickpeas and finished with a rich, creamy tahini sauce drizzle. This combination offers incredible texture and depth of flavor.

Cinnamon and Maple Syrup Sweet Treat

For a comforting sweet treat or a delightful breakfast option, scoop the soft baked sweet potato flesh out onto a plate. Lightly mash it with a fork, retaining some of its shape. Top with a small knob of butter, a generous sprinkle of cinnamon, and a hint of freshly grated nutmeg. Drizzle with 100% pure maple syrup and scatter some crushed walnuts over the top for added texture and richness.

Air fryer sweet potato wedges are a fantastic alternative to cubes, offering a satisfying bite and a larger surface area for seasoning. You can prepare them with the peel on or off. If keeping the skin on, ensure you scrub the sweet potatoes very well under running water before cutting.

Instructions for Sweet Potato Wedges:

1. Prepare: Wash and scrub the sweet potatoes. Cut each sweet potato in half lengthwise, then cut each half into several wedges (usually 4-6, depending on the potato size).
2. Season: In a large bowl, toss the sweet potato wedges with olive oil, salt, pepper, two crushed garlic cloves (or garlic powder), and finely chopped fresh rosemary (or dried rosemary). Mix until well coated.
3. Air Fry: Transfer the seasoned wedges into the air fryer basket. They can overlap, but avoid seriously overcrowding the basket to ensure they cook properly. You might need to cook in batches if you have a smaller air fryer.
4. Cook: Air fry for about 15 to 20 minutes at 400°F (200°C), or until they are tender when pierced with a fork and beautifully golden-brown and slightly crispy on the outside. Remember to shake the basket every 5-7 minutes.
5. Serve: Arrange on a serving platter and enjoy as a delicious side dish with almost any meal.

Air Fryer Sweet Potato Fries

For a lighter, healthier take on fries, the air fryer is your friend. While traditional sweet potato fries can be tricky to get truly crispy due to their natural sugar content, the air fryer delivers a satisfyingly tender interior and a lovely browned exterior.

Instructions for Sweet Potato Fries:

1. Prepare: Peel the sweet potatoes. First, slice the sweet potatoes into thin planks, then cut these planks into uniform sticks (about ¼ to ½ inch thick, similar to classic french fries). Aim for consistency in thickness.
2. Season: In a bowl, toss the sweet potato sticks with olive oil, salt, pepper, garlic powder, and paprika. Ensure every fry is lightly coated.



3. Air Fry: Add the seasoned sweet potato fries to the air fryer basket. They can overlap, but do not overcrowd the basket. Cook in batches if necessary.
4. Cook: Air fry for approximately 13 to 18 minutes at 400°F (200°C), shaking the basket frequently (every 4-5 minutes) to promote even cooking and browning.

Important Note on Crispiness: Sweet potato fries generally will not achieve the same level of crispiness as regular potato fries when cooked this way. This is due to the inherent composition of sweet potatoes; their starch converts to sugar during cooking, which inhibits crisping. Expect them to be tender with a slightly caramelized exterior rather than super-crispy.

We love to serve our sweet potato fries loaded with a vibrant mix of black beans, fresh corn, chopped cilantro, a squeeze of lime juice, creamy avocado, and a drizzle of spicy chipotle sauce for an unforgettable meal!
