With the air fryer, you can achieve a perfectly tender inside with a crispy, flavorful skin. But one of the most common questions is, “How long does a whole sweet potato take in the air fryer?”
In this comprehensive guide, we’ll explore the ins and outs of cooking whole sweet potatoes in the air fryer. From selecting the right sweet potatoes and prepping them properly to setting the correct time and temperature, you’ll learn everything you need to know to get perfect results every time.
Why Cook a Whole Sweet Potato in the Air Fryer?
Benefits of Cooking a Whole Sweet Potato in the Air Fryer
Using an air fryer to cook a whole sweet potato comes with several advantages:
- Time Efficiency: The air fryer cooks faster than a conventional oven, cutting down your cooking time significantly while still delivering a perfectly cooked sweet potato.
- Even Cooking: The air fryer circulates hot air around the sweet potato, ensuring it cooks evenly. This means you get a fluffy, tender interior and a crisp, caramelized skin without any burnt spots or undercooked sections.
- Healthier Cooking: One of the key benefits of using an air fryer is the ability to cook with minimal oil. This results in a healthier dish with fewer calories and less fat, while still maintaining great taste and texture.
Nutritional Benefits of Whole Sweet Potatoes
Whole sweet potatoes are a powerhouse of nutrition:
- Vitamins and Minerals: Sweet potatoes are rich in vitamins A and C, which are crucial for immune function and skin health. They also provide a good amount of potassium, manganese, and dietary fiber, which support various bodily functions.
- Antioxidants: Sweet potatoes contain high levels of beta-carotene, an antioxidant that converts to vitamin A in the body and is essential for eye health and immune function.
- Low Glycemic Index: Despite their natural sweetness, sweet potatoes have a low glycemic index, meaning they cause a slower rise in blood sugar levels, making them a good choice for people managing diabetes or blood sugar levels.
Selecting the Right Whole Sweet Potatoes for the Air Fryer
Different Varieties of Sweet Potatoes
Not all sweet potatoes are the same. The variety you choose can affect both the flavor and cooking time when using an air fryer.
- Orange-Fleshed Sweet Potatoes: These are the most common and have a sweet, moist interior. They caramelize beautifully in the air fryer, making them ideal for those who prefer a traditional sweet potato flavor.
- Purple Sweet Potatoes: Known for their striking color and slightly earthier flavor, purple sweet potatoes are denser and take a bit longer to cook. However, they are just as delicious and visually appealing when prepared in an air fryer.
- White Sweet Potatoes: These have a milder flavor and firmer texture compared to the orange variety. When cooked in an air fryer, they develop a crispy skin with a tender inside, making them a great choice for those who prefer a less sweet taste.
Choosing the Best Whole Sweet Potatoes for Air Frying
When selecting whole sweet potatoes to cook in the air fryer, keep the following tips in mind:
- Size and Shape: Opt for medium-sized sweet potatoes (about 5-7 ounces each). They cook more evenly and fit well in the air fryer basket. Choosing sweet potatoes that are uniform in size ensures they all cook at the same rate.
- Firmness: Look for sweet potatoes that are firm to the touch with no soft spots, cracks, or bruises. Soft spots can indicate spoilage, which will affect the taste and texture.
- Skin Quality: The skin should be smooth and free from any major blemishes. A good-quality skin helps the sweet potato retain its moisture and cook evenly in the air fryer.
Prepping a Whole Sweet Potato for the Air Fryer
Washing and Drying the Whole Sweet Potato
Before cooking your whole sweet potato in the air fryer, proper preparation is essential:
- Washing: Sweet potatoes often come with dirt and debris on their skin since they grow underground. Rinse them thoroughly under cold water, using a vegetable brush to remove any stubborn dirt. Even if you plan to eat the skin, this step is crucial for cleanliness.
- Drying: After washing, pat the sweet potatoes dry with a clean kitchen towel or paper towels. Ensuring the sweet potato is dry will help the skin become crispy when cooked in the air fryer.
Poking Holes in the Whole Sweet Potato
Poking holes in your whole sweet potato before cooking is an important step that should not be overlooked:
- Why It’s Important: Poking holes allows steam to escape during cooking, which helps prevent the sweet potato from bursting. It also ensures that the sweet potato cooks evenly from the inside out.
- How to Do It: Use a fork to poke several holes around the sweet potato. Typically, 4-6 holes are sufficient. Make sure the holes are evenly spaced around the potato.
Adding Oil and Seasoning (Optional)
While you can cook a whole sweet potato in the air fryer without any oil, adding a little can enhance the flavor and texture:
- Oil: Lightly coat the sweet potato with a small amount of olive oil or avocado oil. This helps the skin crisp up nicely and adds a subtle richness to the flavor.
- Seasoning: Sprinkle a little salt and pepper on the sweet potato if you like. For a sweeter version, you can add a pinch of cinnamon or a drizzle of honey before cooking.

Setting Up Your Air Fryer for Whole Sweet Potatoes
Proper setup of your air fryer is key to achieving perfectly cooked sweet potatoes:
- Preheating: Preheat your air fryer to 375°F (190°C). Preheating helps ensure that your sweet potatoes cook evenly and reduces the overall cooking time.
- Basket Preparation: Lightly coat the air fryer basket with cooking spray or a small amount of oil to prevent sticking. This step is especially important if you’ve coated your sweet potatoes with oil.
Optimal Time and Temperature for Cooking a Whole Sweet Potato in the Air Fryer
The cooking time for a whole sweet potato in the air fryer depends on its size and the model of your air fryer. However, the following guidelines will help you achieve the best results:
- Temperature: Set your air fryer to 375°F (190°C). This temperature allows the sweet potato to cook through while developing a crispy, caramelized skin.
- Cooking Time: For medium-sized sweet potatoes (about 5-7 ounces each), cook for 35-45 minutes. Larger sweet potatoes may require up to 50 minutes. Check for doneness by inserting a fork or knife into the thickest part of the sweet potato. If it slides in easily, the sweet potato is done.
Tips for Perfectly Cooked Whole Sweet Potatoes
To ensure your whole sweet potatoes turn out perfectly every time, keep these tips in mind:
- Flip Halfway Through: To promote even cooking, flip the sweet potatoes halfway through the cooking time. This helps them cook evenly on all sides and ensures the skin crisps up properly.
- Check for Doneness: Start checking your sweet potatoes a few minutes before the estimated cooking time is up. If they are still firm in the center, continue cooking in 5-minute increments until they are tender.
- Avoid Overcrowding: Don’t overcrowd the air fryer basket. Make sure there is enough space between the sweet potatoes for air to circulate freely, which ensures even cooking.

Storing and Reheating Air-Fried Whole Sweet Potatoes
How to Store Leftover Whole Sweet Potatoes
If you have leftover air-fried whole sweet potatoes, proper storage will help maintain their quality:
- Refrigeration: Store leftover sweet potatoes in an airtight container in the refrigerator. They will stay fresh for up to 4-5 days. If you’re planning to use them in salads or as a quick snack, slice them before storing for easy access.
- Freezing: For longer storage, you can freeze air-fried sweet potatoes. Place them in a single layer on a baking sheet and freeze until solid. Then transfer them to a freezer-safe container or bag, where they will keep for up to 3 months. When you’re ready to eat them, reheat them in the air fryer for a few minutes to restore their crispy texture.
Reheating Whole Sweet Potatoes
To enjoy your leftover air-fried whole sweet potatoes, follow these reheating tips:
- Air Fryer: Reheat the sweet potatoes in the air fryer at 350°F (175°C) for 5-7 minutes, or until warmed through and crispy. This method will give you the best results, restoring the potato’s crispy skin and fluffy interior.
- Oven: Preheat your oven to 375°F (190°C) and reheat the sweet potatoes on a baking sheet for 10-15 minutes. This method is ideal for maintaining the crispy exterior.
- Microwave: While the microwave is the quickest option, it may result in a softer sweet potato. If you choose this method, heat the sweet potatoes in 30-second intervals until warm. To add a bit of crispness back to the skin, you can finish them in the air fryer for a couple of minutes after microwaving.
FAQs About Cooking Whole Sweet Potatoes in the Air Fryer
Can I Cook Sweet Potatoes Without Poking Holes?
While it’s possible to cook sweet potatoes without poking holes, it’s not recommended. Poking holes allows steam to escape, which helps prevent the sweet potatoes from bursting during cooking and ensures even cooking throughout. Without holes, the pressure inside the potato could build up, leading to an unevenly cooked potato or even an explosion in the air fryer.
Do I Need to Preheat My Air Fryer?
Preheating your air fryer is highly recommended for cooking whole sweet potatoes. Preheating helps the sweet potatoes cook evenly and shortens the overall cooking time. If your air fryer does not have a preheat function, simply run it at the cooking temperature for 3-5 minutes before adding the sweet potatoes. This will ensure that the air fryer is hot enough to start cooking the potatoes right away, leading to better results.
How Can I Tell When My Sweet Potatoes Are Done?
The best way to check if your sweet potatoes are done is to insert a fork or knife into the thickest part of the potato. If it slides in easily with little resistance, the sweet potato is fully cooked. The skin should also be slightly crispy, and the interior should be soft and fluffy. If the potato still feels firm, continue cooking it in 5-minute increments until it’s tender throughout.
Can I Cook Multiple Sweet Potatoes at Once in the Air Fryer?
Yes, you can cook multiple whole sweet potatoes in the air fryer, but it’s important not to overcrowd the basket. Make sure the sweet potatoes are not touching each other and that there is enough space for air to circulate around them. Overcrowding can lead to uneven cooking, with some potatoes being overcooked while others remain underdone. You may need to adjust the cooking time slightly depending on how many sweet potatoes you are cooking.
How Can I Make the Skin of My Whole Sweet Potato Crispier?
To achieve a crispier skin, lightly coat the sweet potatoes with oil before cooking them in the air fryer. Additionally, you can increase the temperature to 400°F (200°C) for the last 5 minutes of cooking. Just be sure to monitor the sweet potatoes closely to prevent burning. The high heat at the end will help the skin crisp up even more, giving you that perfect contrast between the crunchy exterior and the soft interior.
