Sweet potatoes are a delicious and healthy alternative to regular potatoes. When air-fried correctly, they become crispy on the outside and tender on the inside. However, many people struggle with soggy results. If you’ve found yourself asking, “Why are my sweet potatoes soggy in the air fryer?”—you’re not alone.
This article will walk you through the reasons behind soggy air fryer sweet potatoes and provide tips to get perfectly crispy results. Let’s explore why this happens and how to fix it.
How an Air Fryer Works with Sweet Potato
The air fryer works by circulating hot air around the food, creating a crispy exterior similar to deep frying but without the oil. However, sweet potatoes present a unique challenge. Their higher water content can lead to sogginess if not cooked properly.
The Secret to Crispy Sweet Potatoes in the Air Fryer
Achieving crispy air fryer sweet potatoes comes down to understanding the mechanics of air frying. The hot air needs enough space to circulate around the food. Overcrowding the basket is a common mistake that many people make.
Tip: Always arrange your sweet potato slices or cubes in a single layer. This allows the air to flow evenly around each piece, giving them that perfect golden crisp.
Common Mistakes That Lead to a Soggy Air Fryer Sweet Potato
If you’ve tried making air-fried sweet potatoes and they turned out soggy, you might be making one of these common mistakes. Let’s take a look at how these simple errors affect the cooking process.
1. Overcrowding the Air Fryer Basket
One of the main reasons sweet potatoes get soggy is overcrowding the air fryer basket. When too many sweet potatoes are packed into the fryer, the hot air can’t circulate properly. This leads to uneven cooking and soggy results.
Solution: Leave enough space between each slice or cube. If you have a lot of sweet potatoes, cook them in batches. Cooking in batches can make a big difference, as it allows the sweet potatoes to cook evenly without too much moisture trapping between them. Air needs to reach all sides of the food to achieve that crispy texture.
2. Incorrect Temperature Settings
Sweet potatoes need the right amount of heat to crisp up. If the air fryer is set too low, the moisture inside the sweet potatoes doesn’t evaporate quickly enough, which can leave them soggy. Setting the temperature too high can also burn the exterior before the interior is fully cooked.
Solution: For the best results, set your air fryer to 375°F-400°F. This temperature is perfect for cooking sweet potatoes until they’re crispy without drying them out. Experimenting with temperatures within this range is important depending on your air fryer model. Many air fryers vary slightly in how they distribute heat, so feel free to adjust based on your specific appliance.
3. Not Drying Sweet Potatoes Properly
Sweet potatoes naturally contain a lot of moisture. If you don’t dry them well before cooking, this moisture can prevent them from crisping up in the air fryer.
Solution: After washing and cutting your sweet potatoes, make sure to pat them dry thoroughly with a paper towel. Removing excess water is key to avoiding sogginess. This step is often overlooked, but it’s one of the most critical in achieving crispy sweet potatoes.
4. Using Too Little or Too Much Oil
Oil is essential for crispy sweet potatoes, but using the right amount is crucial. If you use too little oil, your sweet potatoes won’t develop a crispy outer layer. On the other hand, using too much oil can make them greasy and soggy.
Solution: Lightly coat your sweet potatoes with a tablespoon or less of oil. A small amount is enough to give them that crispy texture without making them greasy. Using olive oil or avocado oil works best for air fryer recipes. A light coating of oil also helps the sweet potatoes brown evenly, enhancing their flavor and texture.
5. Inconsistent Slicing or Cutting
Another common mistake is inconsistent slicing. Sweet potatoes come in many shapes and sizes, and cutting them unevenly can lead to uneven cooking. Larger pieces may remain soft, while smaller ones burn or overcook.
Solution: Always slice or cube your sweet potatoes evenly. For fries, cut them into uniform ¼-inch thick slices. If you’re making cubes, aim for around 1-inch square pieces. Uniform sizes ensure each piece cooks at the same rate.
6. Skipping Preheating the Air Fryer
Many people skip the step of preheating their air fryer, which can impact the overall cooking time and texture. Preheating ensures that the air fryer reaches the right temperature before cooking begins, which is key for crisping the sweet potatoes’ outer layer.
Solution: Preheat the air fryer for 3-5 minutes at the desired temperature. This simple step helps sweet potatoes start cooking immediately, improving their texture and reducing sogginess.
How to Fix Soggy Sweet Potatoes in the Air Fryer
Now that you know the common mistakes, let’s explore how to make perfect air-fried sweet potatoes step by step. With the right techniques, you can achieve crispy, delicious results every time.
1. Cut Sweet Potatoes Evenly
Cutting your sweet potatoes into uniform pieces is essential for even cooking. Unevenly sized pieces will cook at different rates, leaving some soft and others crispy.
Tip: For fries, aim for ¼-inch thick slices. For cubes, keep them around 1-inch square. Consistent sizing ensures the pieces crisp evenly.
2. Pat Dry and Use Starch for Extra Crispiness
Once you’ve cut your sweet potatoes, pat them dry to remove excess moisture. If you want them extra crispy, toss them with a little cornstarch before adding oil. Cornstarch helps create a crispy coating that mimics deep frying.

3. Preheat the Air Fryer
Many people forget to preheat their air fryer, but this step is essential. Preheating ensures that your sweet potatoes begin cooking as soon as they hit the basket, which helps them crisp up faster.
Tip: Preheat your air fryer for about 3 minutes before adding the sweet potatoes.
4. Flip or Shake Halfway Through Cooking
Another key to crispy air fryer sweet potatoes is flipping them halfway through the cooking process. This ensures all sides are exposed to the circulating hot air.
Tip: Set a timer for halfway through your cooking time to remind you to shake or flip the potatoes.
5. Let Sweet Potatoes Rest After Cooking
Once your sweet potatoes are done, let them sit for a couple of minutes. This short resting period allows the heat to redistribute, which helps to further crisp the outside.

Different Types of Sweet Potatoes and Their Effects on Crispiness
Did you know that the type of sweet potato you use can affect the outcome? Different varieties, such as orange-fleshed, white-fleshed, and purple sweet potatoes, have varying water and starch content, which impacts how they cook in the air fryer.
Orange Sweet Potatoes
Orange-fleshed sweet potatoes are the most common. They are sweet and contain higher moisture content, making them more prone to becoming soggy if not cooked correctly. However, they are delicious when properly air-fried and paired with savory or sweet spices.
White Sweet Potatoes
White-fleshed sweet potatoes are starchier and drier, making them easier to crisp up in the air fryer. They have a slightly less sweet taste than the orange variety, but their firm texture makes them ideal for crispy sweet potato fries.
Tip: If you’re struggling to get the perfect crisp on orange sweet potatoes, try using white-fleshed sweet potatoes for an easier solution.
Purple Sweet Potatoes
Purple sweet potatoes are less common but have a beautiful color and slightly different texture. They tend to be starchy, like white sweet potatoes, which can make them a good option for air frying.
The Role of Seasoning in Crispy Air-Fried Sweet Potatoes
Seasoning plays a big role in how your air-fried sweet potatoes turn out. The right seasoning can elevate the flavor and enhance crispiness. Salt, garlic powder, and paprika are great choices. Some people even like to add a dash of cayenne for extra spice.
For sweeter versions, cinnamon and a drizzle of honey or maple syrup work wonders. Just make sure to add sweet toppings after frying, as sugar can burn in the air fryer.

FAQs about Why are sweet potatoes soggy in air fryer?
Why Soak Sweet Potatoes Before Air Frying?
Soaking sweet potatoes in cold water before air frying is a helpful technique for achieving a crispier result. Soaking helps remove excess starch from the sweet potatoes, which can otherwise trap moisture and lead to a softer texture. By removing some of the starch, the surface of the sweet potatoes becomes more prone to crisping up when exposed to the heat of the air fryer.
How to Soak: After cutting the sweet potatoes, place them in a bowl of cold water for about 30 minutes. After soaking, make sure to pat them dry thoroughly before tossing them in oil and air frying.
Why Are My Sweet Potatoes Soggy in the Air Fryer?
Soggy sweet potatoes are often the result of too much moisture. There are several factors that can lead to sogginess:
Low Temperature: Cooking at a temperature that’s too low can prevent the sweet potatoes from developing a crispy exterior. For best results, cook at 400°F (200°C).
Overcrowding: When the basket is packed too full, the air cannot circulate freely, causing the sweet potatoes to steam rather than fry, leading to a soggy texture.
Excess Moisture: Sweet potatoes that haven’t been properly dried before cooking will release moisture during air frying, resulting in a softer, soggier texture. Always dry your sweet potatoes thoroughly after cutting or soaking.
Why Are My Sweet Potatoes Not Crispy in the Air Fryer?
If your air fryer sweet potato fries or wedges aren’t turning out crispy, there are several possible reasons:
Improper Cutting: Sweet potatoes cut too thick may not cook evenly or get crispy on the outside. Be sure to cut them uniformly and at the right thickness (about 1/4 inch for fries).
Overcrowding: When too many sweet potatoes are in the basket, there’s not enough space for the hot air to circulate, leading to steaming rather than frying. Always cook in small batches.
Lack of Preheating: Failing to preheat the air fryer means the sweet potatoes start cooking at a lower temperature, which can result in a softer texture.
Not Enough Oil: While air fryers require less oil than deep frying, using too little oil can prevent the sweet potatoes from becoming crispy.
Why Do Sweet Potatoes Turn Black in the Air Fryer?
Sweet potatoes can sometimes turn black or dark in spots when cooked in an air fryer, and this typically happens due to natural oxidation or caramelization of sugars. There are two primary reasons for this:
- Oxidation: When sweet potatoes are exposed to air after being cut, the flesh can oxidize and turn dark. While this doesn’t affect the taste, it can make the sweet potatoes appear less visually appealing. To prevent this, cook the sweet potatoes soon after cutting, or store them in water until you’re ready to cook.
- Caramelization: Sweet potatoes are naturally high in sugar, and when they are cooked at high heat, the sugars can caramelize and darken, creating black spots. This is particularly common if you are air frying at a high temperature like 400°F (200°C).
To avoid excessive blackening, ensure the sweet potatoes are evenly coated with oil and that you monitor the cooking process closely, especially during the last few minutes.
Conclusion: Perfect Air-Fried Sweet Potatoes Every Time
Getting crispy sweet potatoes in the air fryer is easy once you know the right steps. By avoiding common mistakes and following these tips, you can enjoy perfectly crispy sweet potatoes every time.
Next time you make air-fried sweet potatoes, remember to cut them evenly, pat them dry, and avoid overcrowding. With these adjustments, soggy sweet potatoes will be a thing of the past!
