Sweet potatoes have gained immense popularity as a healthy and delicious alternative to traditional potatoes, especially when prepared in an air fryer. If you’ve ever wondered, why soak sweet potatoes before air frying, you’re not alone. Soaking sweet potatoes may seem like an extra step, but it plays a vital role in achieving perfectly crispy, golden-brown sweet potato fries.
In this article, we’ll dive deep into the science behind soaking sweet potatoes, why this method improves texture, and how you can do it effectively. Whether you’re a health-conscious eater or just someone who loves crispy fries, you’ll find that understanding the soaking method is key to mastering air-fried sweet potato fries.
The Benefits of Air Frying Sweet Potatoes
Air frying has revolutionized the way we cook, providing a healthier alternative to deep frying without sacrificing flavor or texture. One of the most nutritious vegetables to air fry is the sweet potato. Not only do they taste great, but they also offer a plethora of health benefits, from being packed with vitamins A and C to being rich in dietary fiber and antioxidants.
However, to get the perfect crispy texture from your air-fried sweet potatoes, there’s one trick you shouldn’t skip: soaking. But why does soaking sweet potatoes before air frying make such a difference? Let’s explore the reasons in depth.
Why Soak Sweet Potatoes Before Air Frying?
One of the most critical steps in creating perfectly crispy sweet potato fries in an air fryer is soaking them in cold water before cooking. Soaking offers several benefits, including:
- Removal of excess starch: Sweet potatoes contain starch, which can hinder their ability to crisp up properly. Soaking removes some of this starch, allowing the fries to develop a crispy exterior.
- Even cooking: Soaking ensures that the fries cook more evenly, preventing sogginess in some areas while avoiding dryness in others.
- Reduced cooking time: By removing the surface starch, the fries crisp faster, making soaking a time-saver in the long run.
Incorporating this simple step into your routine can drastically improve the texture of your air-fried sweet potatoes, leaving you with fries that are crispy on the outside and soft and fluffy on the inside.
What Happens If You Skip Soaking?
If you choose to skip soaking, you may end up with less crispy fries. Without soaking, the fries can stick together in the air fryer basket, making it harder for the hot air to circulate and cook them evenly. The result? Fries that may be soggy or unevenly cooked. For those aiming to achieve that perfect combination of a crispy outside and a soft inside, soaking is an essential step.
Soaking and Starch Reduction
Sweet potatoes, much like regular potatoes, have a high starch content. According to a study published by the National Institutes of Health, starch plays a crucial role in how foods brown and crisp. By soaking sweet potatoes, you effectively draw out some of this starch, which allows the outside of the fries to crisp up beautifully without drying out the inside.
This step is key to achieving that golden, crunchy texture that people love in air-fried foods. Plus, the reduced starch allows the sweet potatoes to cook more quickly, meaning you’ll spend less time waiting for your fries to crisp up.
How Long Should You Soak Sweet Potatoes Before Air Frying?
So, how long should you soak sweet potatoes before air frying? The answer depends on how much time you have and how crispy you want your fries to be. The longer you soak the potatoes, the more starch you’ll remove, and the crispier your fries will be. Here’s a quick guide:
- 30 minutes: A quick soak is better than no soak. Even a short soak of 30 minutes will remove a decent amount of starch, helping your fries to crisp up nicely.
- Up to 2 hours: If you have extra time, soak your sweet potatoes for up to two hours. The longer soak removes more starch, resulting in fries that are crispier on the outside and tender on the inside.
- Overnight: For those who want to maximize their results, you can soak sweet potatoes overnight in the refrigerator. This is particularly helpful if you’re prepping for a big meal ahead of time.
No matter how long you soak the sweet potatoes, always make sure to drain and dry them thoroughly. Any residual moisture can create steam during the cooking process, which prevents the fries from becoming crispy.
Step-by-Step Guide: How to Soak and Prepare Sweet Potatoes for Air Frying
Here’s a simple, step-by-step guide to soaking and preparing your sweet potatoes before air frying them:
Step 1: Cut the Sweet Potatoes into Even Strips
First, cut the sweet potatoes into evenly sized strips. This will ensure that they will cook evenly in the air fryer. Aim for pieces that are about ¼ inch thick for the best results. If your fries are too thick, they may not crisp up as well.
Step 2: Soak the Sweet Potatoes
Next, place the sweet potato strips in a large bowl filled with cold water. Let them soak for at least 30 minutes, but if possible, aim for a longer soak of up to 2 hours. Soaking helps to remove starch, which is the key to achieving that crispy texture.
Step 3: Drain and Pat Dry
Once the soaking time is up, drain the water and pat the sweet potatoes dry with a kitchen towel. It’s crucial to remove as much moisture as possible, as excess water can create steam and prevent the fries from crisping in the air fryer.
Step 4: Season the Sweet Potatoes
Toss the sweet potatoes with a small amount of olive oil, salt, pepper, and any seasonings of your choice. Some popular seasoning options include paprika, garlic powder, and cumin. These seasonings not only enhance the flavor of the fries but also help them to develop a beautiful color and extra crispiness.
Step 5: Preheat the Air Fryer
Preheat the fryer to 200°C (400°F) before placing the sweet potatoes in the fryer. Preheating ensures that the sweet potatoes start cooking at the right temperature immediately, helping them to crisp up faster.
Step 6: Air Fry the Sweet Potatoes
Place the sweet potato fries in a single layer in the air fryer basket, making sure not to overcrowd them. Uneven cooking and soggy fries can result from overcrowding. Air fry the sweet potatoes at 400°F for 15 to 20 min, shaking the basket halfway through the cooking time to ensure even cooking.
Alternative Methods: When You Don’t Need to Soak Sweet Potatoes
Although soaking sweet potatoes before air frying can enhance their crispiness, there are times when you can skip this step. For example, when preparing baked sweet potatoes in the air fryer, soaking isn’t necessary. Since baked sweet potatoes aren’t intended to be crispy, you can omit the soaking process and still achieve delicious, tender results.
Sweet Potato Wedges and Cubes
Similarly, some air fryer recipes for sweet potato wedges or cubed sweet potatoes don’t require soaking. These cuts of sweet potato tend to have more surface area exposed to the hot air, which allows them to crisp up more easily without needing to soak. Just be sure to adjust your cooking time based on the size of the pieces.

Do Sweet Potatoes Need to Be Soaked Like Regular Potatoes?
While regular potatoes have a higher starch content than sweet potatoes, soaking can still improve the texture of both. Many people soak white potatoes to remove a significant amount of starch, which prevents them from becoming too soft or soggy.
But how does this compare to sweet potatoes? Even though sweet potatoes contain less starch, soaking them still yields a crispier result. As Harvard’s Nutrition Source highlights, sweet potatoes are also rich in fiber and vitamins, making them a nutritious addition to any meal. So, soaking them benefits not only the texture but also helps retain their valuable nutrients during cooking.
Soaking Regular Potatoes vs. Sweet Potatoes
- Regular potatoes: Typically require soaking to remove a large amount of starch, which helps them crisp up beautifully.
- Sweet potatoes: While they contain less starch, soaking them still enhances their texture and creates the perfect balance of crispiness and tenderness.
If you’re a fan of both sweet potatoes and regular potatoes, you may want to experiment with soaking both varieties and compare the results.
Additional Tips for Crispy Sweet Potato Fries in an Air Fryer
Soaking is just one part of the equation when it comes to making the best sweet potato fries. There are several other tips and tricks that can help you achieve optimal results:
1. Use Cornstarch for Extra Crispiness
One trick to make your sweet potato fries even crispier is to toss them in a light coating of cornstarch before air frying. Cornstarch absorbs excess moisture and creates a crispy exterior, giving your fries that extra crunch you’re looking for.
2. Don’t Overcrowd the Air Fryer Basket
It’s tempting to throw a large batch of sweet potato fries into the air fryer all at once, but overcrowding can lead to uneven cooking. Be sure to arrange the fries in a single layer with space between each fry. If you’re making a larger batch, cook the fries in batches to ensure they all crisp up perfectly.
3. Flip or Shake Halfway Through
Halfway through the cooking process, take a moment to shake the air fryer basket or flip the sweet potato fries. This will ensure that all sides of the fries are exposed to the hot air and will crisp up evenly.
4. Preheat Your Air Fryer
Preheating your air fryer is an often overlooked step, but it’s crucial for achieving crispy fries. Preheating allows the sweet potatoes to start cooking at the right temperature immediately, reducing the risk of soggy fries.
5. Adjust Cooking Times for Different Air Fryers
Not all air fryers are created equal, and cooking times may vary depending on the model you’re using. It’s always a good idea to check on the fries a few minutes before the recommended cooking time is up to ensure they’re cooking evenly.
