The Quest for Perfectly Crispy Sweet Potato Fries
For years, whenever my family and I would dine out, sweet potato fries were always my go-to side dish. There’s something undeniably satisfying about their sweet and savory flavor profile, especially when paired with a creamy dipping sauce. However, the joy was often tempered by the additional cost – a few extra dollars that quickly added up. Determined to replicate that restaurant experience at home without breaking the bank, I embarked on a mission to find the perfect cooking method. I tried countless oven-baked recipes, both for homemade and frozen sweet potato fries, but they consistently fell short. The results were often limp, unevenly cooked, or simply lacked that glorious, crispy exterior we all crave.
Then, a revelation entered my kitchen: the air fryer. This countertop appliance promised a healthier way to enjoy fried foods, using circulating hot air to achieve a crispy texture with minimal to no oil. Skeptical but hopeful, I decided to give it a try with a bag of frozen sweet potato fries. The results were nothing short of miraculous. In just minutes, my basic frozen fries transformed into golden, perfectly crisp, and incredibly delicious side dishes that rivaled any restaurant offering. This wasn’t just a convenient cooking method; it was a total game-changer, eliminating the need to pay extra for that beloved side. Now, for just a couple of dollars, you can enjoy an amazing meal at home!
And because no plate of sweet potato fries is complete without an incredible dipping sauce, I’m also sharing my secret recipe for homemade curry mayonnaise. It’s the ultimate accompaniment, though you can certainly use any sauce you prefer or enjoy them plain. Let’s dive into making these irresistible air fryer sweet potato fries!

Essential Ingredients for Your Crispy Fries
One of the best aspects of this recipe is its simplicity. You truly only need one main ingredient to achieve spectacular results.
- Frozen Sweet Potato Fries: The star of our show! You’ll need a bag of your favorite brand of frozen sweet potato fries. Most commercial frozen fries are pre-coated with a thin layer of oil, which is exactly why you don’t need to add any additional oil for air frying. This pre-coating helps them crisp up beautifully in the hot circulating air.
Equipment You’ll Need
To achieve the best air fryer sweet potato fries, the right equipment is key. Unsurprisingly, you will need an air fryer!
I personally use a Ninja basket-style air fryer, which has consistently delivered fantastic results. However, the beauty of air frying is its versatility. You can use any brand or model of air fryer you own, whether it’s a basket style, oven style, or even a combo appliance. Just remember that cooking times and temperatures can vary slightly between different makes and models. For this reason, it’s always a good idea to check your fries frequently during the cooking process, especially the first time you try this recipe, to ensure they’re cooking perfectly and not over-browning. Adjust timings as needed based on your specific appliance.
How to Make Irresistibly Crispy Frozen Sweet Potato Fries in an Air Fryer
Creating perfectly crispy frozen sweet potato fries in your air fryer is incredibly simple. Follow these steps for golden, delicious results every time.

Step 1: Preheat Your Air Fryer. Just like a conventional oven, preheating your air fryer is crucial for even cooking and optimal crispiness. Preheat your air fryer to 360°F (180°C) according to your manufacturer’s instructions, or simply run it for 3 minutes to bring it up to temperature.
Step 2: Add Your Sweet Potato Fries. Once preheated, carefully add your frozen sweet potato fries to the air fryer basket. The key to maximum crispiness is to arrange them in a single, even layer. Overcrowding the basket prevents proper air circulation, which is essential for that coveted crispy texture. If you’re cooking a larger quantity of fries, it’s always better to work in batches to ensure each fry gets enough space to crisp up.
Step 3: Cook and Shake. Place the basket back into the air fryer and cook for 15-18 minutes. Halfway through the cooking time (around the 7-9 minute mark), pause the air fryer and give the basket a good shake. This ensures that all sides of the fries are exposed to the hot air, leading to even browning and crispiness. Continue cooking until your sweet potato fries are beautifully golden brown and delightfully crunchy. Cooking times may vary, so keep an eye on them.

Step 4: Serve Immediately. Once cooked to perfection, remove the crispy sweet potato fries from the air fryer and serve them immediately. They are best enjoyed hot and fresh! Sprinkle with a pinch of salt if desired, and don’t forget your favorite dipping sauce, like our delicious homemade curry mayo.
Optimal Batch Size for Best Results
Understanding how batch size affects cooking is vital for achieving consistently great air fryer sweet potato fries. If you’re cooking a small amount of fries, they will naturally cook faster and crisp up more quickly due to less moisture and more air circulation. It’s crucial to check on them frequently to prevent burning. Conversely, when preparing a larger batch of fries, you’ll need to shake the basket more often throughout the cook time to ensure even cooking, and you’ll likely need to extend the cooking duration by a few minutes. For very large quantities of frozen sweet potato fries, I strongly recommend cooking them in multiple batches. This approach guarantees that every single fry has enough space to cook thoroughly and become perfectly crispy, rather than steaming in an overcrowded basket.

Homemade Curry Mayo: The Perfect Dipping Companion
While crispy sweet potato fries are fantastic on their own, pairing them with an exceptional dipping sauce takes the experience to another level. My absolute favorite sauce for sweet potato fries is curry mayo. It offers a unique blend of creamy richness with a hint of exotic spice that perfectly complements the sweetness of the fries. Since it’s not always readily available in stores, I always opt to make my own, and it’s surprisingly simple!
Simple Curry Mayo Recipe
Here’s how you can whip up a batch of delicious homemade curry mayo in minutes:
- ½ cup real mayonnaise (use a good quality brand for the best flavor)
- 1 – 1 ½ teaspoons curry powder (adjust to your spice preference)
- 1 teaspoon fresh lemon or lime juice (for a touch of brightness)
Simply whisk all the ingredients together in a small bowl until the mixture is smooth and well combined. I personally find that allowing the curry mayo to chill in the refrigerator for about 30 minutes before serving enhances the flavors and allows them to meld beautifully, but this step is entirely optional if you’re short on time. Serve immediately and watch it disappear!

Troubleshooting & Tips for Success
Even with a simple recipe like this, a few common questions might arise. Here are some tips to ensure your air fryer sweet potato fries are always a success:
- My fries aren’t crispy enough! The most common reason for less-than-crispy fries is overcrowding the air fryer basket. Remember to cook in a single layer and in batches if necessary. Also, ensure your air fryer is preheated and don’t be afraid to add an extra minute or two to the cooking time if they need it. Shaking the basket vigorously halfway through is crucial for even exposure to hot air.
- Can I add seasoning? Absolutely! While most frozen sweet potato fries come pre-seasoned, a little extra flavor can always be added. After cooking, toss them with a pinch of salt, garlic powder, paprika, or a sprinkle of chili powder for an extra kick.
- Storing and reheating leftover fries: If you happen to have any leftovers (a rare occurrence!), store them in an airtight container in the refrigerator for up to 2-3 days. To reheat, simply pop them back into the air fryer at 350°F (175°C) for 3-5 minutes until they are hot and crisp again. Avoid the microwave, as it will make them soggy.
Health Benefits of Sweet Potatoes
Beyond their incredible taste, sweet potatoes are also packed with nutritional benefits, making them a smart choice for a side dish. They are an excellent source of beta-carotene, which the body converts into Vitamin A, essential for good vision and immune function. Sweet potatoes also provide a significant amount of Vitamin C, Manganese, and dietary fiber, contributing to digestive health and helping you feel full and satisfied. By air frying them, you’re enjoying all these benefits with minimal added fat, making this recipe a healthier alternative to deep-fried versions.

Notes
Curry Mayo Recipe:
- ½ cup real mayonnaise
- 1 ½ teaspoons curry powder
- 1 teaspoon lemon or lime juice
Whisk the ingredients together until smooth. I like to let mine chill for 30 minutes or so before serving, but that’s not a necessary step!
Batch Size: If you are cooking a small amount of fries, they will be done sooner. It’s important to check on your fries to ensure they don’t burn! If you are cooking a large batch of fries, they will need to be shaken a few times through the cook time, and you will likely have to cook them for a bit longer too. I recommend working in batches if you need to cook a very large amount of frozen sweet potato fries.
