What To Know
- Cooking sweet potato fries at too low a temperature will not create a crispy exterior.
- Fry once at a lower temperature (325°F / 160°C) to cook through, then fry again at a higher temperature (375°F / 190°C) to crisp up.
- Remember, the key to success lies in cutting the fries thinly, not overcrowding the pan or air fryer, preheating the oil or air fryer, cooking at the right temperature, and avoiding overcooking.
Sweet potato fries are a delicious and healthy snack or side dish, but they can often turn out soggy and disappointing. If you’re wondering why your sweet potato fries are soggy, you’re not alone. Many factors can contribute to soggy sweet potato fries, but understanding the causes is the first step to achieving crispy, golden-brown perfection.
The Science Behind Soggy Sweet Potato Fries
To understand why sweet potato fries can become soggy, we need to delve into the science behind their cooking process. Sweet potatoes contain a high amount of starch, which gelatinizes when heated. This gelatinization process causes the fries to absorb water and become soft and mushy.
Factors Contributing to Soggy Sweet Potato Fries
1. Cutting the Sweet Potatoes Too Thickly:
Cutting sweet potatoes too thickly will result in uneven cooking. The thicker parts will take longer to cook, leading to soggy fries. Aim for thin, evenly cut fries for optimal crispiness.
2. Overcrowding the Pan or Air Fryer:
Overcrowding prevents the fries from getting crispy because they steam instead of fry. Spread the fries in a single layer, leaving space between them for air circulation.
3. Not Preheating the Oil or Air Fryer:
Preheating the oil or air fryer ensures that the fries get crispy immediately. Cold oil or air will absorb into the fries, making them soggy.
4. Cooking at Too Low a Temperature:
Cooking sweet potato fries at too low a temperature will not create a crispy exterior. The ideal temperature for frying is between 350°F (175°C) and 375°F (190°C).
5. Overcooking:
Overcooking sweet potato fries will dry them out and make them chewy. Cook until they are golden brown and crispy on the outside, but still tender on the inside.
How to Avoid Soggy Sweet Potato Fries
1. Cut Sweet Potatoes Thinly:
Use a sharp knife to cut the sweet potatoes into thin, even slices. This will ensure even cooking and crispy fries.
2. Don’t Overcrowd the Pan or Air Fryer:
Spread the fries in a single layer, leaving space between them. This allows for air circulation and prevents steaming.
3. Preheat the Oil or Air Fryer:
Preheat the oil or air fryer to the desired temperature before adding the fries. This will create a crispy exterior.
4. Cook at the Right Temperature:
Cook sweet potato fries at a temperature between 350°F (175°C) and 375°F (190°C) for optimal crispiness.
5. Don’t Overcook:
Cook the fries until they are golden brown and crispy on the outside, but still tender on the inside. Overcooking will dry them out and make them chewy.
Tips for Extra Crispy Sweet Potato Fries
1. Soak the Fries in Water:
Soaking sweet potato fries in water for 30 minutes before cooking helps remove excess starch, resulting in crispier fries.
2. Toss with Cornstarch:
Toss the fries with cornstarch before cooking to create an extra crispy coating.
3. Double Fry:
For the ultimate crispy fries, fry them twice. Fry once at a lower temperature (325°F / 160°C) to cook through, then fry again at a higher temperature (375°F / 190°C) to crisp up.

Frequently Asked Questions
1. Why do my sweet potato fries turn brown when I soak them in water?
Soaking sweet potato fries in water can cause them to oxidize and turn brown. To prevent this, add a tablespoon of lemon juice or vinegar to the water.
2. Can I bake sweet potato fries instead of frying them?
Yes, you can bake sweet potato fries at 425°F (220°C) for 20-25 minutes, flipping halfway through. However, baking will not produce the same level of crispiness as frying.
3. How do I reheat soggy sweet potato fries?
To reheat soggy sweet potato fries, place them in an air fryer or oven at 350°F (175°C) for 5-7 minutes, or until crispy again.
