  • Ice bath. Put the sliced sweet potatoes in a large bowl of ice-cold water. Add more ice if required to cover them completely. You can also put the soaked sweet potatoes in the refrigerator for 1-2 hours to make sure they are chilled well. This will help in making them crispy while frying.

  • The first fry. Follow the instructions provided by the manufacturer to prepare the deep fryer. Then, fill it with peanut oil and heat it to 325℉. Next, drain the sweet potatoes and dry them thoroughly using a paper towel. Eliminating any excess moisture is important, as it can cause oil to splatter. Put the sweet potatoes in the fryer basket without worrying about them being slightly crowded. Fry them for 5-7 minutes until they soften and turn light golden. Finally, remove the fries and place them on a baking sheet lined with paper towels to drain.

  • The second fry. Set the heat to 375℉ and fry them again in smaller batches. Make sure they don't touch each other while frying to make sure even cooking and crispiness. Fry them for 2-4 minutes until they turn golden brown and crispy. After frying, place them on fresh paper towels to remove excess oil. While they are hot, add salt and paprika for flavor.

Be careful when deep frying, especially using a Dutch oven.  An electric deep fryer is much safer and gives better results.
Avoid overcrowding the deep fryer, especially during the second frying stage. Frying in smaller batches allows the sweet potato fries to cook evenly and become crispier.
After frying, drain the sweet potato fries on paper towels to remove excess oil. Season them with salt and paprika while they’re still hot to help the seasoning adhere better.
Sweet potato fries taste best when served immediately after cooking. Reheating can cause them to lose some of their crispiness, so enjoy them fresh out of the fryer for the best taste and texture.
Use any seasoning you’d like! Get creative with the seasoning by adding garlic powder, onion powder, cayenne pepper, or your favorite herbs and spices.

More Tips:

Cut the sweet potatoes into evenly sized strips for consistent cooking and crispiness. Uneven sizes may result in some fries being overcooked or undercooked.

Don’t skip soaking the sweet potato strips in ice water, as this helps to remove excess starch and results in crispier fries. The longer you soak the potatoes, the better the texture, up to 12 hours.

After soaking and before frying, use paper towels to pat the sweet potatoes as dry as possible. Excess moisture can cause the oil to splatter and prevent the fries from becoming crispy.

Use a deep-fry thermometer to make sure the oil is at the correct temperature during both frying stages. Proper oil temperature is crucial for achieving crispy and perfectly cooked sweet potato fries.

You can also cook it using an air fryer, but they’ll still be good. Cooking time may vary depending on the air fryer model, so adjust as needed.

Serving Suggestions

Pair this recipe with garlic aioli, spicy chipotle mayo, classic ranch dressing, barbecue sauce, or honey mustard dip.

Here are some substitutions you can try:

  • Peanut Oil: Use canola oil or vegetable oil instead for frying.
  • Sweet Potatoes: Regular russet potatoes or yams are a great alternative.
  • Paprika: Swap for cayenne pepper for more heat or chili powder for a smokier flavor.
  • Salt: Try sea salt flakes or smoked salt for a different twist.

However, remember that these substitutions may change the taste and texture of your fries. But it’s worth trying them out to see which one you like the best!

Storage Instructions

Allow the fries to cool completely: Before storing, let the sweet potato fries cool down to room temperature on a paper-towel-lined baking sheet to avoid any moisture buildup.

Place the sweet potato fries in the refrigerator in an airtight container or a resealable plastic bag. They will keep well for up to 3-4 days.

Heat in a 390-degree air fryer for about 5 minutes. A conventional oven will work well, too.
