The BEST Crispy Homemade Sweet Potato Fries Recipe (2024)

FAQs

Why won't my sweet potato fries get crispy? ›

The secret to crispy (instead of soggy) sweet potato fries is to spread them out in an even layer with enough room so that they don't touch. This is especially important if you're making a big batch of fries. Instead of just piling more onto one baking pan, spread them out over two baking pans or cook them in batches.

Sweet potato fries are slightly higher in calories and carbs but also more nutrient dense than French fries. The greatest nutrient difference is that French fries have no vitamin A, while sweet potato fries are high in this nutrient. Vitamin A is important for your vision and immune system ( 2 ).

If they are still not crispy you might have skipped a step or you might not have let them cool down sufficiently. Make sure to cool them in a single even layer and also make sure that the oil has the right temperature. Or maybe you've used the wrong potatoes to make them.

The Double-Fry Method

When it comes to the actual cooking, you want to fry the french fries twice. The first round is at a lower temperature to cook the inside of the potato and the second time you'll use a higher temperature to make the fries golden brown and crispy.

TIPS & TRICKS to Make this Recipe: The main secrets to achieving that incredible crispy texture, is to soak the cut sweet potatoes in cold water for at least 30 minutes. This helps remove the starch from the sweet potatoes so they´re not limp & soggy.

Place them in a large bowl and cover with cold water. Allow them to soak, 2 to 3 hours. (You can also stick them in the fridge and let them soak overnight.) When you're ready to make the fries, drain off the water and lay the potatoes on 2 baking sheets lined with paper towels.

Corn Starch: Adding a thin coating of corn starch to the potato fries before frying can help create a crispier exterior. When the corn starch comes into contact with the hot oil, it forms a barrier that traps moisture within the potato while also developing a crunchy crust.

The baking soda is clutch, as it alkalizes the water/potatoes and contributes to the crunch effect. The salt goes both in the water and on the potatoes for maximum seasoning. A big glug of olive oil makes them super crunchy and that fat gives the super high heat something to work with.

Blanching: The Reason Why French Fries Taste Better

Your potatoes need to take two separate dips in hot oil to reach restaurant quality. Oil-blanching is a two-part process that reduces the moisture and starch content in your fries, helping them crisp up.

Don't overcrowd the baking sheet!

This is an important one! If the baking sheet it too crowded, the sweet potatoes will not crisp. You should provide optimal space for air to flow through, and the sweet potatoes shouldn't be touching.

How to crisp up soggy sweet potato fries? ›

If your air fryer fries are soggy, it is likely because you over-crowded them in the basket. The sweet potatoes steam when crowded together, instead of air frying. For the best, most crispy results, cook the fries in a single layer so that the air has room to circulate.

Remember, fries are full of water. The more fries you add to a tray, the more steam they'll be releasing in your oven, reducing crispness. Load the oven quickly. This prevents heat loss that can result in soggy fries.
