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 than French fries but also high in vitamin A — giving them a nutritional edge. Still, deep-fried fries of any kind served in over-sized portions — as in many restaurants — may increase your risk of weight gain and related health problems.

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.

If you'd like, you can soak the sweet potato slices for 30 minutes up to 2 hours before frying to remove excess starch. Personally, though, going through this step didn't make a real difference for my fries. Peels on or off — it's up to you!

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.

If you're pressed for time, the slightly sticky, cut potatoes should be soaked for a minimum of 15 minutes. However, a longer soak time may allow more starch to be removed. So, if you can prep the fries ahead of time, a few hours of soaking can help make them even crispier.

Soaking your fries in cold water helps remove excess starch, which allows for crispy, golden fries! The cold water bath also helps the french fries retain their shape and contributes to a fluffy inside.

But to give you the Cliff's Notes version, the baking soda alkalizes the water. It breaks down the pectin in the potato and brings the natural starches up to the surface. This, when combined with the pot shaking, contributes to deep browning and ultra crunchines that we're looking for.

Banish Soggy Sweet Potato Fries.

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.

A: The main reasons to cut the potatoes and pre-soak in water are: To allow the excess starches and sugars to be removed from the outer surface of the fry strips AND to keep the potatoes from browning prematurely from exposure to air. Covering in water helps the potato from turning a dark color.

Why are my fried sweet potato fries soggy? ›

Don't try frying just once (or if you do… fry them starting off in cold oil). Sogginess is caused by moisture. You want to drive off the moisture from the outside but the inside also contains moisture which will turn to steam and evaporate through the crispy crust of the potato, turning it soggy again.

Parboil them first if you're going to bake them

This can happen because the insides aren't quite cooked enough, but the outsides are beginning to dry out. Don't worry, sweet tuber lovers; there is a solution! This tip is a need-to-know to get the crispiest potato fries ever.

Fries have a very high starch content. When they are cooked at high temperatures, they absorb moisture which gives them their signature crispy exterior. When they are left out to cool, the starches secrete moisture, which eventually makes the fries' crust soggy.

Soak them. I was always a little skeptical when I read this in recipes, but it's essential. Soaking the sweet potatoes removes excess starch, which allows them to crisp up easier. You will want to put them in cold water for at least 30 minutes, but the longer you can go, the better.
