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.

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.

Additionally, restaurant fries are so crispy because, among other things, they use old oil continuously. As oil heats up it breaks down—cooking oils with a high smoke point will break down more slowly—and that creates crispier fries.

A properly made fry must hit the oil twice--once at a lower temperature, and then again at 350 degrees Fahrenheit--to get the perfect creamy interior and crunchy exterior. Before all that, though, the secret is to briefly poach them in boiling water (or "blanch" them) before they go into the hot oil.

Ensure that the fries are evenly spaced out on a parchment-lined baking sheet so that they aren't touching. If the fries are touching, they will steam rather than bake, which leads to soggy, sad fries. The parchment paper prevents the fries from sticking to the sheet.

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.

Long accepted as a standard deep frying oil because of its neutrality, high smoke point, and ready availability (on the bottom oil shelf of most grocery stores), peanut oil is the choice of home fryers as well as chains such as Five Guys Burgers and Fries.
