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.

These orange spuds are exploding with antioxidant-rich vitamin A and also contain equally hefty doses of fiber and potassium. Sweet potatoes contain about 15 grams more carbohydrates per serving, but that's no reason to pass on these tubers; they can also make super-tasty and healthy baked fries.

If you'd like, you can soak the sweet potato slices for 30 minutes up to 2 hours before frying to remove excess starch.

Simmering the fries in water washes away the excess sugars that can cause the fries to brown too much before they have a chance to properly crisp up when frying. The water also activates the starches in the potato. Starch, when fried, is what creates that crispy surface we want!

The secret to crispy on the outside/fluffy on the inside is to cook them twice. Use russet (starchy) potatoes. Cut your fries and put them in an ice water bath to rinse off excess starch and prevent them from turning brown while you finish cutting. Try to keep the fries uniform in size so they cook evenly.

The Bottom Line. 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.

So if you want a sweet, sweet potato, you have to cook it until it reaches 135–170°F (57–77°C). And you want to keep sweet potatoes in that range for as long as possible. That will maximize how sweet the potatoes taste.

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.

While it may seem like a pain, soaking the potatoes in hot water for 10 minutes prior to cooking them in the air fryer is essential. The water removes excess starch, allowing the fries to be their crispiest. Instead of soaking them in large bowl of cold water, I like to use hot water to cook the potatoes slightly.

Why do my air fryer sweet potato fries turn black? Sweet potatoes contain a higher concentration of sugar than standard potatoes, and caramelize as they cook in the air fryer. If you find the fries are darkening too quickly or deeply, cook at a lower temperature, or for a shorter period of time.

Why are my homemade fries never crispy? ›

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.

My guess is you aren't blanching the sweet potato fries before you are frying them. In order to get crispy fries, of any type, you need to cook them twice. You begin by either boiling them in water, or frying them at 325, until they are just cooked through, but not so much that they lose their shape.

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.
