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.

In my experience, soaking sweet potatoes doesn't make a huge difference in how crispy they turn out, so I personally skip this step to save myself the extra time and effort. To make crispier sweet potatoes, you can try my Air Fryer Sweet Potato Fries, which have a light coating that help them crisp up.

The cold water bath helps rinse the starch off the sweet potatoes so they're a bit more crispy. That said, if you do not have the time, you can still get crispy baked sweet potato fries by using high heat and a little drizzle of olive oil.

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.

"With very similar nutrient profiles and the fact that deep frying either type of potato essentially makes both equally unhealthy, there's no real health benefit to choosing sweet potato fries over regular ones," adds Willingham.

Baking powder can be used to achieve a crispy outer texture while keeping the inside of fried foods tender.

The broil setting on your oven cooks food quickly with direct heat—typically at 550°F (289°C)—and produces a seared finish that's similar to grilling. Smaller or countertop ovens usually preheat to the broiling temp faster, so you can quickly finish baked or slow-roasted dishes with crisp browned edges.

Why do my sweet potato fries turn out soggy in air fryer? ›

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.

Because of the natural sugar in a sweet potato, you will always get dark edges when roasting them in an air fryer. However, to keep them from burning, don't use a temperature that is above 380 degrees, and be sure to toss them well halfway through the cook time.

I've found that sweet potatoes really need space for a truly roasted, crisped-edge result. Aim for about one inch of space between pieces. This leads to good, dry, hot airflow that will let the potato pieces' moisture evaporate while letting them dry and crisp up more.

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.

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.
