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. Personally, though, going through this step didn't make a real difference for my fries. Peels on or off — it's up to you!

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.

Deep fried french fries are often double fried (once at a lower temp, once at a higher temp to crisp) I found out that the same thing works magically for oven fries! You can make oven french fries so good and crispy. Soak the potatoes in cold water after cutting for at least 30 minutes.

Give them a cold water bath: Once your fries are chopped, toss them into a large bowl. Then cover the fries completely with cold water and let them soak for at least 30 minutes (or up to overnight). This will help to rinse off the excess starch and help the potatoes crisp up beautifully in the oven.

Freeze Time for Sweeter Sweet Potatoes

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.

3. Do I need to soak sweet potatoes before baking? Many readers ask if they really need to soak the sweet potatoes before baking to get that great crunch. I've tried it both ways and found that soaking the sweet potato fries for about 30 minutes or so in plenty of cold water does help them crisp up a bit more.

This reaction causes food to brown when sugar reacts with amino acids under heat. So adding that sugar ensures that browning will occur, leading to that golden crisp exterior you want from a good french fry.

First let's talk about why cut potatoes need to be immersed in water to begin with. The reason is to prevent the potatoes exposure to air, which causes dehydration, oxidation, and discoloration.

How long should you soak potatoes for fries? ›

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.

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.

If you over-crowded the pan so that there isn't enough space for the potatoes to rest on the pan without touching each other, it will prevent the water from evaporating and making the potatoes crispy. You can always try to broil the potatoes for 1-2 minutes to crisp them up at the end of baking if necessary.

Sweet potatoes are not as starchy as russet potatoes, which yield best results when soaked in water before cooking to remove the starch from the surface area and cook to a crisp. Soaking sweet potato fries could produce steam in the air fryer, which could make the fries soggy.

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.

The secret to getting a crispy surface on home fries is to make sure the potatoes aren't warm when you pan-fry them. In this recipe, we precook the potatoes and let them cool to room temperature before they hit the buttered pan, ensuring perfectly crusty and crispy edges.
