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.

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 Double-Fry Method

The first round is at a lower temperature to cook the inside of the potato and the second time you'll use a higher temperature to make the fries golden brown and crispy. You can use a home deep-fryer or just heat the oil in a Dutch oven.

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 ).

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.

It's not so much the oil as it is the process. The best fries are very dry when the go in for their first fry, then when they go in for the second time, they really crisp up. You can use any oil with a high smoke point, sun flower oil is my favorite and peanut oil is great, too.

Canola Oil: Best All-Purpose Oil for Frying

It's great for all different kinds of frying methods, but it is also a good choice for roasting vegetables or making dressing. At about 400 degrees, the smoke point of canola oil is fine for deep-frying—a lot of deep-fried foods need an oil temperature of 325 to 375 degrees.

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.

The baking soda is clutch, as it alkalizes the water/potatoes and contributes to the crunch effect. The salt goes both in the water and on the potatoes for maximum seasoning. A big glug of olive oil makes them super crunchy and that fat gives the super high heat something to work with.

The key to the perfect chip, is to use a floury potato like King Edward or Maris Piper, and ensure they're cut into evenly sized, uniform fries. This means you'll get evenly cooked chips at the end with a crispy outer shell, but a soft and fluffy centre, rather than the half frazzled, and half undercooked.

How long should I 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.

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 longer and slower you cook a sweet potato, the more maltose is formed and the sweeter it will taste. So if you want a much less sweet potato try steaming it, or cut it into small pieces and roast on a higher heat.

They're high in fiber and antioxidants, which protect your body from free radical damage and promote a healthy gut and brain. They're also incredibly rich in beta carotene, which is converted to vitamin A to support good vision and your immune system.

Don't overcrowd the baking sheet!

This is an important one! If the baking sheet it too crowded, the sweet potatoes will not crisp. You should provide optimal space for air to flow through, and the sweet potatoes shouldn't be touching.

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.
