How to make crispy sweet potato fries
To make the perfect crispy sweet potato fries, every time, follow these easy tips.
If you have ever baked sweet potatoes, you will know that they end up “softer” than normal white baked potatoes, so making crispy sweet potato fries can be a bit of a challenge. There are a few things that you can do which will help to keep them crispy, not soggy.
The size of the fries matters!
Be sure to cut the sweet potato into smallish fries. I cut mine about ¼-⅜” thick. If you try to make them into steak fries, you’ll end up with a slightly cooked outside and soggy center.
Give them a water bath first
Soak the sweet potatoes in cold water for about an hour before cooking them. Doing this helps to crisp them up. Longer is fine too!
You can cut and soak them in the morning and they will be good to go later in the day. Just rinse them in cold water and pat dry on a clean towel before seasoning them.
Use arrowroot powder to make crispy fries
After you pat dry the sweet potato fries dry, add them to a large bowl with 2 teaspoons of arrowroot powder. Mix everything well, to make sure they are well coated.
Doing this helps the sweet potatoes to crisp up when cooked. If you don’t have arrowroot powder, you can also use cornstarch.
Season well
Once your sweet potato fries have an even coating of arrowroot powder, it’s time to season them.
I use olive oil, pepper and paprika for my crispy sweet potato fries: (This amount is good for two large sized sweet potatoes.)
- 2 tablespoons olive oil
- ¼ teaspoon black pepper
- ½ teaspoon smoked paprika
Space your fries evenly
Line a baking sheet with a silicone baking mat or parchment paper that has been sprayed with coconut oil spray. Place the sweet potato fries evenly on the cooking sheet.
Be sure not to crowd the fries to ensure even cooking. Even spacing means that the sweet potatoes will let the moisture escape from the fries and evaporate. If you crowd them, there will be too much steam and they will get soggy. If you want to double the recipe and have a lot of them to cook, use two baking sheets.
Time to bake
Bake the fries in a preheated oven at 425ºF for about 30-40 minutes (depending on the size of the fries) on the top shelf of the oven. Flip them half way through to ensure that they cook well on both sides.
Optional tip
When the cooking time is done, if they are still not quite as crispy as you want, turn off the oven and leave the fries in it for a bit longer to crisp up more without burning.
Salt the fries after cooking
You will notice that my sweet potato seasoning mix has no salt in it. This is because salt draws moisture out of the fries and creates steam in the oven, resulting in soggy fries. I just add sea salt and garlic salt after they are cooked!
Finishing up
Season with the garlic salt and pink sea salt and enjoy! I love to put them in a homemade paper cone.
These sweet potato fries are the ultimate comfort food indulgence without the guilt of deep frying. You can enjoy them often, guilt free! They are crispy, salty and so, so good for you! Your kids will love them! Serve them with my Whole30 Ranch Dressing for a Whole30 compliant snack.
Final tip:
If you are in a real hurry and cannot do the water bath, don’t worry. Adding the arrowroot or cornstarch to the fries does almost as good a job of crisping them as does soaking them first.
