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.

How to make crispy sweet potato fries.

To make the perfect crispy sweet potato fries, every time, follow these easy tips.

The size of the fries matters!Sweet potatoes cut into fries

Be sure to cut the sweet potato into smallish fries. I cut mine about 1/4-3/8″ 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 firstSoak the sweet potatoes

Soaking the sweet potatoes in cold water for about an hour before cooking them 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.

Arrowroot helps to crisp the fries.Add arrowroot to the sweet potatoes

Before I add the olive oil, I place the sweet potato fries in a large bowl and add 2 tsp of arrowroot powder . Everything gets a good stir to make sure they are well coated. Doing this helps the sweet potatoes to crisp up when cooked. (Cornstarch also works if you can eat gluten.)

Season wellseasonings for sweet potato fries

I use olive oil, pepper and paprika for my crispy sweet potato fries: (This amount is good for two large sized sweet potatoes.)

  • 2 tbsp olive oil
  • 1/4 tsp black pepper
  • 1/2 tsp smokey paprika

Now add the olive oil to the bowl and give the fries another shake.  Sprinkle over the seasonings and mix well. Now they are ready for the baking sheet.season the sweet potato fries

Even spacing means even cooking!Lay out the sweet potato fries

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 425 º F oven for about 30-40 minutes on the top shelf of the oven. (depends on the size of the fries.) Flip them half way through to ensure that they cook well on both sides.Crispy sweet potato fries and sauce

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.

Hold the salt!

You will notice that my sweet potato seasoning 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 home made paper conesweet potato fries in a 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.eating some sweet potato fries

You may think I am nuts but, for me, a sweet potato, cut into the shape of French fries, seasoned and then baked to crispy perfection is the best snack ever. Because they’re baked and not fried I feel good about eating them whenever I get a yen for a snack. I’m all for guilt-free indulgences, aren’t you?

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 a almost as good a job of crisping them as does soaking them first. (almost is not quite but good when you are in a time crunch!)
