Sweet Potato Fries

Crispy Sweet Potato Fries! Yes, we are in full swing of fun summer recipes and today is no exception. These homemade sweet potato fries were one of the biggest hits at a recent Memorial Day BBQ party for 40 people (yes, Crispy Sweet Potato Fries for 40!) and it is all thanks to one secret ingredient!

I’m not sure if you’re like me, but I love sweet potato fries. I was introduced to them sort of late, being a purist and all. I couldn’t understand why anyone would mess with the perfect food, French Fries, long enough to make them out of a different potato. Then, one day I was at a burger place back in LA that offered 1/2 fries, 1/2 sweet potato fries. YES! All the adventure, 50% the commitment.

What’s Worse than Soggy Sweet Potato Fries?

The flip side to the delicious sweet potato fry movement is places like Lucille’s BBQ (which I love for almost their whole menu) who serve you a mountain of what you hope will be delicious sweet potato fries and instead you find…. soggy sweet potato fries. Imagine if you will the annoyed pregnant Sabrina craving these fries one day and finding them soggy. Poor waitress, it wasn’t even her fault and my reaction was… well, emotional. Haha, got to love pregnancy mood swings.

The secret to Crispy Sweet Potato Fries

Anyway, back to the task at hand! If you’ve ever wondered how to make sweet potato fries crispy, look no further. Crispy Sweet Potato Fries are COMPLETELY doable, and they’re easy in fact! Yes, they still need a second fry, but they don’t need a long soak! And I don’t even boil them ahead like I do with normal fries. Plus here’s the secret…. cornstarch!

Crispy Sweet Potato Fries with a single magic ingredient to keep them crispy! No more soggy fries, these stay crispy even if you have to reheat in the oven.

Ingredients

  • 2 sweet potatoes (about a pound)
  • 1/2 cup cornstarch
  • 6 tablespoons club soda (or cold water)
  • canola or vegetable oil for frying
  • Kosher salt to taste

Instructions

Note: click on times in the instructions to start a kitchen timer while cooking.

  1. Wash and peel your sweet potatoes. Cut into 1/4 - 1/2 inch thick fries, I usually stick closer to the 1/4 inch side.
  2. In a large colander, rinse the potatoes for about 10-15 seconds under cold water.
  3. Dry with paper towels or a clean dish cloth you don't mind turning slightly orange.
  4. Mix the cornstarch with the water to make a slurry in a large bowl or large ziploc bag.
  5. Add sweet potatoes and toss to coat.
  6. Heat your oil in your pot to 330-350 degrees. The hotter you make it the quicker they will cook, so if you went with the thicker cut, keep the heat a little lower.
  7. Add the fries 1 at a time so they don't stick together, but make sure you don't overcrowd your pan.
  8. Each time you do another round of potatoes toss the potatoes in the slurry again to prevent the cornstarch from settling. This should only take a few seconds and is even easier if you have a ziploc bag you can just flip upside down a few times and shake.
  9. Fry for 1-2 minutes (no browning yet) and drain on a brown paper bag.
  10. Once all the fries are done with their first dip in the oil, start the second round of frying.
  11. Fry them the second time for an additional 1-2 minutes, until they're browned and crispy.
  12. Season while hot with kosher salt and any other flavorings you want. Old bay seasoning is popular or even a cajun blend.
  13. If you're making ahead for a crowd, you can heat them in the oven at 325 degrees for 5-7 minutes to crisp them back up.

  1. My grandmother fried sweet potatoes but not cut as fries. The potato was sliced thin and fried then sugar was sprinkled on them

    1. Sorry this comment took so long to get to, it ended up in my spam filter somehow! If you freeze definitely do it after the first fry to avoid spoilage of the fry. It may need a slightly hotter oil to compensate for the much more severe drop in temperature too.

  2. I made these but ended up with some hard white little pebbles on the fries. I think the baking soda mixture made these hard pebbles. What did I do wrong? Thanks

    1. You can but they just won’t be crispy. If you leave them in the oil enough to get crispy then the inside won’t be fluffy and soft.
