Easy Sweet Potato Fries Recipe

These days, you’d be hard-pressed to walk into a sit-down restaurant and not find sweet potatoes on the menu in some shape or form. I’ve always wondered why fast-food joints haven’t jumped on the bandwagon, if only for the sheer order volume alone. It probably comes down to demand versus cost, but there’s no denying that sweet potato fries pack a much richer, more complex flavor than your classic french fry. Personally, I love roasting these babies in the oven for those crisp edges. The magic happens in the caramelization, a deep, sweet crunch you just can’t get from a greasy deep drying. Plus, lining the pan with foil means clean-up is over and done with in a flash.

Recipe Variations, Tips and Substitutions

Spices – You can use smoked paprika in place of chili powder. You could also use cayenne pepper for more heat.
Pan – You can bake these fries directly on the pan or line the pan with aluminum foil. I don’t use parchment paper for this dish as I want the potatoes to crisp.
Why Soak in Water? Soaking helps draw excess starch out of the sweet potatoes for a tender interior and crisp exterior.
What Does Cornstarch Do? Coating the sweet potato fries in cornstarch will help absorb some of the surface moisture lending a crispy texture to the fries. t’s one of those cooking secrets that really works.
Texture – Sweet potatoes roasted in the oven will crisp, but not be super crunchy the same as when fried in oil. The thinner you cut them, the more firm the texture will become when roasting.
Adjust Baking time According to Size – Adjust the roasting time based on how thick, or thin, you cut the sweet potatoes.
How to Know When They’re Done – Look at the color for caramelized edges, then pierce one of the thickest fries with a knife or fork to see if they’re tender.
Broil to Char – To crisp them further, turn the oven temperature to broil at the end of baking. Don’t walk away, sweet potatoes can burn, if not attended to.
Serving Options – Serve these fries straight from the oven with your favorite dipping sauces. We love comeback sauce, chick-fil-a sauce and yum yum sauce but, any will do.

Storage and Leftovers

Leftovers – Store baked Sweet Potatoes Fries chilled in the refrigerator for up to 2 days.
Reheating – Reheat in a preheated 375°F oven for 8-10 minutes or in a 350°F air fryer for a few minutes to crisp.
