Homemade baked spiced sweet potato fries are the perfect vegan/vegetarian side dish or snack. We've also included a tip below on how to make them extra crispy without frying! Low-fat but high-crisp? Count us in!

I call these "spiced" sweet potato fries instead of "spicy" because they don't have all that much heat. Instead, these baked beauties have a smoky/sweet/addictive flavor that I didn't know how to describe other than with the word "spiced".

While we love a solid hit of cayenne or red chili flakes on fries from time to time, the spice blend we developed for these taters is a bit more nuanced.

We combined smoked paprika, garlic and onion powders, and a touch of cayenne and chili powder to bring the right amount of heat without overpowering. As a result, you have delicious baked spiced sweet potato fries that still have some of that sweetness we love!

Since going vegetarian, my once dominant sweet tooth has significantly subsided. I crave salty foods more, and sweet potato fries my favorite way to satisfy the craving.

The truth is that I'll almost always order regular potato fries instead of sweet potato fries at a restaurant. However, these crispy, crunchy baked sweet potato fries are a favorite at home.

They're very easy to throw together, even if you don't have the exact right amount of spices. And if you're like me, you probably have leftover sweet potatoes hanging out, so these fries are a great way to avoid wasting them!

How to get actually crispy sweet potato fries without frying

When we posted a teaser of this sweet potato fry recipe last week on IG, a few of you inquired about crispiness. We won't deny that it's tough to make crispy baked sweet potato fries.

Sure, hot oil does things that an oven can't match. But, especially at home, who wants to load their dinner plate up with excess oils? That's why created this recipe for the crunchiest, crispiest baked sweet potato fries.

This took many trials. Rest assured that in our crowded kitchen, no trial sweet potato fry was wasted in the quest for crispness.

Finally we found that corn starch makes a big difference. You don't need much. We used about one tablespoon of cornstarch for this whole batch of sweet potato fries, and they were the crispiest baked fries we could hope for!

Recipe notes

Another note - we always sprinkle a hearty pinch of salt on our fries as soon as they come out of the oven. Salt can be a controversial subject, but we're firm believers that if you're eating a well-rounded, healthy-ish diet and preparing most of your food at home, you're probably doing just fine on salt intake.

If you have a health reason for limiting your salt intake, listen to your doctors, of course. For everyone else, don't fear little extra salt; it goes a long way when it comes to flavor.

Dips: I'll never turn down plain ol' ketchup, but I'm currently loving chipotle vegan mayo.

We also serve these crispy spiced sweet potato fries with smashed avocado seasoned with salt & lime. This vegan Herby Whipped Tofu Dip would also be quite yummy. However you dip your fries, we're sure the whole tray will disappear quickly. Enjoy!

    I haven't made this yet, but I can't wait to try it. I was in Arizona last year and bought some mesquite flour at a farmers market. I've been using it in anything I can think of. It adds a sweet, cinnamony, smoky flavor to food. The woman at the farmer's market made all sorts of gluten free, sugar free and vegan baked goods with it. There was a vegan, sugar free sour cherry muffin recipe I've been trying to duplicate without success so far. Please keep coming up with more recipes using this amazing flour!
