What time is it? It’s CRISPY BAKED SWEET POTATO FRIES TIME!!!

I didn’t grow up eating a ton of sweet potatoes, other than sweet potato casserole at Thanksgiving, but once we went gluten free, sweet potatoes became a regular part of our diet. And I LOVE THEM.

We eat them all kinds of ways–stuffed, mashed, roasted, and so much more. But crispy oven sweet potato fries are one of our absolute favorites. We have these a few times a month because they’re always such a win.

I love that baked sweet potato fries go with so many different main dishes (see the gray box below for some of our faves!), and our favorite fry seasoning can be kept on hand for extra batches whenever the mood strikes.

Sometimes, sweet potato fries just don’t get *quite* as crisp as you want them, but I’ve figured out a few secrets that make AMAZINGLY crisp baked sweet potato fries every time.

I’m ready to spill all my sweet potato secrets with you, so here’s all you need to get started…

Crispy Baked Sweet Potato Fries with Fry Seasoning

Here’s What You Need To Make Amazing Baked Sweet Potato Fries:

  • First Up: Our Favorite Sweet Potato Fry Seasoning. I’ve tweaked my sweet potato fry seasoning over the years and settled on a mix of pantry staples that give me smoky, savory, delicious flavor every time. I’ve intentionally written the recipe big enough to help you keep a little stash of seasoning on hand so it’s easy to whip up a batch of these baked sweet potato fries any time.
  • Sweet Potatoes. Next up, you’ll (obviously) need sweet potatoes! I love red garnet sweet potatoes because of their deep orange color and gorgeous texture. Cut them into 1/2″ inch thick sticks for even cooking.
  • Olive oil. I love the flavor good olive oil adds to oven sweet potato fries. Our go-to is Queen Creek Olive Mill’s balanced oil for its amazing flavor. (Not sponsored, just a small business shout-out to a brand I love!)
  • Arrowroot or Cornstarch. If you can, add cornstarch (gluten-free) or arrowroot (paleo, whole30) to your baked sweet potato fries to help them develop a really nice crisp coating. Speaking of crisp, here are our secrets for the best CRISPY sweet potato fries…

6 Tricks For The Best Crispy Sweet Potato Fries:

How To Get Crispy Oven Sweet Potato Fries:

  1. Leave the skins on! The skins get crispier than the orange flesh of the sweet potatoes, so I recommend leaving the skins on when you can, since they’ll develop that crispy outer coating.
  2. Cut them evenly so they cook evenly. I recommend cutting your sweet potato fries into 1/2″ thick sticks. The more evenly you cut the sweet potato fries, the more evenly they’ll cook, so really take your time to get this right.
  3. Add arrowroot or cornstarch. If it works for your dietary needs, adding some cornstarch (gluten-free) or arrowroot (paleo) can help create an outer coating on the fries that’ll crisp up when baked.
  4. Spread them out in a single layer for more air circulation. If oven sweet potato fries are packed too tightly, they can steam instead of roast. Try not to let them overlap or touch too much when baking. The more careful you are about this, the more crispy they’ll get.
  5. Keep That Temperature Up & Flip Regularly. A higher temperature can really help crisp up the skin and the starch layer. You’ll want to cook your fries on the center rack of the oven and flip them every 10 minutes for even browning.
  6. Eat Them Hot! Lastly, baked sweet potato fries will start to soften once they’re out of the oven, so the sooner you can enjoy them, the better!

What’s The Best Way To Re-heat Sweet Potato Fries To Make Them Crispy? Honestly? Popping them in the air fryer for a few minutes (5-8 min) at 400 degrees F. But, if you don’t have an air fryer, putting them on a greased sheet pan in the oven for 5-10 minutes at 400 degrees F. will help crisp them up again.

Let’s Talk Dipping Sauces! Here Are The Best Dipping Sauces For Sweet Potato Fries:

Ketchup. (Duh.) Okay, not breaking any stereotypes here, but ketchup is a classic (and tasty!) dipping sauce for sweet potato oven fries. If you’re paleo, be sure to use a paleo-approved ketchup, like this one.

Chipotle Dipping Sauce. Just tossing this out here because it’s delicious. If you like a bit of smoky kick with your crispy sweet potato fries, try our creamy chipotle ranch. It’s gluten-free, paleo & vegan friendly and tastes AMAZING.

BBQ Ranch. If smoky BBQ flavors are your jam, try our BBQ ranch. It can really hit the spot!

Pineapple Relish. Stay with me! One of our favorite local restaurants serves their sweet potato fries with the MOST amazing pineapple relish. It’s sweet, tangy, and a bit unexpected in all the best ways. We re-created their recipe the best we could a few years ago, and it’s really yummy every once in a while!

Fry Sauce. If you love classic fry sauce from chain restaurants, you might love this Paleo & Whole30 Chick Fil-A sauce copycat or this popular fry sauce recipe.

  2. Whisk to combine or cover the jar with a lid and shake to combine well.
  3. Store fry seasoning in an airtight jar or container with a lid up to 1 year. (This recipe makes enough for several batches of fries)

  4. Spread seasoned sweet potato wedges out on a baking sheet in a single layer, trying not to overlap the potatoes.

Notes

Tips For Crispy Sweet Potatoes:

  • Leave the skins on! The skins get crispier than the orange flesh of the sweet potatoes, so I recommend leaving the skins on when you can, since they’ll develop that crispy outer coating.
  • Add arrowroot or cornstarch. If it works for your dietary needs, adding some cornstarch (gluten-free) or arrowroot (paleo) can help create an outer coating on the fries that’ll crisp up when baked.
  • Spread them out in a single layer for more air circulation. If sweet potato fries are packed too tightly, they can steam instead of roast. Try not to let them overlap or touch too much when baking. Use two baking sheets, if you need to!
  • Keep That Temperature Up. A higher temperature can really help crisp up the skin and the starch layer
  • Eat Them Hot! Sweet potatoes are their crispiest fresh from the oven. If you can scoop them straight from the baking sheet onto your plate, they’ll be at their best!

  1. Great recipe! I will keep some of this seasoning on hand for sweet potatoes from now on. Even if I do not have time to cut into fries it adds so much flavor. The fries are pretty fun though!

    1. I haven’t done them in the air fryer, but yes, I think so! Just make sure to shake them regularly so they don’t steam. The more they’re spaced out, the better they’ll crisp!
