I have a confession.

I am not only addicted to desserts; I have a serious obsession with sweet potato fries.  Well, if we’re being honest – I have an obsession with ALL things sweet potato.  Baked sweet potato wedges, sweet potato casserole, sweet potato chips, sweet potato chili, and my mom’s brown sugar glazed sweet potatoes. (<- my favorite thanksgiving side dish.)

I make baked sweet potato fries at home all the time.  Since they’re baked and not fried, I feel good about snacking on them or serving them up with dinner.  The “recipe” is so simple, I never thought to share it on my blog. But the time has come; I can no longer keep my love for these cinnamon-spiced fries a secret.

{polish: Essie “For the Twill of It”}

The first step is to start with some sweet potatoes. The amount of potatoes depends on how many fries you want to make.  For the two of us, I always use 2 very large sweet potatoes. Sometimes three, which makes a ton of fries.  I’ve never complained about snacking on the extra sweet potato fries, that’s for sure.

If you’re baking for just yourself, I’d use 1 large sweet potato.  If you’re making the fries as a side dish for a family of 4+, I’d use 1 small size sweet potato per person depending how hungry you are.

Wash, peel, and chop the sweet potatoes up into french fry shapes with a very, very sharp knife.  When I first started making these fries at home, the shapes of my fries were all over the place. I didn’t cut them very neatly at all. But I’ve picked up on french fry shaping; it takes practice.  They all won’t be perfect.

I like to cut the fries to be a little thin.  Not shoestring-style and not too thick. About 1/4 inch wide. Like so:

Here’s a trick I’ve learned over the years:  toss your fries into a touch of cornstarch right after you slice them. This creates a very thin layer of coating and help the fries get crispy in the oven. To coat, toss the fries and cornstarch in a large bowl or throw both into a large ziplock bag and shake shake shake.  The second option is obviously more fun.  You want cornstarch to go onto the fries before the oil and the spices or else your fries will have large white lumps and taste like cornstarch.

After they’re coated with cornstarch, sprinkle with a touch of olive oil (or coconut oil) and cinnamon-sugar. The oil will help your fries crisp up in the oven.

Instead of coating in cinnamon-sugar, sometimes I sprinkle the fries with a touch of salt and cayenne pepper. Or just simply sprinkle with salt. The spice is totally up to you and what you like.

Line the fries up on a Silpat or parchment paper lined cookie sheet.  Try not to crowd them and make sure they have a bit of space in between each other.  The less fries on the pan, the better.  Too many fries shoved together and they’ll just steam – not bake.

Bake for 15 minutes at 400F degrees.  Remove from the oven and flip them over. Bake for another 10-15 minutes.  Make sure to rotate your pan during the bake times or else you may get some burnt ends.  My oven has hot spots, so I always make sure to rotate the pan.

Here’s another trick that I learned after making my baked apple chips.  Turn the oven off completely and crack open.  Keep the baked sweet potato fries inside and allow to sit there for about 30+ minutes.  Sitting in the oven as it cools down, rather than sitting at room temperature, will help your fries get crispier.  The crispier, the better in my opinion!

Obviously you may not have time for that step, so it’s not mandatory.  But I try to plan ahead so I have time. No matter what you do though, some fries will still be soft. There is just no way around it with sweet potatoes because of their moisture content.  Using a couple of these tricks certainly helps in the crisp factor though.

Now it’s time to gobble them up. ;)

I love making these because sweet potatoes are (1) cheap (2) readily available year-round (3) nutritious (4) don’t spoil quickly (5) easy (6) delicious.

The second I was finished with this photoshoot, I downed the fries in minutes. I honestly don’t even think I took a breath of air. I could live on sweet potato fries for the rest of my life. I love their crispy ends and soft centers!

Depending on how you coated your fries, you can dip them in anything you’d like.  I like to dip my salt/spicy cayenne fries into ketchup. And for my cinnamon-sugar fries? I like them plain.  They have so much flavor is as, you really don’t need a dip!

PS: Do you know about my addiction to ketchup??? You guys, it’s embarrassingly bad. My family calls me the condiment queen. I’ll have a side of fries with my ketchup, thankyouverymuch.

PPS: Did you know that 1 sweet potato contains over twice the amount of vitamin A you need for the day?  Yeah.  And trust me, it’s easy to eat more than one sweet potato worth of these fries!

Baked Sweet Potato Fries

Crispy edges, soft centers, nutritious and delicious. Baked, not fried - so you can feel good about eating them!

Prep Time: 15 minutes

Total Time: 45 minutes, plus cooling

Ingredients:

  • Sweet potatoes - 1 per person
  • 2 teaspoons of cornstarch per large potato
  • 1 Tablespoon of olive oil (or coconut oil) per large potato
  • cinnamon-sugar or salt, cayenne, curry, pumpkin pie spice, garlic - anything you please

Directions:

Preheat oven to 400F degrees. Line a large baking sheet with parchment paper or a silicone baking mat.  2 large sliced potatoes are usually too crowded on 1 sheet, but it depends on their size.  You may need an additional sheet. Set aside.

Wash and peel the potatoes. Cut off the ends. With a *very* sharp knife, cut the potatoes into thin slices about 1/4 inch wide.  Place in a large bowl or ziplock bag and toss with cornstarch. You want a nice thin coating.  Pour the potatoes into a strainer to get rid of any extra cornstarch.  Discard the extra cornstarch out of the mixing bowl too. Place potatoes back into the bowl and add the olive oil and seasoning(s) of choice.

Line the sweet potatoes onto the baking sheet.  Try not to crowd them or else they won't bake, they'll just steam.  Bake for 15 minutes.  Remove from the oven and flip. Place back into the oven for 10-15 more minutes. Make sure to rotate the pan to avoid uneven browning.  Don’t fret if the edges are a little brown, they will taste more caramelized than burnt.

Turn the oven off and keep the fries inside as the oven cools down for about 30 minutes. This step will help the fries get crispier. Enjoy immediately.

    I just made these awesome fries and wanted to thank you for your tip on leaving them in the oven for 30 minutes! I’ve tried them before with no luck. I can tell you that I’m eating them right out of the oven and they are delicious! I’m on a special diet so wasn’t able to use the cornstarch. I used EVOO and sea salt. Then decided to try a little cinnamon. They are incredible. Congratulations on your cookbook – I look forward to seeing it.

    HOOOLY SMOKES. So I have loved sweet potato fries ever since I had them at applebees a few years ago and I just made these. MAN ARE THEY DELICIOUS!! I didn’t add any sugar, since I like my food with as little sugar as possible, and made them with just cinnamon. They made my house smell amazing and they taste JUST the way I want them too. Oh my gosh..thanks so much!

      Erika, one of my favorite things about baking is sharing. I grew up with my grandma and mom who both loved sharing their goodies and I picked up on it. I love to bake for others and hope to open a bakery someday. So while I do test all of the recipes coming out of my kitchen, I like to share them with test tasters, neighbors, family, etc. But some recipes I hoard for myself, like all the healthy stuff!

    One trick that’s getting me there is soaking the potatoes after cutting them up. Have you tried that? It makes a big difference! Your version already looks perfect, though. :)

    Reply

    • Sallyreplied on November 18th, 2013 at 7:48 pm

      You may cut them up the night before and bake the following evening. You could also bake them all the way through and then reheat, but they won’t be as crispy. You could also make them, freeze them, then warm them back up in the oven. But in order to preserve the crispiness AND make ahead, I suggest just cutting the sweet potatoes one day and baking the next day.

For the corn allergy… I’ve never tried arrowroot instead of the cornstarch, but I suspect it to work out just fine. I have had a few readers use flour instead (using a very light coating). I have never tried either option, but if you do – let me know.
