This is a simple recipe for amazing oven baked sweet potato fries. It’s a great side dish that everyone loves – kids and adults. Very quick to put together and we’ll use common ingredients that you most likely already have on hand.

I love sweet potatoes! I grow my own sweet potatoes every year, but considering the fact that I live in North Carolina – the Capital of the Sweet Potato, crates of sweet potatoes that aren’t from my own garden usually find their way to my front porch in the summer. 

We have so many sweet potato growers around here.

It seems like often they are left with a lot of sweet potatoes and those find their way to the Christian centers in town. These centers just hand them out to whoever wants sweet potatoes. 

I am never up to date on local (or any other kind of…) news so I have no clue when those parties are happening, but I have the best neighbors a person can ask for and they just pick up some for me and the kids and bring them over.

Sometimes I come home to find a crate of sweet potatoes or onions or something else on my front porch, it’s so helpful and so heartwarming!

Even though I usually get free sweet potatoes during the season, I still grow sweet potatoes myself.

I love the plant! I love the beautiful flowers, I love how it’s crawling everywhere, I love how strong it is — there are no pests to deal with! And, of course, we all (the kids and I) love the digging and harvesting of the potatoes

Aside from the common orange sweet potatoes, I also grow purple sweet potatoes but I don’t roast them the same way as I’ll show you here. Roasted purple sweet potatoes are done a bit differently.

So you can imagine that between the ones I grow and the ones I get I end up with a ton of sweet potatoes in late summer, and I am not complaining!

There are so many amazing dishes with sweet potatoes, one of my favorites is this simple oven-baked sweet potato fries (my other favorite is my sweet potato bread. I freeze a lot of mashed sweet potatoes for it). 

Let’s get started with this delicious oven-baked sweet potato fries!

Tools That We Are Going to Need…

Let’s gather everything that we need…

Cutting board – I always use my wooden one for cutting vegetables.

Knife – to cut the potatoes into fries.

Small bowl – to mix the sauce in.

Large bowl – to mix the sauce and the sweet potato fries.

Baking sheet – to bake the fries on.

Parchment paper – to make clean up much much easier!

That’s it. We are ready to make oven baked sweet potato fries.

Homemade Sauce for Sweet Potato Fries…

Adding all the ingredients of the sauce.

To a small bowl, add 4 tablespoons of olive oil, 2 tablespoons of mayo, 1 tablespoon ketchup (if you want a little spice you can add hot sauce instead of the ketchup or do half a tablespoon ketchup and half hot sauce), 1 teaspoon black pepper, 1 teaspoon paprika, and salt to taste. 

This is all we (my mama and I were cooking together) put there this time, but you can also add some garlic powder or even some cumin if you like, they are a great addition as well. 

Mixing the sauce ingredients.

Give this a good mix and set aside.

Prepare the Sweet Potatoes…

Next (sorry that I am missing a couple of pictures here…), wash two large sweet potatoes well.

Cut off the ends but do not peel the sweet potatoes. Then, cut the potatoes into 1/4 inch wide, long strips. 

The peel adds to the crunchiness of the fries. It’s very tasty and very healthy, so there is no reason to remove it. Just make sure you wash the potatoes well and dry them well before you start slicing them into fry strips. 

Baking Sweet Potatoes Fries…

Adding the sweet potato fries to the sauce.

Put your potato slices into a large mixing bowl and add the sauce on top of them. Then give the fries a good mix to coat all of the strips with the sauce. 

Spreading the sweet potato fries on a baking sheet.

Preheat your oven to 400 degrees Fahrenheit.

Line a baking sheet with parchment paper and spread the potatoes in one layer on the baking sheet. Place in the preheated oven and bake for 20 minutes or so.

I always check my fries after 20 minutes because my oven is a bit old and it seems to bake everything better from the bottom and not so much on top. If your oven is more even than mine, you can probably just leave the fries as they are on the baking sheet and give them a bit more time (like 10 more minutes or so). 

Since my oven is not a great one, I usually use a spatula to flip the fries then I place them in the oven for an additional 10 minutes.

And that’s it! 

You can play a bit with the time. If you like them drier and crispier you can leave them in the oven for a few more minutes, if you like them a bit softer you can remove them from the oven. 

Serving Oven-Baked Sweet Potato Fries…

Serving oven baked sweet potato fries.

Let the fries cool for a couple of minutes before you transfer them to a bowl. Spread with a bit more salt and enjoy while they are still hot!

We eat them as a side to a sandwich or a hamburger.

They can be a side for any fish dish or a stake or so many other meat dishes.

Oven-baked sweet potatoes are easy to make. The chance of you having any leftovers is very small, but if you happened to have leftovers you can heat them in the oven the next day.

I hope that you’ll give this simple recipe a try! You are going to love it!
