The Best Cajun Sweet Potato Fries Recipe Will Make You Scream “Fry-YAY!”

Fries are one of those foods I cannot live without. And it’s not just because I love potatoes (trust me, I really, really love potatoes).

It’s because fries are oh-so-tasty and can be served with practically everything. I mean, when you order a hamburger or a sandwich, is it really complete without that side of deep-fried strips of perfection?

When you order a milkshake, it is really as tasty without a side of crispy, salty spuds?

That last one might just be a me thing, but you have to believe me when I tell you that fries and milkshakes go together like peanut butter and jelly. If you haven’t ever dipped a fry in a milkshake, I demand that you go and do so immediately.

Seriously, stop reading this post and go right now!

When you take two amazing things and put them together, it’s like heaven on a plate.

This is true of many different flavor mash-ups, but it’s especially true when there is a combination of spicy and sweet in the same mouthful.

That is why this cajun sweet potato fry recipe truly stand out in a sea of fry recipes.

First, we are switching out the classic russet potato for a whole new root vegetable. To me, sweet potato fries are actually better than the classic French fry.

(Please don’t throw stones at me for saying that…)

I just love that subtle sweet flavor that works its way into every single bite. It’s a tiny burst of natural sweetness, on top of that classic savory flavor that you know and love.

While sweet potatoes are the star of this mouthwatering snack, the homemade seasoning with its punch of cajun flavor is an unbeatable and irreplaceable supporting actor.

When it comes to spicing things up for a recipe, I love turning to cajun flavors. Just like with these cajun tacos, the combination of savory and spicy seasoning really brings another level of flavor that you can’t get with many other spice combinations.

The best part is, the spices that you need for homemade cajun seasoning are already sitting in your spice rack. All you need is salt, paprika, onion and garlic powder, thyme, oregano, black pepper, and cayenne.

While these spices might seem humble as they sit on the shelf among your collection of canisters and jars, when combined you get an explosion or flavor that really makes this recipe stand out. It’s a spice mix that works just as well on salmon and chicken.

It’s the simplest snack to make, in addition to all the flavorful goodness that I just talked about.

There are three major points that you need to make sure that you do in order to prepare this recipe perfectly:

1. Cut Even Strips

You want to make sure that you are cutting them into even strips. This will ensure that the potatoes all cook at the same rate, and will get nice and crispy in the oven. Starting with similarly sized root veggies helps to ensure this.

2. Soak

Soaking the strips in cold water is very important, especially when you are baking fries. This step helps rinse off the excess starch, which makes the potatoes crisp up better in the oven.

Just make sure that you pat down those potatoes thoroughly after rinsing so they are dry before coating in oil and spices.

3. Use the Right Pan

The key is not to overcrowd the pan, and you want to be sure to use a large, rimmed baking sheet (two if you have to). You want all of your fries to bake in an even layer, so make sure none of them overlap. That way they will come out crispy.

Now you are ready to conquer this recipe!

Cooking by the Numbers…

Step 1 – Measure All Ingredients and Prepare Sweet Potatoes

Measure out all of the ingredients as listed in the ingredients list. Wash the root vegetables well, get out your vegetable peeler, and get to work.

Cut each sweet potato into thin strips that are about ¼ inch thick. The most important thing for this step is to make sure they are all uniform in thickness.

Add the strips to a large bowl. Fill the bowl with cold water and let soak for 30 minutes. Rinse with cool water, then drain the potatoes and pat dry with paper towels.

Dry the bowl, and put the strips back in. You could use another bowl instead, but this helps to save on dishes!

Step 2 – Season

Preheat your oven to 425˚F. Use 1 tablespoon vegetable oil to coat a large rimmed baking sheet.

Add the rest of the oil, 1 teaspoon salt, and the remaining spices to the bowl. Toss with tongs until the root veggie strips are evenly coated.

Spread the strips in an even layer on the prepared baking sheet. Be careful not to crowd the pan, or they won’t crisp up the way you want them to. Feel free to use two pans if you like!

Step 3 – Bake

Bake for 25 minutes. Toss halfway through the baking process. The sweet potatoes will be cooked through and slightly golden on the edges when they are done.

Transfer them to a large bowl once cooked through. It’s fine to wipe out and use the same bowl again! Toss with 1 teaspoon salt to season, and serve immediately.

What Sauces Can I Dip These Fries In?

When it comes to serving fries, I am a huge advocate of providing a variety of sauces to dip them in.

My personal favorite for this particular recipe is the classic ketchup. If you’d like to change things up, you can whip up a creamy garlic aioli. Other options include Dijon mustard, ranch dressing, fry sauce (a combination of ketchup and mayonnaise), straight up mayonnaise, or even cheese sauce.

Are you exhibiting symptoms of fry fever? If you are in the mood for something different than the classic russet, check out these recipes:

  1. I can see why you had to make these! I love that combination of smoky spice from the cajun flavours and the sweet potato. Can’t wait to try these : )

  2. I’m so thankful for the friendships I’ve made through the world wide web. Spicy, oven-baked sweet potato fries are dinner more often than I’d like to admit. I’ll never get tired of them!

  3. i LOVE making sweet potato fries, but mine don’t look as pretty as yours! will be giving this recipe a try soon – love the flavor profile here!

  4. Yep. I’m making these tomorrow! Can I tell you how happy your blog makes me? Very happy : ) And, I love the new changes too!

  5. Oh deliciousness! I have sweet potatoes, and every other ingredient (except for coconut oil – would olive be okay?) so these will be appearing on our dinner table sometime this week. What a pity I am one of the only people who likes sweet potatoes in our family….

  6. These look (& sound!) amazing. Maybe a little spice will trick my brain into thinking I am in a warm climate instead of the current blizzard conditions! 🙂

  7. These were so good! Not being a fan of Cumin, I just added a bit. I kicked it up by adding a little Chipolte Chilli Powder in addition to regular Chili powder… I need to start using my Coconut Oil more, Thanks!
