These Cajun Fries are perfectly seasoned and extra crispy, with the most delicious spicy kick! They’re a favorite side dish for burgers, sandwiches, chicken and more!

These Cajun fries are a delicious variation of my Baked French Fries recipe, kicked up a notch! Flavorful Cajun spices make crispy French fries even more irresistible.

Making these Cajun fries is quick and easy, using either my homemade Cajun Seasoning or a store-bought spice blend. The hardest part is waiting for them to finish baking. Once the hot fries come out of the oven, they rarely make it onto our plates. We usually find ourselves eating most of them straight from the baking sheet!

Serve your Cajun fries with Turkey Burgers, Black Bean Burgers, Baked Chicken Thighs or Air Fryer Grilled Cheese. They are sure to hit the spot!

Cajun Fries Recipe Ingredients

Ingredients for cajun fries recipe.

You’ll need just a few ingredients to make these fantastically flavorful Cajun fries.

  • Russet Potatoes: Russet potatoes make the best homemade French fries that are crispy on the edges and fluffy in the centers. 
  • Oil: Use either olive oil or canola oil. The oil helps the seasonings to stick to the fries and also helps them to crisp up in the oven.
  • Cajun Seasoning: I’ve included the individual spice amounts that you’ll need in the recipe notes below. But if you’re going to measure out the seasonings to make these fries, you might as well make a batch of my homemade Cajun Seasoning. It can be used to make Cajun Chicken Pasta or to season baked chicken breasts, roasted cauliflower and more.
  • Salt: My homemade Cajun seasoning has some salt in it, so we need to add just 1/4 teaspoon more to make the flavors pop. If you use a store-bought seasoning, you can adjust the amount of added salt, depending on how much salt is in your seasoning blend.

How to Make Cajun Fries

Here’s an overview of the simple steps to making this recipe. Find the full printable recipe with ingredient amounts and instructions in the recipe card below.

  1. Scrub the potatoes and pat them dry. Then cut them into 3/8-inch thick French fries. Cutting potatoes into fries.
  2. Soak the fries in cold water for 15 minutes. Fries soaking in bowl of water.
  3. Dry the fries really well with a clean kitchen towel or paper towels. Rinse and dry the soaking bowl and then place the fries back in it. Drying fries with paper towels.
  4. Drizzle oil over the fries and toss to evenly coat them.
  5. Sprinkle on the seasonings and toss to evenly coat the fries. Fries in bowl with seasonings.
  6. Arrange the fries in a single layer on a parchment paper lined baking sheet. Unbaked fries in a single layer on baking sheet.
  7. Bake at 425° F for 27-31 minutes, until golden brown and crispy.

Recipe Tips

  • Don’t peel the potatoes. The skins make the fries crispier.
  • Soaking the potatoes in cold water for 15 minutes helps to remove excess potato starch, giving you crispier fries. But if you’re really short on time, you can skip the soak and the fries will still be delicious. After soaking, be sure to dry the fries completely.
  • Don’t crowd the baking sheet. The fries need a bit of space in between them for air to circulate and make them crispy.
  • Bake the fries until they are browned on the ends. A few extra minutes can make all the difference in crispiness. My fries took the full bake time.
  • This recipe serves 2 generously or makes 4 smaller servings.
  • Try this recipe with sweet potatoes! Cajun seasoning is delicious on Sweet Potato Fries. If using sweet potatoes, the fries may be done a few minutes early.

Can I Cook Cajun Fries in the Air Fryer?

Yes! Just like my Air Fryer French Fries, you can air fry these Cajun fries at 380° F for 14-18 minutes, tossing to flip the fries after 8 minutes. For best results, preheat your air fryer for 5 minutes before adding the fries to the basket and air fry a single layer of fries at a time.

Serving Suggestions

Enjoy these Cajun fries as is, or dip them in ketchup, ranch dressing, BBQ sauce, fry sauce, aioli, or even a milkshake!

Crispy and incredibly flavorful, these Cajun Fries have the best spicy kick! Serve them with burgers, grilled cheese sandwiches, baked chicken and more!


  • 2 medium Russet potatoes, unpeeled
  • 2 tablespoons olive oil, or canola oil
  • 2 teaspoons Cajun seasoning, see note below for individual spices*
  • ¼ teaspoon salt


  • Scrub the potatoes and pat them dry. Slice into 3/8-inch thick French fries by first slicing potatoes into 3/8-inch thick slices and then cutting each slice into 3/8-inch thick fries.
  • Place the fries into a bowl, fill with cold water to cover the fries, and let soak for 15 minutes.
  • Preheat oven to 425° F. Line a rimmed baking sheet with parchment paper.
  • Take the fries out of the water and dry them very well with a clean kitchen towel or paper towels. Rinse out the soaking bowl and dry it well. Place dry fries back in the bowl.
  • Drizzle the olive oil over the fries and toss to evenly coat. Sprinkle with the Cajun seasoning and salt (or use the individual spices listed in the note below). Toss to evenly coat the potatoes with the seasonings.
  • Arrange the potatoes in a single layer on the parchment lined baking sheet with a bit of room in between each French fry. This helps them to crisp up as they cook.
  • Bake for 27-31 minutes, until golden brown and crispy.


  • Instead of the 2 teaspoons Cajun seasoning and 1/4 teaspoon salt, you can use: 1 teaspoon paprika, 1/2 teaspoon garlic powder, 1/2 teaspoon dried oregano, 1/4 teaspoon onion powder, 1/4 teaspoon dried thyme, 1/2 teaspoon salt, 1/4 teaspoon black pepper and a 1/8 teaspoon of cayenne pepper (for moderately spicy, adjust the cayenne to your tastes).
  • To cook in an air fryer: Preheat air fryer to 380° F for 5 minutes. Arrange fries in a single layer in air fryer basket. Air fry at 380° F for 14-18 minutes, tossing to flip the fries after 8 minutes.
