I can’t stop thinking about these Popeyes-style Cajun fries, with a crispy golden shell and an irresistible sugary spicy crunch inside that keeps me coming back for more.

Jump to Recipe

And I am obsessed with Popeyes Cajun fries. I love how the crunch snaps at first bite, the spiced crust sticking to my fingers, the hint of granulated sugar that catches you when the heat hits.

I adore the contrast between craggy exterior and pillowy interior of those russet potatoes, each fry begging to be devoured. I reach for more like it’s instinct.

Messy and loud. Utterly addictive.

No pretense. No excuses.

Just salt, spice, and that sly sweet note that keeps me ordering, making, stealing fries off plates. I will never tire of them.

Worth every single, selfish bite.

Ingredients

Print Recipe (No Advertisments)

Russet potatoes: Basically the starchy base that gets crisp and fluffy inside.
Vegetable or peanut oil: Plus it’s the hot bath that makes fries crunchy.
All purpose flour: Helps form a light, crispy coating that sticks.
Cornstarch: Gives extra crunch and keeps coating from getting soggy.
Granulated sugar: Adds a subtle sweetness that balances the spice.
Sweet paprika: Brings color and a mellow, smoky red pepper warmth.
Cayenne pepper: Adds heat; use more if you like it spicy.
Garlic powder: Provides that savory, slightly roasted garlic pop.
Onion powder: Gives sweet, rounded onion flavor without texture.
Kosher salt: Brings out everything; it’s essential for proper seasoning.
Black pepper: Adds sharp, pungent bite and little peppery heat.
White pepper: Gives a cleaner heat that’s a bit earthy.
Dried thyme: Basically a herbal note, light and slightly lemony.
Ground oregano: Adds dried, savory Mediterranean herb depth.
MSG (optional): Plus it boosts savory umami; subtle, not weird.
Cold water: Helps the seasoning stick and clings to fries.

Ingredient Quantities

4 large russet potatoes, scrubbed (about 2 1/2 to 3 pounds)

4 cups vegetable oil or peanut oil for frying

1/2 cup all purpose flour

1/4 cup cornstarch

1 tablespoon granulated sugar

1 tablespoon sweet paprika

1 teaspoon cayenne pepper (use more or less to taste)

1 teaspoon garlic powder

1 teaspoon onion powder

1 teaspoon kosher salt

1 teaspoon freshly ground black pepper

1/2 teaspoon white pepper

1/2 teaspoon dried thyme, crushed a little

1/4 teaspoon ground oregano

1/2 teaspoon MSG (optional, for that authentic punch)

About 1/4 to 1/3 cup cold water (to help the seasoning stick)

How to Make this

Print Recipe (No Advertisments)

1. Cut the scrubbed russet potatoes into long matchsticks about 1/4 to 1/3 inch thick, rinse under cold water until the water runs clear to remove excess starch, then soak in cold water for at least 30 minutes or up to 2 hours, this helps them get super crisp.

2. While potatoes soak, mix the coating: whisk together 1/2 cup all purpose flour, 1/4 cup cornstarch, 1 tablespoon granulated sugar, 1 tablespoon sweet paprika, 1 teaspoon cayenne pepper, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1 teaspoon kosher salt, 1 teaspoon black pepper, 1/2 teaspoon white pepper, 1/2 teaspoon crushed dried thyme, 1/4 teaspoon ground oregano and 1/2 teaspoon MSG if using.

3. Drain and pat the fries completely dry with paper towels, you want them bone dry so the coating sticks and oil won’t spit.

4. Heat 4 cups vegetable or peanut oil in a deep pot or heavy dutch oven to about 325 F (use a candy or deep fry thermometer). Work in batches so oil temp doesn’t drop too low.

5. Fry the potatoes in batches for 3 to 4 minutes until they’re soft but not browned, remove with a slotted spoon and drain on paper towels; this first fry cooks them through.

6. When all batches are blanched and oil is back up to 375 F, fry the batches again for 2 to 3 minutes until golden brown and extra crisp, drain on a rack or paper towels briefly.

7. While fries are still very hot, put the seasoning mix in a large bowl, add about 1/4 to 1/3 cup cold water and stir quickly to make a slightly wet paste that will cling to the fries, you want it tacky not soupy, adjust water as needed.

8. Toss the hot fries in the seasoning paste a few handfuls at a time so they get evenly coated, work fast so the heat helps the mixture stick and form a slightly crunchy shell.

9. Taste and adjust: sprinkle a little extra salt or cayenne if you want it spicier, serve immediately for best crunch with your favorite dipping sauce, try ranch, ketchup, or spicy mayo.

10. Tips and hacks: don’t overcrowd the fryer or pot, keep oil temp steady with a thermometer, use peanut oil for better flavor and higher smoke point, double fry is the secret to crispiness, and if you want to make ahead, par fry, refrigerate on a tray then re-fry at 375 F before serving.

Crispy seasoned double fried russet fries written like a real person

Okay so here’s how I make the crispiest, most addictive fries you will probably ever eat. They take a little time but it’s worth it. I cut 4 big russets into long matchsticks about 1/4 to 1/3 inch thick. Rinse them under cold water until the water runs clear to get rid of extra starch, then soak the sticks in cold water for at least 30 minutes, up to two hours if you have time. That soaking is the secret to getting them super crisp.

While they soak, mix the coating. In a bowl whisk together 1/2 cup all purpose flour, 1/4 cup cornstarch, 1 tablespoon sugar, 1 tablespoon sweet paprika, 1 teaspoon cayenne pepper, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1 teaspoon kosher salt, 1 teaspoon black pepper, 1/2 teaspoon white pepper, 1/2 teaspoon crushed dried thyme, 1/4 teaspoon oregano, and 1/2 teaspoon MSG if you use it. It smells amazing.

Drain the fries and pat them bone dry with towels. Seriously dry them or the coating won’t stick and your oil will spit. Heat about 4 cups vegetable or peanut oil in a deep pot up to 325 F. Use a candy or deep fry thermometer so you can keep the temp steady. Work in batches so the oil temperature doesn’t drop too much.

Fry the potatoes in batches for 3 to 4 minutes until they are soft but not browned. Remove with a slotted spoon and let them drain on paper towels. This first fry cooks them through. When all batches are done and the oil is back up to 375 F, fry again for 2 to 3 minutes until golden and extra crisp. Drain on a rack or paper towels briefly.

While the fries are still very hot, put the seasoning mix in a large bowl and add about 1/4 to 1/3 cup cold water. Stir quickly to make a slightly wet paste that will cling to the fries. You want it tacky not soupy. Toss a few handfuls of hot fries in the paste at a time so they get evenly coated. Work fast so the heat helps the mixture stick and form a slightly crunchy shell.

Taste and adjust with extra salt or cayenne if you want more kick. Serve immediately for best crunch with ranch, ketchup, or spicy mayo.

Quick tips I use all the time: don’t overcrowd the pot, keep the oil temp steady with a thermometer, use peanut oil for better flavor and higher smoke point, double frying is the secret to crispiness, and if you want to make ahead you can par fry, refrigerate on a tray, then re-fry at 375 F right before serving.

FAQ

Q: Can I use a different potato than russet? A: You can, but russets are best because they have high starch and low moisture so they crisp up good. Yukon golds will work but they get a bit softer and not as crunchy.

Q: Why is there flour and cornstarch in the seasoning? A: The flour and cornstarch create a light coating that helps the spices stick and gives that slightly crispy exterior you expect from Popeyes style fries. Cornstarch is the real trick for extra crunch.

Q: My fries went soggy, what did I do wrong? A: Usually it's from not drying the potatoes well, overcrowding the fryer, or frying at too low a temp. Make sure fries are dry, fry in batches, and keep oil around 350 to 375°F. Also let them rest on a rack not paper towels so steam doesn't make them soggy.

Q: Can I bake them instead of frying? A: Yes, if you want a healthier option. Toss in a little oil, bake on a hot sheet at 425 to 450°F, flip once, and spray with a bit more oil for extra crisp. They won't be identical to deep fried but still tasty.

Q: Is MSG necessary? A: No, it's optional. MSG gives that umami boost and makes the seasoning taste more like the restaurant version, but if you avoid it for dietary or personal reasons the fries will still be great.

Q: How do I reheat leftovers so they stay crispy? A: Reheat in a hot oven or air fryer at 400°F for 5 to 8 minutes. Avoid the microwave, it makes them limp. If they feel a bit dry, toss with a tiny bit of oil after reheating.

Popeyes Cajun Fries Recipe Substitutions and Variations

Vegetable/peanut oil: can swap with canola oil, sunflower oil, or avocado oil. They fry hot and neutral, so results are nearly the same. If using peanut and you have allergies, pick canola.
Cornstarch: replace with arrowroot powder or tapioca starch for the same crisp. If you dont have either, plain rice flour works okay but is a bit grittier.
MSG (optional): skip it or use a pinch of powdered chicken bouillon, mushroom powder, or a small splash of soy sauce in the cold water to get that savory boost without MSG.
Cayenne pepper: sub with hot smoked paprika, chipotle powder, or a mix of regular paprika plus a pinch of crushed red pepper flakes. Adjust amount for heat level you want.

Pro Tips

1. Dry the fries like your life depends on it. After rinsing and soaking, pat them completely bone dry or they wont crisp and the oil will spit. Use a clean kitchen towel or multiple paper towels and give them 5 extra minutes of air drying if you can.

2. Keep a thermometer handy and work in small batches. Fry at the lower temp first to cook through, then raise the heat for the finish. Don’t overcrowd the pot or the oil temp will crash and you end up greasy fries.

3. Toss the seasoning while the fries are very hot and do it in small handfuls. Make the seasoning paste just tacky, not soupy, so it clings and forms a thin crunchy shell. If you add too much water, a quick sprinkle of extra dry seasoning helps.

4. For make-ahead or party service: par-fry and cool the fries on a wire rack in a single layer, then refrigerate on a tray. When ready, re-fry at the higher temp until golden to revive crispness. Reheating in a hot oven or an air fryer also works if you dont want to refry.
