Steps

Before you start

Preheat your air fryer to 400°F (200°C)
Pat potatoes dry thoroughly after soaking—moisture prevents crisping
Have all spices measured and mixed before you start

1
Prepare the potatoes
- Cut potatoes into ¼-inch-thick sticks about 3 inches long.
- Place in a large bowl and cover with cold water.
- Let soak for 5–10 minutes to release excess starch.

Ready when: Potatoes are cut to consistent thickness; water may look slightly cloudy
Tip: Keep the pieces uniform so they cook at the same rate
2
Drain and dry thoroughly
- Drain potatoes in a colander, then transfer to paper towels.
- Pat very dry—any moisture left on the surface will steam instead of crisping.
- Spread them on fresh paper towels and press gently to remove more moisture.

Ready when: Potatoes feel completely dry to the touch
Tip: This is the most critical step for crispy fries—moisture is the enemy
3
Mix the Cajun spice blend
- In a small bowl, combine paprika, garlic powder, onion powder, cayenne, thyme, oregano, black pepper, and salt.
- Stir to combine evenly.
- This spice blend keeps for up to 2 months, so you can make extra.

Ready when: Spices are evenly mixed with no visible clumps
Tip: Pre-mixing prevents uneven seasoning during the quick toss
4
Toss with oil and spices
- Place dried potatoes in the large bowl.
- Drizzle with olive oil and add the Cajun spice mix.
- Toss vigorously for 1–2 minutes until every piece is evenly coated with oil and spices.
- The potatoes should look glistening and spiced throughout.

Ready when: All potato pieces are visibly coated; no bare white spots remain
Tip: Don't skip thorough tossing—uncoated fries will taste bland
5
Arrange in the air fryerOven 400°F / 205°C
- Preheat air fryer to 400°F (200°C).
- Spread seasoned potatoes in a single layer in the air fryer basket, being careful not to overcrowd.
- They should lie flat with minimal overlap so hot air circulates around each fry.
- Work in batches if needed; overcrowding traps steam and prevents crisping.
+ Show details− Hide details
Ready when: Potatoes are arranged in one layer with space between pieces
Tip: Single layer is essential—stacked fries will steam rather than fry
6
Fry and shake halfwayOven 400°F / 205°C
- Cook at 400°F (200°C) for 10 minutes.
- Pause and shake the basket vigorously for 10–15 seconds to flip the fries and redistribute them.
- This ensures even browning on all sides.

Ready when: Fries are starting to turn golden at the edges
Tip: Set a phone timer so you don't forget the halfway shake
7
Finish cookingOven 400°F / 205°C
- Return to air fryer and cook for another 8–10 minutes at 400°F (200°C) until fries are deep golden brown and crispy on the outside.
- They will continue to crisp slightly as they cool.
+ Show details− Hide details
Ready when: Fries are golden brown throughout; when bent slightly, they resist and don't feel limp
Tip: A couple of slightly darker fries at the edges are fine—they add flavor, not burnt taste
8
Rest and serve
- Carefully pour fries onto a clean plate lined with paper towels.
- Let rest for 2–3 minutes to cool slightly and firm up further.
- Taste and add extra salt or spice if desired.
- Serve hot.

Ready when: Fries are cool enough to handle; paper towel has absorbed surface moisture
Tip: Add any extra seasoning while they're still warm so it sticks

Tips

The key to crispy fries is removing moisture—soaking and patting dry are essential steps; don't skip them
If your air fryer is smaller, cook in two batches rather than crowding; overcrowded fries will steam and turn limp
Shaking the basket halfway through is crucial for even browning; set a timer so you remember
Taste one fry before serving; Cajun spice varies by brand, so adjust the salt and cayenne to your preference

Make ahead

Fries are best eaten fresh, but you can prep the potatoes up to 4 hours ahead: cut, soak, drain, and dry them, then cover and refrigerate. Season and air-fry just before serving. The spice blend keeps in an airtight container for up to 2 months.

Storage & reheating

Store leftover fries in an airtight container at room temperature for up to 2 hours (they lose crispness quickly). Refrigerate for up to 2 days. Reheat in a 375°F (190°C) air fryer for 3–4 minutes to restore crispness. Do not freeze—the texture becomes soft and soggy.

Substitutions

paprika (sweet or smoked) → smoked paprika. Use the same amount for a deeper, smokier flavor without changing texture
cayenne pepper → hot paprika or red pepper flakes. Start with half the amount of red pepper flakes and taste; adjust heat to preference
olive oil or vegetable oil → vegetable oil, canola oil, or avocado oil. Any neutral oil works; avoid extra-virgin olive oil as it may burn at high heat
russet potatoes, medium → sweet potatoes or a mix of russet and sweet potatoes. Sweet potatoes may cook slightly faster (18–20 minutes total); watch closely for doneness
