- 1/2 teaspoon ground black pepper: Adds sharpness and enhances the spiciness.

How to Make Cajun Spiced Sweet Potato Fries Recipe
Step 1: Preheat Your Air Fryer
Start by warming up your air fryer to 400°F for about 3 minutes. This step is essential because a properly preheated air fryer cooks your fries evenly, helping achieve that coveted crispy exterior and tender inside.
Step 2: Prepare and Coat the Sweet Potatoes
Peel your sweet potatoes and slice them into uniform 1/4-inch fries. Toss the cut fries in a large mixing bowl with 1 1/2 tablespoons of olive oil until every piece is lightly but thoroughly coated. This oil layer not only promotes crispiness but also helps the spices stick better.
Step 3: Mix Your Spice Blend
In a small bowl, combine smoked paprika, garlic powder, onion powder, dried oregano, dried thyme, cayenne pepper, black pepper, and fine sea salt. Stir until the blend is even in color and texture—that’s when it’s ready to flavor your fries!
Step 4: Season the Fries
Sprinkle the Cajun spice blend evenly over the oiled sweet potatoes. Toss everything together so every fry wears a beautiful coat of seasoning. This step is where your fries turn from plain to punchy and full of Cajun personality.
Step 5: Arrange Fries in Air Fryer
Place the seasoned sweet potato fries in the air fryer basket in a single layer. Avoid crowding to ensure each fry crisps up perfectly. If needed, cook in batches—patience here pays off deliciously.
Step 6: Air Fry Until Golden and Crisp
Cook at 400°F for 15 to 20 minutes, shaking or turning the fries halfway through. This keeps the cooking uniform and achieves that crispy, golden finish that makes this Cajun Spiced Sweet Potato Fries Recipe so irresistible.
Step 7: Serve and Enjoy
Once done, transfer your fries to a serving plate and garnish with fresh parsley if you like. Serve immediately for best crunch and flavor—these fries are best enjoyed hot!

Garnishes
Fresh parsley offers a vibrant green pop that contrasts beautifully with the reddish-orange fries. You can also sprinkle a little extra sea salt or a squeeze of fresh lemon juice to enhance the savory and tangy notes of the dish.
Side Dishes
These Cajun spiced sweet potato fries pair wonderfully with plant-based burgers, grilled veggies, or a tangy dipping sauce like vegan ranch or spicy aioli. They’re versatile enough to elevate any casual meal or party spread.
Creative Ways to Present
For a fun twist, serve these fries in individual small baskets lined with parchment paper, or layer them in a rustic wooden bowl topped with colorful herbs and edible flowers. It’s a feast for the eyes as well as the palate.
Make Ahead and Storage
Storing Leftovers
Store leftover fries in an airtight container in the refrigerator for up to 3 days. To keep them at their best, spread them out to avoid sogginess caused by trapped moisture.
Freezing
You can freeze cooked sweet potato fries, though they are best fresh. To freeze, bake the fries on a tray until just cooked but not browned, then freeze spread out before transferring to a sealed bag. Reheat directly from frozen for best results.
Reheating
Reheat leftover fries in an air fryer or oven at 375°F for 5 to 7 minutes to restore their crispiness. Avoid microwaving, as it tends to make the fries soggy and less enjoyable.
FAQs
Can I use regular potatoes instead of sweet potatoes?
Absolutely! While this recipe shines with the natural sweetness of sweet potatoes, you can substitute with regular russet potatoes. Just keep in mind that the texture and flavor profiles will differ, with russets being less sweet but equally delicious.
Is it possible to make these fries without an air fryer?
Yes, you can bake the fries in a conventional oven at 425°F for 25-30 minutes, flipping halfway through, to achieve a similar crispy texture, though the air fryer usually yields the best crunch.
How spicy are these fries?
The spice level is moderate with a bit of heat from cayenne pepper, but you can adjust the amount up or down depending on your preference for mild or bold spice.
Can I make this recipe gluten-free and vegan?
Definitely. This Cajun Spiced Sweet Potato Fries Recipe is naturally plant-based and gluten-free, making it suitable for a wide range of dietary needs without any modifications.
What dips go well with Cajun Spiced Sweet Potato Fries?
Dips like vegan garlic aioli, spicy ketchup, or a cooling avocado crema complement the fries perfectly by balancing their smoky, spicy flavor with creamy or tangy notes.
