Ingredients
- Sweet potatoes: Choose firm, evenly shaped ones for consistent cooking and natural sweetness that balances the spice
- Olive oil: Helps achieve that perfect crispy exterior while adding heart-healthy fats
- Cajun seasoning: The star ingredient providing complex heat and flavor in one convenient blend
- Garlic powder: Adds depth and savory notes that complement the sweet potatoes
- Salt: Enhances all the flavors and draws out moisture for extra crispiness
Step-by-Step Instructions
- Prep the Sweet Potatoes:
- Wash sweet potatoes thoroughly under cool running water, scrubbing gently to remove dirt. Pat completely dry with paper towels. Using a sharp chef's knife, slice each potato in half lengthwise, then cut each half into 3-4 wedges of equal thickness. Uniform size ensures even cooking.
- Season to Perfection:
- Place cut wedges in a large mixing bowl with plenty of room. Drizzle olive oil evenly over wedges and toss gently with your hands, ensuring each piece gets a light coating. Sprinkle Cajun seasoning, garlic powder, and salt over the oiled wedges. Mix thoroughly until each wedge is evenly coated with spices.
- Air Fry to Crispy Goodness:
- Preheat your air fryer to 400°F for at least 3 minutes. Arrange sweet potato wedges in a single layer in your air fryer basket, being careful not to overcrowd. Cook for 6 minutes, then carefully shake the basket or flip each wedge individually with tongs. Continue cooking for another 6-9 minutes until edges are deeply golden and crispy.
- Serve Immediately:
- Transfer hot wedges to a serving plate and enjoy while still piping hot for maximum crispiness. The contrast between the crispy exterior and tender interior is best experienced fresh from the air fryer.

The Cajun seasoning is truly the heart of this recipe. I keep a homemade batch in my pantry at all times after learning the technique from my neighbor who grew up in Louisiana. The blend of paprika, cayenne, herbs and garlic creates a complexity that elevates these simple wedges into something truly craveable.
Choosing the Right Sweet Potato
Not all sweet potatoes are created equal for this recipe. Look for the reddish-orange skinned varieties often labeled as "garnet" or "jewel" sweet potatoes. These have a moister, more tender flesh compared to the drier, starchier white-fleshed varieties sometimes called yams. The natural sweetness of orange sweet potatoes creates the perfect canvas for spicy Cajun seasoning, creating that irresistible sweet-heat combination.
Troubleshooting Crispiness
If your sweet potato wedges aren't getting crispy enough, there are a few common culprits. First, moisture is the enemy of crispiness. Make sure to thoroughly pat dry your potatoes before cutting and oiling. Second, overcrowding the air fryer basket prevents proper air circulation. Work in batches if needed, keeping finished wedges warm in a low oven. Finally, cutting wedges too thick can result in soggy centers before the outsides crisp up. Aim for wedges about 1/2-inch thick at their widest point.
Dipping Sauce Pairings
While these Cajun sweet potato wedges are delicious on their own, pairing them with the right dipping sauce elevates them to new heights. My favorite is a quick sriracha-lime mayo made by mixing 1/4 cup mayonnaise with 1 teaspoon sriracha and a squeeze of fresh lime juice. For a cooling contrast, try a simple Greek yogurt sauce with chopped fresh herbs. The tangy creaminess balances the spicy wedges perfectly and turns this simple side into a satisfying snack.

These wedges will transform your mealtime – crispy, spicy and effortless perfection every time!
Frequently Asked Questions
- → Do I need to peel the sweet potatoes before cooking?
No, you don't need to peel the sweet potatoes. Simply wash them thoroughly, pat dry, and cut into wedges. The skin adds texture and contains nutrients.
- → Can I make these without an air fryer?
Yes, you can bake these in a conventional oven at 425°F (220°C) for 25-30 minutes, turning halfway through. They won't be quite as crispy but will still taste delicious.
- → What can I serve with these Cajun sweet potato wedges?
These wedges pair wonderfully with dipping sauces like sriracha mayo, ranch dressing, or garlic aioli. They also make an excellent side dish for burgers, grilled chicken, or sandwiches.
- → Can I adjust the spice level?
Absolutely! Reduce the amount of Cajun seasoning for a milder flavor or add a pinch of cayenne pepper if you prefer more heat. You can also substitute other seasoning blends like taco seasoning or Italian herbs.
- → How do I store leftover sweet potato wedges?
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the air fryer at 350°F (175°C) for 3-4 minutes to restore crispness.
- → How thick should I cut the sweet potato wedges?
Aim for wedges about 1/2 inch thick at their widest point. Cutting them uniformly helps ensure even cooking. Wedges that are too thin may burn, while thicker ones might not cook through completely.
