Sometimes, the best part of dinner isn’t the main course — it’s the side dish that steals the show. And in today’s case? That title goes to Cajun Spiced Sweet Potato Fries. These fries are crispy on the outside, tender on the inside, and packed with just the right amount of smoky heat. Whether you’re dunking them into your favorite sauce or devouring them straight from the tray, they’re impossible to resist.
🍠 Why Sweet Potato Fries?
Let’s be honest — sweet potatoes bring something special to the table. They’ve got natural sweetness, beautiful color, and just enough starch to get that golden, crisp edge. When you spice them up Cajun-style? Game over.
These aren’t your soggy, bland fries. We’re talking about the kind you crave after trying them once.
🔥 What Makes Them Cajun?
Cajun seasoning is a spicy, smoky, earthy blend that originated in Louisiana cuisine. It typically includes:
- Paprika (often smoked)
- Garlic powder
- Onion powder
- Oregano
- Thyme
- Black pepper
- Cayenne
It’s bold and exciting — but not overwhelming. You can make your own at home or use a store-bought version if you’re in a rush. Either way, it brings heat and personality to these fries.
🛒 Ingredients You’ll Need
No long shopping list here — just pantry staples and a few good sweet potatoes.
For the Fries:
- 2 large sweet potatoes (orange-fleshed works best)
- 2 tablespoons olive oil or avocado oil
- 1½ teaspoons Cajun seasoning
- ½ teaspoon garlic powder
- ½ teaspoon smoked paprika (optional for extra smokiness)
- ½ teaspoon salt
- Freshly ground black pepper to taste
- 1 tablespoon cornstarch (optional, for added crispness)
For Dipping (Optional Ideas):
- Garlic aioli
- Chipotle mayo
- Classic ketchup
- Greek yogurt ranch
- Avocado crema
🔪 How to Cut Sweet Potato Fries (Without Tears)
Cutting sweet potatoes can be a workout — they’re dense! But here’s how to make it easier:
- Peel the sweet potatoes (optional).
- Slice off the ends for stability.
- Cut in half lengthwise.
- Slice into ¼-inch thick planks.
- Stack the planks and cut into fries.
Aim for uniform thickness so they cook evenly. You’re going for thin sticks, not wedges.
🧂 Pro Tip: Toss with Cornstarch First
If you want that irresistible crisp edge, toss your fries with a bit of cornstarch before adding oil and seasoning. It helps draw out moisture and creates that signature fry texture — especially when baking.
🔥 Baked vs. Air Fried vs. Deep Fried
| Method | Pros | Notes |
|---|---|---|
| Baked | Healthier, hands-off | Use parchment & space fries |
| Air Fried | Crispy & fast, low oil use | Shake halfway through |
| Fried | Crispiest result | More mess & oil required |
We’ll focus on the baked method today — it’s the sweet spot between flavor, texture, and ease.
🍳 Step-by-Step: Baked Cajun Sweet Potato Fries
Step 1: Prep the Fries
Preheat your oven to 425°F (220°C). Line two baking sheets with parchment paper.
Wash and dry your cut fries thoroughly — moisture is the enemy of crispiness.
Step 2: Coat and Season
In a large bowl, toss the fries with cornstarch (if using) until lightly coated. Then drizzle with oil and sprinkle in Cajun seasoning, garlic powder, smoked paprika, salt, and pepper. Toss again to coat evenly.
Step 3: Spread Out
Spread the fries in a single layer on the baking sheets. Give them space — overcrowding = steaming.
Step 4: Bake
Bake for 15 minutes, then flip the fries and rotate the trays. Bake another 10–15 minutes, or until golden and crispy at the edges.
Step 5: Cool Slightly
Let the fries sit for 5 minutes before serving. This helps them firm up a bit more.

💬 From My Kitchen: A Crispy Discovery
I used to avoid making sweet potato fries at home — they always turned out limp or burnt. But after trying the cornstarch trick and spacing them like introverts at a party? Magic. Now I make them almost weekly. Sometimes I toss in a little rosemary or even cinnamon sugar for a twist.
One time I made them for friends during game night — no one touched the chips. That’s how good they were.
🧪 Experiment & Customize
Not a fan of heat? No problem.
| Want This… | Try This… |

| Less spicy | Omit cayenne or reduce paprika |
| More savory | Add Parmesan after baking |
| Vegan dip | Use tahini-lemon sauce |
| Sweeter version | Toss with cinnamon and sea salt |
Sweet potatoes are flexible — make them your own!
