Pin it My roommate came home one afternoon with a bag of sweet potatoes and a challenge: make something that would beat the frozen fries I'd been relying on. I had some smoked paprika and cayenne sitting in my spice rack, and honestly, I just started tossing things together. Twenty minutes in the air fryer later, golden-brown fries emerged that tasted like someone had actually cared about making them. That was the day I stopped apologizing for my snack choices.
I brought a batch to a game night, assuming they'd be gone in minutes as an afterthought. Instead, people kept asking if I'd made them from scratch and whether I could share the recipe. Standing there watching someone close their eyes while eating a sweet potato fry is weirdly satisfying, like you've accidentally created something that matters.
Ingredients
- Sweet Potatoes: Two large ones, cut into 1/4-inch fries—thin enough to crisp up fast, thick enough to stay creamy inside. Peeling is non-negotiable here.
- Olive Oil: The 1 1/2 tablespoons is the glue that holds everything together and helps the spices stick without drowning them.
- Smoked Paprika: One teaspoon brings warmth and color; skip the regular paprika unless you want something flatter.
- Garlic Powder: One teaspoon rounds out the spice profile with a savory note that feels more complex than it has any right to.
- Onion Powder: Another teaspoon deepens the flavor without any wet onion pieces to worry about.
- Dried Oregano and Thyme: Half a teaspoon each add an herbal backbone that whispers instead of shouts.
- Cayenne Pepper: Half a teaspoon is the gentle heat; start here and work up if you like things spicier.
- Black Pepper and Sea Salt: The finishing touches that wake everything up.
- Fresh Parsley: Optional but worth it for the green pop and fresh note against all that warmth.
Instructions
- Heat your air fryer:
- Set it to 200°C (400°F) and let it preheat for a full 3 minutes. This matters more than you'd think.
- Coat the fries in oil:
- Toss the cut sweet potatoes in a large bowl with olive oil, making sure every piece gets a light coating. Don't be shy, but don't drown them either.
- Make the spice blend:
- Mix paprika, garlic powder, onion powder, oregano, thyme, cayenne, black pepper, and salt in a small bowl. Combine everything so you're not sprinkling random individual spices and wondering why some bites taste different.
- Season generously:
- Sprinkle the spice mixture over the oiled fries and toss until they're evenly coated. This is the moment that determines whether you'll love them or wonder what happened.
- Arrange and fry:
- Spread the fries in a single layer in your air fryer basket. If they overlap too much, do two batches; crowding them guarantees they'll steam instead of crisp.
- Cook and shake:
- Air-fry for 15–20 minutes, stopping halfway through to shake the basket or flip them with tongs. You're looking for golden brown and crispy, not burnt at the edges.
- Finish strong:
- Transfer to a plate, hit them with fresh parsley if you have it, and eat them while they're still warm and at their crispiest.
Pin it There was this moment during meal prep when I realized these fries weren't just a side anymore. They'd become the thing people asked for, the thing I made when I wanted to feel like I was taking care of someone, even if it was just myself on a Tuesday night. Food does that sometimes.
The Dipping Sauce Question
Garlic aioli is the obvious move, but they're equally happy with sriracha mayo, a sharp ketchup, or even just sitting plain on the plate. I've found that the best sauce is usually whatever's already in your fridge that you won't feel bad about opening for something this good. Don't overthink the sides.
If You Don't Have an Air Fryer
Bake them at 220°C (425°F) for 25–30 minutes on a parchment-lined baking sheet, flipping halfway through. They won't be quite as crispy, but they'll still taste good enough that you'll understand why this recipe exists. The air fryer just cuts the time and guarantees the texture.
Making Them Your Own
These spices work as written, but this is a template, not a law. I've played with smoked salt, added a tiny bit of cinnamon, experimented with different heat levels. The foundation—sweet potatoes, oil, bold spicing—is what makes them special.
- Reduce the cayenne to a quarter teaspoon if you're cooking for people who prefer mild food.
- Toast whole spices in a dry pan before grinding if you want to deepen the flavor even more.
- Toss in a squeeze of lime juice or lemon zest right after they come out of the fryer for brightness.
Pin it These fries have a way of turning a quiet evening into something worth remembering. Make them, share them, and watch what happens.
