Curried sweet potato oven fries are a great side dish or late night snack. The fries are deeply seasoned and absolutely delicious dipped in rich, creamy cumin ketchup.
These oven fries are a snap to make. Just slice your sweet potatoes and toss them with the oil and spices. While they bake, you can whisk together the ketchup ingredients, so your dipping sauce will be ready as soon as the fries come out of the oven.
If you want to skip on prep, you can use frozen sweet potato fries and either make them in the oven using my spice mix or make them in your air fryer. If you're making air fryer frozen sweet potato fries, add the spices in the last few minutes of cooking, so they don't burn.

🔪 How to Make Sweet Potato Fries in the Oven
Preheat the oven to 400° F. If you're air frying, prep the sweet potatoes the same way, and see the air fryer cooking directions in the recipe card notes section.
Cut your sweet potatoes into about ¼" sticks. They should be about as wide around as your pinky, but longer is fine. Arrange the sweet potato slices on a cookie sheet, and drizzle the olive oil over them.
Sprinkle on the curry powder, coriander, and sea salt. Toss them well to coat them in the oil, spices, and salt, adding more the oil, if necessary, to get all the spices stuck to the sweet potato pieces.
Arrange the fries in a single layer on a lined baking sheet. Bake for 45-60 minutes, stirring every 15 minutes, so the fries cook evenly. If they look like they're drying out, spray with some extra oil to help them brown without burning.
When they look brown and a little crispy, they're done. You can cook longer for crispier fries, if you like, just check in often to avoid burning.
Meanwhile, make the cumin ketchup by whisking all of the ingredients together in a small bowl.
Serve the sweet potato oven fries with the creamy cumin ketchup on the side.
💡 Helpful Tips
- Consistency of size is key with sweet potato fries, so try to make sure your pieces are pretty uniform in width. It's okay if they're longer or shorter, but you'll get the best results if they're all roughly ¼" thick.
- Don't wait until the fries are done to make the dipping sauce. You have time to make the dip and clean up the kitchen while the fries bake or fry up in the air fryer! The listed cooking time is for the oven. In the air fryer, the cooking time drops to 20 minutes, so it only takes 30 minutes total. The shorter cooking time is stil plenty of time to make the ketchup and clean before you dive into your basket of fries!
- You can double or triple this recipe, but I would do that in multiple batches, if you're planning to air fry.
🫙 Storage Directions
Leftover sweet potato oven fries will keep for 3 to 4 days in the refrigerator. Reheat in the oven or air fryer at 350° F until warm and crisp. The cumin ketchup will keep for up to a week.
💬 Frequently Asked Questions
Sweet potato fries, especially baked ones, don't get as crispy as fries made from white potatoes. That's because sweet potatoes are less starchy than white potatoes. You can toss in some cornstarch before baking, if you like, to get them crispier.

These look delicious! We make sweet potato fries with dinner often. It's so easy to keep a few sweet potatoes around, and they liven up a meal. What's interesting, though, is that I cook them for about half of that cooking time. I usually do just 30 minutes. I wonder if I cut mine thinner, or if they'd get crispier if I did them your way. I'll have to give it a shot!

Very interesting! Let me know how it compares for sure.
