Perfect Sweet Potato Oven Fries

sweet potato fries

There’s no denying the pull of French fries, but it’s rare that we have the time — or the desire! — to do any real deep-frying at home. That’s why you need a technique for making fries in the oven that gives you great results every time: a crispy, flavorful fry with a soft and tender interior. Add even more color and vitamins to the plate by making them sweet potato fries. With these sweet potato oven fries in your repertoire, you’ll have a great side dish for any occasion.


As with any good French fry recipe, you will need to blanch the potatoes first. Blanching potatoes ensures that they will have a soft interior.

Slice the sweet potatoes into even fries and place into a pot of cold, salted water. Bring to a boil and cook for 10 minutes, until just slightly tender. Drain and dry completely on a clean dish towel.


Roasting the potatoes is what will give them the crispy exterior you’re craving.

Preheat the oven to 400 degrees F. Toss the blanched potatoes in just enough olive oil to coat, and salt them generously. At this point, you can also add any flavors you like, such as cayenne pepper for a spiced fry. If you’d like to add fresh or dried herbs, wait until 5 minutes before the end of cooking. Place in one layer on a baking tray and roast for 20 minutes, flipping at least once.

Serve your fries with your condiment of choice: harissa, homemade ketchup, homemade mayonnaise, or homemade aioli, homemade mustard, or some of our other favorite French fry flavor boosters.
