The Perfect Sweet Potato Fries

Please welcome my guest poster Sarah, a 33-year-old Don’t-Stay-at-Home Mom of 3 beautiful girls, who blogs at Real Life, teaches piano lessons and has found ‘real life’ in Jesus Christ.

My favorite local restaurant serves the most incredible sweet potato fries! Since my husband and I have a hobby of trying to recreate our favorite restaurant meals, we did just that with the sweet potato fries. We sliced them up and threw them in the fryer, and the resulting culinary disaster ended with soggy orange stringy-things in the trash can of our kitchen.
Well, lucky for me I know the owner and head chef! So I commenced to pick his brain regarding the perfect way to make sweet potato fries. Lucky for you, I am going to share it here!


  • • Desired amount of Sweet Potatoes
  • • Vegetable Oil in a Deep Fryer
  • • Salt to taste


  • Step 1: Fill your Deep Fryer with oil, according to the manufacturer’s directions. Preheat the oil to 325 degrees.
  • Step 2: Peel your sweet potatoes and cut them in quarter inch strips. Rinse the sweet potato strips thoroughly. This washes off the starch, which can make the fries gummy and soggy.
  • Step 3: Spread the strips out on paper towels, and let them dry for at about 30 minutes. It’s important for the potatoes to be dry before they hit the oil.
  • Step 4: Carefully lower the strips into the fryer, and cook for 5 minutes on 325. Remove the fries and set out on paper towels. This is the pre-cooking stage. For some reason, unbeknownst to me, this helps make them crispy later. At this point, you can freeze them for later use, or put them in the refrigerator if you plan to use them the next day.
  • Step 5: Heat the oil up to 350. When you are almost ready to eat, put the precooked sweet potatoes into the hotter oil for 5-6 minutes, or until desired crispiness. Make sure you watch them to avoid overcooking.
  • Step 6: Dust with desired amount of salt, and serve hot! But make sure you set some aside before giving them to your guests. These babies fly off the plate!

There are a variety of ways to “kick it up a notch” when making these sweet potatoes. Mix some cayenne pepper and a pinch of cinnamon with the salt, before you sprinkle it on. Serve with Chipotle Ranch dip, or Bleu Cheese dressing. As for me, the crisp, salty sweet potato goodness stands on its own! I suppose you could save some calories by baking these fries, after spraying them with cooking spray, but…why?

    I bake them instead of frying. I’ve used a variety of different flavorings on them. The other night we made them along with regular potato fries in the oven also because I had one sweet potato extra laying around. I just cut them up in about 1/4″ strips and then did the same I was doing to the potatoes. This night that happened to be tossing them in some Italian dressing and some Parmesan cheese (the Kraft canned type for this). Then I just put them on the sheet pan and cook them at 375 for about 45 minutes or so. These are not crisp fries at all – but have a very nice flavor still.

    These sound delicious. I order sweet potato fries at one of our favorite local restaurants in the suburbs of Philly on every visit there. (Iron Hill Brewery) I’d love to try this – but I guess I would need a Deep Fryer. Wonder how it would go with baking? Broiling? Probably not well – If you tried anything else, let me know. Thanks!

      You can totally make this without a fryer! Just par-boil the fries first for 4-5 minutes, then sieve and dry. Lightly grease a baking pan with oil and make sure the fries are coated. Put them in the oven and either bake at a high temp or broil. Turn every now and then to make sure all sides brown evenly.
      This works with halved New Potatoes or even Floury potatoes as well.. They are gorgeous and crispy on the outside and soft and melty inside.

    I have friend them and coated them with a salt and sugar mix. The little bit of sweetness from the sugar does something– yum- yum

    I love sweet potato fries, too! We don’t have a fryer (I’d probably use it too much) so I bake them in the oven. Mmmm!

    I’ve never made sweet potato fries, but they’re one of my must-haves at the MN State Fair. You can order “savory” with ranch dressing, or “sweet” with cinnamon (as you mentioned) and real whipped cream as a dip. I always get the sweet- soooo yummy!

    I’m so glad you posted this because we have had a similar experience. A favorite restaurant of ours serves these fries and that’s really all we want to eat! I also love recreating great restaurant meals at home so I bought some sweet potatoes to fry at home but I was pretty sure it wouldn’t be good to just peel, cut and fry. Thanks to your tips I’ll be adding these to our menu this week for sure!

    I love sweet potato fries. I often bake them. However first I cook them in the microwave for 3 minutes, then I put them in the oven. This helps them get crispy instead of being soggy. I sprinkle them with chopped up rosemary, sea salt and Parmesan cheese. Then we dip them in spicy ketchup (just ketchup mixed with spicy chili sauce).

    They look yummy! Easy and yummy!

    I had some wonderful sweet potato fries about a month ago and have thought about them since then. They were light and crispy like regular fries and dusted with cinnamon sugar. I knew there was a trick to getting them so crispy but couldn’t figure it out. Thank you for posting this. I am about to go to the kitchen and give this a try. They should go very nicely with our ciabatta steak sandwiches. I’m very excited!

    I tried to make sweet potato fries and they came out limp and not crispy. I know what to do now to get a crispy fry. Thanks. I love to eat them with cinnamon and sugar sprinkled on them and I like to dip them in Apple Butter. Mmmmmm. Good.
