What you will need
- Sweet potatoes - Make sure to follow the tips below for soaking and drying the potatoes
- Oil - We used a good quality olive oil, but vegetable oil or sunflower oil will work too.
- Cornstarch - Also known as corn flour. This is the secret ingredient to getting crispy fries.
- Seasoning - We went with garlic, parsley, sea salt and black pepper
Step by Step
One: Cut the sweet potatoes into fries about 1.5cm thick.
Two: Soak the fries in a bowl of water for 10 minutes. Dry with a towel.
Three: Place the soaked and dried potatoes in a large bowl and add the oil, cornstarch, garlic and parsley and mix well.
Four: Place them on to a baking tray and spread out so there is enough space between the fries. Put them in a preheated oven at 200°C/400°F/Gas 6 for 15 minutes. Flip the fries and then cook for a further 20 minutes, or until crispy.
Why should you try it?
- Great alternative to potato fries
- Vegan
- Easy to adapt with different seasoning
- Crispy, without being fried
Health benefits of sweet potato
Whilst there is nothing wrong with white potatoes, we love them, sweet potatoes make a nice change to regular fries and they have lots of nutritional benefits. Not only a good source of fibre, but packed with B vitamins and vitamin C too. They are also high in beta-carotene.
Baked, not fried
Whenever I post about sweet potato fries, someone tells me that they have tried to bake them but they never work and they always end up falling apart, so I thought I would share my method for making them.
You are never going to get them crispy like they are when deep fried, unless you burn them in the oven, but you can still make them crispy and super delicious in the oven by following our steps.
Seasoning
We could eat fries every day of the week, but having them the same way would get boring. An easy way to change them up each time is to use a different seasoning.
This recipe uses garlic granules, dried parsley and some salt and pepper. But you really could use anything you like. A Cajun or Mexican blend seasoning would work well, or just some chilli powder.
FAQs
You can use this exact recipe to make air fryer sweet potato fries too and they will get just as crisp. You can even use a little less oil if you like, as that's one of the great things about an air fryer.
Nobody wants a soggy floppy sweet potato fry - it's all about the crispiness. When you get them in a restaurant, they are always perfectly crispy, but usually fried. We wanted to keep them baked, but still with some crispiness.
The key to getting them crispy in the oven is rinsing them in cold water to get off any extra starch and then making sure they are dried of any water, so they crisp rather than steam. Cornstarch is also essential to a crispy baked fry, and you can mix it with the other seasonings before coating.
It's also important to make sure that you don't put too many fries in one pan and overcrowd them. They like their space, so use two pans if needed. Also, cook them at a high temperature. Following these simple steps will help you get that crispy baked fry that you want.
Extra tips
- To get crispy fries, soak them in water first and make sure they are dried well.
- Mix cornstarch with your seasoning for extra crispy fries.
- It's important to make sure you don't put too many fries in one pan, so space them out.
- Get creative with the seasoning. A Cajun or Mexican blend seasoning would work well.

Will these work in an airfryer?
Dannii
Yes, they will work in an air fryer and you might not need to use as much oil either.
Kay
You mention garlic, but it is not listed in the ingredients. How much garlic?
Dannii
At the top of the post it says 1tbsp garlic granules. I will add it to the recipe card too. I hope you enjoy.
Gloria @ Homemade & Yummy
These fries look amazing, love the fact they are not deep fried. Great use of sweet potato.
Dannii
Thanks! I much prefer them baked, especially when you can still get them crispy.
Dannii
I think that is why they don't turn out right for most people.

Sweet potato fries are some of my favorite things, and I choose them over regular fries all the time! These look just perfect. :)
Dannii
They have to be crispy though :)
Kelly
These look perfect, Dannii! I feel the same way, I can never resist a plate if they are on the menu! Baking them at home is so much healthier though! Yay, congrats on the Weight Watchers collaboration too :)

Petra / Be Healthy Now
My boyfriend loves sweet potato fries, will have to try your healthier version and see how that turns out! Normally when I bake slices of sweet potato in the oven, they always turn out soft.
Dannii
They key is to not cook too many at one time, as they won't get crispy.
Idaintyit
I love sweet potato fries but they always go soft and break when I take them out, now I know why! Thanks for the tip

Well done on your amazing weight loss! That's fantastic!
The sweet potato fries look awesome. I'm such a sucker for them - I'll always order them at a restaurant (or swap normal fries for them). Restaurant ones are probably not that much healthier than regular but they taste 100 times better. Love this healthy version though.
Dannii
I notice the sweet potatoes in all your rib photos ;)
