Sweet potatoes cook differently from normal potatoes – meaning that making sweet potato fries in the Actifry can be a little tricker.
Sweet potatoes contain less starch than normal potatoes, and release more steam when cooking. Because of this, we need to make sure to add a little extra starch (in the form of cornflour) and not to crowd the pan.
Whenever i try to cook them with the paddle in, they end up bunched up and crushed by the end of the cooking time.
Below is the method I use to cook really tasty, crispy sweet potato fries in my Actifry.
Unfortunately, I haven’t found a method to cook a large batch of sweet potato fries without making them soggy (I tend to bake them if i’m cooking for a crowd). The below recipe is suitable for a smaller batch (which would serve 2 people perfectly). I do have the original Actifry though, which is the smallest model – if you have a family sized Actifry you’ll fit more in on a single layer!
How to make sweet potato fries in an Actifry Air Fryer:

1. Peel your sweet potatoes and chop off the pointy ends
2. Then chop into equal sized fries
3. Place the sweet potato fries into cold water and rinse until the water runs clear – this step is important.
4. Dry the sweet potato fries on a clean tea towel until they’re completely dry.
5. Add the dry chips to a large sandwich bag
6. Then add 1 tbsp of cornflour
7. And shake the bag until the fries are evenly coated
8. Once the fries are coated in the cornflour, add the oil to the bag and shake so the fries are evenly coated.
9. Place the oiled sweet potato fries into the Actifry, being sure not to bunch them all up. You need an even single layer. Turn on the Actifry (without the paddle) and cook for 15 minutes.
10. After 15 minutes, use a wooden or silicone spatula to turn the fries. My Actifry has a hot spot near the back which cooks quicker, so I always rotate the fries to ensure none burn. Cook for a further 10 minutes.
11. After the full 25 minutes the sweet potato fries should be cooked and crispy! You’ll notice from the image below how much the fries shrink from being raw – keep this in mind when chopping!
12. Once cooked, drain any access oil on a paper towel.

HI, I see you mention cornfour, which is yellowish, but on the pics its white, like cornstarch. Which one do you actually use? I dont live in the USA so i have to translate this into German, Thanks.
By the way, it looks yummy, I tried it myself once, not according to this recipe, and they were really mushy.
Hi Jelena 🙂 I’m in the UK – and UK corn flour is the same as U.S. cornstarch, so, it’s the white stuff (US cornstarch) – how confusing 🙂
Thank you becsuse in Canada we also call it cornstarch!
Hi Helen. When you take out the agitator do you put baking foil in its place? If so, why?
Many thanks – Angela
Hello, I used to do this when I had the ‘original’ model, as when the paddle was removed it was just a hole / things would fall in under the pan. Now I have a genius I no longer need to do this (as it’s not just an open hole). I don’t know/think it’s essential, just something I used to do to save cleaning inside / was worried bits would get into the motor
My 3 small potatoes, cut in french fry cutter with ends cut into medallions gave me a much bigger yield than what you pictured. I used the stir paddle following your method except for adding the oil in the fryer rather than in the bag. Took 35 minutes and came out perfect, no broken pieces.
Good day, have made these several times now and have no problem with using the paddle. No breakage.
Hello. I have the old original Actifry. I’m guessing most of your recipes can’t be made in that? Only the dry ones as garlic fries, garlic broccoli, brussel sprouts and this one? I’ve never really used it much. Just for frozen fries and a few times for frozen spring rolls. But was thinking maybe I should try a few more things before replacing it with an airfryer. It just doesn’t seem like much can made in it compared to an airfryer?
Hello, they all can 🙂 majority of my recipes are actually in the original Actifry – I have also recently repurchased a slightly smaller model of the Actifry which would be suitable (so all my future recipes).
I’d definitely try a few more things – one you get the hang of it it is great 🙂
Okay. Thanks. I was worried sauce/liquid would get under the bowl. And it seems too small for for instance the chili con carne recipe. I tried a cauliflower recipe which said to give it 15 minutes but I had to almost double the time (28 minutes). How much noise does the Ninja make compared to the original Actifry?
