The best crispy sweet potato fries recipe

I am obsessed with crispy sweet potato fries but was struggling to find a good recipe for them. As I have been working from home since last March due to the pandemic, I have had a lot more time to get creative and inventive in the kitchen. Frankly, sweet potatoes in any form are yummy, but I was struggling to get really decent crispy sweet potato fries at home! I tried recipe after recipe and was having no luck! I was determined to figure it out and after many kitchen disasters I finally nailed it!

I am excited to share my new favourite recipe with you, so enough waffle, here we go!

Ingredients list

  • Sweet potatoes (allow between 1 and 2 per person depending on the meal)
  • Corn flour (1/2 tablespoon per potato)
  • Olive oil (1/2 tablespoon per potato)
  • Salt
  • Pepper
  • Other seasonings (optional)

Steps

Turn on your oven and pre-heat to 225 degrees.

Give your sweet potatoes a wash, but you do NOT need to peel them.

Trim the ends, and then cut them up into fries, ideally no more than 1cm wide. It is tempting to make them wider because it means you get them chopped up quicker, but they will not be as nice or crispy, so take the extra time to cut them narrower.

Once you have cut them, put them in a large bowl, and add 1/2 tablespoon of corn flour per potato (so for 2 potatoes, just use 1 tablespoon).

Toss the contents of the bowl until the fries are covered with the corn flour.

Add the olive oil (again, 1/2 tablespoon per potato) to the bowl, and toss again.

Add salt, pepper and seasonings to flavour to your taste.

Lay the fries out on a baking tray, ideally spread out as much as possible. Use two trays if required. I use a chip tray with holes in it, and I think these give the best results. They don’t need to cost a fortune and you can get them in your grocery shopping at large supermarkets or online for just a few pounds.

Put the tray in a pre-heated oven for 35 minutes. If you are using a standard baking tray, you may want to turn them half way through.

Remove the sweet potato fries from the oven, and serve!

Serving suggestions

I love sweet potato fries with anything. They are a wonderful comfort food for cold winter nights, served alongside any “main”. Whatever I have with them (and usually I have sausages) I always serve them with a portion of soured cream! They also work really nicely alongside my Diet Coke Gammon!

If you are having them as part of a Mexican dish, or you just want to add a bit of zest to your sour cream, zest a lime and mix the lime zest into your sour cream before serving.

Also a big fan of sweet potatoes but want to mix it up? Try these other great recipes.
