Do you love sweet potato fries?

Of course you do! Who doesn’t love them! I have never been able to resist a French fry, if its put in front of me.

Once in a while, I like to change up my French fries.  Remember my sweet potato wedges or butternut squash french fries.

One taste of these sticky sweet potato fries and you will never go back to plain fries again!

Tips for making these fries

  • Make sure you use thick sweet potato fries and not shoe-string cut because they will hold the sauce
  • Since I was short on time, I went with frozen sweet potato fries by Alexia. If you have time, make yours from scratch and use my tips on baking sweet potatoes
  • Don’t mix the sauce and sweet potato fries until you are ready to eat them.  Otherwise, they will get soggy and clumpy
  • Eat these sticky sweet potato fries immediately.   They don’t freeze well
  • You can also use regular potatoes instead of sweet potatoes
  • If some of the sweet potato fries are really long, cut them into half because they will be easier to manage in the wok

Just look at that sticky goodness!!

How these sticky fries came to be!

The other day, I ordered the Chinese broccoli and I had some of that sticky sauce left over on my plate.

On the other side of the table, I had a friend who ordered French fries and let me taste one them.

(Well, technically, it was more like I invited myself to try those fries without asking for permission! But, we are not going to split hairs here.)

There was no ketchup left and I was too lazy to get up for ketchup packets!

So, I dipped them into the sauce left over from my broccoli sauce.

The rest is sweet potato history! Sometimes, laziness does pay off in a big way!
