Happy FRI-DAAAAAAY. I really believe they named Friday for a reason due to the fact that on the weekend, you can eat ALL the french fries you want and not feel an ounce of guilt. I’m just saying. Anyway – these crispy cajun sweet potato fries ARE LYFE. They’re crispy, seasoned with a homemade cajun spice blend and they have the easiest dipping sauce ever that will make you swoon.

I used to hate sweet potatoes. I swear, I feel like half of my blog posts are me telling you how I used to hate a specific food (brussel sprouts, coconut, cauliflower etc.) and now I love it. I used to think they were way too sweet and mushy. Like baby food. Blegh.

Then….I met my husband. And learned the joy of baking your own sweet potatoes and turning them into FRIES. And said fries don’t turn out mushy OR too sweet. In fact, they’re crunchy and deliciously flavorful. Is there a person on this Earth who doesn’t like fries? If so, I feel so sorry for those poor souls.

Anyway, if you didn’t already know, sweet potatoes are SUPER good for you. Packed with nutrients, lots of beta carotene/vitamin A (good for healthy skin and eye health), vitamin C and dietary fiber!

And with this recipe, you get to dip them in the most amazing aioli. Which we all know is just a fancy term for mayonnaise, right? K, just checking. Aioli sounds cooler anyway.

This is a pretty straight forward recipe. More details are down below – but the basics are:

  1. Cutting the sweet potatoes into long, thin strips (aka they need to look like fries.)
  2. Make super easy homemade cajun seasoning filled with spices you probs already have in your pantry.
  3. Coat the taters with said seasoning.
  4. Bake.
  5. Mix mayo a la other things in a bowl.
  6. Eat. Dip. Repeat.

Easy enough for a Friday, right? You made it to the end of the week, my friend! Proud of you. Cheers to alllll the fries and the weekend!!
