I don’t know about y’all….but I can eat french fries ANY TIME. 

They’re just the perfect snack or side dish. They’re crispy, salty and hello, they’re vegetables! Win win win! These Cajun Sweet Potato fries are no exception! Let me tell you why!

Why You’ll Love These Fries: 

They’re crispy, seasoned with a homemade cajun spice blend and they have the easiest dipping sauce ever that will make you swoon.

I met Ben (my husband) in college 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 🙂

It’s creamy and a little spicy and the perfect vehicle to slather these fries in. 

This is a pretty straightforward recipe. It takes just a few minutes to slice the potatoes up and then just 40-45 minutes to bake them! Easy peasy. So let’s get into what you need to make them! 

Ingredients You Need: 

Sweet Potatoes – of course! Be sure to use sweet potatoes that are the same size so that when you slice them, they will cook evenly!

Avocado Oil – You can also use olive oil if needed. 

Homemade Cajun Seasoning (garlic powder, salt, pepper, cayenne pepper, dried thyme paprika) – a MUST! This homemade seasoning is simple and so easy. 

Mayonnaise – my go-to is Duke’s mayo!

Lemon, hot sauce, garlic powder, salt and pepper – needed for the spicy aioli!

Making Sweet Potato Fries in 4 Simple Steps: 

  1. Preheat the oven to 400 degrees. Using a sharp knife, carefully slice the sweet potatoes into long thin fries. See photo here: sliced raw sweet potato fries in a metal bowl
  2. In a small bowl, mix together the spices for the cajun spice blend. Add the sliced fries to a large sheet pan. Add 2 tbsp of avocado oil and rub them with your hands to make sure each one is coated! Using a spoon, sprinkle the cajun seasoning on top of the fries to make sure they’re evenly coated and then use your hands to rub it all in! 
  3. Pop the fries in the oven and bake for 40 minutes, flipping them halfway! If desired, for additional crispiness at the end, place the oven on broil for 1-2 minutes. before and after side by side pics of sweet potato fries on the sheet pan
  4. Once the fries are done, quickly mix the ingredients for the spicy aioli together and you’re ready! Add more salt if desired on top of the fries and dig in!

Best Tips for Baking Sweet Potato Fries: 

When you are adding the sweet potato fries onto the sheet pan, be sure and spread them out/make sure they aren’t touching if possible. 

Like I said earlier, be sure to slice them all around the same width/length so that they cook evenly. 

Be sure to make sure that the oil and cajun spice blend really coat ALL of the fries evenly!

To ensure ultra crispiness, if you do place the oven on broil, watch it CLOSELY! You don’t want to accidentally burn the fries. I recommend not letting them broil for more than 2 minutes. In fact, I recommend setting a timer for 1 minute, ha! 

What to Serve Sweet Potato Fries With: 

Easy Black Bean Burgers – these would make the perfect vegetarian main dish for these sweet potato fries!

Gouda Apple Pork Burgers – these burgers are so rich! The fries would be the perfect pairing! 

Ground Chicken Tacos with Chipotle Crema – if you’re looking for a side dish for tacos, these would be perfect!
