Cajun Dipping Sauce for Sweet Potato Fries: Ready in No Time

Preview: This Cajun Dipping Sauce recipe is made with creamy mayonnaise and ketchup spiced with Cajun seasoning and a hit of molasses. Good with sweet potato fries.

Do you love condiments? We are the “condiment family” according to my daughter-in-law. Before she said that, I thought we were normal (at least in public).🤔

Maybe she’s right. We have a favorite condiment for almost everything we eat that doesn’t come with its own sauce.

ingredients need for Cajun Dip include mayonnaise, catsup, and Creole seasoning

Up until now, sweet potato fries had us stumped. We tried spicy catsup, ranch dressing, cinnamon-sugar, honey, honey-dijon dressing, etc. In short, we experimented with the obvious and not-so-obvious. Nothing did it for us.

Just when I was about to give up, I found this delicious dip in a magazine. It was the answer to our trivial condiment issue.

If you also eat sweet potato fries, I think you will appreciate this easy Cajun Dip! Cajun seasoning adds a kick. Molasses sweetens the mix. It’s the perfect combination.

Ingredients and substitutions:

  • MAYONNAISE: Use good quality mayonnaise. I like olive oil mayonnaise because of the flavor and slightly fewer calories. If you want to make your own, here’s a recipe for homemade mayonnaise.
  • KETCHUP: Catsup or ketchup makes anything better. If you happen to have a bottle of spicy ketchup in the pantry, that would be even better.
  • CAJUN OR CREOLE SEASONING: We always have a green jar of Tony Chachere’s Creole Seasoning on hand. I haven’t tried any other brands, but they should be fine.
  • MOLASSES: Molasses has a unique flavor that’s hard to imitate. Honey or brown sugar could be used instead. Maple syrup is another idea, but it will make your dip runnier than using molasses.

What can I serve this sauce with?

How long will this Cajun Dipping Sauce stay fresh?

The dip will keep for 5-7 days if using commercial mayonnaise. Homemade mayonnaise will not stay fresh quite as long.

Hi- Just found your blog and am lovin' it!!

My favorite condiment for sweet potatoes is a a greek yogurt dip sole by costco. I think it's just called "Jalepenjo Dip". It's super creamy becuse of the greek yogurt with few calories, tons of taste, and the protein we need (we aren't big meat eaters). We put it on everything, burritos, wraps, turkey burgers, ect. Hope you can find it at your costco!

I love sweet potato fries with BBQ sauce! {It's another great mix of sweet and spicy.} Depending upon the particular sauce I'm using, I will sometimes mix a bit of ketchup in as well... but with so many different types of BBQ sauce, there are quite a few flavor combinations to enjoy!
