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.
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 chips or 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?
- Sweet potato fries
- French fries
- Fresh veggies
- Squash patties
- Fried shrimp
- Any fried fish
- Jalapeño hushpuppies

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.
