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 a 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.

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, you will appreciate this easy Cajun Dip! Cajun seasoning adds a kick. Molasses sweetens the mix. It’s the perfect combination.

“This recipe is great! And so easy too. I am eating it with yam fries (and veggies) right now. Word of caution though: don’t over-measure the molasses, too much throws the taste off a bit.” — BRETT


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 have a spicy ketchup bottle in the pantry, that would be even better.
  • CAJUN OR CREOLE SEASONING: We always have a green jar of Tony Chachere’s Creole Seasoning. 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 molasses.

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 for quite as long.

    I like honey dill dip or chipotle mayo with my sweet potatoes 🙂

    1. Both sound fantastic Cassandra.

  2. We enjoy Orange Marmalade with out sweet potato fries, slightly warmed to thin. Yummy!

  3. 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!

    1. Andy,
      Love, love Costco. Adding Jalapeno Dip to the list for my next visit. Thanks for the tip.

  4. 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!

    1. Hi April,
      What an easy idea for a dip! Gotta give it a try. Thanks for writing.

  5. This sounds great. Thanks.

  6. Hi, I stumbled onto your post and need to share our favorite dips for sweet potato fries as no one had mentioned them. I love them dipped in honey mustard and my daughter mixes ketchup and ranch dressing together for her own “secret” sauce (not so secret now, oops!). I am definitely going to try your recipe next!

    1. Jen,
      I have never mixed ketchup and Ranch but I often mix ketchup and mayo or tartar sauce. I can imagine it is quite tasty. Thanks for writing.

  7. I love these and found a great dip plus something a little bit sweet….I toss them in Coconut oil before placing in oven. When done I drizzle a bit of organic honey over them and lightly sea salt them. Dip is home made mayo with olive oil, sweet chili sauce, and a dash of pepper. So Good♥

    1. Kimberly, Your method sounds fabulous. The dip sounds easy and good too. I’ll let you know when I try it. pr

  8. Fry sauce is generally ketchup mustard and mayo with occasional spices here and there. You might look up a recipe online then tweek it to your preferences.

  9. Push comes to shove, I bet you could find it on Amazon.com or the like. It can be addictive, watch out!

  10. Sounds a lot like Fry Sauce, a tasty dip we eat often in Wyoming/Utah. Best store bought kind is Some Dude’s Fry Sauce, but I’m sure you can find great recipes online. It is the only thing we have found that matches great with sweet potato fries, though I have been known to dip them in thinned cranberry sauce with a little pumpkin pie spice added, and sometimes celery and green apple to make a scoopable dip.

    1. Mandi,
      I’ve never heard of Fry Sauce but I’m going to look for it. Wonder if they sell it in Texas. paula

  11. I ordered sweet potato fries out one day and they were served with apple butter to dip them in.

    1. Can’t wait to try this. Thanks Ginger. pr

  12. Found your through pinterest. I’m making your baked spaghetti with cream cheese for dinner tomorrow night, it just looks so good! So excited when I saw this recipe- I have a bag of Costco sweet potato fries in the freezer right now so I can’t wait to try this. I usually eat mine dipped in a balsamic vinegar reduction, I like the tangy with the sweet.
    Looking forward to trying many more of your recipes! Thanks!

  13. Another great one is a 1:2 mix of sour cream and mayo, with a sprinkle of paprika, s&p, and fresh chopped cilantro. YUM.

  14. That recipe is great! And so easy too. I am eating it with yam fries (and veggies) right now. Word of caution though: don’t over-measure the molasses, too much throws the taste off a bit.

    1. Haven’t tried this dip with other veggies but I can imagine it’s very tasty. Thanks for the word about the molasses. That stuff is strong.

  15. You know a great dip for sweet potatoes? Horseradish Mayo! It’s so good. All it is, is really horseradish, mayo (adjust to preference of tang and heat), salt, and maybe a tiny squeeze of lemon. So good!

    1. This sounded so good, we tried it tonight for dinner with sweet potato fries from Costco. You are right! Delicious. Love it. Thanks so much for leaving a comment!

  16. hmmm maybe i will try this this weekend. I hadn’t really thought about it but i don’t really love the dips i’ve had for sweet potato fries. I’d usually end up just eating them straight. come to think of it I haven’t had sweet potato fries in ages.

  17. thanks for coming up with a condiment for sweet potato fries! yum, yum!

  18. I’ll have to look for the sweet potato fries at Costco. Can’t believe I missed them, we love sweet potatoes at our house:) I’m printing out the dip recipe as I type.

  19. Sounds perfect for sweet potato fries. I use Trader Joe’s or homemade, I ‘ll have to try the Costco ones.
    Mimi

  20. I love sweet potato fries. My boyfriend doesn’t like them as much as I do, but he loves Cajun flavors, so this would be the perfect way to serve them.

  21. Such an easy dip (I’m avoiding the condiment word). I’ve made sweet potato fries before (baked) and loved them… reminds me to get that recipe out again! Perfect flavor to pair with the potatoes – and molasses (that must be the secret ingredient)!
