Do you love a good dipping sauce?
If you’re anything like us, condiments are a must. My daughter-in-law once called us the “condiment family,” and honestly, she’s not wrong! We’ve got a favorite sauce for just about everything—except sweet potato fries. Until now.
After trying everything from ranch to honey to spicy ketchup, nothing quite hit the mark. Then I stumbled on this Cajun sauce in a magazine, and let me tell you, it was a game-changer!
Cajun seasoning brings the heat, molasses adds a little sweetness, and the creamy base ties it all together. If you love dipping, this one’s for you!
Ingredients & Substitutions
MAYONNAISE: Full-fat mayo gives the best body; olive-oil mayo works for a lighter option; Make your own mayo
KETCHUP: Adds sweetness and acidity; spicy ketchup is a fun swap
CAJUN SEASONING: Any Cajun or Creole blend works (Tony Chachere’s is a favorite)
MOLASSES: Just a touch for depth; substitute honey or brown sugar if needed (maple syrup will thin the sauce)
This Cajun sauce isn’t just for sweet potato fries—try it with:
- Sweet potato chips
- French fries or potato wedges
- Fresh veggies
- Squash patties or Jalapeño hushpuppies
- Fried shrimp or fish

I like honey dill dip or chipotle mayo with my sweet potatoes 🙂
Both sound fantastic Cassandra.
We enjoy Orange Marmalade with out sweet potato fries, slightly warmed to thin. Yummy!
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!
Andy,
Love, love Costco. Adding Jalapeno Dip to the list for my next visit. Thanks for the tip.
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!
Hi April,
What an easy idea for a dip! Gotta give it a try. Thanks for writing.
This sounds great. Thanks.
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!
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.
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♥
Kimberly, Your method sounds fabulous. The dip sounds easy and good too. I’ll let you know when I try it. pr
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.
Push comes to shove, I bet you could find it on Amazon.com or the like. It can be addictive, watch out!
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.
Mandi,
I’ve never heard of Fry Sauce but I’m going to look for it. Wonder if they sell it in Texas. paula
I ordered sweet potato fries out one day and they were served with apple butter to dip them in.
Can’t wait to try this. Thanks Ginger. pr
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!
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.
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.
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.
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!
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!
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.
Yum in every way!
thanks for coming up with a condiment for sweet potato fries! yum, yum!
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.
Sounds perfect for sweet potato fries. I use Trader Joe’s or homemade, I ‘ll have to try the Costco ones.

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.
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)!
