I remember how delighted I was when I discovered Sweet Potato Fries, and the recipe on the blog for Spicy Baked Sweet Potato Fries has been a favorite of mine for quite a while now. I still love to make sweet potato fries that way, tossed in a mixture of spices, but recently I started to make plain sweet potato fries and put the spiciness in the dipping sauce. Sometimes I’ll even eat this Spicy Dipping Sauce with Sriracha on (gasp) frozen sweet potato fries like the ones in these photos, although there’s no doubt that from-scratch sweet potato fries are better.

Whether you make my Spicy Baked Sweet Potato Fries or Air Fryer Spicy Sweet Potato Fries, or use frozen ones, this sauce is the perfect dip for sweet potato fries. Fresh lime juice is the secret ingredient that I think makes this over-the-top good! And if you don’t want the carbs from the sweet potatoes fries, enjoy this tasty sauce on roasted veggies for a completely low-carb treat!

Mix together the mayo and sour cream until no lumps appear. Whisk in Sriracha sauce, starting with a tiny amount and then tasting until it’s as spicy as you prefer. I used about 1 tsp. Sriracha sauce, but I’m kind of a lightweight when it comes to spicy foods. Other types of hot sauce could be used, but I love the Sriracha flavor in this.

Then whisk in the fresh-squeezed lime juice, and blend until it’s creamy with no lumps. That’s all! Serve with sweet potato fries and wait for compliments.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Sweet potato fries with a moderate amount of this Spicy Dipping Sauce with Sriracha would be approved for phase 2 or 3 of the South Beach Diet, especially if you make your own sweet potato fries and use light sour cream and light mayo. If you eat it with low-carb vegetables, this could be great for other low-carb eating plans, which would prefer full-fat mayo and sour cream.

  1. Nutritional information for air fryer spicy sweet potato fries

    • Not sure what you mean by that, but I’m not able to provide nutritional information for the recipes for several reason, including the additional time it takes, the difficulty in doing it accurately, and the sheer number of recipes on my site. If you look after the recipe itself, I give two links (where it says “Nutritional Information”) for suggestions of two ways to get that information. That’s all I can do at this time. Thanks for understanding.

  2. recipe omits HOW MUCH lemon juice

    • So sorry about that. I must have skipped that line when I copied it over to the new recipe format. And I was at a lecture so just saw this. Fixed now. I hope you were able to experiment with adding lime juice and get it to work for you.

  3. I think brussels sprouts is genuis; must try!

  4. I usually just mix light mayo and siracha, but yes, it's awesome with roasted cauliflower or Brussels sprouts as well.

  5. Natasha, glad you like it!

  6. This dip is YUMMY!!! I'm waiting on my sweet potato fries to finish cooking, but w/ this sauce I know they'll be fantastic. Thanks so much!!!

  7. Yummy! Sweet potatoes and Sriracha. How scrumptious! Adding sweet potatoes to my grocery list today. 🙂

  8. I used equal parts sour cream, mayo & yogurt & it turned out nicely. A little too much lime for my taste but still very good!

  9. This looks amazing. I LOVE Sriracha. Never imagined you could use it for fries' dipping sauce though.

  10. Heather, welcome, and fun to hear from someone local.

  11. I've been amassing food blogs in my google reader for 2 years now and I just barely stumbled upon a local blog! So glad to see you out there! And this recipe looks delicious. 🙂

  12. I love, love LOVE sweet potatoes and sweet potato fries. That dipping sauce looks delicious.

    The last time I made SP fries, I tossed them with oilive oil and cajun seasoning. That spicy seasoning contrasted with the sweetness of the fry and the lucious caramelization. It is my new go-to way to make them. Ad Emeril said- It really kicked it up a notch.

    Your dipping sauce does too!

  13. I've been out all day today and have been moderating the comments from my iPhone, but just wanted to say that I LOVE all the suggestions for other ingredients or other uses for the sauce.

    And nice to hear that I'm making a few converts for Sriracha too.

  14. Mmm, if you mix sriracha sauce with lots of other sauces, chances are it will be real tasty!

  15. I just did a sriracha fry sauce recipe. I used a little ketchup, mayo and mostly greek yogurt, but I love your South Beach one. The lime is a great idea. In the end, what doesn't taste good with sriracha sauce. I just used my recipe with gilled salmon today for lunch. I bet your version would also taste great on a turkey burger.

  16. Sweet potato fries and sriracha mayo… ahhh devine! You can also throw in some chopped green onions (and a bit extra sriracha) and eat with Cal rolls, use in spicy tuna, hamachi, lobster, etc. handrolls… They are heavenly. (I often skip sour cream, & just mix homemade mayo, sriracha & green onions.) They are great with steamed artichokes too!

    I have lots of sweet potatoes… maybe I'll make the fries this weekend…

  17. This looks yummy and is very timely – I have a bunch of sweet potatoes that I wasn't sure what to do with – having a sauce to "go with" will motivate me to roast them. Also that slaw recipe looks outstanding!

  18. I adore sriracha … and sweet potato fries. I love the idea of using yogurt to make the dip too. Mmmm. Trying this soon!

  19. Gotta try this. I'm really learning to lie Sriachi sauce. Thanks for this recipe.

  20. Hi Kalyn. I love Sriracha Sauce and sweet potatoes. Thanks for an awesome recipe.

  21. Sounds like a lovely combo! I love spicy & sweet.

  22. try adding some thai sweet chili sauce (a la faux bang-bang shrimp from bonefish). it's delish!

  23. Thanks for having this blog! I'm new to SBD, today being my first day on the diet, and have approximately 70 lbs. to lose. I'm excited about finding your blog and will be visiting a lot to use your recipes!

  24. YUM! This looks great! I love sweet potato fries. And I love mayo dipping sauces. And spice! You just made my day!

  25. That sauce sounds wonderful and the fries look absolutely fantastic. I love Sriracha!

  26. Looks fabulous… sorry I haven't been around for awhile, I moved to the US Virgin Islands (I still giggle when I say that) for six months, and it is taking awhile to get settled. But i do think I am caught up, and will be back with new postings…

    Come take a look at my new blogs of Island life!

    And I am needing all the sauce recipes I can find. The prices here are incredible. SOur cream is $3 a container, and dips are all over $5 … saving these

  27. Oh yes! I'm completely addicted to sriracha. And I could all too easily become addicted to sweet potato fries. I love sriracha mixed with Greek yogurt, lime and a bit of soy sauce.

  28. I use sriracha sauce in everything. Thanks for one more idea!

  29. I was also going to suggest subbing Greek yogurt for the sour cream. It's thick and tangy, higher in protein than sour cream.

  30. I wish I could reach in and grab those fries. I would eat every single one. They look soooo good!

  31. Dara, I've really gotten hooked on Sriracha!

    I'm loving SueBob's idea of using plain yogurt in this. If anyone tries it that way, let us know how you like it. (This is why the internet is so great!)

  32. Have you tried it with plain whole-milk yogurt? It seems like that might be great.

    Thanks for the idea.

  33. I have a big bottle or sriracha sauce in my pantry. I am definitely going to try this recipe. Those sweet potato fries look fabulous.
