What Sauce Goes With Sweet Potato Fries? ⋆ 8 Winning Combinations ⋆

Crispy sweet potato fries with a nice dipping sauce – what is tastier than that?! Not much, that’s what! And if you already have the perfect recipe for sweet potato fries, chances are you’re now after the ideal dipping sauce for those fries.  

So what sauces go with sweet potato fries? If you like something hot and spicy, then aioli, ranch, sriracha sauce, chipotle lime sauce, or cajun dipping sauce are perfect with sweet potato fries. For something a little milder, try ketchup and Worcestershire sauce or honey mustard sauce. Prefer sweet on sweet? Then a toasted marshmallow dip is another great pairing. 

Quick cheats: instead of making a sauce, you can serve the sweet potato fries with store-bought mayo. 

If you want some extra spice, simply blend in some chipotle or sriracha sauce.  

Can you serve sweet potato fries without a dipping sauce? Absolutely! 

Crispy sweet potato fries with some freshly ground salt (and pepper, if you feel like it) are divine on their own.  

Now, let’s have a look in more detail at the various sauce options for sweet potato fries!

Best Sauces For Sweet Potato Fries (Sweet Potato Fries Sauce Options)

  • Aioli–a creamy, garlicky dream, you really can’t go wrong with aioli (if you like mayo and garlic, that is!)
  • Toasted marshmallow dip–if you have fond childhood memories of marshmallow whip/dip on top of sweet potato mash, then this may be for you.
  • Sriracha sauce–sriracha dipping sauce involves more than just sriracha–by blending it with sour cream or yogurt, as well as some mayo, you get a deliciously creamy sauce.
  • Honey mustard sauce–mustard might not be the first ingredient you think of when contemplating making sweet potato fry sauce, but it works surprisingly well.
  • Chipotle lime dip–South American flavors infuse this sauce.
  • Ketchup and Worcestershire sauce–two classic sauces combined and mixed with some mayo make for an excellent dipping sauce.
  • Cajun dipping sauce–if you love the Cajun kitchen, you’ll love this sauce! 
  • Sriracha and ranch dip–another sauce that calls for combining two popular condiments and turning it into something else entirely

Sweet Potato Fries With Aioli

Garlic meets mayo. Divinity achieved. Sort of. At least if you like garlic and mayo! 

This sauce can also be used as a base for other sauces–I’ve given you some ideas for flavors you can add. For example, add wasabi and turn it into wasabi sauce! 


  • 1+1 Egg + egg yolk at room temperature
  • 1 Tbsp Dijon mustard
  • 2 Tsp lemon juice
  • 1 Cup neutral-flavored oil such as canola or vegetable oil
  • 1 Tsp salt


Step One: Put all the ingredients in a deep bowl, or glass, starting with the egg and egg yolk.

Step Two: Using an immersion blender, blend the ingredients together for about 20 seconds, moving the blender up and down (don’t move it above the surface of the sauce, or it will splatter).

The sauce should have a mayonnaise consistency. If you do not have an immersion blender, use a good old whisk. It will take a bit longer than 20 seconds, but it will work just as well. 

Step Three: Put in a serving bowl, cover, and refrigerate. If stored in an airtight container, it can keep for up to a week, granted you used fresh eggs. 

Note: You can easily alter this recipe by whisking in some extra ingredients. If you want to have alternatives to choose from, it’s easy enough to make several different sauces using the same base. See below. 

  • Truffle & Black Pepper: 1 Cup basic aioli + 2 tsp truffle oil + 2 tsp freshly cracked black pepper
  • Lemon & Dill: 1 Cup basic aioli + juice of half a lemon + zest of one lemon + ¼ cup fresh dill
  • Rosemary: 1 Cup basic aioli + 3 tbsp roughly chopped fresh rosemary + 1 tsp black pepper
  • Smoky Chipotle: 1 Cup basic aioli + 1 chili pepper in adobo sauce (finely chopped), + 1 tsp chipotle chili powder + juice of half a lime
  • Wasabi: 1 Cup basic aioli + 1 tbsp wasabi paste + 1 tsp white wine vinegar

Sweet Potato Fries With Toasted Marshmallow Dip

If you love some marshmallows with your sweet potatoes, then you have to try this marshmallow dip! Perfect if you have a sweet tooth.


  • 10 Marshmallows (you don’t want the flavored kind unless you want your sauce to taste like strawberries or similar!)
  • ¼ Cup heavy cream


Step One: Preheat the oven to 375°F.

Step Two: Line a baking dish with parchment paper. Place the marshmallows on top. Roast in the oven until the marshmallows get that perfect golden brown hue. Note that they’re quick to burn, so keep an eye on them. 

Step Three: As the marshmallows are roasting, heat the cream in a small saucepan over medium heat. 

Step Four: Add the toasted marshmallows to the cream, stirring till combined. Then serve in a heatproof bowl–you want the sauce to be hot when served.

If it goes cold, it starts to stiffen. You can heat it in the microwave (or pan, for that matter) if it gets too cold. 

Step Five: If you feel like adding some decoration, put a marshmallow on top of the sauce and torch it with a small kitchen blowtorch till golden. 

Sweet Potato Fries With Sriracha Dipping Sauce 

Like it spicy? Then you know sriracha sauce.

Once you mix this particular sauce with a bit of sour cream and mayo, or yogurt, however, you have a creamy sauce that works perfectly with the sweetness of sweet potato fries.                                                               


  • ¼ Cup reduced-fat sour cream or Greek yogurt 
  • ¼ Cup light mayonnaise (if you like keeping things light, that is)
  • 1.5 Tsp Sriracha sauce


Step One: Add the sour cream (or yogurt), mayo, and sriracha sauce to a bowl. Stir to combine with a fork. The sauce should be creamy and smooth when done. 

Sweet Potato Fries With Honey Mustard Sauce

Sweet meets heat with this delicious sauce.


  • 3 Tbsp Dijon mustard
  • 3 Tbsp stone-ground mustard
  • 3 Tbsp mayonnaise
  • 4 Tbsp honey
  • ¼ Tsp cinnamon


Step One: Combine all the ingredients in a small food processor and blend. Alternatively, put all the ingredients in a small bowl, using a small spoon or fork to blend them together. Keep in the fridge till serving. 

Sweet Potato Fries With Chipotle Lime Dip

Chipotle and lime go together like…well, the ingredients in South American cuisine.

And these particular ingredients combined happen to make for a beautiful dipping sauce. 


  • 1 ¼ Cup mayonnaise 
  • ½ Lime, juiced
  • 1 Tsp ground chipotle powder
  • ½ Tsp chili powder
  • ¼ Tsp paprika
  • ¼ Tsp cumin
  • ¼ Tsp garlic powder 


Step One: Put all the ingredients in a small bowl and mix together until smooth. Alternatively, use a small food processor, though it really isn’t necessary. Try making the sauce at least an hour before serving so that it gets time to sit. This will help the flavors blend and come out properly. 

Sweet Potato Fries With Ketchup & Worcestershire Dip

Ketchup and Worcestershire sauce come together very nicely in this dipping sauce. 


  • ⅓ Cup mayo
  • ¼ Cup ketchup
  • ½ Tsp Worcestershire sauce
  • ¼ Tsp paprika


Step One: All you have to do is put the ingredients in a bowl and stir till completely combined. Then store covered in the fridge until serving. You can make the sauce in advance or while the fries are baking. 

Sweet Potato Fries With Cajun Dipping Sauce

Cajun foods are yummy, and a Cajun dipping sauce goes really well with sweet potato fries. If you’re missing New Orleans, this sauce might be for you.

Then again, if you’re missing New Orleans, you probably have your own recipe to cook up and don’t need this one… 


  • ¼ Cup mayonnaise
  • 1 Tbsp ketchup
  • 1 Tsp molasses
  • 1 ½ Tsp Cajun seasoning (more or less–you can add more or use less depending on how spicy you want it to be)


Step One: Combine all the ingredients in a bowl. Stir until smooth. You can make it in advance and store it, covered, in the refrigerator. 

Sweet Potato Fries With Cilantro and Lime Dipping Sauce

The flavors of South America come alive in your kitchen when you make this dipping sauce. It goes extremely well with sweet potato fries.   


  • 1 ¼ Cup mayonnaise 
  • ½ Lime, juiced
  • 1 Tsp ground chipotle powder
  • ½ Tsp chili powder
  • ¼ Tsp paprika
  • ¼ Tsp cumin
  • ¼ Tsp garlic powder 


Step One: Put all the ingredients in a small bowl and stir until well combined. Refrigerate for at least an hour before serving–this will allow the flavors to blend properly. 

Sweet Potato Fries With Sriracha Ranch Dip

Some like it hot! And some like ranch. If you like both, this is the sauce for you! It certainly packs a punch, so not for the faint of heart, though you can use less sriracha sauce if you want it a bit milder.

The sour cream adds a nice creaminess, too, which takes some of the edge off the sriracha sauce.  


  • 4 Tbsp sour cream
  • 1 Tbsp ranch seasoning mix
  • 1 Tbsp sriracha hot sauce


Step One: Put all the ingredients in a small bowl and whisk together (or use a small fork or spoon if you don’t have a small whisk at hand). Keep refrigerated until you serve it.

Granted, you use sour cream that isn’t about to go off any time soon; the sauce will last for up to seven days if kept in an airtight container in the fridge.
