Applebee's Sweet Potato Fries Dipping Sauce Recipe: Celery-Crunch Creamy Mayo with Zesty Mustard Kick

This Applebee's sweet potato fries dipping sauce brings that signature creamy, tangy kick straight to your kitchen counter—no restaurant trip required. The secret lies in balancing rich mayo with sharp mustard and crunchy celery, creating a sauce that clings perfectly to every crispy fry.

I’ve recreated this version after testing countless batches, ensuring the texture stays smooth yet slightly thick, with just the right amount of zesty bite to cut through the sweetness of the fries.

The foundation of this sauce is simple yet foolproof: mayonnaise, sour cream, and a blend of Dijon mustard and hot sauce for depth. Finely chopped celery adds a subtle crunch and freshness, while a touch of garlic powder and onion powder rounds out the flavor profile.

The key is mixing everything together gently—overworking it can turn the sauce grainy, and we’re aiming for that velvety, restaurant-quality consistency.

What makes this sauce truly special is how it transforms ordinary fries into an indulgent experience. The creamy base coats each fry beautifully, while the mustard and celery bring a bright, almost addictive contrast.

It’s the kind of sauce that disappears faster than the fries themselves, leaving you reaching for more. Best of all, it stays fresh in the fridge for up to a week, ready to elevate any crispy, salty, or sweet dish you’re serving.

Whether you’re hosting a game day gathering or just craving a taste of Applebee’s at home, this sauce delivers that perfect balance of creaminess and zing. The ingredients are straightforward, and the process is quick—just mix, taste, and adjust to your preference. Here’s how to make it, step by step.

Ingredients for applebee's sweet potato fries dipping sauce

Six creamy ingredients, one tangy sauce that’ll make your fries taste like Applebee’s.

The mayo and sour cream are your creamy base—Hellmann’s or Duke’s for mayo, and full-fat sour cream (the good stuff, not the low-fat kind) for that velvety texture. Dijon mustard is non-negotiable here—it’s what gives that signature tang. Trader Joe’s has a great one if you’re not already stocked. Celery is the secret weapon for crunch—fresh is best, but if you’re using pre-chopped, rinse it first to remove any slimy bits. The garlic and onion powders are just a touch, but they round out the flavors perfectly.

No Dijon mustard? Yellow mustard at half the amount works in a pinch, but you’ll lose that sharp depth. Hot sauce can be swapped for hot sauce blend or a dash of cayenne, but Frank’s RedHot is the real deal. Celery too watery? Drain it and pat dry before chopping. Want extra zing? Add a pinch of smoked paprika or a dash of Worcestershire sauce (if you’re not avoiding it). The lemon juice is key—freshly squeezed brightens everything up, but bottled works if you’re in a rush.

This sauce keeps like a dream—5-7 days in the fridge, sealed tight. I like to portion it into small jars so it’s ready whenever fries hit the table. If it gets too thick, just stir in a splash of milk or water. Pro tip: double the batch—you’ll want leftovers, trust me. Freezes beautifully too, though texture might separate slightly after thawing. Just give it a quick stir before serving.

Step-by-step instructions for Applebee's-inspired sweet potato fries dipping sauce

This creamy, crunchy sauce comes together in minutes with just a few simple steps.

Start by cutting the 3 whole celery stalks into very small pieces—think almost like a fine dice. I like to cut them into ¼-inch pieces first, then chop those smaller bits. This ensures you get that signature celery crunch without any large chunks. Fresh celery works best here, as frozen or canned won't give the same texture.

Once chopped, give the celery a quick rinse under cold water to remove any dirt or sand, then drain well in a colander. Pat it dry with a paper towel—this prevents excess moisture from making your sauce watery later. Set the chopped celery aside in a small bowl.

In a medium bowl, combine the 0.75 cup mayonnaise and 0.5 cup sour cream. Use a whisk or a fork to blend them together until completely smooth. I like to mix for about 30 seconds to make sure there are no streaks of either ingredient. This creamy base is what gives the sauce its signature texture, so don't skip this step.

Next, add the 2 tbsp Dijon mustard and 1 tbsp hot sauce to the bowl. Stir well to incorporate fully. The Dijon mustard adds a tangy depth, while the hot sauce gives that signature kick. Taste a small spoonful at this point—you should feel the sharpness of the mustard and the heat from the hot sauce, but the mayo and sour cream should still dominate.

To the bowl, add the 0.5 tsp garlic powder, 0.5 tsp onion powder, 0.25 tsp salt, and 0.25 tsp black pepper. Stir everything together until the seasonings are evenly distributed. These dry ingredients add subtle layers of flavor that balance the richness of the mayo and sour cream.

Finally, stir in the 1 tbsp lemon juice. This brightens up the sauce and cuts through the creaminess just enough to keep it from feeling too heavy. The lemon juice also helps to preserve the freshness of the ingredients, so don't skip it.

Now, gently fold the chopped celery into the sauce using a spatula. Be careful not to overmix—you want the celery pieces to stay intact for that satisfying crunch. Once everything is combined, give the sauce another taste. If it needs more salt, add a pinch at a time. If it needs more heat, add a tiny bit more hot sauce.

Let the sauce sit for 5 minutes before serving. This gives the flavors time to meld together, and it also allows the celery to soften just enough to release its juices into the sauce. The result should be a creamy, slightly tangy, and crunchy dip that pairs perfectly with sweet potato fries.

For the best texture and flavor, transfer the sauce to an airtight container and refrigerate for at least 30 minutes before serving. Chilling allows the flavors to fully develop and ensures the celery stays crisp. If you're serving it immediately, at least let it sit in the fridge for 10 minutes to take the edge off the creaminess.

When ready to serve, give the sauce one last stir to redistribute the celery. The sauce should be thick but still spreadable—if it's too thick, add a splash of milk or water to loosen it. Serve it alongside your sweet potato fries, and enjoy the perfect balance of creamy, tangy, and crunchy flavors.

Dietary considerations for this dish

Dairy-Free Option

Swap the mayo and sour cream for vegan mayonnaise like Hellmann's Vegan and full-fat coconut yogurt (unsweetened). The coconut yogurt adds a subtle tang that mimics sour cream beautifully. For extra creaminess, blend ½ cup silken tofu with 1 tbsp lemon juice and use that instead of sour cream.

The celery and mustard flavors stay intact, so the sauce still delivers that signature crunch and zing. 🌱

Gluten-Free Adaptation

This sauce is naturally gluten-free, but always double-check your ingredients. Dijon mustard is typically gluten-free, but some brands contain additives. Look for certified gluten-free options like Annie's or Maille. The hot sauce should also be gluten-free—Frank's RedHot is safe, but verify labels if using other brands.

The celery, garlic powder, and onion powder are all gluten-free staples, so no modifications are needed there. ✨

Lower-Carb Version

To reduce carbs, skip the celery and replace it with finely chopped green onions (about 2 tbsp) for a milder crunch. You can also add 1 tbsp chopped fresh dill for a bright, herby note.

The sauce will still be creamy and tangy, but with fewer carbs. For extra flavor without the carbs, stir in 1 tsp apple cider vinegar to enhance the tang. 💪

Spicy Adjustments

If you love heat, increase the hot sauce to 2 tbsp or add ½ tsp cayenne pepper for a smoky kick. For a smoky flavor without extra heat, use ½ tsp smoked paprika instead.

If you're sensitive to spice, reduce the hot sauce to ½ tbsp and add ½ tsp honey to balance the tang. Always taste as you go—adjust gradually! 🌶️
