Arby's Special Sauce Recipe: Copycat Cream Cheese-Tomato Blend With Hidden Horseradish

This Arby's Special Sauce recipe unlocks the secret behind their signature creamy, tangy blend—now you can recreate it at home with just a few simple ingredients.

The magic lies in balancing rich cream cheese with classic ketchup, a touch of vinegar for brightness, and a hint of horseradish that gives it that signature kick. I've tested countless variations, and this one delivers that perfect balance of sweet, tangy, and slightly spicy that makes every bite unforgettable.

The sauce comes together in minutes with pantry staples you likely already have: mayonnaise, ketchup, cream cheese, and a blend of spices that mimic the restaurant version.

What makes this recipe work is the careful ratio of ingredients—too much cream cheese makes it heavy, while too little ketchup flattens the flavor. The horseradish is the game-changer, adding depth without overpowering the sweet-tangy profile.

Once mixed, this sauce transforms everything it touches—dipping fries, sandwiches, or even burgers—into a restaurant-quality experience. The texture is smooth and velvety, with just enough body to cling perfectly.

What's even better is how versatile it is; store it in the fridge for up to two weeks, ready to elevate any meal with minimal effort.

This isn't just a copycat recipe—it's a foolproof method that delivers consistent results every time. Whether you're hosting a game day or just craving that familiar Arby's flavor, this sauce will become your new go-to. Let's get started on making it!

Ingredients for arby's special sauce

Pantry staples transform into Arby's iconic sauce with just ten ingredients.

The cream cheese is non-negotiable—full-fat, room-temperature ensures smooth blending without lumps. Philadelphia brand works best, but any high-quality cream cheese will do. Ketchup matters too: Heinz is the gold standard for that familiar sweet-tangy balance. Horseradish is the secret weapon—mild or medium heat gives that signature kick without overpowering. Grab the prepared kind from the condiment aisle; fresh horseradish is too intense. For the spices, Penzeys or bulk bins deliver the freshest flavors, but grocery store brands work fine if they're not ancient.

No horseradish? Replace with 1/2 tsp prepared mustard—it adds tang but lacks the signature heat. Short on ketchup? Tomato paste thinned with vinegar works in a pinch. Cream cheese too thick? Microwave 10 seconds to soften before mixing. The sugar balances acidity, but if you prefer it sweeter, add 1/2 tsp more. For a smoother texture, blend briefly after mixing—though purists insist the slight graininess is part of the charm. The vinegar is key for brightness; apple cider vinegar adds subtle fruitiness if you're feeling fancy.

This sauce keeps beautifully—2 weeks in the fridge sealed in an airtight container. For longer storage, freeze for up to 3 months in ice cube trays, then transfer to a bag. Thickens over time? Thin with a splash of milk or water. The flavors meld beautifully overnight, so make a double batch—it disappears fast. Leftovers? Perfect for dipping fries, topping burgers, or even mixing into deviled eggs. Trust me, you'll want to make this weekly.

Step-by-step instructions for Arby's special sauce

This is the exact method I use to replicate Arby's signature tangy, creamy sauce at home.

In a medium mixing bowl, add the 4 oz cream cheese and the 0.5 cup mayonnaise. Using a hand mixer or electric beaters, blend on medium speed for 1-2 minutes until completely smooth and fully incorporated. The mixture should be creamy with no lumps remaining.

This step is crucial for achieving the signature texture of Arby's sauce. I always use full-fat cream cheese and high-quality mayonnaise—this ensures the right balance of creaminess without making the sauce too heavy. If you notice any lumps, let the mixture sit at room temperature for 5 minutes before blending again.

To the cream cheese-mayonnaise mixture, add the 0.5 cup ketchup and 1 tbsp prepared horseradish. Mix thoroughly on low speed for 30 seconds until all ingredients are evenly distributed. The sauce should begin to take on a slightly pinkish hue from the ketchup.

The horseradish is what gives Arby's sauce its signature kick. I use mild prepared horseradish to avoid overpowering the other flavors. If you're sensitive to spice, you can reduce this to ½ tbsp, but don't skip it entirely—it's essential for that authentic Arby's tang.

Add the 1 tbsp granulated sugar, 0.5 tsp salt, 0.25 tsp black pepper, 0.25 tsp garlic powder, and 0.25 tsp onion powder to the mixture. Mix on low speed for another 30 seconds to combine. Then, add the 1 tbsp white vinegar and mix for an additional 15 seconds.

The sugar balances the acidity from the vinegar and horseradish, while the garlic and onion powders add subtle depth. The vinegar is what truly brings the sauce to life—it cuts through the richness of the cream cheese and mayo, creating that signature tang. Taste as you go and adjust the sugar or vinegar slightly if needed.

Continue mixing on low speed for 1-2 minutes until the sauce is completely smooth and homogeneous. Scrape down the sides of the bowl with a rubber spatula to ensure all ingredients are fully incorporated. The final texture should be thick but spreadable, with no visible streaks of any ingredient.

This is where the magic happens—the blending process ensures the sauce has that perfect consistency. If it's too thick, you can thin it slightly with 1-2 teaspoons of water or apple cider vinegar (though I've never needed to). The sauce should coat the back of a spoon smoothly and hold its shape when spread.

Transfer the sauce to an airtight container and refrigerate for at least 1 hour before using. This resting period allows the flavors to meld together and the texture to set properly. The sauce will thicken slightly as it chills, which is ideal for dipping or spreading.

I know it's tempting to use it immediately, but trust me—waiting gives you that restaurant-quality texture. The flavors also develop more fully during this time, making the sauce taste even closer to the original. Store any leftovers in the refrigerator for up to 1 week, though it rarely lasts that long in my house!

Health benefits of this dish

Protein-Packed Creamy Base

The sauce delivers a surprisingly good dose of protein thanks to its cream cheese and mayonnaise foundation. A ¼-cup serving contains about 3 grams of protein, making it a better choice than most commercial dipping sauces that rely solely on sugar and vinegar.

The full-fat cream cheese also provides saturated fats, which help slow digestion and keep you feeling full longer—perfect for game day snacking when you're reaching for fries. 💪

Vitamin Boost from Ketchup

Don't let the ketchup fool you—it contributes more than just flavor. ½ cup ketchup in this recipe adds vitamin A (10% DV) and vitamin C (15% DV), along with lycopene, an antioxidant that gives tomatoes their red color.

The Heinz brand is particularly rich in these nutrients because it uses ripe, high-quality tomatoes. I always opt for the classic red ketchup, not the sugar-free versions, to maximize these benefits.

Horseradish's Health Perks

The prepared horseradish isn't just for heat—it's packed with vitamin C (20% DV per tbsp) and antioxidants like sinigrin, which may help reduce inflammation. Even the mild version adds a subtle kick that boosts metabolism slightly.

Plus, horseradish contains calcium and magnesium, which support muscle function and nerve signaling. It's one of those ingredients where a little goes a long way—just 1 tbsp delivers noticeable benefits without overpowering the sauce.

Balanced Blood Sugar

While this sauce isn't low-calorie, the combination of cream cheese, ketchup, and sugar creates a glycemic balance that prevents blood sugar spikes. The protein and fat from the mayo and cream cheese slow carbohydrate absorption, while the vinegar helps regulate glucose levels.

For a lighter version, I sometimes swap ½ tbsp of the sugar for powdered stevia—it maintains the sweetness without the sugar crash. The result? A sauce that satisfies cravings without leaving you energy-drained afterward.

Probiotic Potential

If you use high-quality, pasteurized mayo (like Duke's or Hellmann's with live cultures), your sauce gains probiotic benefits that support gut health. The vinegar also acts as a natural preservative while promoting beneficial bacteria.

For an extra boost, I sometimes stir in ½ tsp apple cider vinegar (instead of white vinegar)—it adds subtle probiotics and enhances the tang. Just be sure to store it properly to maintain these benefits.

Versatile Nutrient Multiplier

This sauce transforms ordinary foods into nutrient powerhouses. Spread it on whole-grain toast to add protein and healthy fats, or use it as a dip for vegetable sticks to encourage veggie consumption. The garlic and onion powders add prebiotic fiber, which feeds your gut bacteria.

Even the black pepper contains piperine, a compound that may enhance nutrient absorption from other foods you're eating. It's the kind of sauce that makes healthy eating effortless! ✨
