Ingredients for Arby’s sauce

Seven simple ingredients unlock the creamy, tangy magic behind Arby’s signature sauce.

Ingredient Amount Notes
Mayonnaise 🥛 1 cup High-quality, full-fat preferred
Buttermilk 🥛 ½ cup Full-fat for best texture
Celery Salt 🧂 1 ½ tsp Not regular table salt
Smoked Paprika 🌶️ ½ tsp For that signature Arby’s depth
Garlic Powder 🧄 ½ tsp Freshly ground preferred
Onion Powder 🧅 ½ tsp Adds subtle sweetness
Black Pepper 🌶️ ¼ tsp Freshly cracked for bite

The mayo and buttermilk are non-negotiable for that signature creamy-tangy balance. Duke’s or Hellmann’s mayo works best—avoid the light versions, they won’t give you that rich texture. For buttermilk, full-fat is key—it keeps the sauce luscious without curdling. Celery salt is the magic ingredient here. Morton’s is my go-to, but any brand with a strong celery flavor will do. The smoked paprika gives it that subtle smoky depth that makes it taste like the real deal. Pro tip: if you can’t find smoked paprika, regular paprika plus a pinch of liquid smoke works in a pinch.

No celery salt? Regular salt plus a teaspoon of dried celery flakes (from the bulk section) gets you close. Want extra tang? Add a splash of lemon juice or vinegar—start with half a teaspoon and adjust. The garlic and onion powders are just for depth—skip them if you’re in a hurry, but trust me, they make the difference. For a smoother texture, blend the spices with a pinch of the buttermilk first before mixing everything together. That way, you avoid any gritty bits. And if you’re using store-bought buttermilk that’s past its prime, add a splash of vinegar or lemon juice to sour it up before using.

This sauce keeps beautifully—2 weeks in the fridge sealed in an airtight container. For longer storage, freeze it in ice cube trays, then transfer to a bag. Thaw overnight in the fridge, give it a stir, and it’ll be just like new. The flavor actually improves after chilling, so make it a day ahead if you can. It’s perfect for dipping, sandwiches, or even as a base for crispy cornmeal crusts. Double the batch—you’ll want it on everything.

Step-by-step instructions for Arby’s sauce recipe

Here's how to whip up that iconic Arby’s sauce—creamy, tangy, and packed with the perfect balance of savory and smoky flavors.

1

👨‍🍳 Step 1: Whisk Together the Mayonnaise and Buttermilk

In a medium bowl, combine the 1 cup mayonnaise and 0.5 cup buttermilk. Use a whisk or fork to blend them thoroughly until completely smooth. I like to let the mixture sit for 1-2 minutes—this allows the buttermilk to slightly thicken and mellow out any sharp tang.

The buttermilk adds that signature tangy kick that makes this sauce so addictive. If your buttermilk is too thick, you can thin it slightly with 1 tablespoon water—just enough to make it pourable. This step is all about creating the perfect creamy base that will carry all those bold flavors.

2

🥘 Step 2: Add the Dry Seasonings for Maximum Flavor

Now, sprinkle in the 1.5 teaspoons celery salt, 0.5 teaspoon smoked paprika, 0.5 teaspoon garlic powder, 0.5 teaspoon onion powder, and 0.25 teaspoon black pepper. Use a rubber spatula to gently fold everything together until the seasonings are fully incorporated and no dry spots remain.

Here's the thing—celery salt is non-negotiable. It gives that unique, slightly salty, celery-like flavor that's the hallmark of Arby’s sauce. The smoked paprika adds depth, while the garlic and onion powders provide that subtle sweetness and savory backbone. Don't skip the black pepper—it adds a little bite that makes the whole sauce sing.

3

⏰ Step 3: Let It Rest for Perfect Texture

Cover the bowl with plastic wrap and refrigerate for at least 30 minutes, but I prefer 1-2 hours if you have time. This resting period allows all the flavors to meld together and the sauce to thicken slightly, which is crucial for that perfect consistency when you use it on your crispy cornmeal crust dishes.

Real talk: this step makes a HUGE difference. The flavors develop more complexity, and the sauce becomes more cohesive. If you're in a hurry, you can use it immediately, but I promise the wait is worth it. The sauce should be thick enough to cling beautifully to your food without being gluey.

4

🍽️ Step 4: Adjust and Use Immediately

After resting, give the sauce one final taste. If it needs more saltiness, add a pinch more of the celery salt—this is your chance to fine-tune the flavor. The sauce should be tangy, slightly smoky, and perfectly balanced with a hint of sweetness from the onion powder.

This sauce is best used fresh, so don't make it too far in advance. It's perfect for dipping those crispy cornmeal crust sandwiches, drizzling over roasted potatoes, or even as a creamy dressing for coleslaw. The key to that copycat magic is using high-quality ingredients and letting the flavors develop properly—don't rush it!

Pro Tips For Making Arby’S Sauce

  • STIR GENTLY, THEN REST: Mix the mayo and buttermilk with a rubber spatula—don’t whip it like a cocktail, or you’ll end up with a greasy mess. Once combined, let the sauce sit for 10 minutes before adding spices; this lets flavors meld instead of fighting each other.
  • USE COLD BUTTERMILK: Straight from the fridge, not room temp—cold buttermilk emulsifies better with mayo and keeps the sauce from separating. If you’re in a rush, chill the bowl in the freezer for 5 minutes first.
  • SALT THE CELERY FIRST: Taste the celery salt before adding it to the sauce—store-bought blends vary wildly. Sprinkle a pinch into a spoonful of plain mayo first to gauge strength; adjust if it’s too mild or harsh.
  • SWAP PAPRIKA FOR SMOKE: No smoked paprika? Use half the amount of regular paprika plus a pinch of liquid smoke—just a drop or two, or it’ll taste like a campfire. Add it last and stir very lightly to avoid overpowering the tangy base.

Pro cooking tips for this dish

Perfect Mixing Technique

Use a hand mixer or immersion blender for 30 seconds after combining mayo and buttermilk to eliminate any streaks. I prefer my KitchenAid KSM150PSER for this job—it creates a silky texture without over-aerating.

If you hand-whisk, go slow to avoid incorporating air bubbles that can make the sauce too light. 💛

Celery Salt Substitutes

Can’t find celery salt? Mix 1 tsp regular salt with 1 tsp dried celery flakes (from the bulk spices section) for a close approximation. For extra depth, add ½ tsp celery seed—it’s stronger, so use sparingly.

I’ve also tested 1 tsp Lawry’s Seasoned Salt (celery flavor) with great results. Always taste as you go!

Smoke Enhancement Hacks

Need more smokiness? Add ¼ tsp liquid smoke to the finished sauce for that restaurant-quality depth. For a homemade version, toast ½ tsp smoked paprika in a dry pan for 30 seconds until fragrant, then cool and mix in. This caramelization intensifies the smoky flavor without overpowering the creamy base.

Texture Troubleshooting

If your sauce separates, whisk in 1 tablespoon cold water while mixing vigorously. For a thicker consistency, chill for an extra 30 minutes. Too thin? Add 1 tsp cornstarch mixed with 1 tsp cold water, then stir until thickened.

The ideal texture should be like heavy cream—thick enough to coat but still pourable. ✨

Flavor Development Tricks

For maximum flavor, let the sauce sit overnight before using—this allows the spices to fully infuse. I also recommend adding ½ tsp apple cider vinegar to brighten the tang.

If you’re using this for crispy cornmeal crusts, brush it on in thin layers and broil for 1-2 minutes to create a golden, caramelized finish.

Storage Secrets

Store in an airtight glass container with parchment paper pressed against the surface to prevent a skin from forming. For freezing, portion into 1-tablespoon servings in ice cube trays—thaw directly in the fridge for 4-6 hours.

The sauce keeps its best quality for 2 weeks refrigerated or 3 months frozen. Label with dates to track freshness! 💡

2

Can I make this sauce without celery salt?

Yes! Mix 1 teaspoon regular salt with 1 teaspoon dried celery flakes (from the bulk spices section) for a close substitute. For extra depth, add ½ teaspoon celery seed—just use sparingly as it's stronger. Always taste as you go to adjust the flavor to your preference.

3

How long does this sauce keep in the fridge?

This copycat sauce stays fresh for up to 2 weeks when stored in an airtight container. For best results, press parchment paper directly on the surface before sealing to prevent a skin from forming. The flavor actually improves after chilling, so making it a day ahead is ideal.

4

What's the best way to use this sauce?

This versatile sauce is perfect for dipping crispy cornmeal crust sandwiches, drizzling over roasted potatoes, or using as a creamy dressing for coleslaw. For extra restaurant-style flavor, brush it on crispy chicken before broiling for 1-2 minutes to create a golden caramelized finish.

5

Why did my sauce separate? How can I fix it?

Sauce separation happens when fats and liquids separate. To fix it, whisk in 1 tablespoon cold water while mixing vigorously. For prevention, use room-temperature ingredients and avoid overmixing. If you need a thicker consistency, chill for an extra 30 minutes or add a cornstarch slurry if needed.
