Ingredients for what is arby's red ranch sauce
Ten ingredients transform into Arby's signature creamy, tangy sauce with that secret buttermilk punch.
| Ingredient | Amount | Notes |
|---|---|---|
| Buttermilk 🥛 | ½ cup | Full-fat preferred for creaminess |
| Mayonnaise 🥫 | ½ cup | Duke's or Hellmann's recommended |
| Granulated Sugar 🍚 | 1 tbsp | Adjust to taste for sweetness |
| Distilled White Vinegar 🍶 | 1 tbsp | Ensures proper tanginess |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Onion Powder 🧅 | 1 tsp | Diamond Crystal brand ideal |
| Smoked Paprika 🌶️ | ½ tsp | For signature smoky depth |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked for best flavor |
| Salt 🧂 | ½ tsp | Kosher or sea salt preferred |
| Water 💧 | ¼ cup | For thinning if needed |
The buttermilk is non-negotiable—it's what gives this sauce that signature tang. Full-fat works best—skip the low-fat version, trust me. Grab Duke's mayonnaise if you're near a grocery store, but any good-quality mayo will do. For the smoked paprika, Penzeys or Trader Joe's carry the best varieties. The garlic and onion powders should be fresh-ground if possible, but pre-ground works in a pinch. I always double-check the vinegar label—distilled white is key here. No shortcuts on the sugar; granulated is best for proper dissolution.
No buttermilk? Substitute plain yogurt with 1 tsp lemon juice for tang. Out of smoked paprika? Regular paprika plus a pinch of liquid smoke mimics the flavor. Want it sweeter? Add another teaspoon of sugar. The water is there as an emergency thin—this sauce should be thick but pourable. Hellmann's mayo works too, but Duke's has that extra richness. Pro tip: blend the buttermilk and mayo first—this is where the emulsification magic happens. If you rush it, you'll get lumps. And no, you can't skip the vinegar—it's what balances the sweetness and keeps the sauce from tasting flat.
This sauce keeps beautifully in the fridge for up to 1 week, sealed tightly in an airtight container. The texture actually improves after the first day as everything melds. For longer storage, freeze in ice cube trays—perfect for single servings. Reheat gently in the microwave, stirring every 20 seconds to maintain that creamy consistency. Leftovers? I always portion mine into small jars—one for dipping, one for sandwiches. The buttermilk might separate if stored too long, so give it a quick whisk before using.

Step-by-step instructions for Arby's red ranch sauce
Here's how to recreate that signature creamy, tangy sauce with a buttermilk secret that makes all the difference.
Whisk Together the Base Ingredients
In a medium bowl, combine the 0.5 cup buttermilk and 0.5 cup mayonnaise using a whisk or electric mixer. The buttermilk is crucial here—it creates that signature tangy depth that sets this sauce apart from regular ranch. Mix these two ingredients until they're completely smooth and fully incorporated, which should take about 30 seconds with a whisk or 10 seconds with an electric mixer.
I like to use a rubber spatula to scrape down the sides of the bowl at this stage, ensuring no streaks remain. The mixture should look uniform and slightly thick, but still pourable. This is your foundation, so take your time here—rushing will leave you with an uneven texture later.
Add Dry Seasonings and Sweetener
Next, add the 1 tablespoon granulated sugar, 1 teaspoon garlic powder, 1 teaspoon onion powder, 0.5 teaspoon smoked paprika, 0.5 teaspoon ground black pepper, and 0.5 teaspoon salt to the bowl. The smoked paprika is what gives this sauce its distinctive Arby's flavor profile—don't skip this or use regular paprika. Mix all the ingredients together until they're completely dissolved and evenly distributed throughout the mixture.
At this point, you should notice the sauce starting to take on a slightly darker color from the smoked paprika. The sugar will help balance the tanginess from the vinegar we're about to add, while the garlic and onion powders provide that classic savory depth. Give it a taste at this stage—you should detect a mild sweetness and a subtle smokiness, but it's not fully balanced yet.
Incorporate the Vinegar and Thin as Needed
Add the 1 tablespoon distilled white vinegar and mix thoroughly. This is where the sauce gets its signature tangy kick. The vinegar should cut through the richness of the mayonnaise and buttermilk, creating that perfect balance between creamy and tangy. You might notice some small curdling at this point—that's normal and actually adds to the authentic texture.
If the sauce is too thick for your liking, gradually add the 0.25 cup water one tablespoon at a time, mixing well after each addition. You want a sauce that's thick enough to cling to fries or chicken but still smooth and pourable. The consistency should be similar to heavy cream—thick but not gloopy. Taste again now; you should get that perfect balance of creamy, tangy, and slightly sweet with a hint of smokiness.
Rest and Adjust the Seasoning
Cover the bowl and let the sauce rest at room temperature for 15-20 minutes. This resting period allows all the flavors to meld together and the seasonings to fully dissolve. Don't skip this step—it makes a noticeable difference in the final product. While it rests, give it a stir every few minutes to prevent any separation.
After resting, give the sauce one final taste and adjust the seasoning if needed. You might need a touch more salt to enhance the flavors, or perhaps a bit more vinegar if you want it more tangy. Remember, the sauce will continue to develop flavor as it sits, so if possible, let it rest for another 30 minutes before serving. This sauce tastes even better after it's had time to fully develop its complex flavors.
Serve Immediately or Store Properly
Serve the sauce immediately for the best texture and flavor experience. It's perfect for dipping fries, chicken tenders, or even as a sandwich spread. If you need to store it, transfer to an airtight container and refrigerate for up to 5 days. The sauce will thicken slightly in the fridge, so give it a good stir before serving and thin with a splash of water or milk if needed.
For the absolute best results, use this sauce within 24 hours of making it. The freshness really makes a difference in that creamy, tangy balance. If you're making it ahead for a party, consider making it the night before and letting it sit overnight in the fridge—this allows all the flavors to fully develop and intensify.
Pro Tips For Making What Is Arby'S Red Ranch Sauce
- STIR GENTLY, NOT VIGOROUSLY: Mix the buttermilk and mayo by hand with a spatula—no blender. I learned this the hard way after whipping in air and ending up with a sauce that separated like a sad salad dressing. Keep it slow and steady.
- USE COLD INGREDIENTS: Pull the buttermilk and mayo straight from the fridge—room temperature makes the sauce split faster than a bad relationship. Cold ingredients blend smoother and stay stable longer, especially when you’re adding vinegar later.
- MEASURE VINEGAR PRECISELY: Distilled white vinegar is the tangy glue here, but too much turns your sauce into a science experiment. Stick to the recipe’s exact amount (usually 1-2 teaspoons) and taste as you go—you can always add a pinch more, not fix an overpowering bite.
- SWAP SUGAR FOR HONEY (OPTIONAL): Granulated sugar gives a clean sweetness, but honey adds depth without crystallizing. If you’re short on sugar or want a smoother texture, replace half with the same amount of honey—just warm it slightly first to dissolve into the mayo.

Freezer-Friendly Portions
Freeze leftover sauce in ice cube trays for easy single-serving portions. Thaw overnight in the fridge and use as needed for dipping or drizzling. This is perfect for meal prep—just grab a cube and let it soften slightly before using. The texture remains creamy and smooth after freezing.

Frequently asked questions
Why does Arby's red ranch sauce have that unique tangy flavor?
The signature tang comes from the buttermilk—it's the secret ingredient that sets this apart from regular ranch. The combination of buttermilk, vinegar, and smoked paprika creates that perfect balance of creamy richness and bright acidity. The buttermilk also adds natural sweetness that rounds out the flavor profile.
Can I make this sauce without buttermilk?
Yes, but the flavor won't be quite the same. For a substitute, mix ½ cup plain yogurt with 1 teaspoon lemon juice to mimic the tang. The texture will be slightly thinner, but it'll still taste delicious. The buttermilk is what gives that signature Arby's kick, though!
How do I fix lumps in my homemade red ranch?
Lumps usually happen when the buttermilk and mayo aren't properly emulsified. Use an immersion blender or transfer to a blender and pulse until smooth. If that doesn't work, strain the sauce through a fine-mesh sieve. For future batches, mix the buttermilk and mayo first until completely smooth before adding other ingredients.
Can I use this sauce for cooking instead of just dipping?
This sauce works perfectly as a marinade for chicken or pork, a sandwich spread, or even a finishing drizzle on loaded baked potatoes. The smoky paprika and garlic powder add great depth to grilled meats. Just remember it's not heat-stable—best used as a finishing touch rather than cooking sauce.
What's the best way to store leftover sauce?
Store in an airtight container in the fridge for up to 5 days. The texture may thicken slightly—just stir and thin with a splash of water or milk if needed. For longer storage, freeze in ice cube trays for single-serving portions. Thaw overnight in the fridge before using.
