It's the kind of sauce that transforms ordinary chicken into something truly special.

You'll end up with a sauce that's perfectly balanced—spicy enough to satisfy buffalo lovers, creamy enough to coat every bite, and tangy enough to cut through the richness. The best part? It comes together in just minutes with ingredients you likely already have on hand.

Use it on sliders, as a dipping sauce, or even as a marinade for wings. This is the sauce that will have everyone asking for seconds—no Arby's trip required. Let's get started!

Ingredients for arby's buffalo chicken slider sauce

Pantry staples that deliver that iconic tangy-buttermilk kick—no mystery ingredients, just restaurant-quality flavor.

The buttermilk is non-negotiable here—it's what gives that signature tang. Full-fat makes it richer, so don't skimp. Frank's RedHot is the gold standard for hot sauce, but any bold, vinegar-based sauce works. The butter adds creaminess, but keep it cold when mixing to avoid breaking the sauce. For the vinegar, white works best—it brightens without overpowering. Trader Joe's has a great organic white vinegar if you want to splurge, but the basic stuff from your pantry cabinet does the job too. The garlic and onion powders are just for depth—don't overthink them, but don't skip them either.

No buttermilk? Substitute with 1/2 cup milk plus 1 tbsp lemon juice or vinegar, but let it sit for 10 minutes to thicken. Hot sauce brands vary—Crystal or Louisiana work too, but they're hotter, so start with less. Butter substitute? Vegan butter or coconut oil keeps it dairy-free. The honey is key for balancing heat—agave or maple syrup work in a pinch, but honey has that caramel note that's hard to replicate. If you're watching sugar, cut it to 1 tsp, but the sauce will be sharper. The spices? If you've got fresh garlic and onion, mince 1 clove each and toast them lightly in butter before mixing—the flavor is next-level.

This sauce keeps beautifully. Store in an airtight container in the fridge for up to 1 week, or freeze in ice cube trays for 3 months. It thickens when chilled, so give it a quick whisk before using. Double the batch—you'll want it for everything from sliders to wings. The sauce gets even better the next day as the flavors meld. If it separates, just whisk vigorously or microwave for 10 seconds to re-emulsify. Trust me, you'll make more than you think.

Step-by-step instructions for Arby's-style buffalo chicken sliders sauce

This sauce delivers that signature tangy, creamy heat that clings perfectly to every bite.

Place the 0.5 cup unsalted butter in a medium saucepan over medium-low heat. Let it melt completely, stirring occasionally until it becomes completely smooth and liquid. Once fully melted, remove from heat and let it cool slightly for 2-3 minutes—it should be warm but not hot to the touch.

Add the 1 tablespoon white vinegar and whisk vigorously for 30 seconds. You'll see the mixture curdle slightly as the acid reacts with the fat. This step is crucial—it creates the tangy foundation that balances the heat. Don't skip it, even if it looks weird at first.

In a separate bowl, whisk together the 0.5 cup buttermilk, 0.5 teaspoon garlic powder, 0.5 teaspoon onion powder, 0.25 teaspoon ground black pepper, and 0.5 teaspoon salt until completely smooth. The mixture should look like thick, creamy yogurt with no lumps. I like to use a wire whisk for this to ensure everything is evenly incorporated.

This is where the sauce starts to come together. The spices will dissolve completely in the buttermilk, creating a flavor base that's aromatic and ready to marry with the hot sauce. If you notice any undissolved powder, whisk a bit longer—those spices need to fully integrate for even flavor distribution.

Temper the buttermilk mixture by slowly adding about ¼ cup of the 0.25 cup hot sauce while whisking constantly. This gradual introduction prevents the sauce from curdling too dramatically. Once incorporated, return the saucepan with melted butter to low heat and slowly whisk in the remaining hot sauce, 1 tablespoon at a time.

Here's the thing—adding hot sauce too quickly can make the sauce separate. You want to see it thicken slightly as it comes together. The sauce should be smooth but still pourable. If it starts to look too thin, we'll fix that in the next step. Keep whisking gently to maintain that creamy texture.

Return the sauce to low heat and stir in the 1 tablespoon honey. The honey will help balance the heat from the hot sauce while adding a subtle sweetness that rounds out the flavors. Let the mixture simmer gently for 3-4 minutes, stirring constantly with a wooden spoon.

You'll notice the sauce beginning to thicken as the heat causes the buttermilk proteins to coagulate. If it becomes too thick during this process, add 1-2 tablespoons of water to reach your desired consistency. The sauce should coat the back of a spoon but still be spreadable—not gluey. This is where you achieve that perfect Arby's-style thickness that sticks to sliders without being cloying.

Remove the sauce from heat and let it cool for 10 minutes at room temperature. This cooling period is essential—it allows the flavors to meld completely and the sauce to reach its ideal consistency. I know it's tempting to taste it immediately, but patience here makes all the difference.

Once cooled, give it one final taste and adjust the seasoning if needed. Need more heat? Add another teaspoon of hot sauce. Want more tang? A splash of vinegar. Too thick? Thin with a bit more buttermilk. The sauce should be tangy, creamy, and just spicy enough to make your taste buds tingle. Store in an airtight container in the refrigerator for up to 1 week, or freeze for up to 3 months.

Serving suggestions for leftovers

Slider Pairings

This sauce is designed to elevate Arby's-style sliders, but don't limit it to just chicken. Try it on pulled pork sliders with a touch of BBQ sauce or beef sliders with melted provolone.

For a vegetarian option, use grilled portobello mushrooms or crispy tofu patties. The key is keeping the slider small—about 2-3 ounces of protein—so the sauce can shine without being overwhelmed. 🌟

Dipping Sauce

Transform this into a dipping sauce for Arby's-style chicken tenders or fries. Serve it chilled in a small bowl with a side of celery sticks and carrot sticks for crunch. The tangy, creamy texture pairs perfectly with the crispy exterior of fried foods.

For extra fun, drizzle a little extra sauce on top of the bowl before serving—it makes for a great presentation at parties or game day gatherings.

Wing Sauce

Use this sauce as a dry rub or wet glaze for wings. Toss baked or fried wings in the sauce, then broil for 3-5 minutes to create a sticky, caramelized crust. The heat from the broiler intensifies the buffalo flavors while keeping the wings tender.

Serve with blue cheese dressing and extra celery for a classic wing night experience. Pro tip: Double the recipe to have enough for both dipping and glazing. 🍗

Mac & Cheese Upgrade

Stir ¼ cup of this sauce into creamy mac and cheese just before serving. The tangy, spicy kick cuts through the richness of the cheese, creating a flavor profile that’s both comforting and exciting.

For extra texture, top with crumbled bacon or crispy fried onions. This is a crowd-pleaser for game days or family dinners—just be prepared for seconds (or thirds).

Breakfast Twist

Add a spicy breakfast dimension by drizzling this sauce over scrambled eggs or breakfast burritos. The tangy, creamy heat pairs surprisingly well with the richness of eggs and cheese. For a fun brunch idea, serve it as a dipping sauce for hash browns or biscuits.

It’s a great way to wake up your taste buds on lazy weekends. 💛

Storage Hacks

This sauce keeps well for 1 week in the fridge or 3 months in the freezer. For easy serving, portion it into small jars or squeeze bottles—perfect for on-the-go use.

If the sauce thickens when chilled, simply whisk in 1-2 tablespoons of water or buttermilk to restore its pourable consistency. Freeze extras in ice cube trays for single-use portions, ideal for quick dips or glazes. Label everything clearly so you can grab it fast when inspiration strikes! ❄️
