Ingredients for arby's super roast beef sauce
Nine simple ingredients unlock that iconic Arby's sauce tangy-sweet magic you crave.
| Ingredient | Amount | Notes |
|---|---|---|
| Ketchup 🍅 | ¾ cup | Heinz or Hunt's preferred |
| Prepared Horseradish 🧅 | ¼ cup | Crema-style for creaminess |
| Apple Cider Vinegar 💧 | ¼ cup | Bragg or organic preferred |
| Light Brown Sugar 🍚 | ¼ cup | Packed, not loosely packed |
| Granulated Garlic 🧄 | 1 tsp | For subtle garlic depth |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Ground Mustard 🌿 | ½ tsp | Dijon-style for tang |
| Onion Powder 🧅 | ¼ tsp | For subtle sweetness |
| Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Water 💧 | ¼ cup | For thinning consistency |
The ketchup is non-negotiable—Heinz or Hunt's gives you that classic tang. Prepared horseradish is key here, but crema-style (like Gourmet Garden) adds creaminess that store-bought versions miss. Apple cider vinegar is sharper than white vinegar, which is crucial for that signature bite. For the brown sugar, light variety dissolves better than dark—no gritty surprises. I always grab mine from Trader Joe's bulk bins since it's cheaper and lasts forever. The spices? Freshly ground pepper and Dijon mustard make all the difference—pre-ground spices just don't cut it.
No prepared horseradish? Fresh grated horseradish plus 1 tsp lemon juice works in a pinch, but you'll lose some of that signature creaminess. Vinegar substitute? White vinegar at half the amount gets you close, but you'll miss that apple cider depth. The brown sugar can be swapped for white sugar plus 1/4 tsp cinnamon if you're out, though it'll taste slightly different. For the garlic and onion powders, garlic salt can't replace them—those separate spices are essential. The water is for thinning—if your sauce is too thick, add more 1 tbsp at a time until it reaches that perfect dipping consistency.
This sauce thickens as it sits, so shake it well before using. Keeps in the fridge for 2 weeks in an airtight container, though I always make extra because it disappears fast. Freezes beautifully for 3 months—just thaw in the fridge overnight. The flavors actually improve after a day or two as everything melds together. For best results, let it sit at room temperature for 10 minutes before serving—trust me, it's worth the wait.

Step-by-step instructions for Arby's super roast beef sauce
Here's how to recreate that iconic tangy-sweet sauce with restaurant-quality precision.
Combine the Base Ingredients
In a medium saucepan, add the 0.75 cup ketchup, 0.25 cup prepared horseradish, 0.25 cup apple cider vinegar, and 0.25 cup light brown sugar. Stir these ingredients together over medium-low heat until the sugar begins to dissolve completely—this should take about 3-4 minutes. The mixture will start to bubble gently, and the sugar will create a subtle caramelized depth that's essential for that Arby's signature flavor.
I like to use a wooden spoon for stirring here because it helps scrape up any sugar crystals clinging to the bottom of the pan. This ensures every spoonful of sauce gets that perfect sweet-tangy balance. Keep the heat at medium-low—too high and you'll burn the horseradish before the sugar dissolves properly.
Add Spices and Simmer
Once the sugar is fully dissolved, reduce the heat to low and add the 1 tsp granulated garlic, 0.5 tsp ground black pepper, 0.5 tsp ground mustard, 0.25 tsp onion powder, and 1 tsp salt. Stir everything together for 1-2 minutes until the spices are fully incorporated and the mixture is smooth. The sauce should begin to thicken slightly as the spices release their aromas.
Here's the thing—don't walk away. You want the spices to bloom gently without burning. The mustard and horseradish will give you that signature tang, while the garlic and onion powder add subtle depth. If the sauce starts to smell too sharp, just add a splash of the 0.25 cup water later to balance it out.
Thin and Finish the Sauce
After the spices have had time to meld, increase the heat to medium and add the 0.25 cup water all at once. Stir continuously for 2-3 minutes until the sauce reaches a smooth, pourable consistency. You're looking for a sauce that coats the back of a spoon but isn't too thin—it should be thick enough to cling to roast beef but still flow easily.
Taste the sauce and adjust the seasoning if needed. If it's too sharp, add a pinch more sugar. If it's too sweet, a splash more vinegar or a tiny bit of salt can balance it out. The sauce should have a perfect harmony of tangy, sweet, and slightly spicy notes—just like the original.
Cool and Store
Remove the saucepan from heat and let the sauce cool to room temperature. This step is crucial—cooling the sauce allows the flavors to fully meld and prevents the horseradish from becoming too harsh when served cold. Once cooled, transfer the sauce to an airtight container and refrigerate for at least 1 hour before using. The flavors will deepen and come together beautifully during this time.
This sauce keeps well in the refrigerator for up to 2 weeks, making it perfect for meal prep. When you're ready to serve, give it a quick stir—it might thicken slightly as it cools, so you can thin it with a splash of water if needed. Now you're ready to drizzle it over your homemade roast beef sandwiches like a true Arby's fan!
Pro Tips For Making Arby'S Super Roast Beef Sauce
- STIR CONSTANTLY LOW HEAT: The sauce will burn faster than you think—keep it on a simmer, not a boil, and stir every 30 seconds. I learned this the hard way after walking away for "just a minute" and coming back to a charred mess.
- GRATE THE HORSERADISH FRESH: Store-bought prepared horseradish loses its kick over time. If you’re using jarred, add a pinch of extra garlic powder to compensate, but fresh grated is the only way to get that sharp, clean heat Arby’s nails.
- MEASURE THE VINEGAR FIRST: Add the apple cider vinegar last and let it sit for 30 seconds before tasting. It needs time to cut through the sweetness—rushing this step means you’ll either overcompensate with sugar or miss the balance entirely.
- SWAP GRANULATED GARLIC FOR MINCED: Granulated garlic works, but minced cloves toasted in a dry pan for 30 seconds add depth. The nutty aroma makes the sauce taste like it’s been simmering for hours, not minutes. (Yes, even if you’re impatient like me.)
Storing and reheating your leftovers
Fridge Storage Tips
Store your homemade sauce in an airtight container—I use glass mason jars with tight-sealing lids to preserve freshness. The sauce will last up to 2 weeks in the fridge, but I always make extra because it disappears fast!
The flavors actually improve after 24 hours as the ingredients meld together beautifully. Just give it a quick stir before using, as it may thicken slightly over time. 💪
Freezer Prep
For long-term storage, portion the sauce into freezer-safe containers or silicone ice cube trays (perfect for single-use portions). Freeze for up to 3 months—the sauce maintains its bold flavors when thawed properly.
To use, transfer the frozen sauce to the fridge overnight for a slow thaw, or microwave for 30 seconds on low power, stirring halfway. Never microwave it fully, as the horseradish can become harsh when overheated. ❄️
Reheating Methods
For stovetop reheating, pour the sauce into a small saucepan and warm over low heat for 2-3 minutes, stirring constantly. Add 1-2 teaspoons of water if it thickens too much.
Microwave reheating? Use 30-second intervals on low power, stirring between each, until warmed through. Avoid high heat—it can make the horseradish overpower the sauce's delicate balance. 🔥
Thinning Tricks
If your sauce thickens after refrigeration, thin it with water (not milk or vinegar) to restore its perfect dipping consistency. Start with 1 teaspoon at a time, stirring well after each addition.
Pro tip: Store the sauce in a wide-mouth jar—it’s easier to stir and pour when thickened. The sauce should coat the back of a spoon but still flow smoothly. 💡
Flavor Boost After Storage
After refrigeration, the sauce’s flavors deepen—especially the horseradish and vinegar notes. Let it sit at room temperature for 10 minutes before serving to balance the tang. If the sauce tastes too sharp after storage, add a pinch of brown sugar or a splash of apple cider vinegar to rebalance.
The key is patience—rushing reheating can dull the sauce’s signature kick. ✨

Frequently asked questions
Can I make this sauce without prepared horseradish?
Yes, but the flavor will be slightly different. Use 2 tablespoons fresh horseradish root (grated) plus 1 teaspoon lemon juice to replace the 0.25 cup prepared horseradish. The fresh version has a sharper bite, so you may want to reduce the vinegar by 1 tablespoon to balance the flavors.
How spicy is this sauce compared to Arby's original?
The recipe closely mimics Arby's signature tangy-sweet profile with a mild horseradish kick—not overly spicy like hot sauce. The prepared horseradish and mustard provide subtle heat, while the brown sugar and ketchup balance it perfectly. For extra spice, add ¼ teaspoon cayenne pepper, but start small!
Can I use this sauce as a marinade for roast beef?
This sauce makes an excellent marinade for roast beef. Use ½ cup sauce per pound of meat and marinate for 4-6 hours (or overnight for deeper flavor). The horseradish and vinegar tenderize the meat while infusing it with that iconic Arby's taste. Just pat the meat dry before cooking to ensure a good sear.
Why did my sauce turn out too thin or too thick?
Sauce consistency depends on cooling time. If it's too thin after refrigeration, reduce the water by 1 tablespoon next time. If too thick, add water 1 teaspoon at a time while reheating. The sauce naturally thickens as it cools, so always adjust fresh off the heat. For perfect thickness, let it sit at room temperature for 10 minutes before tasting.
What's the best way to serve this sauce?
Drizzle it over roast beef sandwiches, use as a dip for fries or onion rings, or serve as a glaze for grilled meats. For extra authenticity, pair it with Arby's-style toasted sesame seed buns or a crisp lettuce wrap. The sauce also works as a tangy dressing for roasted potatoes or coleslaw.
