Ingredients for arby's roast beef sauce
Nine ingredients blend to recreate Arby's iconic smoky, tangy sauce at home.
| Ingredient | Amount | Notes |
|---|---|---|
| Ketchup 🍅 | 1 cup | Sweet, quality brand preferred |
| Horseradish 🌶️ | ¼ cup | Freshly grated, strong variety |
| Worcestershire Sauce 🍶 | 2 tbsp | Lea & Perrins preferred |
| White Vinegar 💧 | 1 tbsp | For tangy brightness |
| Smoked Paprika 🌶️ | 1 tsp | For signature smoky flavor |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Onion Powder 🧅 | ½ tsp | For subtle depth |
| Ground Black Pepper 🌶️ | ¼ tsp | Freshly cracked preferred |
| Granulated Sugar 🍚 | 1 tbsp | Balances tangy flavors |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
The ketchup and horseradish are non-negotiable—they create that signature sweet-tangy balance. Heinz ketchup works best for consistency, but any sweet brand will do. For horseradish, grab the fresh root and grate it yourself—pre-grated loses its kick fast. Worcestershire sauce adds depth, so don't skimp. Lea & Perrins is the gold standard, but any good brand works. The smoked paprika? That's what gives it that unmistakable Arby's smokiness—store it in a cool, dark place to keep it potent. I always double-check my spices are fresh, especially the paprika and garlic powder, since they're doing most of the flavor work here.
No Worcestershire? Soy sauce plus a pinch of sugar gets you close, though it won't be identical. Short on fresh horseradish? Prepared horseradish at half the amount works in a pinch, but you'll lose some intensity. The vinegar and sugar are easy to adjust—add more vinegar for tang, more sugar for sweetness. Want to make it even closer to Arby's? Add 1/4 tsp of mustard powder for that subtle tang. The powders can be swapped out too—garlic salt instead of garlic powder if you're in a rush, though it'll be slightly saltier. Store-bought ketchup with onion bits? Strain it first for a smoother sauce.
This sauce keeps beautifully—2 weeks in the fridge sealed in a jar. I like to make a big batch and portion it into small containers for easy dipping. The flavors actually get better after a day or two as everything melds together. For meal prep, this is a game-changer—freeze portions in ice cube trays for single-use servings. Just thaw and stir. If it thickens too much, a splash of water or vinegar brings it back to perfect consistency. The secret to Arby's sauce is patience—let it sit before tasting, and trust the process.

Step-by-step instructions for Arby's roast beef sauce
Here's how to recreate that iconic smoky, tangy sauce you know and love.
Whisk Together the Base Ingredients
In a medium bowl, combine the 1 cup ketchup, 0.25 cup freshly grated horseradish, and 2 tablespoons Worcestershire sauce. I like to use a whisk for this step—it helps break up any horseradish chunks and ensures everything blends smoothly. The horseradish will add that signature kick that makes this sauce stand out from regular ketchup.
Next, stir in the 1 tablespoon white vinegar and 1 tablespoon granulated sugar. The vinegar brightens the flavors while the sugar balances the tanginess. Mix well until the sugar dissolves completely. If you're using a quality ketchup, you'll already notice the rich, slightly sweet base developing—this is your foundation.
Add the Dry Seasonings
To the wet mixture, sprinkle in the 1 teaspoon smoked paprika, 1 teaspoon garlic powder, 0.5 teaspoon onion powder, 0.25 teaspoon ground black pepper, and 0.5 teaspoon salt. I always measure these carefully—too much paprika can overpower, while too little won't give that authentic Arby's smokiness.
Use a fork or small whisk to fold these dry ingredients into the wet mixture until fully combined. You're looking for a smooth, well-incorporated sauce with no visible streaks of powder. The smoked paprika is what gives this sauce its signature depth, so don't skip this step—it's what makes it taste like the real deal.
Taste and Adjust the Balance
Give the sauce a taste right now—this is where you'll decide if any adjustments are needed. The sauce should be tangy from the vinegar and horseradish, with a touch of sweetness from the sugar and ketchup. If it needs more heat, add a pinch more horseradish. If it's too sharp, a tiny bit more sugar can help balance it.
I usually find this recipe hits the mark perfectly, but everyone's taste buds are different. The key is to build the sauce gradually—start with the full recipe, taste, and adjust as needed. Remember, you can always add more horseradish or sugar later if needed, but you can't take it out once it's in.
Let It Rest and Develop
Transfer the sauce to a clean jar or airtight container. Let it sit at room temperature for at least 15 minutes before using. This resting time allows all the flavors to meld together and the horseradish to mellow slightly—it's what transforms this from a simple mix into that authentic Arby's taste.
The sauce will keep in the refrigerator for up to 2 weeks, though I usually use it up much faster. The flavors actually improve slightly over time as everything continues to blend. When you're ready to use it, give it a good stir—especially if you've stored it for a while—as the horseradish tends to settle at the bottom.
Pro Tips For Making Arby'S Roast Beef Sauce
- STIR CONSTANTLY FOR 5 MINUTES: I used to walk away after mixing, but the horseradish and Worcestershire need constant stirring to fully integrate—otherwise, you’ll end up with clumpy bits that ruin the smoothness. Set a timer and don’t look away.
- USE FRESH HORSERADISH (OR PREPARE IT RIGHT): Store-bought prepared horseradish loses punch fast. If using powder, mix it with just a splash of vinegar first—it dissolves better and won’t overpower the sauce. (Yes, even if you’re impatient like me.)
- DILUTE THE VINEGAR FIRST: Pour the white vinegar into the ketchup before adding Worcestershire—this prevents a harsh, unbalanced tang. I learned this the hard way after a batch tasted like a pickle bomb.
- SMOKED PAPRIKA LAST, THEN REST: Sprinkle the smoked paprika on top after everything else is mixed, then let the sauce sit for 10 minutes. This lets the spices bloom without burning, and the flavors meld better. (Your future self will notice the difference.)
Storing and reheating this dish
Fridge Storage Tips
Store your homemade Arby's roast beef sauce in an airtight glass jar—I use Ball canning jars for their tight seals. Keep it refrigerated at 40°F or below for up to 2 weeks.
The glass preserves flavor better than plastic, and the jars stack neatly in your fridge. Always leave ½ inch of headspace to prevent spills when the horseradish settles. 🧂
Freezing for Later
For longer storage, freeze the sauce in ice cube trays—perfect for single-use portions. Once frozen, transfer cubes to a freezer bag with all air removed to prevent freezer burn. Thaw overnight in the fridge before using.
If the sauce thickens after freezing, stir in 1 teaspoon water or vinegar to restore consistency. Label bags with the date—it keeps quality for 3 months.
Reheating Safely
Reheat sauce gently on the stovetop over low heat for 2-3 minutes, stirring constantly. Microwave in 20-second bursts on 50% power, stirring between each, until warmed through.
Never reheat above 165°F—the horseradish can become bitter if overcooked. For dipping, I like to serve it at room temperature for the best flavor balance. 🔥
Reviving Thickened Sauce
If your sauce thickens during storage, thin it with 1 teaspoon water or vinegar at a time. For a smoother texture, strain through a fine-mesh sieve to remove any settled horseradish bits.
If it separates, whisk vigorously—this sauce is forgiving! The key is patience; let it sit for 5 minutes after thinning before tasting again. 💫
Portioning for Meal Prep
Divide sauce into small jars (like 4-ounce portions) for easy grab-and-go dipping. Store in the fridge and use within 7 days for peak freshness. For sandwich prep, keep a jar in your fridge and dip slices directly—no mess, no fuss.
The horseradish flavor mellows slightly over time, so fresh batches taste spicier. 🍽️

Frequently asked questions
Can I make this sauce without fresh horseradish?
Yes, but it won't be as potent! Use 2 tablespoons of prepared horseradish instead of ¼ cup fresh. The flavor will be milder, but you can add a pinch more smoked paprika (¼ teaspoon extra) to compensate. For a smoother texture, strain the prepared horseradish through a fine-mesh sieve first.
How can I make this sauce spicier?
Add ½ teaspoon cayenne pepper or 1 teaspoon hot sauce (like Tabasco) to the finished sauce. For a smoky kick, increase the smoked paprika to 1.5 teaspoons. Always taste first—horseradish heat builds over time, so start conservative. Let it sit for 10 minutes before adjusting again.
What's the best way to use this sauce?
This sauce is perfect for dipping roast beef sandwiches, but it also works as a marinade for meats or a glaze for baked potatoes. Try brushing it on grilled chicken or mixing it into mashed potatoes for extra flavor. For best results, serve it at room temperature—it's less sharp when cold.
Why does my sauce look too thin?
If your sauce is too runny, let it sit uncovered in the fridge for 1-2 hours to thicken naturally. For immediate results, mix 1 teaspoon cornstarch with 1 tablespoon cold water, then stir into the sauce and simmer for 2 minutes until thickened. Avoid overcooking—just enough to coat the back of a spoon.
Can I use this sauce on vegetarian dishes?
The smoky, tangy flavors work great on portobello mushrooms, grilled tofu, or even as a dipping sauce for veggie burgers. For a vegetarian version, swap the Worcestershire sauce for 2 tablespoons soy sauce plus ½ teaspoon sugar. The horseradish adds a nice kick that complements plant-based proteins perfectly.
