Ingredients for arby's super roast beef sauce
Eight pantry staples for that iconic tangy, creamy sauce you crave.
| Ingredient | Amount | Notes |
|---|---|---|
| Ketchup 🍅 | 1 cup | High-quality, no sugar added preferred |
| White Vinegar 💧 | ½ cup | Distilled or apple cider |
| Prepared Horseradish 🌶️ | ¼ cup | Creamy, not coarse |
| Granulated Sugar 🍚 | ¼ cup | Balances sharpness |
| Worcestershire Sauce 🫒 | 1 tbsp | Lea & Perrins preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Heavy Cream 🧈 | ½ cup | Full-fat for creaminess |
| Garlic Powder 🧄 | ½ tsp | For subtle depth |
The ketchup and vinegar are the base, so grab the good stuff—Heinz or Hunt's for ketchup, and distilled vinegar for consistency. Horseradish is non-negotiable for that signature kick; Gourmet Garden creamy horseradish is my go-to, but any prepared version works. Sugar balances the sharpness, so don’t skimp here. Worcestershire sauce adds depth—Lea & Perrins is the classic choice, but any good brand will do. For the creaminess, full-fat heavy cream is key—it’s what makes this sauce velvety instead of watery.
No prepared horseradish? Freshly grated horseradish plus a splash of vinegar works, but it’s spicier and needs more sugar to balance. Short on ketchup? Tomato paste plus a little water gets you close. Vinegar substitute? Lemon juice at half the amount, but it’ll be slightly tangier. The garlic powder can be swapped for 1/4 tsp minced garlic if you’re feeling fancy. For a smoother sauce, strain it after simmering—though the intro says no blender, a quick pulse in a food processor works in a pinch.
This sauce thickens as it cools, so stir in a splash of water if it’s too thick for your liking. Keeps in the fridge for 1 week in an airtight jar, or freeze for 3 months. I double the batch—one for sandwiches, one for fries. The flavor actually improves after a day in the fridge as everything melds together.

Step-by-step instructions for Arby's super roast beef sauce
Here's how to recreate that iconic tangy, creamy sauce with a perfect horseradish kick.
🍳 Step 1: Combine the Base Ingredients
In a medium saucepan, whisk together the 1 cup ketchup, 0.5 cup white vinegar, and 0.25 cup granulated sugar over medium-low heat. Let the mixture simmer gently for 5 minutes until the sugar dissolves completely and the sauce begins to thicken slightly. You'll notice the vinegar's sharp aroma softening as it blends with the ketchup's sweetness.
This initial simmer is crucial—it helps the sugar fully incorporate and removes any raw vinegar bite that might overpower the final sauce. Stir occasionally to prevent sticking, but don't let it boil vigorously or the flavors will become unbalanced.
🍳 Step 2: Add the Horseradish and Seasonings
Reduce the heat to low and stir in the 0.25 cup prepared horseradish, 1 tbsp Worcestershire sauce, 0.5 tsp garlic powder, and 0.5 tsp ground black pepper. Let the sauce simmer for another 3-4 minutes, stirring constantly, until the horseradish is fully incorporated and the mixture becomes slightly thicker. You'll smell that signature horseradish punch developing—this is where the sauce gets its signature kick.
Here's the thing—don't rush this step. The horseradish needs time to meld with the other flavors. If you taste it now and it's too sharp, don't worry—the cream will mellow it out later. The Worcestershire sauce adds that umami depth that makes this sauce so addictive.
🍳 Step 3: Finish with Cream for Richness
Remove the saucepan from heat and let it cool slightly for 2-3 minutes. Then, slowly whisk in the 0.5 cup heavy cream until fully combined. Return the sauce to low heat and let it warm through for 1-2 minutes, stirring constantly. You're looking for a smooth, velvety texture—not too thick, but not runny either.
This is where the magic happens. The cream adds richness that balances the tangy-sweet base, while the residual heat ensures the sauce doesn't curdle. If it starts to look too thick, add 1-2 tablespoons of water to loosen it. The sauce should coat the back of a spoon but still pour smoothly.
⏰ Step 4: Rest and Adjust
Transfer the sauce to a bowl and let it rest at room temperature for 10 minutes. This resting period allows all the flavors to fully meld together. Taste the sauce and adjust the seasoning if needed—you might want to add a pinch more sugar to balance the tang, or a splash more vinegar for extra brightness.
I know it seems counterintuitive to let it sit, but trust me—this makes a MASSIVE difference in the final result. The flavors will come together in a way that's impossible to achieve if you serve it immediately. Once it's perfectly balanced, it's ready to drizzle over your roast beef sandwiches, fries, or even use as a dip!
Pro Tips For Making Arby'S Super Roast Beef Sauce
- STIR CONSTANTLY: The first time I made this, I walked away for "just a minute" while the sauce simmered—big mistake. That horseradish and vinegar combo gets aggressive fast. Keep it moving on medium-low heat, or you’ll end up with a lumpy, bitter mess instead of that smooth, tangy sauce.
- USE FRESH HORSE RADISH: I learned this the hard way—jarred horseradish loses its kick over time. If yours tastes weak, add a splash of lemon juice or a pinch of extra sugar to balance it. Pro tip: Grate a small piece of fresh horseradish (about 1 teaspoon) into the sauce if you’re feeling fancy—it makes a real difference in brightness.
- MEASURE THE VINEGAR FIRST: Too much white vinegar and your sauce turns into a mouth-puckering experiment. Start with 1 tablespoon, taste as you go, and add another only if needed. I’ve ruined batches by eyeballing it—trust me, you’ll regret that extra splash.
- SWEETEN IT GRADUALLY: That sugar isn’t just for flavor—it’s taming the heat. Add it 1 teaspoon at a time while simmering, tasting between additions. If the sauce tastes too sharp, you can’t fix it later. I used to dump it all in at once and end up with a sauce that was either cloyingly sweet or still biting.
Dietary considerations for this dish
Gluten-Free Adaptation
This sauce is naturally gluten-free, but always double-check your ingredients! The Worcestershire sauce is the only potential concern—opt for a certified gluten-free version like Annie's or Bragg. The rest of the ingredients are safe for gluten-free diets. I've made this sauce countless times for gluten-sensitive friends, and they've never noticed the difference. 💛
Dairy-Free Version
For a dairy-free twist, swap the heavy cream with ½ cup coconut cream (the thick part from a can of full-fat coconut milk). The texture will be slightly lighter but still creamy. You might need to add 1 tsp cornstarch mixed with 1 tbsp water to help thicken it properly. The flavor stays true to the original, just with a subtle coconut undertone.
Vegan Option
To make this fully plant-based, replace the heavy cream with ½ cup cashew cream (blend ½ cup soaked cashews with ½ cup water until smooth). For the dairy-free Worcestershire, use 1 tbsp vegan Worcestershire sauce like Primal Kitchen. The sauce will still pack that signature tang and horseradish kick without any animal products. I've tested this version with vegan friends, and they swear it's just as good!
Low-Sugar Adjustments
If you're watching sugar, reduce the granulated sugar to 2 tbsp and add 1 tbsp stevia or monk fruit sweetener instead. The sauce will still taste balanced, though the texture might be slightly thinner. For extra sweetness without sugar, try adding 1 tbsp maple syrup—it adds depth while keeping the sugar content lower. Always taste as you go!
Allergen-Friendly Notes
This sauce is typically safe for most allergies, but here's what to watch: The horseradish might contain trace amounts of mustard (common in prepared versions). For nut allergies, avoid cashew cream substitutions. If you have a vinegar allergy, skip it entirely and use lemon juice instead—just remember it'll be slightly tangier. Always check labels, especially on prepared horseradish and Worcestershire sauce.

Frequently asked questions
Why does the original Arby's sauce taste different from homemade versions?
The restaurant version likely uses proprietary ingredients like a specific blend of spices or a different type of vinegar. Our recipe captures the essence with common pantry staples, but the exact flavor profile might vary slightly. The key is balancing the sweetness, tang, and horseradish kick—this version gets it right!
Can I make this sauce without horseradish?
Yes! For a milder version, replace the ¼ cup horseradish with 1 tbsp prepared mustard plus 1 tsp extra sugar to balance. You'll lose that signature kick, but the sauce will still be tangy and creamy. If you want heat without horseradish, try ½ tsp cayenne pepper instead.
How do I know when the sauce is ready?
The sauce is done when it's smooth, slightly thickened, and coats the back of a spoon after resting. Taste it before serving—it should be tangy-sweet with a subtle horseradish bite. If it's too thin, simmer uncovered for 2-3 more minutes; if too thick, whisk in 1 tbsp water at a time.
Can I make this sauce ahead of time?
This sauce tastes even better after 24 hours, as flavors meld. Store in an airtight jar in the fridge for up to 2 weeks. For longer storage, freeze in 1-tbsp portions. Just give it a quick stir and warm gently before using—no need to reheat.
What can I use this sauce for besides roast beef sandwiches?
This versatile sauce works on burgers, fries, hot dogs, or even grilled chicken. Try it as a dip for veggies or pretzels! For a creative twist, drizzle it over mac and cheese, or use it as a marinade for steak or pork chops***. The tangy-sweet balance pairs surprisingly well with many dishes.
