Ingredients for arby's horsey sauce recipe copycat
Seven simple pantry staples. One unforgettable sauce. Game day just got better.
| Ingredient | Amount | Notes |
|---|---|---|
| Mayonnaise 🥛 | 1 cup | Full-fat preferred for creaminess |
| Prepared Horseradish 🌶️ | ¼ cup | Not horseradish sauce, creamy type |
| White Vinegar 💧 | ½ cup | Distilled or white vinegar |
| Granulated Sugar 🍚 | 1 tbsp | White sugar, no substitutes |
| Worcestershire Sauce 🍶 | 1 tbsp | Lea & Perrins preferred |
| Kosher Salt 🧂 | ½ tsp | Fine grain preferred |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground for best flavor |
| Hot Sauce 🔥 | ½ tsp | Optional, like Crystal or Tabasco |
The mayonnaise and horseradish are non-negotiable—they carry that signature tangy kick. Hellmann's or Duke's mayo works best, nothing light or low-fat. For horseradish, grab the creamy kind (not the sauce with sugar)—it's usually in the condiment aisle near mustard. Trader Joe's has a great one if you want to splurge. The vinegar needs to be white or distilled—apple cider won't give the same bright acidity. I always double-check the sugar too—it's not just for sweetness, it balances the heat. The Worcestershire? Lea & Perrins is the only one that works here—no substitutes.
No prepared horseradish? Fresh horseradish root plus a splash of vinegar gets you close, but it's a pain to grate. Skip the hot sauce if you're sensitive to heat—it's just for extra kick. The sauce thickens as it sits, so if it's too thin right away, let it chill for 30 minutes before serving. Want it sweeter? Add another 0.5 tbsp sugar. Too spicy? A splash of mayo or a pinch more sugar fixes it. This sauce keeps for 1 week in the fridge, but the flavor actually improves after 24 hours—let it mellow.
Store in an airtight container with a lid—plastic wrap pressed right on the surface keeps it from drying out. The flavors meld beautifully overnight, so making it ahead is a must. I usually make a double batch because it disappears fast. Perfect for roast beef sandwiches, fries, or even as a dip for onion rings. Freezes for 3 months if you want to prep for game days. Just give it a stir before using—it might thicken up a bit.

Step-by-step instructions for Arby's Horsey sauce copycat
Here's how to nail that signature tangy, creamy, kick-in-the-pants sauce at home.
Whisk Together the Creamy Base
In a medium bowl, combine the 1 cup mayonnaise and 0.25 cup prepared horseradish. Use a whisk or fork to mix until completely smooth—no streaks of horseradish should remain. This is your creamy foundation, so take your time here. The horseradish needs to fully integrate for that signature sharpness without overpowering the richness of the mayo.
I like to press down on the mixture with the back of my spoon a few times to ensure everything's well blended. This step is all about creating a velvety texture that'll carry the bold flavors we're about to add. If you're using a creamy horseradish (not the sauce), you'll get that authentic Arby's bite without the wateriness that can come from horseradish sauce.
Add the Tangy Components
To the mayo-horseradish mixture, add the 0.5 cup white vinegar, 1 tablespoon granulated sugar, and 1 tablespoon Worcestershire sauce. Whisk vigorously for about 30 seconds until everything is fully incorporated. You'll notice the mixture starts to lighten in color and develop that signature tangy aroma.
The sugar might seem like an odd addition, but it balances the sharpness of the horseradish and vinegar while adding just enough sweetness to round out the flavors. Don't skip this step—it's what makes this sauce sing. The Worcestershire sauce brings depth and that unmistakable umami kick that you find in the original Horsey sauce.
Season with Salt, Pepper, and Heat
Now it's time to season. Add the 0.5 teaspoon kosher salt, 0.25 teaspoon black pepper, and 0.5 teaspoon hot sauce. Mix well until everything is completely combined. Taste the sauce at this point—you should get a good balance of creamy, tangy, and slightly spicy flavors.
Here's where you can adjust to your preference. If it needs more heat, add a tiny bit more hot sauce. If it's too sharp, a pinch more sugar helps. But start with these amounts—they're proven to deliver that perfect copycat balance. The freshly ground black pepper adds a nice finishing touch that elevates the sauce from good to restaurant-quality.
Let It Rest and Develop
Cover the bowl and let the sauce sit at room temperature for at least 15 minutes. This resting period allows all the flavors to meld together and the sauce to reach its full potential. I know it's tempting to dive right in, but trust me—this step makes a huge difference in the final result.
After resting, give the sauce one final taste. The flavors should now be harmonized, with the horseradish heat balanced by the creaminess of the mayo and the tang from the vinegar. If you're making this ahead of time, you can refrigerate it for up to 5 days—it actually tastes better after it's had a chance to chill and the flavors to develop further.
Pro Tips For Making Arby'S Horsey Sauce Recipe Copycat
- STIR GENTLY, NOT VIGOROUSLY: This sauce is delicate—overmixing turns it grainy and breaks down the mayo. Use a rubber spatula and fold ingredients together in slow, deliberate strokes, like you’re folding in a cake batter. I learned this the hard way when mine looked like wet sand after 30 seconds of aggressive whisking.
- USE COLD HORSERADISH: Straight from the fridge, not room temperature. Cold horseradish keeps the heat sharp and prevents the sauce from getting too warm, which makes the mayo separate. I was skeptical until I tried it—now I swear by it, especially if I’m making this ahead of time.
- MEASURE SUGAR BY VOLUME, NOT WEIGHT: For this recipe, a heaping tablespoon of sugar makes a real difference. Spoon it directly into the bowl—don’t scoop with a measuring spoon, or you’ll end up with clumps that won’t dissolve. Trust me, your sauce will taste noticeably smoother if you skip the extra step of weighing it.
- ADD VINEGAR LAST: Start with the mayo, horseradish, and Worcestershire, then let them sit for 30 seconds. Only then add the vinegar and sugar. This lets the flavors meld before the acid cuts in, so you don’t end up with a harsh, tangy punch. I skip this step sometimes, and the sauce always tastes flatter.
Pro cooking tips for great arby's horsey sauce recipe copycat
Horseradish Integration
The key to authentic Horsey Sauce is blending the prepared horseradish completely into the mayonnaise. I use a hand mixer on low speed for 30 seconds to fully emulsify it—this prevents any gritty texture.
If you're using fresh horseradish root, grate it finely and mix it with 1 tablespoon vinegar first to mellow its intensity before combining with mayo. The goal is a smooth, velvety base where you can't taste individual ingredients. 🌶️
Vinegar Balance
White vinegar is non-negotiable here—apple cider vinegar adds fruity notes that throw off the balance. Measure carefully: ½ cup gives that signature tang without overpowering. If your sauce tastes too sharp after mixing, let it rest 10 minutes before tasting again.
The acidity mellows slightly as it sits, but don't add more mayo—it'll dilute the horseradish kick. I've found that distilled white vinegar from Heinz works best for consistency.
Temperature Control
Work in a cool environment—warm ingredients can cause the sauce to separate. If your kitchen is hot, chill the bowl in the fridge for 5 minutes before starting. The mayo should be at room temperature (not cold from the fridge) to blend properly with the horseradish.
I've ruined batches by rushing—take your time mixing to avoid lumps. A silicon spatula helps scrape every bit of sauce from the bowl for maximum flavor.
Adjusting Heat Levels
Too spicy? Add ½ teaspoon sugar or 1 teaspoon mayo to mellow the horseradish. Need more kick? Add ¼ teaspoon hot sauce (like Crystal) or a pinch of cayenne pepper. For a smoky variation, replace ½ teaspoon hot sauce with ¼ teaspoon smoked paprika.
Always adjust gradually—you can't reverse overdoing it. Taste as you go, especially after the 15-minute rest when flavors settle.
Thickening Tricks
If your sauce is too thin after mixing, refrigerate it 30 minutes—it thickens as it cools. For immediate thickening, add 1 teaspoon cornstarch mixed with 1 teaspoon water, then whisk in. Never boil the sauce—heat destroys the mayo's emulsion.
If it separates, whisk vigorously with 1 tablespoon cold water to re-emulsify. The perfect consistency should be spoonable but still spreadable—like the original Horsey Sauce.
Long-Term Storage
Store in an airtight glass container with plastic wrap pressed directly on the surface to prevent drying. The sauce keeps for 1 week in the fridge and 3 months in the freezer, but flavor peaks after 24-48 hours as ingredients meld.
For freezing, portion into ice cube trays—perfect for single-use servings. Thaw overnight in the fridge, then give it a good stir before using. The texture may thicken slightly after freezing, so add 1 teaspoon water if needed. ❄️

Frequently asked questions
Why does Arby's Horsey Sauce have sugar in it?
The sugar balances the sharp horseradish and tangy vinegar, creating that signature sweet-spicy flavor. It rounds out the heat and prevents the sauce from tasting too harsh. Think of it like a secret ingredient that makes the bold flavors harmonize perfectly.
Can I make this sauce without Worcestershire sauce?
You can substitute with 1 tbsp soy sauce or 1 tsp fish sauce for umami depth, but Worcestershire's tangy-savory profile is irreplaceable. The sauce will still work, but it won't have that exact restaurant-quality depth. For best results, track down Lea & Perrins brand.
How do I fix Horsey Sauce that's too thin?
Let it rest 30 minutes in the fridge—it thickens as it cools. For immediate results, mix 1 tsp cornstarch with 1 tsp water, then whisk into the sauce. Never heat it, as that can cause separation. The perfect consistency should be thick enough to hold its shape but still spreadable.
What's the best way to store leftover Horsey Sauce?
Keep it in an airtight glass container with plastic wrap pressed directly on the surface to prevent drying. It stays fresh for 1 week in the fridge and 3 months in the freezer. For freezing, portion into ice cube trays for single-use servings. The flavors actually improve after 24 hours—don't rush to eat it all!
Can I use this sauce on foods other than roast beef?
It's perfect for fries, onion rings, or even as a dip for veggies. The tangy-sweet profile works great with grilled chicken or burgers too. Just avoid pairing it with overly sweet dishes—it's bold enough to stand on its own. Think of it as your new go-to condiment for game day spreads.
