Ingredients for arby's roast beef sandwich sauce
Nine essential ingredients blend sharpness, creaminess, and tang for Arby's iconic signature sauce.
| Ingredient | Amount | Notes |
|---|---|---|
| Prepared Horseradish 🌶️ | ½ cup | High-quality, freshly grated preferred |
| Mayonnaise 🥫 | 1 cup | High-fat, full-bodied preferred |
| Garlic Cloves 🧄 | 4 cloves | Fresh, minced for optimal flavor |
| White Vinegar 💧 | 2 tbsp | Distilled for tangy brightness |
| Worcestershire Sauce 🥫 | 1 tbsp | High-quality, anchovy-free version |
| Kosher Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | ¼ tsp | Freshly cracked for maximum aroma |
| Granulated Sugar 🍚 | 1 tsp | Balances sharpness with subtle sweetness |
| Heavy Whipping Cream 🥛 | ¼ cup | Full-fat for optimal texture |
| Yellow Mustard 🍯 | 1 tbsp | Smooth, not chunky |
The prepared horseradish is non-negotiable—Gourmet Garden or Horn's brands deliver the most consistent heat without bitterness. Freshly minced garlic elevates the sauce dramatically, though jarred minced garlic works in a pinch. For Worcestershire, Lea & Perrins is the gold standard, but any high-quality brand will suffice. The mayonnaise should be full-fat; Hellmann's or Duke's provide the ideal creamy base without overpowering the other flavors. Purchase horseradish and Worcestershire from well-stocked grocery stores like Whole Foods or Kroger for optimal freshness and quality.
No prepared horseradish? Fresh horseradish root grated and mixed with a pinch of sugar mimics the texture and sharpness. Substitute jarred minced garlic with one extra clove of fresh garlic for deeper flavor. Out of Worcestershire? A blend of soy sauce and a dash of balsamic vinegar approximates its umami depth. For a lighter version, reduce the heavy cream to 2 tablespoons and add an extra tablespoon of mayonnaise. The yellow mustard should be smooth—chunky varieties can disrupt the sauce's silky texture. Adjust the sugar to taste if your horseradish is particularly pungent.
This sauce reaches peak flavor after 30 minutes of resting, allowing the ingredients to meld. Store in an airtight container in the refrigerator for up to two weeks, though it typically lasts 10-14 days without losing potency. For long-term storage, freeze in ice cube trays, then transfer to a sealed bag for up to 3 months. The sauce thickens slightly when refrigerated—stir before using. Thaw frozen portions gradually in the fridge to preserve texture.

Step-by-step instructions for Arby's-inspired roast beef sauce
This sauce delivers the signature tangy, creamy balance that makes Arby's sandwiches legendary.
Mince the Garlic Cloves
Peel the 4 cloves garlic cloves and finely mince them using a sharp chef's knife or microplane. You want a paste-like consistency—this ensures even distribution and maximum flavor infusion. I press down firmly with the flat of my knife to create a smooth texture before adding it to the mixture.
Fresh garlic makes all the difference here. Pre-minced garlic often contains anti-caking agents that mute flavor. The minced garlic will release its aromatic oils immediately when combined with the vinegar, creating that signature sharpness that cuts through the richness of the mayonnaise.
Whisk Together the Base Ingredients
In a medium bowl, combine the 1 cup mayonnaise, 0.5 cup prepared horseradish, and 1 tbsp yellow mustard. Use a whisk to blend thoroughly for about 30 seconds until smooth. This creates the creamy foundation that will carry all the other flavors.
The horseradish adds that signature kick, while the mustard provides depth. Don't skip this blending step—uneven mixing can create pockets of raw horseradish that will make each bite too sharp. The mayonnaise should now be uniformly colored with no visible streaks of horseradish.
Incorporate the Acidic Components
Add the 2 tbsp white vinegar, 1 tbsp Worcestershire sauce, 0.5 tsp kosher salt, and 0.25 tsp freshly ground black pepper to the bowl. Whisk continuously for 1 minute until all ingredients are fully incorporated. The mixture should now have a slightly thickened consistency with a balanced tang.
This is where the sauce's signature flavor profile develops. The vinegar brightens the richness of the mayonnaise, while the Worcestershire sauce adds umami depth. The salt and pepper work together to enhance all the other flavors without overpowering them. Taste at this stage—you should detect all components working together.
Add Sweetness and Creaminess
Stir in the 1 tsp granulated sugar and 0.25 cup heavy whipping cream using a rubber spatula. Mix gently until fully combined—this prevents over-aeration that could make the sauce too light. The sugar balances the sharpness of the horseradish and vinegar, while the cream adds luxurious body.
Here's the thing—this step requires patience. Stirring too vigorously can incorporate air, which would make the sauce separate later. Instead, use a folding motion to gently incorporate the cream until you achieve a smooth, velvety texture that coats the back of a spoon.
Rest and Adjust the Sauce
Cover the bowl with plastic wrap and refrigerate for at least 30 minutes before serving. This resting period allows all the flavors to meld together fully. After resting, taste again and adjust seasoning if needed—you might want to add a pinch more salt or a splash of vinegar to perfect the balance.
The sauce should now have that perfect harmony of creamy, tangy, and slightly spicy notes that makes Arby's sauce so distinctive. For best results, serve immediately on roast beef sandwiches or store in an airtight container in the refrigerator for up to 5 days. The flavors will continue to develop over time, becoming even more complex.
Pro Tips For Making Arby'S Roast Beef Sandwich Sauce
- Mince the Garlic Fine: I learned this the hard way—lumpy garlic in the sauce ruins the texture. Use a microplane or the flat side of your knife to grind the cloves into a paste before adding them. No food processor? Smash them with the side of your knife first, then chop aggressively.
- Mix in Stages: Don’t dump everything in at once—start with mayo and horseradish, then whisk in the vinegar and Worcestershire. The acidity can break down the mayo if you combine it too early. Taste as you go; you can always add more Worcestershire, but you can’t un-vinegar it.
- Skip the Raw Horseradish: Store-bought prepared horseradish is fine, but if you’re using fresh, grate it last and use just 1 teaspoon. Fresh horseradish is way stronger and can overpower the sauce. Save the extra for deviled eggs or hot dogs where it belongs.
- Chill Before Serving: This sauce tastes flat if it’s warm. Whisk everything together, then refrigerate for at least 30 minutes before using. The flavors meld, and the mayo firms up—no more greasy mess on your sandwich. (Yes, even if you’re impatient like me.)
Flavor customization for this dish
Spice Level Control
Adjust the heat by modifying the prepared horseradish amount. For mild heat, reduce to ¼ cup—this keeps the sauce creamy with just a hint of kick. For medium heat (classic Arby's style), use the full ½ cup.
If you love spice, add 1 extra tablespoon of prepared horseradish or a pinch of cayenne pepper for extra fire. I’ve found Gourmet Garden brand delivers the most consistent heat without bitterness. 🌶️
Tangy Variations
Want more tang? Swap the white vinegar for apple cider vinegar (add 1 extra tablespoon)—it brings fruity brightness that pairs beautifully with roast beef. For a deeper umami punch, add ½ teaspoon of Dijon mustard alongside the yellow mustard.
If you prefer a smoother finish, reduce the vinegar to 1 tablespoon and add ½ teaspoon of honey to balance sharpness. The key is tasting as you go!
Creamy Alternatives
For a lighter version, replace the heavy whipping cream with ½ cup Greek yogurt (full-fat for best texture). This cuts calories while keeping the sauce velvety. If you’re avoiding dairy, use ¼ cup coconut cream—it’s neutral but adds richness.
For extra decadence, stir in 1 tablespoon of sour cream at the end. Just remember: dairy-free swaps may alter the sauce’s clinginess on sandwiches.
Sweet-Savory Balance
Adjust the granulated sugar to taste—some horseradish brands are sharper than others. For a caramelized depth, replace the sugar with 1 teaspoon of maple syrup or ½ teaspoon of brown sugar. If your sauce tastes too sweet, add ½ teaspoon of lemon juice to cut through it.
The goal is a subtle sweetness that rounds out the heat without overpowering the roast beef’s savory notes.
Umami Boosters
Elevate the sauce’s depth with umami-rich additions. Stir in ½ teaspoon of fish sauce (like Red Boat) for an authentic Asian-inspired twist. For a smoky touch, add ¼ teaspoon of smoked paprika or 1 teaspoon of soy sauce.
If you love garlic, add an extra clove (now 5 total) for a more intense aroma. These tweaks work especially well for roast beef sliders or charcuterie boards.

Frequently asked questions
Can I make this sauce without horseradish?
Yes, but it won't taste exactly like Arby's! For a milder version, replace the horseradish with 1 tablespoon of prepared mustard plus ½ teaspoon of cayenne pepper. For a sweeter alternative, use ¼ cup of finely grated apple (peeled) mixed with ½ teaspoon of lemon juice to mimic some of the sharpness. The sauce will still be creamy but lose that signature kick.
How long will this sauce keep in the fridge?
The sauce stays fresh for up to 2 weeks when stored in an airtight container. For longer storage, freeze in ice cube trays—thaw overnight in the fridge before using. The texture may thicken slightly when refrigerated, so give it a good stir before serving. If you notice any separation, whisk vigorously to recombine before using.
Can I use this sauce on other foods besides roast beef?
This versatile sauce works beautifully on burgers, sliders, fries, or even as a dip for veggie sticks. Try drizzling it over grilled chicken wings or mixing it into deviled eggs for a tangy twist. The creamy texture and balanced flavors make it perfect for enhancing any protein-rich dish.
Why does my sauce taste too sharp?
Too much horseradish or vinegar can make the sauce overwhelming. Balance the sharpness by adding ½ teaspoon of sugar or 1 teaspoon of honey to round out the flavors. If it's still too strong, stir in 1 extra tablespoon of mayonnaise to dilute the intensity. Taste as you go—small adjustments make all the difference!
Can I make this sauce in advance for a party?
Yes! This sauce actually tastes better when made ahead. Prepare it 1-2 days in advance to let the flavors fully develop. Store in an airtight container in the fridge, and give it a good stir before serving. The longer it rests, the more complex and balanced the flavors become—perfect for feeding a crowd.
