Outback Steak Dip Recipe: Signature Creamy Horseradish Sauce

This horseradish dip recreates the creamy signature sauce from everyone’s favorite steakhouse. I tested it multiple times to get the balance of tangy, spicy, and rich just right.

Simple ingredients come together quickly, but the flavor develops even more after resting for an hour. The prepared horseradish gives it that unmistakable kick, while sour cream keeps it smooth and cool.

Use it for steak dipping, of course, but it also elevates burgers, sandwiches, and even roasted vegetables. The texture stays perfectly thick without separating.

Make a batch ahead and store it in the fridge for up to a week. It tastes even better the next day.

Ingredients for Outback Steak Dip

Nine ingredients for that signature creamy, tangy, spicy steakhouse dip you crave.

The sour cream is non-negotiable here—full-fat for that ultra-creamy texture. I grab mine from Kroger or Publix, but any grocery store brand works fine. For the horseradish, Bubbies or Gold’s are my go-tos (the prepared stuff in the refrigerated section, not shelf-stable). It’s got that fresh kick you need. Mayonnaise? Duke’s or Hellmann’s—no low-fat versions, or the dip won’t set right.

No prepared horseradish? Fresh grated horseradish root works, but it’s intense—use half the amount and mix in a little vinegar to mellow it. Swap mayonnaise for Greek yogurt if you’re in a pinch (thinner texture, but still tasty). Out of Worcestershire? Soy sauce plus a dash of vinegar gets you close. The Dijon can be swapped for yellow mustard, but it’ll be milder.

This keeps for 7-10 days in the fridge, and honestly tastes better after 24 hours once the flavors meld. Store it in an airtight container—glass jars work great. Freezing isn’t ideal (texture separates), but it works for up to 1 month if needed.

Step-by-Step Instructions for Creamy Horseradish Sauce

Here’s the method. Straightforward, tested, works every time.

Step 1: Combine the Creamy Base Ingredients

In a medium bowl, whisk together the 1 cup Sour Cream and 0.5 cup Mayonnaise until completely smooth and uniform in texture. I use full-fat sour cream here—it gives the dip that luxurious, velvety mouthfeel you expect from a restaurant-quality sauce.

The mixture should look pale and slightly thick. If you notice any separation, keep whisking until it comes together. This base provides the perfect canvas for all the bold flavors we’re about to add.

Step 2: Incorporate the Flavorful Additions

Add the 0.25 cup Prepared Horseradish, 1 tbsp Worcestershire Sauce, and 1 tbsp Dijon Mustard to the bowl. The horseradish is the star here—it delivers that signature kick that makes this dip so addictive. Use prepared horseradish for convenience and consistent texture.

Whisk vigorously for 30-45 seconds until all ingredients are fully integrated. You’ll see the color lighten slightly as the horseradish distributes evenly. The Worcestershire adds depth, while the Dijon mustard brings a subtle tang that balances the heat.

Step 3: Season and Brighten the Mixture

Sprinkle in the 0.5 tsp Garlic Powder, 0.5 tsp Onion Powder, 0.25 tsp Salt, and 0.25 tsp Black Pepper. These dry seasonings enhance the savory notes without overpowering the horseradish. I always use freshly ground black pepper when possible—it makes a noticeable difference.

Finally, add the 1 tsp Lemon Juice and whisk once more. The acidity cuts through the richness of the sour cream and mayonnaise, brightening the entire mixture. Freshly squeezed lemon juice works best here for the cleanest, most vibrant flavor.

Step 4: Chill and Let Flavors Meld

Cover the bowl with plastic wrap and refrigerate for at least 1 hour (I prefer 2 hours for maximum flavor development). This resting time allows all the ingredients to harmonize, with the horseradish mellowing slightly and the spices fully infusing the creamy base.

While you can serve it immediately, the flavors deepen significantly after chilling. The texture will also thicken slightly, making it perfect for dipping. Give it a quick stir before serving to redistribute any separated elements.

This dip keeps beautifully in the refrigerator for up to 5 days, so you can make it ahead for gatherings. The horseradish kick may intensify slightly over time, so taste and adjust seasoning if needed before serving.

Classic Pairings

This dip was made for medium-rare steak, especially ribeye or sirloin. The creamy horseradish cuts through the beef’s richness perfectly. I always slice my steak thin for maximum dip coverage. 🔥

Burger Enhancement

Spread a generous 2 tbsp on your next cheeseburger—it adds a gourmet touch that elevates even simple ground beef. Works particularly well with blue cheese crumbles on top.

Sandwich Boost

Try it on roast beef or French dip sandwiches. The horseradish complements the beef while the creaminess balances the bread. I love it with ciabatta rolls from my local Italian deli.

Veggie Dip

Don’t limit yourself to meat—this makes an incredible dip for raw or roasted vegetables. Carrot sticks, celery, and bell pepper strips become restaurant-worthy appetizers with this sauce.

Potato Partner

Drizzle over baked potatoes or use as a dip for fries and tater tots. The cool creaminess contrasts beautifully with hot, crispy potatoes. I’ve tested this multiple times—it’s a crowd-pleaser every time.

Seafood Surprise

Surprisingly great with cold shrimp or crab cakes. The tangy horseradish brightens seafood’s natural sweetness. I discovered this combo accidentally at a Boston summer party—now it’s a staple.
