There’s a moment in a great steakhouse meal when the condiments arrive, and among them, that cool, creamy, sinus-clearing horseradish sauce is the undisputed star. It’s the perfect foil to rich, savory beef—a tangy, spicy, luxurious bite that cuts through the fat and elevates every mouthful. For years, Ruth’s Chris Steak House has served one of the most iconic versions.
Today, I’m sharing my professionally tested, foolproof recipe to bring that signature steakhouse magic right to your kitchen table. With just a handful of ingredients and five minutes of hands-on time, you can create a creamy, perfectly balanced horseradish sauce that will make any home-cooked steak feel like a celebratory dinner out.
This recipe demystifies a restaurant favorite and puts an incredibly versatile condiment in your culinary toolkit.

Ingredients You’ll Need
- Let’s gather our ingredients. The magic of this sauce lies in the balance of rich dairy, pungent horseradish, and subtle acidic notes. Quality matters here, as each component plays a starring role.
- Sour Cream: This is the creamy, tangy base. I insist on full-fat sour cream for its luxurious texture and richer flavor. Low-fat versions can be thin and sometimes have a slightly sour tang that can throw off the balance.
- Prepared Horseradish: This is the heart of the sauce. You’ll find it in the refrigerated section, usually near the pickles or cheeses. Crucial Tip: Before measuring, drain it in a fine-mesh strainer and press out the excess liquid. This prevents a watery sauce. For a more potent, fresh kick, you can substitute with freshly grated horseradish root.
- Heavy Cream: A little cream lightens the density of the sour cream, giving the sauce a smoother, more luxurious mouthfeel and a beautiful, dippable consistency.
- Dijon Mustard: Don’t skip this! It’s not for mustard flavor, but for depth. The mustard acts as an emulsifier and adds a complex, background tang that rounds out the sharpness of the horseradish.
- White Wine Vinegar: A small amount of acid is non-negotiable. It brightens the entire sauce, lifting the rich dairy and making the horseradish flavor “pop.” Fresh lemon juice works beautifully as a substitute.
- Kosher Salt & Black Pepper: Seasoning is key. Kosher salt dissolves easily and seasons evenly. Freshly cracked black pepper adds a gentle warmth. For a pristine white sauce, use white pepper.
- Fresh Chives (Optional): A garnish of finely chopped chives adds a mild onion flavor and a lovely pop of green, making your presentation look professional.

Kitchen Equipment Needed
You likely have everything you need already. This recipe requires minimal equipment, which is part of its charm.
- Medium Mixing Bowl: A bowl with a bit of room for whisking is perfect.
- Whisk or Fork: A whisk incorporates everything smoothly, but a sturdy fork works just fine.
- Measuring Cups and Spoons: For accuracy, especially with the horseradish and acid.
- Fine Mesh Strainer: Essential for draining the prepared horseradish. If you don’t have one, you can spoon the horseradish into a paper towel and gently squeeze out the liquid.
- Airtight Container: For storing any leftovers in the refrigerator.
How to Make Ruth’s Chris Horseradish Sauce Recipe
Step 1: Combine the Base
In a medium mixing bowl, combine the sour cream and your well-drained prepared horseradish. Use a whisk or a fork to stir them together until just combined. Tip from me: Avoid over-mixing at this stage, as vigorous whisking can sometimes make the sour cream a bit grainy.
You just want the horseradish evenly distributed throughout the creamy base. You’ll see the white sauce speckled with the horseradish.
Step 2: Build the Creamy Body
Pour in the heavy cream, Dijon mustard, and white wine vinegar. Now, whisk again with a bit more purpose until the mixture is completely smooth and homogenous. Believe me, the Dijon will disappear into the mix, but its job is crucial.
You’ll notice the sauce will immediately loosen up and become beautifully creamy and cohesive. This is the foundation of your signature steakhouse sauce.
Step 3: Season and Taste Critically
Season the sauce with kosher salt and freshly ground black pepper. Whisk to incorporate. Now, taste it.
This is the most important step in the entire process. Trust me, the flavor and heat level of prepared horseradish can vary dramatically from brand to brand. Your palate is your best tool.
Adjust with more salt, a tiny touch more vinegar for brightness, or—most commonly—more horseradish if you want a stronger, spicier kick.
Step 4: The Essential Rest
For the absolute best flavor, cover the bowl tightly with plastic wrap and refrigerate for at least 30 minutes before serving. I know it’s tempting to use it right away, but believe me, this resting time is non-negotiable. It allows the sharp, pungent notes of the horseradish to mellow slightly and marry with the creamy, tangy elements, creating a more complex and rounded flavor profile that is far superior to freshly mixed sauce.
Step 5: Garnish and Serve with Pride
To serve, give the chilled sauce a quick stir. Transfer it to a nice serving bowl and garnish with a generous sprinkle of finely chopped fresh chives for a pop of color and a mild, fresh onion flavor. Step back and admire your perfect, creamy, restaurant-worthy condiment.
It’s now ready to transform a simple steak, prime rib, or even a roasted vegetable platter into something truly special.
A few insights from my years in professional kitchens will ensure your sauce is flawless every single time.
- Drain, Drain, Drain: The single biggest textural mistake is using undrained horseradish. The excess vinegar brine will make your sauce thin and overly acidic. Taking a minute to drain it ensures a thick, creamy, cohesive result.
- Temperature Matters: All your dairy ingredients should be cold, straight from the fridge. This helps the sauce stay fresh longer and maintains its structure. There’s no benefit to room-temperature ingredients here.
- The Flavor Development Curve: The horseradish heat will be most pronounced right after mixing. After the 30-minute chill, it mellows and integrates. If making it a day ahead, note that the spice level will continue to soften slightly, which is often desirable.
- Adjusting Consistency: If your sauce seems too thick after chilling, whisk in a teaspoon of cream or milk. If it’s too thin (likely from insufficient draining), you can gently fold in a tablespoon more sour cream.
- Fresh vs. Prepared: Freshly grated horseradish root will provide a cleaner, more pungent, and less vinegary heat. If using fresh, start with 1/4 cup grated and adjust upward, and you may need a touch more vinegar or lemon juice for balance.
Recipe Variations
- This classic formula is a wonderful canvas for customization. Here are a few of my favorite tested variations.
- Herb-Infused: Fold in 2 tablespoons of finely chopped fresh herbs along with the chives. Dill, tarragon, or parsley each add a wonderful, fresh dimension that pairs beautifully with fish or chicken.
- Horseradish-Mayo Blend: For a thicker, richer sauce ideal for sandwiches or as a spread, use a 50/50 blend of sour cream and full-fat mayonnaise. This creates a more stable, spreadable condiment.
- Roasted Garlic: Stir in 2-3 cloves of finely minced roasted garlic for a sweet, mellow, and deeply savory undertone. It’s incredible with roast beef.
- Citrus Zest: Add the finely grated zest of one lemon or lime to the mix. The citrus oils add a fantastic aromatic quality that brightens the sauce even further.
- Smoky Paprika: A 1/2 teaspoon of smoked paprika (not hot paprika) adds a subtle smoky depth that complements grilled meats perfectly.
- Wasabi Hybrid: For a different kind of heat, replace half of the horseradish with wasabi paste. It creates a vibrant green sauce with a distinct, clean heat.
What to Serve With This Sauce
While its destiny is intertwined with steak, this sauce’s utility stretches far beyond.
It is, of course, the classic accompaniment to Prime Rib, Filet Mignon, New York Strip, or Ribeye. Slather it on the meat or serve it on the side. For a show-stopping sandwich, spread it on crusty bread with thinly sliced roast beef, arugula, and red onion.
It’s also a phenomenal dip for crispy french fries, sweet potato fries, or roasted potato wedges. Try it as a topping for baked potatoes instead of plain sour cream, or as a refreshing condiment for grilled or roasted vegetables like asparagus, broccoli, or Brussels sprouts. For beverage pairings, the creamy spice works wonderfully with a bold Cabernet Sauvignon, a hoppy IPA, or even a crisp, non-oaked Chardonnay.
Storage & Make-Ahead Instructions
- This sauce is an excellent candidate for making ahead, as its flavor only improves.
- Refrigeration: Store in an airtight container in the refrigerator for up to 5 days. The sauce will thicken slightly as it chills. Give it a good stir before serving.
- Freezing: I do not recommend freezing this sauce. The dairy base will separate and become grainy when thawed, resulting in a broken texture.
- Make-Ahead Strategy: You can prepare this sauce up to 2 days in advance. In fact, I often recommend it. The flavors have more time to meld, creating a more harmonious and slightly mellower final product. Prepare as directed, store covered in the fridge, and garnish just before serving.
- Serving Temperature: Always serve this sauce chilled, straight from the refrigerator. This preserves its texture and freshness.
Frequently Asked Questions
Q: Can I use low-fat sour cream or Greek yogurt?
A: You can, but with caution. Low-fat sour cream may make the sauce thinner and less rich. Plain, full-fat Greek yogurt is a better substitute, but it will impart a tangier, more pronounced yogurt flavor, which will alter the classic steakhouse taste profile.
Q: My sauce is too spicy! How can I fix it?
A: Don’t worry, it’s an easy fix. Simply whisk in more sour cream, a tablespoon at a time, until the heat level is to your liking. You may need to add a tiny pinch of salt to re-balance the seasoning.
Q: How can I tell if my prepared horseradish is still good?
A: Fresh, refrigerated prepared horseradish should have a clean, pungent smell and a creamy white color. If it has darkened significantly, developed an off odor, or shows any signs of mold, discard it. An unopened jar can last for months in the fridge, but once opened, use it within 3-4 weeks for the best flavor.
Q: Why is my sauce watery or thin?
A: This is almost always due to not draining the prepared horseradish thoroughly. The brine is mostly vinegar and water. For a quick fix, you can drain the finished sauce in a fine-mesh strainer for a few minutes, or gently fold in an extra tablespoon of sour cream to thicken it.
Q: Can I make this sauce vegan?
A: Yes, with some substitutions. Use a thick, plain vegan sour cream alternative and a vegan heavy cream substitute (like canned coconut cream, shaken well). The flavor will be different but can still be quite good.
Ensure your prepared horseradish is vegan (most are).
Q: Is this sauce gluten-free?
A: Absolutely. All the ingredients listed—sour cream, horseradish, cream, mustard, vinegar—are naturally gluten-free. Always double-check the labels on your prepared horseradish and Dijon mustard to ensure no gluten-containing additives were used.
Q: What’s the difference between prepared horseradish and cream-style horseradish?
A: Prepared horseradish is grated horseradish root preserved in vinegar and salt. Cream-style horseradish has a dairy base (like sour cream or mayonnaise) already mixed in. For this recipe, you want prepared horseradish so you can control the creaminess and balance yourself.
