House of Prime Rib Horseradish Recipe made me stop and put down my fork the first time I tried it. I always thought a good prime rib dinner was about the meat alone, until this sauce showed me otherwise.
For years I figured rich, creamy steakhouse sauces were a secret nobody could copy at home. Then I tasted this famous sauce, and my mind changed on the spot.
It felt smooth and creamy, with a tangy richness, then that horseradish kick woke up every bite of tender beef without taking over. I couldn’t get it out of my head, so I went into my kitchen and built my own version.
With everyday items like sour cream, mayonnaise, and prepared horseradish, you can build a steakhouse-style sauce in a few minutes. Every spoonful comes out rich, smooth, and balanced, making it the ideal match for a juicy slice of prime rib.
Why You’ll Love This House of Prime Rib Horseradish
This recipe brings steakhouse flavor to your table quickly. The sauce is creamy and smooth, with a mild heat that isn’t too strong. You can find all the ingredients at a regular grocery store, so no special shopping is needed.
This sauce is perfect for holiday dinners, weeknight steaks, or dinner parties, and even beginner cooks can make it easily on their first try.
Choosing the right horseradish is key for the best taste. Prepared horseradish in a jar with vinegar works best because it is consistent and mild.
Fresh horseradish root is sharper in taste and needs grating, which takes more time. Beet horseradish is sweeter and milder, with a deep red color. Pink horseradish is a lighter, softer option.
What Makes House of Prime Rib Horseradish Sauce Unique?
This horseradish sauce stands out because of its whipped texture. Instead of being thick and heavy, it is light and airy, resembling a soft cloud next to your meat. This whipped style keeps the sauce rich without weighing down the plate.
The cream and mayonnaise balance the heat, so the horseradish wakes up your senses without burning your mouth. Each bite is creamy and smooth, never grainy or thin.
This sauce is a perfect match for prime rib because the meat’s richness needs something bright to cut through the fat. The tangy, peppery kick balances a fatty cut of beef and prevents each bite from feeling too heavy.
At the original steakhouse, servers bring the sauce in a small dish with the meat, letting guests spoon on as much or as little as they like. This approach also works well at home, giving everyone control over how much heat they want.

House of Prime Rib Horseradish vs. Other Horseradish Sauces
Classic creamy horseradish sauce is usually thick, but this lighter version is whipped. It has a tangy flavor that highlights the horseradish, unlike sweeter sauces found at steakhouses.
Making your own sauce is fresher than buying it from the store. You can control the heat and avoid preservatives. Prepared horseradish, mixed with vinegar and salt, has a steady heat. Fresh horseradish root is sharper but loses its flavor quickly after grating, so use it right away.
Whipped horseradish sauce with cream is lighter than thick mayonnaise-based sauces. Jarred plain prepared horseradish is harsher than this whipped version, which includes more ingredients.
Regular whipped horseradish stays pale and cream-colored. Pink beet horseradish gets its color and sweeter taste from added beets. Traditional steakhouses serve plain whipped horseradish, so it’s best to use that for an authentic dish.
Is This the Authentic House of Prime Rib Recipe?
This recipe is similar to the one from the famous San Francisco steakhouse, but it is not their secret. It has the tangy taste, smooth texture, and balanced heat you expect. To make a light and fluffy sauce, use the right technique.
For small batches, whisk by hand. For larger batches, a hand mixer works better and adds more air. When adding whipped cream, use a spatula and be gentle. Avoid stirring too hard, as that can make the sauce flat.
Chill your bowl and beaters before whipping the cream. Cold tools help the cream hold its shape. Use a lighter mayo for better blending and to prevent a dense sauce. If you enjoy beets, try adding a spoonful of beet horseradish for color and a milder taste.
Ingredients for House Of Prime Rib Horseradish
Sour cream (½ cup): This gives the sauce a cool, tangy base and balances the sharp taste of horseradish. You can use full-fat Greek yogurt instead for a similar flavor with more protein.
Mayonnaise (½ cup): Mayo adds richness and makes the sauce smooth and creamy when whipped. Light or avocado oil mayo also works well, keeping the texture silky.
Prepared horseradish (3 to 4 tablespoons, drained): This is the main flavor in the sauce. Grated fresh horseradish root, about 2 tablespoons, can give a sharper taste for those who like more heat.
Heavy cream (2 tablespoons, whipped to soft peaks): Whipped cream folded in gives the sauce a light, airy texture. Coconut cream can also be whipped for a dairy-free option that still adds fluffiness.
Apple cider vinegar (1 teaspoon): A splash of vinegar brightens the sauce and balances its richness. You can use white wine vinegar or plain white vinegar if you don’t have apple cider vinegar.
Dijon mustard (1 teaspoon): Mustard adds tang and extra depth. You can substitute yellow mustard for a milder flavor.
Cayenne pepper (¼ teaspoon): A pinch of cayenne adds gentle heat to the sauce. Smoked paprika can be used for warmth without the sharpness.
Salt and black pepper (to taste): These essentials tie all the flavors together and ensure the sauce tastes good.
Tools I Use to Make This Horseradish
- Mixing bowl: Holds all the ingredients.
- Hand mixer: Whips cream quickly.
- Rubber spatula: Gently folds ingredients together.
- Measuring cups: Give exact amounts of liquids.
- Measuring spoons: Provide precise amounts for horseradish and spices.
- Whisk: Helps mix by hand if needed.
- Airtight container: Keeps sauce fresh.
How to Make House of Prime Rib Horseradish Sauce
1. Whip the Cream: Pour heavy cream into a cold mixing bowl. Use a hand mixer to beat the cream until it forms soft peaks. This will take about one to two minutes. Stop when the cream holds its shape; if you whip it too much, it will become grainy and stiff.

2. Mix the Creamy Base: In a different bowl, combine sour cream, mayonnaise, Dijon mustard, and apple cider vinegar. Stir until smooth. This mixture adds tang and creaminess to the sauce.

3. Add the Horseradish and Spices: Mix in prepared horseradish, cayenne pepper, salt, and black pepper into the creamy base. Stir just until everything is blended; avoid mixing too much.

4. Fold in the Whipped Cream: Add the whipped cream to the horseradish mixture in two parts. Gently fold it in with a rubber spatula, turning the bowl as you mix, until there are no white streaks left. Folding keeps the sauce light and airy.
5. Chill Before Serving: Cover the bowl and refrigerate the sauce for at least one hour. This helps the flavors blend and makes the sauce smoother and more balanced for your meal.

Tips, Tricks, and Common Mistakes to Avoid
Sauce too runny: If your horseradish is too wet, it can make the sauce thin. Squeeze out excess liquid before mixing it in.
Sauce separates: This happens when you mix cold and room-temperature ingredients. Keep your dairy cold while you work to keep the sauce smooth.
Sauce too spicy: If your sauce is too spicy, reduce the horseradish. Start with two tablespoons and add more slowly if needed.
Sauce too bland: If the sauce lacks flavor, it likely needs more salt or a bit more vinegar. Taste it as you go and make small adjustments.
Too much mayonnaise: Using too much mayonnaise can make the sauce heavy. Stick to the recipe and let the sour cream balance it out.
Overmixing: Mixing too vigorously or for too long can deflate whipped cream. Fold gently and stop as soon as everything is combined.
Skipping chilling: If you serve the sauce right away, it may not taste as good. Chill it in the fridge for at least an hour for better flavor.
Using watery horseradish: Some jarred horseradish contains extra liquid. Drain it well using a fine mesh strainer before measuring.
Overwhipping cream: If you whip cream too long, it can become grainy and clumpy. Watch it closely and stop when you see soft peaks.
Delicious Variations on House Of Prime Rib Horseradish

Keto Version: Use lemon juice instead of vinegar and stick to full-fat mayo and sour cream to keep it low-carb.
Low-Fat Version: Choose light mayo and low-fat sour cream, and use half-and-half instead of heavy cream.
Gluten-Free Version: This sauce is naturally gluten-free. Just check your mustard and horseradish for hidden additives.
Dairy-Free Version: Use whipped coconut cream along with dairy-free mayo and sour cream to keep it plant-based.
Herb Version: Add a teaspoon of chopped fresh chives or dill for a fresh taste.
Garlic Version: Mix in a small clove of grated garlic for extra flavor.
Customizing the Heat Level: Adjust the horseradish to control the heat. Use two tablespoons for mild, three for medium, four for hot, and five or more for extra hot.
Best Ways to Serve House of Prime Rib Horseradish
This sauce is great with warm prime rib, but you can use it in many other ways. Try it on roast beef, grilled ribeye steak, or beef tenderloin for a tasty kick. It makes a roast beef sandwich or French dip sandwich really special, especially if you spread a little on the bun before adding the meat.
You can also add a spoonful to a juicy burger, serve it with roasted vegetables, or put it next to a warm baked potato for a fresh, tangy flavor. When serving au jus, both sauces work well together.
Guests can dip their meat in the au jus first and then add the horseradish sauce for more flavor. For a restaurant-style look, instead of spreading, place a small spoonful or a neat shape of sauce on the plate next to the meat for a polished appearance.

Can Horseradish Be Used as More Than a Sauce?
This sauce is more than just a side dish. Use a thin layer on bread for sandwiches instead of regular mayo for extra flavor. Mix a spoonful into a beef rub or use it as part of a crust for prime rib to enhance the flavor.
Stir a little into deviled egg filling for a tangy twist on a classic snack. Fold a spoonful into mashed potatoes to add flavor that pairs well with beef dinners.
Roast beef sliders taste amazing with this sauce instead of regular condiments. It also serves as a great dipping sauce for fries, roasted meats, or fresh vegetables.
Storage and Make-Ahead Tips
Store the sauce in an airtight container in the refrigerator. It will stay fresh for about 5 to 7 days. Avoid freezing it, as the dairy can separate and become watery once thawed, ruining its smooth texture.
Before serving, give the sauce a quick stir, as some separation may happen during storage. The flavor improves after a few hours in the fridge, as the horseradish, mustard, and vinegar mix well together.
For the best taste, make this sauce one full day before your dinner to develop the deep, tangy flavor everyone enjoys.
