If there's one thing that can make or break a beef roast dinner, it's the sauce sitting next to it. This Creamy Horseradish Sauce comes together in about a minute, with sour cream, prepared horseradish, a touch of Dijon, white balsamic vinegar, fresh chives, and lemon zest. It's bold without being aggressive, tangy without being sharp, and it pairs beautifully with any beef roast on the table. Our rule: if the bowl is empty before dinner is over, it's a good batch. We've never had a bad one.

The Horseradish Cream Sauce That Actually Keeps Up With the Main Course ✨

We started making this sauce because jarred horseradish cream was always a little… sad. 🫠Too mild to bother with, and the tang just tastes like vinegar instead of anything interesting. When you're putting a slow cooker prime rib roast on the table, the sauce alongside it should actually keep up with the main event!

What makes this version work is the balance. Prepared horseradish brings the heat and the distinctive sharpness, but the sour cream base rounds it out immediately. The lighter, less assertive flavor of white balsamic adds brightness without fighting the horseradish for attention. A little lemon zest and fresh chives finish it off, and the result is a horseradish cream sauce that tastes like something you'd get at a steakhouse, not something that's been sitting in a jar since October. 😉

It's also the sauce we always make ahead and pull out of the fridge just before the prime rib comes out of the slow cooker. It mellows just a little as it sits, which is actually a good thing - the flavors knit together, and the sharpness settles into something more nuanced. It also works beautifully as a condiment for leftover prime rib sandwiches the next day. Basically: if beef is on the table, this sauce belongs on it.

How to Make Horseradish Cream Sauce ✨

Don't overthink this one. It's a bowl, a spoon, and a minute of your time.

sour cream, mayo, chives, lemon zest, dijon mustard, vinegar, and horseradish in a bowl.

Step 1: Add the sour cream, mayonnaise, prepared horseradish, Dijon, white balsamic vinegar, chives, and lemon zest to a bowl. Don't add salt and pepper yet!

💡 Drain your horseradish first. Prepared horseradish can have a lot of liquid sitting at the top of the jar. Drain off the excess before measuring, so the sauce doesn't end up too watery.

🍊 White balsamic, not regular. White balsamic is milder and less sweet than traditional balsamic, and it lifts the sauce without overpowering the horseradish. In a pinch, a splash of white wine vinegar works; just use less, since it's sharper.

Step 2: Stir to combine, then add salt and pepper to taste. If you want an extra kick of heat, add more horseradish. For more brightness, add a touch more vinegar.

🧄 Want to add garlic? A small clove of fresh garlic, finely grated, really works to make this a creamy garlic horseradish sauce! Add it in Step 1 and let it mellow during the rest time.

💡 Want a looser consistency? Add a splash of milk or cream, a teaspoon at a time, until it reaches the texture you're after.

Step 3: Cover and refrigerate for at least 15 minutes before serving. The sauce tastes better after a short rest, allowing the flavors to settle and the heat to mellow slightly.

❄️ Make it ahead. This sauce keeps well in the refrigerator for up to a week in an airtight container. We always make it the day before a big dinner and pull it straight from the fridge to the table. It's best served cold with a roast, anyway!

Garnish with fresh chives before serving.

What to Serve With Creamy Horseradish Sauce 🍽️

This sauce was built for beef. The most natural pairing is our slow cooker prime rib; it's the dish that makes this sauce necessary.

It's also excellent alongside a chuck roast in the oven for weeknight roast beef dinners, (and this slow cooker sirloin tip roast for a leaner cut!) or with our melt in your mouth roast beef when you want the same energy with less of a special occasion.

Cooked prime rib on plate and with some thin slices cut away from the roast, with creamy horseradish sauce covering the slices.

It's also a surprisingly great match for Dutch oven corned beef and cabbage - the sharpness cuts right through the richness of the brisket in the same way it does with prime rib!
