I know horseradish can be an acquired taste, but I just love it and the big boost of flavor it adds. Sour cream and mayo keep the sauce cool and creamy, and prepared horseradish brings a sharp little kick that wakes everything up. I like to mix it a few hours before serving so the flavors have time to settle, and I always add extra chives for a fresh pop of color. It is one of those quick sauces that instantly upgrades prime rib, steak sandwiches, and even simple roasted vegetables.
Helpful Tips
- Drain the horseradish. Make sure you fully drain the prepared horseradish. Removing the excess liquid keeps the sauce thick and creamy, and prevents it from turning watery in the fridge.
- Always taste as you go. If you want a stronger kick, stir in an extra teaspoon of horseradish until it reaches the level of heat you like.
- Chill the sauce. Chill the sauce for at least 20 to 30 minutes before serving. This short rest helps the flavors blend and gives the sauce a smoother, more balanced taste.
- If the flavor is too sharp. If the flavor feels too sharp or intense, mix in an additional tablespoon of sour cream. It softens the heat and brings everything back into balance.

How to Make Horseradish Sauce Step by Step

Add fresh chives: Stir in 1 tbsp finely chopped chives.

Serving Suggestions
This homemade horseradish sauce goes well with so many dishes, especially anything rich or savory. I love serving it with prime rib, steak sandwiches, pork tenderloin, and even simple steaks. It is also great with smoked salmon boards, deviled eggs, and sushi rolls when you want a gentler option than wasabi. Try spooning it over roasted potatoes or adding a little to egg salad or tuna salad for an extra punch of flavor. It is one of those quick condiments that works for holiday dinners, weekend meals, and everyday sandwiches.
How to Store Leftovers
Store the horseradish sauce in an airtight container and keep it in the refrigerator for up to two weeks. The flavors actually get better after a day or so as they blend together. Give it a quick stir before serving, since it can settle a bit as it chills. Freezing is not recommended because the sour cream and mayo can separate once thawed, which changes the texture.
