Ingredients
This Fresh Horseradish Sauce Recipe relies on just five simple pantry staples that work together beautifully. For the creamy base — mayonnaise and sour cream — you’ll want to use whatever fat percentage makes you happy (low-fat works great if that’s your thing).
The prepared horseradish brings all the punchy flavor, while Worcestershire sauce and kosher salt tie everything together with that savory, umami depth.
| Amount | Ingredient |
|---|---|
| 1/4 cup | Mayonnaise (low-fat works great) |
| 1/4 cup | Prepared horseradish (see notes below about choosing the right kind) |
| 2 tablespoons | Sour cream (I used low-fat — totally your call) |
| 1 teaspoon | Worcestershire sauce |
| 1/2 teaspoon | Kosher salt (or 1/4 teaspoon table salt) |
Important note about horseradish: You want the kind that comes in a jar in the refrigerated section — it’s white, creamy, and already grated.
Don’t grab the horseradish root from the produce section unless you’re feeling adventurous and own a really good grater. The prepared stuff is perfect here and saves you tears (literally — fresh horseradish is intense).
Tools You’ll Actually Use

Pro Tips & Gentle Guidance
Here’s what I’ve learned making this Easy Horseradish Sauce about a million times for family dinners and casual weeknight meals.
The horseradish flavor gets stronger as it sits, so if you’re making this ahead, start with slightly less horseradish than you think you need. You can always stir in more later, but you can’t take it back once it’s in there.
Low-fat mayo and sour cream work beautifully if you’re watching calories, but full-fat versions make the sauce extra silky and rich. Either way tastes amazing, so use what you have or what fits your eating style.
If you want to get fancy, try adding a tiny squeeze of fresh lemon juice (about 1/2 teaspoon) for brightness, or a pinch of cayenne pepper if you like things extra spicy. I also love stirring in a teaspoon of Dijon mustard for more complexity.
If you’re new to working with horseradish in homemade sauces, The Spruce Eats has a detailed guide on selecting and storing prepared horseradish that I reference all the time. It’s super helpful for understanding how to get the best flavor.
Let the sauce sit in the fridge for at least 15-20 minutes before serving if you have time. The flavors meld together and it gets even better as it chills.
Quick Fixes for Homemade Horseradish Sauce
Even though this recipe is basically foolproof, here are solutions to the few things that might go slightly sideways.
Problem: The sauce tastes too spicy and makes your eyes water. Solution: Stir in another tablespoon of sour cream or mayo to mellow it out. You can also add a tiny pinch of sugar (like 1/4 teaspoon) to balance the heat without making it taste sweet.
Problem: The sauce is too thick and gloppy. Solution: Thin it out with a teaspoon of milk, cream, or even a splash of pickle juice for extra tang. Add liquid slowly and whisk until you reach your preferred consistency.
Problem: The flavor tastes flat or boring. Solution: You probably need more salt. Start with another 1/4 teaspoon and taste again. Sometimes a squeeze of lemon juice or an extra dash of Worcestershire sauce perks everything right up.
Problem: The horseradish flavor faded after a few days in the fridge. Solution: This is normal — prepared horseradish loses its punch over time once the jar is opened. Just stir in a fresh tablespoon of horseradish to bring back that zingy kick.
Variations & Adaptations
This Fresh Horseradish Sauce Recipe is incredibly versatile, so feel free to make it your own.
For a lighter version: Use Greek yogurt instead of sour cream and light mayo. You’ll get extra protein and tanginess with fewer calories.
For dairy-free horseradish sauce: Swap in vegan mayo and use coconut cream or cashew cream in place of the sour cream. The flavor is slightly different but still delicious.
For a creamy dill horseradish sauce: Stir in 1-2 tablespoons of fresh chopped dill and a squeeze of lemon. This version is incredible with salmon or on a roast beef sandwich with arugula.
For cocktail sauce vibes: Mix in 2 tablespoons of ketchup and a squeeze of lemon juice. Now you’ve got a homemade shrimp cocktail sauce that’ll blow the bottled stuff out of the water.
For extra heat: Add 1/4 teaspoon of cayenne pepper, a dash of hot sauce, or a bit of freshly grated horseradish root if you can find it. Just be warned — it’s potent.
Serving, Storage & Reheating
This Homemade Horseradish Sauce is best served cold or at room temperature, so pull it from the fridge about 10 minutes before serving if you want the flavors to really shine.
It’s perfect on prime rib, roast beef sandwiches, grilled steak, or even as a zesty dip for veggies and blueberry cream cheese bars — okay, maybe not that last one, but you get the idea.
Store your sauce in an airtight container in the refrigerator for up to one week. The horseradish flavor will get stronger on day two and three, then gradually mellow out by day five or six. Give it a quick stir before using since the ingredients might separate slightly.
There’s no reheating needed here — this sauce is meant to be enjoyed cold or at cool room temperature. If you somehow manage not to eat it all at once, just make sure you keep it refrigerated between uses.
No-Waste Kitchen Magic
Got leftover horseradish sauce? Here are some creative ways to use every last drop instead of letting it go to waste.
Mix a spoonful into mashed potatoes for a flavor bomb side dish. Seriously, it transforms boring mashed potatoes into something people will ask for the recipe.
Use it as a spread on your morning breakfast sandwich with eggs and bacon. The tangy kick is incredible with runny egg yolks.
Stir it into tuna salad, chicken salad, or egg salad for sandwiches with way more personality. Just a tablespoon or two makes everything taste gourmet.
Thin it out with a little milk or buttermilk and use it as a salad dressing for bitter greens like arugula or radicchio. The creaminess balances the bitterness perfectly.
Mix it with some softened butter and use it to make compound butter for steaks. Freeze it in a log shape, slice, and melt over hot meat. You’re welcome.
Fresh Horseradish Sauce Recipe FAQs
Can I freeze this Homemade Horseradish Sauce?
I wouldn’t recommend it. The mayonnaise and sour cream will separate and get watery when thawed, giving you a weird, grainy texture that’s just not pleasant. This sauce is so quick to make that you’re better off whipping up a fresh batch whenever you need it.
What’s the best way to store Homemade Horseradish Sauce for Prime Rib?
Keep it in an airtight container in the fridge and it’ll stay fresh for about a week. Make sure you’re using a clean spoon every time you scoop some out to prevent any contamination. If it starts to smell funky or you see any discoloration, toss it and make a new batch.
How do I know when my horseradish sauce has the right consistency?
It should be thick enough to dollop but spreadable, kind of like a loose mayonnaise or ranch dressing. If you dip a spoon in and it coats the back without immediately running off, you’ve nailed it. Too thick? Add a splash of milk. Too thin? Whisk in a bit more mayo or sour cream.
Why should I use prepared horseradish in Homemade Horseradish Sauce instead of fresh root?
Prepared horseradish is already grated, preserved in vinegar, and has a consistent heat level — which makes this recipe super reliable and quick.
