I have made the same beef tenderloin recipe for over 20 years and it has become a tradition whether served whole at Christmases and family celebrations or as beef sandwiches and sliders at graduation parties and game day gatherings. And it’s always accompanied by a big bowl of this horseradish mustard sauce.

And homemade blue cheese dressing. Because I like options and believe that if one sandwich sauce is good, two are better.

⇢ Other easy condiment recipes like this you’ll ♥️: olive oil bread dip, pesto mayonnaise, and easy balsamic glaze. Or give my mascarpone ranch a try along …so good!

What you’ll eat with mustard horseradish sauce

So many good things:

• Swap out the pesto in this juicy chicken sandwich
• Drizzle over spicy chicken salad
• Serve as a dipping sauce for Buffalo chicken pizza

5 simple ingredients

Here’s what to gather from the pantry:

2 steps to horseradish mustard sauce

1. To a medium bowl, add the sour cream, horseradish and mustard. Stir it all together.
2. Season with salt and pepper and taste. Correct as necessary.

Can it be any easier?

Recipe notes

• If you don’t have prepared horseradish (which is closest to fresh), you can use creamy horseradish.
• For maximum flavor, mix the spread up to 4 hours ahead.
