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.
Mustard horseradish sauce is also so good with:
- in this juicy chicken sandwich
- over spicy chicken salad
- with a Buffalo chicken pizza as a dipping sauce

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.
