Make this bold, tangy, and creamy horseradish sauce at home. It delivers the perfect steakhouse flavor to complement your prime rib, roast beef, or holiday roast.

Ingredients

Scale
  • 1 cup sour cream
  • 1/2 cup heavy cream
  • 1/4 cup prepared horseradish, drained well
  • 1 tablespoon Dijon mustard
  • 1 teaspoon white wine vinegar
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon garlic powder

Instructions

  1. In a medium bowl, combine the sour cream and heavy cream. Whisk until smooth.
  2. Add the drained prepared horseradish, Dijon mustard, white wine vinegar, salt, black pepper, and garlic powder to the bowl.
  3. Whisk all ingredients together until the sauce is completely smooth and creamy.
  4. Taste the sauce. If you want more heat, add one teaspoon of horseradish at a time until you reach your desired kick.
  5. Cover the bowl and refrigerate the sauce for at least 30 minutes before serving. This allows the flavors to blend.
  6. Serve this classic prime rib accompaniment cold with your roast beef or steak.

Notes

  • Drain the prepared horseradish thoroughly. Excess liquid makes the sauce watery.
  • For a tangier, zesty horseradish dip, increase the white wine vinegar by one teaspoon.
  • You can make this sauce ahead of time; it keeps well in the refrigerator for up to one week.
  • If you prefer a thinner consistency, add one tablespoon of milk until you reach your preferred texture.
