Make this easy, zesty, and creamy horseradish sauce at home. It is the perfect steakhouse copycat condiment for prime rib, roast beef, or steak, ready in under 15 minutes.

Ingredients

Scale
  • 1 cup sour cream
  • 1/2 cup prepared horseradish, drained
  • 2 tablespoons mayonnaise
  • 1 tablespoon Dijon mustard
  • 1 teaspoon lemon juice
  • 1/4 teaspoon salt
  • 1/8 teaspoon black pepper

Instructions

  1. Combine the sour cream, prepared horseradish, mayonnaise, Dijon mustard, and lemon juice in a medium bowl.
  2. Stir the ingredients together until the mixture is smooth and fully combined.
  3. Season the sauce with salt and black pepper. Stir again to incorporate.
  4. Taste the sauce. If you want a stronger flavor, add one teaspoon more of prepared horseradish.
  5. Cover the bowl and chill the horseradish sauce in the refrigerator for at least 30 minutes before serving. This allows the flavors to blend.
  6. Serve this tangy beef topping with prime rib, roast beef, or your favorite steak.

Notes

  • For a potent horseradish flavor, use fresh, freshly grated horseradish instead of prepared, but adjust liquid amounts slightly.
  • This sauce pairs well with roast beef sandwiches or as a quick horseradish dip for vegetables.
  • You can substitute half of the sour cream with heavy cream for a lighter texture.
