Stop serving boring beef. Make this bold, tangy, steakhouse-quality creamy horseradish sauce in just five minutes. It is the perfect topping for prime rib, roast beef, or steak, and works well as a zesty dipping sauce.

Ingredients

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

Instructions

  1. Drain the prepared horseradish well to remove excess liquid. This step prevents a watery sauce.
  2. In a medium bowl, combine the sour cream, drained horseradish, Dijon mustard, and lemon juice.
  3. Stir the ingredients together until they are fully incorporated and the sauce is smooth.
  4. Season the sauce with salt and pepper. Mix again to distribute the seasoning.
  5. Taste the sauce. If you want more heat, add a small amount of extra horseradish.
  6. Cover the bowl and chill the sauce for at least 15 minutes before serving. Chilling allows the flavors to blend.
  7. Serve this tangy sour cream dip with roast beef, steak, or use it for your next sandwich.

Notes

  • For a thicker sauce, use less of the liquid from the drained horseradish, or substitute some sour cream with mayonnaise for a richer texture.
  • If you are making this ahead of time, wait to add the salt until just before serving, as salt can sometimes thin out dairy-based sauces over long chilling periods.
  • This recipe delivers a bold, zesty flavor profile similar to what you find in a top steakhouse horseradish sauce.
