Welcome! You need a bold, tangy sauce for your roast beef or steak. This easy, homemade creamy horseradish sauce comes together in just five minutes using simple ingredients. It delivers that classic steakhouse flavor instantly.

Ingredients

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

Instructions

  1. In a medium bowl, combine the sour cream and mayonnaise. Mix until smooth.
  2. Add the drained prepared horseradish, Dijon mustard, salt, and pepper to the bowl.
  3. Stir all ingredients together until fully combined and creamy.
  4. Taste the sauce and adjust salt or horseradish if you desire more heat.
  5. Cover the bowl and chill the sauce for at least 15 minutes before serving to allow the flavors to blend.
  6. Serve this zesty beef topping with prime rib, roast beef, or steak.

Notes

  • Drain the prepared horseradish well; excess liquid makes the sauce thin.
  • For a flavor similar to Ina Garten’s recipe, use high-quality ingredients.
  • This sauce is best served cold.
  • You can substitute half of the sour cream with heavy cream for a lighter texture.
