Stop buying jarred sauce. Make this foolproof, creamy horseradish sauce in just 5 minutes. This tangy beef topping delivers classic steakhouse flavor and perfectly complements prime rib, roast beef, and steak.

Ingredients

Scale
  • 1 cup sour cream
  • 1/2 cup mayonnaise
  • 1/4 cup prepared horseradish (drained if very wet)
  • 1 tablespoon Dijon mustard
  • 1 teaspoon white wine vinegar
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper

Instructions

  1. In a medium bowl, combine the sour cream and mayonnaise. Stir until the mixture is smooth.
  2. Add the prepared horseradish, Dijon mustard, and white wine vinegar to the bowl. Mix well to incorporate all ingredients.
  3. Season the sauce with salt and black pepper. Stir again to distribute the seasoning evenly.
  4. Taste the creamy horseradish sauce. If you want more heat, add another teaspoon of horseradish. If you want more tang, add a few drops of vinegar.
  5. Cover the bowl and chill the sauce in the refrigerator for at least 15 minutes before serving. This allows the flavors to blend.
  6. Serve this quick creamy steak sauce alongside your favorite roast beef or prime rib.

Notes

  • For an ‘Ina Garten style sauce’ flavor, use high-quality, full-fat sour cream.
  • If you are making this ahead of time for a holiday dinner, prepare it up to 2 days in advance. The flavor deepens as it sits.
  • Drain excess liquid from the jarred horseradish before adding it to prevent the sauce from becoming too thin.
