Make this steakhouse-quality creamy horseradish sauce in just five minutes. This zesty, tangy condiment is the best sauce for prime rib, roast beef, and steak.

Ingredients

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

Instructions

  1. Gather all your ingredients. You need sour cream, mayonnaise, prepared horseradish, Dijon mustard, salt, pepper, and lemon juice.
  2. In a medium bowl, combine the sour cream and mayonnaise. Stir them together until they are fully mixed and smooth.
  3. Add the drained prepared horseradish and Dijon mustard to the bowl. Mix until these are incorporated.
  4. Stir in the salt, black pepper, and fresh lemon juice. Mix everything until the sauce has a uniform, creamy texture.
  5. Taste the sauce. If you want more heat, add a little more horseradish. If you want it tangier, add a few drops more lemon juice.
  6. Cover the bowl and chill the creamy horseradish sauce in the refrigerator for at least 15 minutes before serving. This allows the flavors to blend.
  7. Serve this zesty beef topping with your favorite roast beef, prime rib, or steak.

Notes

  • Drain the prepared horseradish thoroughly. Excess liquid makes the sauce watery instead of creamy.
  • For a copycat of Ina Garten’s style, use high-quality ingredients.
  • This sauce works well as a quick sandwich sauce for leftover roast beef.
  • You can substitute half the sour cream with heavy cream for a slightly lighter texture, though it will be less traditional.
