Ingredients
Scale
1 cup sour cream
1/2 cup prepared horseradish, drained
2 tablespoons mayonnaise
1 teaspoon Dijon mustard
1/2 teaspoon salt
1/4 teaspoon black pepper
1 teaspoon fresh lemon juice
Instructions
Drain any excess liquid from the prepared horseradish. This step is key for a thick sauce.
In a medium bowl, combine the sour cream, drained horseradish, mayonnaise, and Dijon mustard.
Stir the ingredients together until they are fully mixed and the sauce is smooth.
Season the sauce with salt, black pepper, and fresh lemon juice. Stir again to combine the seasonings.
Taste the sauce. If you want more heat, add a small amount of extra horseradish. If you want it tangier, add a few drops more lemon juice.
Cover the bowl and chill the sauce in the refrigerator for at least 15 minutes before serving. This allows the flavors to blend.
Serve this tangy steak sauce with prime rib, roast beef, or as a quick horseradish dip.
Notes
For an Ina Garten inspired version, you can substitute some of the sour cream with heavy cream for a slightly richer texture.
This sauce is best when made ahead of time, allowing the horseradish flavor to fully develop.
If you only have fresh horseradish, grate it finely and use about 2 tablespoons, adjusting to your heat preference.
