  • ⅔ cups (150 ml) vegetable oil
  • ½ teaspoon sugar

  3. Spread the four slices of bread on one side with the prepared mayonnaise.

Horseradish has a way of provoking your palate by making you enjoy and feel each flavor! We’ve chosen to show you how to make a unique sauce that also contains sour cream, which blunts the strong pungency of the horseradish! See detailed instructions on how to make the sandwiches below:


  • 1 cup arugula
  • 4 brioche buns
  • 1 tablespoon of olive oil
  • 1 small onion, sliced
  • 2 cloves garlic, minced
  • 1 tablespoon (14 g) butter
  • salt and pepper to taste
  • 1/2 pound sliced roast beef

For the horseradish cream sauce:

  • 1/4 teaspoon horseradish
  • 2 tablespoons mayonnaise
  • 2 tablespoons sour cream
  • 1 tablespoon Dijon mustard
  • kosher salt and pepper to taste


  1. Start by preparing the horseradish cream sauce. Mix all ingredients in a bowl – horseradish, mayonnaise, sour cream, Dijon mustard, kosher salt and pepper. Cover the bowl with foil and let the sauce sit for about 10-15 minutes. During this time, prepare everything else for the sandwiches.
  2. Add olive oil and butter to a skillet and set over medium heat. Once the butter has melted, add the onion and garlic. The onions should caramelize, which takes about 10 minutes. Be sure to stir periodically. Once the onions and garlic are golden brown, remove them from the heat and set aside.
  3. Cut the brioche buns in half and place them on a baking sheet in a baking pan. Brush each half with the horseradish sauce. Put the roast beef on only two of the halves, dividing the meat equally between the sandwiches. Then place the caramelized onions evenly over the meat. Put arugula on top of the other two halves of the buns.
  4. Carefully assemble the top and bottom of the sandwiches and pop them in the oven at about 212°F (100°C) for 2-3 minutes.
  5. Remove from the oven and serve! Bon Appetit!
