Servings 6 to 10 servings


  • 1/4 cup mayo
  • 1/4 cup sour cream
  • 1 tbl horseradish
  • 4 tsp Dijon Mustard
  • Salt and pepper to taste
  • Crusty Baguette
  • 1/2 pound Roast Beef thinly sliced
  • Microgreens or chives
  • Capers
  • Freshly grated parmesan cheese


  • Preheat oven to 350 degrees. Arrange your baguette slices on two large rimmed baking sheets; brush both sides with oil, and season with salt and pepper.
  • Bake until golden, 15 to 20 minutes, rotating sheets halfway through (if undersides are not browning, turn crostini over once during baking).
  • Spread a tablespoon of the horseradish dijon onto a toast.
  • Top with a slice of roast beef.
  • Top with a small dollop of more Maille Dijon Horseradish sauce, a few capers and some microgreens if you’d like (these are just for presentation).
  • Add a few crumbles of freshly grated parmesan cheese for another layer of flavor (optional)
