Ingredients

Scale
  • 1 pound beef sirloin or flank steak
  • 1 tablespoon olive oil
  • 1 teaspoon kosher salt
  • 1/2 teaspoon black pepper
  • 1 baguette, sliced into 1/2-inch rounds
  • 1 tablespoon butter, melted
  • 1/2 cup prepared horseradish
  • 1/4 cup sour cream
  • 1 tablespoon fresh chives, chopped
  • 1 teaspoon lemon juice

Instructions

  1. Prepare the steak: Rub the steak with olive oil, salt, and pepper. Sear in a hot skillet for 3 to 4 minutes per side for medium-rare. Remove the steak and let it rest for 10 minutes before thinly slicing against the grain.
  2. Toast the crostini: Brush the baguette slices lightly with melted butter. Bake at 375°F (190°C) for 6 to 8 minutes, or until golden brown and crisp.
  3. Make the horseradish cream: In a small bowl, combine the prepared horseradish, sour cream, chopped chives, and lemon juice. Mix well until smooth.
  4. Assemble the bites: Spread a small amount of horseradish cream onto each toasted crostini slice.
  5. Top each piece with a thin slice of the rested steak.
  6. Garnish with a few extra chopped chives if desired. Serve immediately.

Notes

  • For a sweeter contrast, replace the horseradish cream with caramelized onion jam or a drizzle of balsamic glaze.
  • You can prepare the steak and the horseradish cream up to one day ahead of time to save time when assembling.
  • Use a high-quality cut of beef, like filet mignon bites, for an extra gourmet feel.
