Ingredients

Scale
  • 1 baguette, sliced into 1/2-inch thick pieces
  • 2 tablespoons olive oil
  • 1 pound sirloin or filet mignon steak
  • Salt and black pepper to taste
  • 1/2 cup sour cream or Greek yogurt
  • 2 tablespoons prepared horseradish sauce (adjust to your spice preference)
  • 1 teaspoon Dijon mustard
  • 1/4 cup balsamic vinegar
  • 1 tablespoon brown sugar (optional, for thicker glaze)
  • Fresh rosemary or basil, chopped, for garnish

Instructions

  1. Preheat your oven to 375°F (190°C). Brush both sides of the baguette slices lightly with olive oil. Arrange them on a baking sheet and toast for 8 to 10 minutes, flipping halfway, until golden brown and crisp. Set aside.
  2. Season the steak generously with salt and pepper. Cook the steak in a hot skillet to your desired doneness (medium-rare is recommended for tenderness). Remove the steak from the heat and let it rest for 5 minutes before thinly slicing against the grain.
  3. Prepare the horseradish cream: In a small bowl, whisk together the sour cream, prepared horseradish, and Dijon mustard until smooth.
  4. Make the balsamic glaze: Combine the balsamic vinegar (and brown sugar, if using) in a small saucepan. Bring to a simmer over medium heat and cook, stirring occasionally, until the vinegar reduces by about half and coats the back of a spoon (about 5-7 minutes). Remove from heat.
  5. Assemble the steak crostini: Spread a small amount of horseradish cream onto each toasted baguette slice. Top with a few thin slices of steak. Drizzle lightly with the balsamic glaze.
  6. Garnish with fresh chopped rosemary or basil before serving these savory small bites immediately.

Notes

  • For an extra layer of flavor, you can top the steak with caramelized onions or a slice of Brie cheese before the glaze.
  • If you are preparing these for a crowd, you can toast the bread and make the sauces ahead of time. Assemble just before serving to keep the crostini crisp.
