Ingredients

Scale
  • 1 baguette, sliced 1/2 inch thick
  • 2 tablespoons olive oil
  • 1 pound sirloin or filet mignon steak
  • Salt and black pepper to taste
  • 1/2 cup prepared horseradish
  • 1/2 cup sour cream or Greek yogurt
  • 1 tablespoon fresh chives, chopped
  • 1/4 cup caramelized onions (optional topping)
  • Balsamic glaze for drizzling (optional topping)

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.
  2. Bake the baguette slices for 8 to 10 minutes, flipping halfway through, until they are golden brown and crisp. Set the crostini aside.
  3. Season the steak generously with salt and pepper. Cook the steak in a hot skillet to your desired doneness (about 3-5 minutes per side for medium-rare). Let the steak rest for 5 minutes after cooking.
  4. While the steak rests, prepare the horseradish cream: In a small bowl, mix the prepared horseradish, sour cream (or yogurt), and chopped chives until combined.
  5. Thinly slice the rested steak against the grain into small pieces suitable for topping the crostini.
  6. Assemble the appetizers: Spread a small amount of horseradish cream onto each toasted baguette slice.
  7. Top each slice with a few pieces of sliced steak.
  8. If using, add a small amount of caramelized onions on top of the steak. Drizzle lightly with balsamic glaze.
  9. Serve immediately as impressive finger foods for your gathering.

Notes

  • For best results when slicing steak for crostini, chill the cooked steak for 10 minutes before slicing thinly.
  • You can prepare the horseradish cream and caramelize the onions a day ahead to save time when entertaining.
  • If you prefer a sweeter topping, substitute the caramelized onions with onion jam.
