Ingredients

Scale
  • 1 pound New York Strip or Tri-Tip steak
  • 1 teaspoon kosher salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon garlic powder
  • 1 baguette, sliced diagonally into 1/2-inch pieces
  • 2 tablespoons olive oil
  • 1/2 cup sour cream or Greek yogurt
  • 2 tablespoons prepared horseradish
  • 1 tablespoon Dijon mustard
  • 1/4 cup balsamic glaze (store-bought or homemade)
  • Fresh chives, chopped, for garnish

Instructions

  1. Season the steak evenly with salt, pepper, and garlic powder.
  2. Cook the steak using your preferred method (grill or pan-sear) until it reaches your desired doneness. Let the steak rest for 10 minutes before thinly slicing against the grain.
  3. Preheat your oven to 375°F (190°C). Brush both sides of the baguette slices lightly with olive oil.
  4. Arrange the bread slices on a baking sheet and toast for 6 to 8 minutes, flipping halfway, until golden brown and crisp. Set aside.
  5. Prepare the horseradish cream by mixing the sour cream, prepared horseradish, and Dijon mustard in a small bowl until smooth.
  6. To assemble the steak crostini, spread a small amount of horseradish cream onto each toasted baguette slice.
  7. Top the cream with a few thin slices of the cooked steak.
  8. Drizzle the balsamic glaze over the steak on each crostini.
  9. Garnish with fresh chopped chives before serving immediately.

Notes

  • For a gourmet touch, substitute the steak with filet mignon.
  • If you do not have balsamic glaze, you can reduce balsamic vinegar in a small saucepan over medium heat until it thickens enough to coat the back of a spoon.
  • You can prepare the steak and the horseradish cream up to one day ahead to save time when entertaining.
