Make impressive gourmet party bites quickly with this easy steak crostini recipe. It combines tender seared steak, a zesty horseradish cream, and a sweet balsamic drizzle on crispy baguette slices for a savory toast that disappears fast at any gathering.

Ingredients

Scale
  • 1 pound strip steak or filet mignon, room temperature
  • 1 teaspoon kosher salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon garlic powder
  • 1 tablespoon olive oil
  • 1 baguette, sliced 1/2 inch thick on a diagonal
  • 1/2 cup sour cream or Greek yogurt
  • 2 tablespoons prepared horseradish
  • 1 tablespoon fresh chives, chopped
  • 2 tablespoons balsamic vinegar
  • 1 teaspoon brown sugar
  • Optional: Caramelized onions or goat cheese for topping

Instructions

  1. Prepare the steak: Rub the steak with salt, pepper, and garlic powder. Heat olive oil in a skillet over medium-high heat. Sear the steak for 3 to 4 minutes per side for medium-rare. Remove the steak and let it rest for 10 minutes before slicing thinly against the grain.
  2. Make the balsamic glaze: Combine balsamic vinegar and brown sugar in a small saucepan. Bring to a simmer over medium heat and cook until the liquid reduces by half and coats the back of a spoon, about 5 to 7 minutes. Set aside to cool slightly.
  3. Toast the crostini: Preheat your oven to 375 degrees Fahrenheit. Arrange the baguette slices on a baking sheet. Bake for 8 to 10 minutes, flipping halfway through, until golden brown and crisp.
  4. Prepare the horseradish cream: In a small bowl, mix the sour cream, prepared horseradish, and chopped chives until combined.
  5. Assemble the appetizer: Spread a small amount of horseradish cream onto each toasted crostini slice. Top with a thin slice of the rested steak. Drizzle with the balsamic glaze.
  6. Serve immediately, or top with optional caramelized onions or goat cheese for extra flavor.

Notes

  • You can prepare the steak and the horseradish cream up to one day ahead. Store them separately in the refrigerator.
  • To save time, buy pre-made balsamic glaze from the store.
  • If you are making this for a crowd, arrange the components on a platter and let guests assemble their own steak crostini.
