Steak and Horseradish Crostini is a simple, yet stunning appetizer recipe served warm, or room temperature topped with balsamic glaze!
Season the steak well with kosher salt and pepper. Preheat a cast iron skillet or Blackstone griddle to medium heat for several minutes.
Add some olive oil and the steaks. Cook 3 to 4 minutes per side for medium rare to medium doneness. Let the steaks rest for a few minutes and slice them into strips.
Note: I let my steak rest while making the crostini.
Slice the French Baguette into about 20 slices and place them on a baking sheet. Brush or spray the tops with olive oil and season with kosher salt and pepper. Bake in a 400-degree oven for 5 minutes.
Top each slice of bread with horseradish sauce, a slice of steak, drizzle the balsamic glaze over top and sprinkle the parsley over the crostini.
Note: These can be assembled an hour before serving. They are good at room temperature, or you can put them in the oven for a few minutes to warm them before serving.
