Equipment

  • Skillet
  • Baking sheet
  • Bread knife
  • Cutting board
  • Small mixing bowl

Ingredients

  • 12 slices baguette 1/2 inch thick
  • 2 tablespoons olive oil
  • 1 large onion thinly sliced
  • 1/2 teaspoon sugar
  • 1/2 teaspoon salt
  • 300 g beef steak such as sirloin or tenderloin
  • Salt and pepper to taste
  • 1/4 cup mayonnaise
  • 1 tablespoon prepared horseradish
  • 1 teaspoon lemon juice
  • 1/2 cup microgreens

Instructions

  • Preheat your oven to 350°F (175°C).
  • Brush both sides of the baguette slices with olive oil and place them on a baking sheet. Toast in the oven for 10-15 minutes or until golden and crisp. Remove and set aside.
  • Heat 1 tablespoon of olive oil in a skillet over medium heat. Add the sliced onions, sugar, and 1/2 teaspoon of salt. Cook, stirring occasionally, for 20-25 minutes until the onions are caramelized. Remove from heat and set aside.
  • Season the steak with salt and pepper. In the same skillet, add a touch more oil if needed, and cook the steak over medium-high heat to your desired doneness, about 2-3 minutes per side for medium-rare. Let it rest for 5 minutes and then slice thinly against the grain.
  • In a small bowl, mix together the mayonnaise, horseradish, and lemon juice to make the horseradish mayo.
  • Assemble the crostini by spreading a layer of horseradish mayo on each toasted baguette slice, followed by a spoonful of caramelized onions.
  • Place a slice or two of the steak on top of the onions, and garnish with microgreens.
  • Serve immediately while the crostini are still crisp.
