Ingredients

  • 8 ounces filet mignon
  • 1 teaspoon Kosher salt
  • Freshly ground black pepper
  • 1 tablespoon neutral oil such as avocado or vegetable oil
  • ½ baguette sliced into ½ inch slices
  • 3 ounces Boursin cheese about half of the package
  • 2 tablespoons finely chopped parsley
  • 2 tablespoons finely chopped chives
  • 1 garlic clove grated or finely chopped
  • ¼ cup olive oil
  • Flakey sea salt for garnish

Instructions

  • Bring the steak to room temperature and pat dry with paper towels. Season the filet mignon with salt and pepper, gently patting it down so the seasonings stick to the steak.
  • Place a medium sized cast iron skillet to high heat and pour neutral oil in Once hot, sear the steaks for 4-5 minutes on the first side, then flip over and continue cooking for another 3-4 minutes, until the steaks form a deep crust. Reduce the time by 1-2 minutes for a thinner filet.
  • Once the steaks are seared, remove them to a plate and let the steaks rest for at least 5 minutes before slicing. Once ready, slice the steak into thin slices against the grain.
  • Toast the sliced baguette in a dry skillet until golden brown. You can also toast the bread slices in the oven at 350 degrees Fahrenheit for 5-6 minutes until golden brown.
  • For the herb oil, add the chopped parsley, chives, grated garlic and olive oil to a bowl and stir to combine.
  • To assemble, spread a thin layer of Boursin cheese into each crostini and top with a slice of filet and a drizzle of herb oil. Garnish with flakey sea salt over the top and serve immediately.

Notes

    • Dry the Meat: Dry the steaks well with paper towels, this will make sure the steaks get a good sear.
    • Rest the Filet: Once the steaks are done cooking, let the meat rest for at least 5 minutes before slicing.
    • Bring the Boursin Cheese to Room Temperature: Leave the boursin cheese on the counter at room temperature for at last 30 minutes. This will make the cheese creamier and easier to spread onto the crostini.
    • Toast or Grill the Bread: Toast the sliced baguette in a dry skillet until golden brown. You can also toast the bread slices in the oven at 350 degrees Fahrenheit for 5-6 minutes until golden brown.
