Ingredients

Instructions

  1. Heat butter in a large skillet over medium heat. Add sliced onion and sauté for 5 minutes or until starting to soften. Add a pinch of salt, reduce the heat to low, and continue cooking, stirring them every few minutes to prevent them from sticking and colouring too much in any one place, until dark-coloured, about 10 to 15 minutes.
  2. Preheat a grill, grill pan or cast-iron skillet to medium-high heat, and add olive oil if using a pan. Place the steak on a cutting board and season generously with salt and pepper on both sides.
  3. Once the grill or skillet is hot, add steak to the pan and cook until golden brown and slightly charred, 4 to 5 minutes. Turn the steak over and continue to grill 3 to 5 minutes for medium-rare, 5 to 7 minutes for medium or 8 to 10 minutes for medium-well. For perfect cooking, it is ideal to use an instant-read thermometer to determine when your steak is cooked to your liking (125°F for rare, 130-135°F for medium-rare, 140°F for medium).  Once cooked, remove the steak from the pan and transfer it to a cutting board or plate, tent it with aluminum foil, and let the steak rest for at least 5 minutes before slicing.
  4. Optional: While the steak is resting, toast the bread or broil it in the oven.
  5. Once the steak has rested, place it on a cutting board and slice, against the grain, into thin strips.
  6. Lay the bread on a cutting board and spread the bottom slice of bread with mustard. Add slices of steak, a sprinkle of salt and pepper, brie cheese, caramelized onions, and arugula, and top with the second slice of bread spread with mayonnaise. The ingredients should make two sandwiches.
  7. The steak sandwiches can be served immediately or stored in the fridge wrapped in plastic wrap or in an airtight container for 24 hours.
