Pro Tips

  • Sear the steak on high heat to create a flavorful crust. This locks in juices, ensuring each bite is tender and juicy.
  • Caramelize onions slowly over low heat. Patience is key to developing their natural sweetness and achieving a deep golden color.
  • Let the steak rest before slicing. This allows the juices to redistribute, resulting in a more flavorful and moist sandwich.

Chef's Notes

  • Store caramelized onions in an airtight container in the fridge for up to a week. Reheat gently to preserve their sweet, rich flavor.
  • For a make-ahead option, marinate the steak overnight. This deepens the flavor and tenderizes the meat, making it even more succulent.
  • Use a crusty baguette to prevent the sandwich from becoming soggy. The firm texture holds up well against juicy steak and onions.
  • Substitute arugula with fresh spinach for a milder, less peppery taste. Both add a vibrant green freshness to the sandwich.
