Instructions

How to Make Savory Marinated Flank Steak Sandwich

  • In a bowl, whisk together canola oil, lemon juice, soy sauce, Worcestershire sauce, Dijon mustard, brown sugar, black pepper, salt, and minced garlic until smooth and fully combined.
  • Place the flank steak in a resealable bag, pour the marinade over, seal it tight, and refrigerate for 4 to 8 hours.
  • In a small bowl, mix together softened butter, minced garlic, chives, thyme, parsley, and salt until well combined.
  • Ignite all burners and preheat your grill for about 5 minutes.
  • Brush the onions lightly with oil and add them to the grill alongside the flank steak. Cook both for approximately 5 minutes per side until charred and tender.
  • After grilling, let the steak rest for 5 minutes before slicing against the grain.
  • Spread garlic-herb butter on the cut sides of the ciabatta and grill until golden brown, about 1 to 2 minutes.
  • Layer the sliced steak on the grilled ciabatta, add grilled onions and cheese, cover it, and let the cheese melt.
  • Top with arugula, close the sandwich, and serve immediately.

Notes

Optional: Try adding pickled jalapeños for a spicy kick!
