Ingredients

Scale
  • One 1lb (450g) flank steak, cut into strips
  • 1+2 tablespoons unsalted butter, divided
  • 1 small shallot, finely chopped
  • 3 garlic cloves, minced
  • Pinch of red chili pepper flakes, to taste
  • 1 tablespoon Dijon mustard
  • 3 teaspoons minced fresh thyme
  • 1 tablespoon finely minced chives
  • ½ cup beef stock (or water)
  • 1 tablespoon lemon juice
  • Salt and fresh cracked pepper, to taste
  • Fresh chopped parsley, for garnish

For the marinade:

  • 1/4 cup (60ml) soy sauce (or coconut amino for paleo and gluten-free)
  • 1 tablespoon olive oil
  • 1 tablespoon Sriracha (or any hot sauce you like)
  • Fresh cracked black pepper, to taste

Instructions

  1. Combine soy sauce, olive oil, Sriracha, and pepper in a bowl to create marinade. Add steak strips and marinate for at least 30 minutes.
  2. Heat a skillet over medium-high heat. Add 1 tablespoon butter. Remove steak from marinade, pat dry, and sear for 1-2 minutes per side. Transfer to a plate.
  3. Reduce heat to medium. Cook shallot and garlic in the same skillet for 2 minutes until softened.
  4. Add thyme, chives, chili flakes, lemon juice, mustard, and beef stock. Scrape up browned bits with a wooden spoon.
  5. Simmer until liquid is reduced by half, about 5 minutes.
  6. Add remaining 2 tablespoons butter, swirling to melt. Season with salt and pepper.
  7. Return steak to the pan briefly to reheat.
  8. Garnish with parsley before serving.
