Scale
For the Steak and Marinade
- 1 lb (450g) flank steak, cut into strips
- 1/4 cup (60ml) soy sauce (or coconut amino)
- 1 tablespoon olive oil
- 1 tablespoon Sriracha (or hot sauce)
- Fresh cracked black pepper, to taste
For the Butter Sauce
- 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
- 1/2 cup beef stock (or water)
- 1 tablespoon lemon juice
- Salt and fresh cracked pepper, to taste
For Garnish and Serving
- Fresh chopped parsley, for garnish
Instructions
- Marinate the Steak: In a bowl, combine soy sauce, olive oil, Sriracha, and black pepper. Add the steak strips, ensuring they are fully submerged, and let marinate for at least 30 minutes in the refrigerator.
- Sear the Steak: Melt 1 tablespoon of butter in a skillet over medium-high heat. Remove steak from marinade, season with salt and pepper, then sear quickly for 1–2 minutes per side until browned. Transfer to a covered plate and set aside.
- Prepare the Sauce Base: Lower heat to medium. In the same skillet, add remaining butter and cook shallot and garlic, stirring occasionally until soft and fragrant, about 2 minutes. Stir in thyme, chives, chili flakes, lemon juice, Dijon mustard, and beef stock, scraping up browned bits with a wooden spoon. Cook until the liquid reduces by half, approximately 5 minutes.
- Finish the Sauce: Swirl in butter to create a rich sauce. Adjust seasoning with salt and pepper.
- Reheat the Steak: Return the steak to the skillet, reheat briefly, then garnish with chopped parsley and serve immediately alongside your favorite side dishes.
Notes
- Make sure not to overcook the steak to keep it tender; 1–2 minutes searing per side is ideal for medium-rare.
- Marinating longer than 30 minutes can enhance flavor but isn’t necessary for great taste.
- Use fresh herbs for the best flavor in the sauce.
- For a richer sauce, add a splash of heavy cream or a teaspoon of Worcestershire sauce.
