Make the Marinade
- In a medium bowl, whisk together soy sauce, Worcestershire, olive oil, balsamic vinegar, Dijon mustard, minced garlic, rosemary, and black pepper until well combined. The mustard helps emulsify the mixture so it coats the steak evenly.
- Place steak in a gallon zip-top bag or shallow dish. Pour marinade over, seal or cover, and turn to coat completely. Refrigerate for at least 2 hours or up to 8 hours. Do not exceed 12 hours or the acid will start to break down the meat texture.
- Remove steak from refrigerator 30 minutes before cooking to take the chill off. Lift steak from marinade and let excess drip off. Pat surface lightly with paper towels for better sear. Discard used marinade.
- Grill over high heat or sear in a hot cast-iron skillet for 4-5 minutes per side for medium-rare, depending on thickness. The sugars in the marinade will create a beautiful dark crust. Rest 5-10 minutes before slicing against the grain.
Notes
For maximum tenderness on flank or skirt steak, slice thinly against the grain at a 45-degree angle. This marinade also works beautifully on chicken thighs or pork chops. Make a double batch and freeze half with raw steak for an instant meal prep solution.
