In a large plastic or glass bowl, whisk together ¼ cup of olive oil, ¼ cup of Worcestershire sauce, 2 Tbsp of soy sauce, 2 Tbsp of red wine vinegar, 2 Tbsp of brown sugar, 1 Tbsp of dijon mustard, 1 tsp of garlic powder, ½ tsp of smoked paprika, ½ tsp of salt, and ¼ tsp of freshly ground black pepper.
Place the steaks in the marinade, ensuring they are fully coated.
Cover the bowl and refrigerate for at least 30 minutes, or up to 4 hours for deeper flavour penetration.
Preheat your barbecue hotplate or grill to medium-high heat.
Once hot, oil the grill grates to prevent sticking.
Remove the steaks from the marinade and pat them dry with paper towels.
Discard any remaining marinade.
Cook the steaks for 4-5 minutes per side, or until they reach your desired doneness.
For a medium-rare steak, an internal temperature of 57°C (135°F) is recommended.
Once cooked, remove the steaks from the grill and let them rest for 5-10 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavourful steak.
