Mix all the marinade ingredients together for the steak and place the marinade and steak in a ziplock bag for up to 2 hours
Heat your BBQ to 300c and the oven to 180c
Drizzle the tomatoes in oil and salt – set aside
Clean the potatoes and chop them into 1cm cubes and par boil them for 3-4 minutes *see tips*
Finely dice the rosemary for the potatoes
Grill the steak on your BBQ for 10 – 12 minutes @ 300c or until internal temperature is 52-54c for medium-rare. The higher temperature will give you a nice crust/sear on the steak *see tips*
Allow the steak to rest for 10 minutes
As the steak is resting roast the tomatoes for 10-12 minutes @ 180c in the oven
Fry the potatoes on high heat in olive oil for 10 minutes/ until golden brown, add the rosemary, butter & garlic at the end and toss to combine
Slice your steak and serve with vine tomatoes, potatoes and either a jus, mustard or whatever sauce you enjoy with your steak
Notes
Tips/Tricks
this recipe calls for the steak to be marinated minimum of 2 hours – my advice is to do so in the morning before work or whatever daily activities you will be doing so that come dinner time it’s quick and easy to make!
if you don’t have a BBQ then you can grill the steak on high for 2-3 minutes per side and then finish in the oven for 8-10 minutes or until internal temperature is 52-54c for medium-rare
you can prepare the potatoes in advance - just leave them in a bowl of ice-cold water in the fridge to stop them from oxidising and going brown
if you don’t parboil the potatoes you will need to fry them for about 15 minutes instead of 10 to ensure they are cooked through
resting the meat is just as important as cooking it to the right temperature – if you cut the meat to soon then the juices won’t have time to re-distribute and you will be left with a pool of red and an overcooked piece of meat
