  • 2 sirloin steaks taken out of the fridge for at least 20 minutes to come up to room temperature
  • 1 big handful of fresh basil
  • A big handful of fresh parsley
  • 1 big handful of fresh mint
  • Half a lemon juiced and the whole lemon zested
  • Salt and pepper or seasoning
  • 5 tablespoons of olive oil
  • Grape seed oil


  1. Get your basil, parsley, mint, lemon juice, lemon zest, and a pinch of salt and pepper in a blender. Blitz until you have a sauce that is nearly pureed, but still has some texture. If you don't have a blender, just chop the herbs and garlic really fine then mix in a bowl, or grind in a pestle mortar. Once the sauce is done set it aside.
  2. Make sure the steaks are patted dry. Season them well on both sides with salt and pepper then lightly coat the steaks in grape-seed oil.
  3. Pre-heat a griddle pan on high heat for a few minutes, get it really nice and hot before you start grilling the steak (make sure you turn your kitchen fans on).
  4. Once the pan is smoking hot, carefully lay your steaks down in the griddle pan. My steak was around 1 inch thick and I cooked them for about 4½ minutes on each side for medium rare.
  5. Just before you remove your steaks from the pan, pick your steak up with a pair of tongs. Then hold the steak fat side down and just spend half a minute searing that fat.
  6. Transfer the steak on a board or warm plate and let them rest for a few minutes. You can serve the steak whole, or slice it like I did, but make sure you don't slice it too thin. Spoon some of the Chimichurri sauce on top before you serve.

Recipe Notes

  • Make sure that steak is at room temperature before cooking it. Can't stress that enough. 
  • Make sure the pan is nice and hot before adding your steak. 
  • Make sure the steak is seasoned well.
