How to Make Argentinian Grilled Flank Steak With Chimichurri Sauce

  1. Pat the flank steak dry with paper towels. This helps achieve a good sear.
  2. In a small bowl, combine all chimichurri ingredients. Mix well and set aside.
  3. Preheat grill to high heat (about 450°F).
  4. Season the flank steak generously with salt and pepper.
  5. Grill the steak for 4-5 minutes per side for medium-rare, or longer to your desired doneness. Use a meat thermometer to ensure accuracy (130-135°F for medium-rare).
  6. Remove the steak from the grill and let it rest for 10 minutes before slicing against the grain.
  7. Slice the steak thinly against the grain.
  8. Serve immediately, topped generously with chimichurri sauce.
