A thick-cut prime Argentinian sirloin steak seared over hardwood charcoal on the parrillero, rested to juicy perfection and served with vibrant herb and garlic chimichurri.
Whisk minced parsley, garlic, olive oil, red wine vinegar, dried oregano, ají molido, salt, and pepper in a jar; let steep overnight at room temperature for flavours to develop.
Prepare an open wood/charcoal parrillero with embers pushed below the V-shaped iron grate; heat grate to medium-high.
Season thick steaks generously with coarse parrillera salt 15 minutes before cooking.
Place steaks on the preheated grate at a 45-degree angle; sear undisturbed for 5-6 minutes until deep golden grill marks form; rotate 90 degrees for crosshatch marks, then flip and cook for 5 minutes for authentic jugoso medium-rare (54°C).
Rest steaks on a warm wooden cutting board for 8 minutes to allow internal juices to settle.
Slice thick and spoon fragrant chimichurri sauce over the top; serve with grilled provoleta and crusty bread.
