Pan-Seared Flank Steak with Chimichurri Sauce. Chimichurri sauce is a very popular traditional Argentinian sauce, widely used with grilled steak, chicken and other meats.
Place all ingredients for the sauce in the food processor and blend for about 4 minutes until you get pesto-like sauce. Using spatula, transfer sauce into a bowl.
Mix all spices together in a small bowl. Rub spices on both sides of flank steak, scatter chopped garlic over steak.
Heat a large skillet on high heat until very hot, add 2 tablespoons olive oil (it should sizzle). Add flank steak (with spices and garlic) and sear it on high heat about 4 minutes on one side. Flip it over, add 2 more tablespoons of olive oil, and sear 4 minutes on another side.
Cover the skillet with the lid – let the flank steak rest, covered, for about 5 or 8 minutes.
Transfer cooked flank steak onto the large platter and slice it into thin strips, against the grain.
Place strips of flank steak in the middle of each plate, top with a spoonful of Chimichurri sauce.
