Ingredients

  • 1/2 cup extra virgin olive oil
  • 1/4 teaspoon smoked hot paprika
  • 2 cups lightly packed parsley leaves
  • 2 tablespoons fresh oregano leaves
  • 1/4 cup chopped red onion
  • 1 clove garlic
  • 1/4 teaspoon chili pepper flakes
  • 6 tablespoons red wine vinegar
  • 1 teaspoon coarse salt
  • 2 teaspoons olive oil
  • 1 1/2 pounds sirloin steak, 1 1/4 inches thick
  • Salt and freshly ground black pepper

Method

  • For Sauce: In a small skillet set over medium-high heat, heat oil and paprika until oil shimmers and paprika is fragrant, about 2 to 3 minutes.
  • Remove skillet from heat and let cool.
  • In the bowl of a food processor, combine parsley, oregano, red onion, garlic, and chili pepper flakes.
  • Pulse to chop.
  • Add vinegar and salt; pulse, and slowly drizzle in cooled oil with machine running.
  • Chop until sauce is emulsified and chunky.
  • For Steak: Heat the olive oil in a well-seasoned cast iron skillet over medium-high heat.
  • Season steak season well with salt and pepper.
  • Place steak in skillet on the fatty edge and cook until the fat has rendered into the pan and the edge is brown, about 3 minutes.
  • Turn and cook the other edge for 2 minutes.
  • Now cook the wide sides of the steak until nicely browned, about 6 minutes per side for medium-rare.
  • Remove from skillet and let rest 10 minutes.
  • Slice steak thinly, and serve with Chimichurri sauce.
  • Note: Although the chimichurri can be refrigerated for a day, the sauce is best made just before eating, as the acid in the marinate will turn the parsley army-green if it sits for more than a few hours.
