Flank steak is a lean, flavorful cut that cooks quickly on high heat. In Bobby Flay’s version, the steak is marinated to tenderize it and grilled to perfection before being topped with chimichurri sauce — a classic Argentinian condiment made from parsley, oregano, garlic, olive oil, and vinegar. The sauce adds freshness and tang, balancing the rich, smoky steak beautifully.
1 ½ lbs flank steak
3 tablespoons olive oil
2 tablespoons red wine vinegar
3 garlic cloves, minced
1 teaspoon smoked paprika
1 teaspoon salt
½ teaspoon black pepper
1 cup fresh parsley, finely chopped
2 tablespoons fresh oregano, chopped (or 1 tablespoon dried)
3 garlic cloves, minced
½ teaspoon red pepper flakes (optional)
½ cup olive oil
2 tablespoons red wine vinegar
Juice of ½ lemon
Salt and pepper to taste
Prepare the marinade – In a bowl, whisk together olive oil, red wine vinegar, garlic, smoked paprika, salt, and black pepper.
Marinate the steak – Place the flank steak in a shallow dish or resealable bag. Pour the marinade over and refrigerate for at least 1 hour, or up to 8 hours for maximum flavor.
Preheat the grill – Heat the grill to medium-high and lightly oil the grates.
Grill the steak – Remove steak from marinade and pat dry. Grill for 4–5 minutes per side for medium-rare or until desired doneness.
Rest the steak – Transfer to a cutting board and let rest for 5–10 minutes to retain juices.
Make the chimichurri – In a bowl, combine parsley, oregano, garlic, red pepper flakes, olive oil, vinegar, lemon juice, salt, and pepper. Stir until well mixed.
Serve and garnish – Slice the steak thinly against the grain and drizzle generously with chimichurri sauce.
