Grilled Marinated Flank Steak – learn how to grill flank steak (+ easy flank steak marinade included). Serve with chimichurri sauce!



Flank Steak:

Flank Steak Marinade:

  • 2 tablespoons extra virgin olive oil
  • 1 tablespoon lime juice
  • 2 tablespoons soy sauce
  • 1/2 teaspoons sesame oil
  • 2 teaspoons garlic, minced
  • 1 teaspoon worcestershire sauce
  • 1/4 teaspoon dried oregano
  • 1/4 teaspoon garlic powder
  • 1/4 teaspoon dried rosemary, crushed
  • pinch of salt
  • pinch of ground black pepper


  1. Place flank steak in a large bowl, reusable silicone bag or freezer bag and let come to room temperature.
  2. In a small bowl combine olive oil, lime juice, soy sauce, sesame oil, garlic, worcestershire sauce, oregano, garlic powder, dried rosemary, salt and pepper. Whisk to combine. 
  3. Pour marinade over the steak and ensure it is fully covered. Let marinate a minimum of 30 minutes.
  4. Ensure grill has clean grates and bring to medium/high heat (450-500 degrees F). 
  5. Remove steaks from marinade (let any excess marinade fall off) and place over direct heat. Close grill. 
  6. Sear on grill 3-5 minutes per side for medium rare or until the center of the thickest part of the steak reaches 130 degrees F using an internal meat thermometer – or let cook until desired level of doneness.
  7. Remove from grill and let rest for 10 minutes.
  8. Place on a cutting board and cut into strips (cut against the grain).


  • Gluten-free: coconut aminos or tamari a great soy sauce substitutes.
  • up the spice: feel free to add a little dash of red pepper flakes to the marinade!
