Description

A simple and delicious Cast Iron Flank Steak Recipe + marinade that is perfect for salads, fajitas and rice bowls!


Ingredients

Scale

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 kosher salt
  • pinch of ground black pepper

Flank Steak:

  • 1 1/2 pounds flank steak
  • 1 tablespoon extra virgin olive oil
  • 1 batch chimichurri sauce for serving

Instructions

  1. Marinate Steak: Combine Flank Steak Marinade ingredients in a small bowl; whisk to combine. Pat flank steak dry with a clean paper towel. Season with salt and pepper – press into the meat. Place steak in a reusable silicone bag or glass container. Pour marinade over top and ensure the steak is fully coated.  Let marinate at least 30 minutes. 
  2. Cook Steak: Bring a large cast iron skillet to medium-high heat. Add oil, swirl to coat the pan. Remove flank steak from the marinade letting excess liquid drip off; discard marinade. Place steak in the hot pan and sear 4-5 minutes per side and then 1-2 minutes per side until the internal temperature towards the thickest part of the steak reaches 130-135 degrees F. for a medium-rare finish (use an internal meat thermometer for accuracy) – during the cooking process turn down the heat, as-needed, if your skillet really gets hot and/or add a little extra oil if the pan is dry – to avoid burning. 
  3. Rest + Serve: Remove from skillet and place on a cutting board to rest 10 minutes. Slice against the grain and serve – we love serving it with this Homemade Chimichurri Sauce or in these Steak Fajita Bowls
