  • Cast Iron Skillet


  • 2 small flank steaks 6-8 ounces each
  • Kosher oe sea salt to taste
  • Fresh Cracked Pepper
  • Avocado oil
  • 1/3 cup onion finely diced
  • 1/4 cup cilantro finely chopped
  • Your Favorite Salsa see link
  • Lime wedges


  • Before you start, bring the steaks out and let them come to room temperature for 30 minutes. Prep your garnishes and salsa.
  • Preheat cast iron skillet to heat just above medium until it begins to smoke lightly.
  • Drizzle oil onto steaks and then season to taste with salt and fresh cracked pepper.
  • When ready, transfer steaks to hot skillet. Sear for 3-4 minutes on the first side without moving the steak. Flip over and sear for 2 minutes, then rotate and sear for another 2 minutes or until internal temperature reads 128-132 degrees F. This will be medium rare,
  • If you like it more well done, flip over and cook for another few minutes until internal temperature reads 140 degrees F. Warm tortillas at this time.
  • Transfer steaks to wooden cutting board and let them rest for 5 minutes. When ready, slice thin and against the grain. Serve on warm tortillas. Garnish with onion, cilantro, salsa and lime!


Skirt, strip and chuck steaks can all be prepared this same way. The cast iron pan is the next best thing to grilling out! If the steak is thicker, one inch or more, you can finish cooking it in a 450 degree preheated oven until it reaches your desired internal temperature.
