Cilantro Lime Marinated Flank Steak – Flavorful & Low Carb

Cilantro Lime Marinated Flank Steak

I personally feel like flank steak is a highly underappreciated cut of beef. It is considerably less expensive per pound than many other steaks, it cooks a lot faster than thicker pieces of meat, and it is great for so many things from fajitas, salads, sandwiches and mostly as a vehicle for a delicious marinade. This Cilantro Lime Marinated Flank Steak is super easy to make, great to throw on the grill and serve to guests, low carb (only 1 net carb/serving!) and LOADED with flavor. Try it out for yourself and see!

Tips for making my Cilantro Lime Marinated Flank Steak:

  • Don’t forget to score your flank steak. If you aren’t sure how to do this, it’s pretty simple. Make shallow cuts in two directions all across your steak to create a diamond pattern. This will severe the long fibers in your steak which will leave you with a more tender piece of meat. Your marinade will also be able to seep into those cuts resulting in even more flavor.
  • If you have time, allow it to marinate for a full 24 hours. You will be glad you did when you bite into ultra tender and flavorful steak.
  • When slicing flank steak, ALWAYS slice against the grain. Cutting against the grain gives you the most tender slices of meat.
  • Don’t rush and immediately cut into your steak. Allow it to rest for 10 minutes first. Allow your meat to rest gives the juices a chance to redistribute.
