Time and Temperature

Through loads of experimentation, we’ve found that cooking flank steak at 54C/129F for 2 hours is the perfect combo. Cooking the flank steak for two hours break down the connective tissue (collagen), which results in extremely tender, juicy beef. Also, cooking the steak at a temperature of 129F ensures that the beef is a beautiful medium rare with great texture. Just make sure you have a reliable sous vide that accurately regulates the temperature of the bath or your results may vary (check out the Anova or Joule).

By using a cast iron in this recipe, you’ll achieve a deep sear on the flank steak. Cast irons are also extremely handy for searing just about any and all sous vide meat. Lodge offers the best quality and price, which is why it is our favorite cast iron brand.
