The key to a well-cooked Flat Iron steak is selecting the right cut. Look for steaks that are bright red in color and have plenty of marbling — this indicates a higher fat content, which helps keep your steak tender and juicy. You should also look for steaks with an even thickness so that they cook evenly.

Step 2: Prepping The Steak

Once you have your steak, it’s time to prep it for cooking. First, pat the steak dry with paper towels and season both sides with salt and pepper.
