Common Mistakes to Avoid
When preparing Marinated Grilled Flank Steak, avoiding common mistakes can make a significant difference in flavor and texture. Here are some pitfalls to watch out for:
-
Skipping the Marinade Time: Not allowing enough time for marinating can lead to bland steak. Aim for at least 8 hours for maximum flavor absorption.
-
Using High Heat Without Preheating: Cooking the steak on a grill that isn’t preheated can result in uneven cooking. Always preheat your grill to achieve those perfect grill marks.
-
Cutting Against the Grain Incorrectly: Slicing the meat against the grain is essential for tenderness. Take care to identify the direction of the grain and cut diagonally.
-
Neglecting to Let It Rest: Cutting into the steak immediately after grilling can cause juices to escape. Always let it rest for 5-10 minutes before slicing.
-
Overcooking the Steak: Cooking beyond medium rare can dry out flank steak. Use a meat thermometer to check doneness accurately.
-
Ignoring Seasoning After Cooking: Failing to season after grilling can result in a less flavorful steak. Always adjust salt and pepper according to taste before serving.
