How to Make Marinated Grilled Flank Steak
Step 1: Prepare the Marinade
Combine all marinade ingredients in a mixing bowl:
* In a bowl, mix together balsamic vinegar, fresh juice, Worcestershire sauce, garlic powder, black pepper, salt, and olive oil.
Step 2: Marinate the Steak
You want to let your steak soak in all those delicious flavors:
* Trim excess fat from the flank steak if necessary.
* Place the steak in a Ziploc bag, pour in the marinade, seal it tight, and refrigerate for at least 8 hours.
Step 3: Preheat Your Grill
Get your grill ready for cooking:
* Preheat your grill to high heat (450-500°F or 230-260°C).
* Allow your marinated flank steak to come to room temperature while the grill heats up.
Step 4: Cooking Time!
It’s time to grill your marinated flank steak to perfection:
1. Remove the steak from the marinade and let excess liquid drain off.
2. Place the steak on an angle across the grill grates; adjust heat if necessary.
3. Cook for about 3 minutes until grill marks appear, then rotate it at an opposite angle for another 3 minutes.
4. Flip over and cook on this side for about 4-5 minutes until reaching medium rare (130°F/55°C).
Step 5: Resting Time
Resting is key to juicy results:
* Once cooked, remove from grill, cover with foil, and let rest for 5-10 minutes before slicing.

Common Mistakes to Avoid
When preparing Marinated Grilled Flank Steak, it’s easy to make some common errors that can affect the final dish. Here’s how to avoid them.
-
Skipping the Marinade Time: Not allowing enough time for the steak to marinate can result in bland flavor. Aim for at least 8 hours, or overnight if possible.
-
Not Letting the Steak Rest: Cutting into the steak immediately after cooking can cause juices to escape, leading to dryness. Always let it rest for 5-10 minutes before slicing.
-
Using Too High of a Heat: Cooking on excessively high heat may char the outside without properly cooking the inside. Preheat your grill to a medium-high setting instead.
-
Cutting Against the Grain Incorrectly: Slicing against the grain helps keep the meat tender. Make sure you identify the grain direction before cutting.
-
Ignoring Temperature Checks: Not using a meat thermometer can lead to overcooking or undercooking. Aim for 130F/55C for medium rare to retain juiciness.
-
Not Trimming Fat Properly: Leaving too much fat can lead to flare-ups and uneven cooking. Trim excess fat but leave some for flavor.
