Common Mistakes to Avoid
Preparing the perfect Marinated Grilled Flank Steak can be tricky. Here are some common mistakes to watch out for:
- Skipping the Marinade Time: Not allowing enough time for the steak to marinate can result in bland flavors. Aim for at least 8 hours of marinating for optimal taste.
- Overcooking the Steak: Cooking flank steak too long can make it tough. Use an instant-read meat thermometer to achieve your desired doneness, ideally around 130F/55C for medium rare.
- Cutting Against the Grain: Slicing the meat in the wrong direction can lead to chewy pieces. Always cut against the grain to ensure tender bites.
- Not Preheating the Grill: Failing to preheat your grill can cause uneven cooking. Make sure your grill is hot before placing the steak on it, ideally at 450-500F or 230-260C.
- Ignoring Resting Time: Cutting into the steak immediately after cooking can let all the juices escape. Allow it to rest covered with foil for 5-10 minutes before slicing.
Refrigerator Storage
- Store leftovers in an airtight container.
- Consume within 3-4 days for best quality.
Freezing Marinated Grilled Flank Steak
- Wrap tightly in plastic wrap or aluminum foil before placing in a freezer-safe bag.

Reheating Marinated Grilled Flank Steak
- Oven: Preheat to 250F/120C and cover the steak with foil. Heat until warmed through, about 15-20 minutes.
