Grilling a flank steak can be a delicious and satisfying meal for any occasion. However, the question remains – how long should you grill a flank steak? The answer depends on several factors, including the thickness of the steak, the temperature of your grill, and your desired level of doneness.

Factors to Consider

Before you start grilling your flank steak, it’s important to consider its thickness. A thicker steak will take longer to cook than a thinner one. Additionally, if your steak is cold from being refrigerated, it will take longer to cook than one that has been sitting at room temperature for a while.

The temperature of your grill is also an important factor to consider. If your grill is too hot, you risk burning the outside of the steak while leaving the inside undercooked. On the other hand, if your grill is not hot enough, the steak may take too long to cook and become tough.

Finally, determining your desired level of doneness is crucial in determining how long you should grill your flank steak. Whether you prefer rare, medium-rare or well-done will impact how long you need to keep the meat on the grill.

Grilling Times

To achieve a rare flank steak (internal temperature of 125°F), you should grill it for approximately 4-6 minutes per side for a total grilling time of 8-12 minutes.

For medium-rare (130°F), grill for 6-7 minutes per side or 12-14 minutes total.

For medium (135°F), aim for 7-8 minutes per side or around 14-16 minutes total.

If you prefer well-done (150°F), grill for around 10-11 minutes per side or approximately 20-22 minutes in total.

Remember that these are just guidelines and actual cooking times may vary depending on various factors such as thickness and temperature of the steak.

Tips for Grilling Flank Steak

– Make sure to preheat your grill and oil the grates before placing the steak on it.

– To achieve optimal flavor, season both sides of the steak with salt and pepper before grilling.

– Avoid using a fork to flip the steak as it can puncture the meat and cause juices to escape. Instead, use tongs or a spatula.

– Let the steak rest for a few minutes after grilling to allow the juices to redistribute throughout the meat.


In conclusion, how long you should grill your flank steak depends on several factors such as thickness, grill temperature, and desired level of doneness. While there are guidelines for cooking times, it’s important to remember that actual cooking times may vary. By following these tips and guidelines, you can achieve a perfectly grilled flank steak that is juicy, flavorful, and cooked to your liking.
