Grilling a delicious flank steak to perfection is an art that requires patience, precision, and expertise. However, one of the most common questions that people ask is, “How long does it take to grill flank steak medium?”

The answer to this question varies depending on several factors such as the thickness of the steak, the heat of the grill, and personal preference. In this article, we will discuss how long it takes to grill flank steak medium and some tips for ensuring a juicy and flavorful outcome.

What is Flank Steak?

Flank steak is a lean cut of beef that comes from the abdominal muscles of the cow. It is a popular choice for grilling due to its rich beefy flavor and tender texture when cooked correctly. However, it can be tough if not cooked correctly.

Preparing Flank Steak for Grilling

Before grilling flank steak, it’s essential to prepare it properly for optimal results. Begin by removing any excess fat from the meat using a sharp knife. Then use a meat mallet or a fork to tenderize the meat by piercing small holes all over its surface.

After tenderizing the meat, season it with your preferred spices or marinade. Popular seasonings for flank steak include garlic powder, paprika, salt, and pepper. Let it sit in the marinade or seasoning for at least 30 minutes before grilling.

How Long Does It Take to Grill Flank Steak Medium?

The time it takes to grill flank steak medium varies based on different factors such as:

  • The thickness of your steak
  • The heat level of your grill
  • Your preferred level of doneness (medium-rare or medium)

A general rule of thumb for grilling flank steak is four minutes per side over high heat for medium-rare and five minutes per side for medium. For a one-inch-thick flank steak, cook it on high heat for about 4-5 minutes per side for medium-rare and 5-6 minutes per side for medium.

However, the best way to determine whether your steak is cooked to your preferred level of doneness is by using a meat thermometer. Insert the thermometer into the thickest part of the steak, and if it reads 135°F (57°C), it’s medium-rare, and if it reads 145°F (63°C), it’s medium.

Tips for Grilling Flank Steak

Here are some tips to ensure that you grill a juicy and flavorful flank steak:

  • Let the steak rest: Once you have finished grilling your flank steak, let it rest for at least five minutes before slicing. This allows the juices to redistribute throughout the meat, making it juicier.
  • Use high heat: Flank steak requires high heat to caramelize its surface while keeping its interior tender and juicy.
  • Don’t overcook: Overcooking flank steak can make it tough and Chewy. It’s essential to take care not to overcook it.


Grilling a delicious flank steak to perfection requires attention to detail and patience. However, with proper seasoning, grilling time, and temperature control, you can achieve an excellent result every time.

Keep in mind that personal preference plays a significant role in determining how long you should grill your flank steak. Follow these tips, use a meat thermometer when necessary, and enjoy your juicy and flavorful grilled flank steak!
