Grilling a flank steak is a popular choice for many meat lovers, especially during the summer months. The flank steak is known for its rich flavor and juicy texture, making it a perfect choice for grilling.

However, cooking it to the right temperature can be a challenge. In this article, we will discuss how long it takes to grill a flank steak medium and tips to ensure that your steak is cooked to perfection.

Choosing the Right Flank Steak

Before we dive into how long it takes to grill a flank steak medium, let’s talk about selecting the right cut of meat. When choosing a flank steak, look for one that is bright red with good marbling throughout. The marbling is important because it adds flavor and moisture to the meat.

Preparing Your Flank Steak

Once you have selected your flank steak, it’s time to prepare it for grilling. Start by trimming away any excess fat from the edges of the steak.

Then, score the surface of the meat with shallow cuts about 1/4 inch apart on both sides. This will help tenderize the meat and allow marinades or seasonings to penetrate more deeply.

Marinades and Seasonings

If you choose to use marinades or seasonings on your flank steak, be sure not to overdo it. A simple mixture of olive oil, garlic, salt, and pepper can go a long way in enhancing the natural flavor of the meat. Let your steak marinate for at least 30 minutes before grilling.

Grilling Your Flank Steak Medium

Now comes the fun part – grilling your flank steak! Preheat your grill on high heat for 10-15 minutes before placing your steak on it.

Once you’ve placed your flank steak on the grill, sear each side for 3-4 minutes. This will help lock in the juices and create a nice crust on the outside of the meat.

After your steak has been seared, reduce the heat to medium and continue to grill for an additional 6-8 minutes. This should bring your flank steak to a medium level of doneness.

To ensure that your steak is cooked to perfection, use a meat thermometer to check the internal temperature. A medium flank steak should register at 145°F.

Letting Your Flank Steak Rest

Once you have removed your flank steak from the grill, resist the urge to cut into it right away. Instead, let it rest for 5-10 minutes before slicing into it. This will allow the juices to redistribute throughout the meat, resulting in a juicier and more flavorful steak.


Grilling a flank steak medium is all about timing and technique. By following these simple tips and tricks, you can achieve a perfectly grilled flank steak every time.

Remember to choose a quality cut of meat, prepare it properly, grill it with care, and let it rest before serving. With these steps in mind, you’ll be able to enjoy a delicious and juicy flank steak any day of the week!
