If you’re a fan of grilled meats, then you’ve probably wondered how long different cuts of beef take on the grill. One such cut is flank steak, which is known for its robust flavor and versatility. However, cooking it to perfection can be a bit tricky, especially if you’re not sure about the right grilling time.

What is Flank Steak?
Before we dive into the cooking process, let’s first understand what flank steak is. It’s a long and flat cut of beef that comes from the abdominal muscles of the cow. It has a coarse texture and is often used in dishes like fajitas, stir-fries, and sandwiches.

Preparing Flank Steak for Grilling
To get started with grilling flank steak, you’ll need to prepare it properly. Begin by trimming off any excess fat or silver skin on the meat.

Next, use a sharp knife to score the surface of the meat diagonally across both sides. Make sure not to cut too deep as this can cause it to dry out while grilling.

After scoring the meat, season it generously with your favorite spices or marinade. You can use anything from simple salt and pepper to more complex blends like garlic powder, cumin, or paprika. Let the meat sit at room temperature for at least 30 minutes before placing it on the grill.

Direct Heat Method

The most common method for grilling flank steak is using direct heat. This involves placing the meat directly over hot coals or flames and cooking it until desired doneness. Here’s a general guideline for cooking times based on thickness:

  • ½ inch thick – 2-3 minutes per side (rare)
  • ¾ inch thick – 3-4 minutes per side (medium-rare)
  • 1 inch thick – 4-5 minutes per side (medium)

Note that these are just estimates and can vary based on your grill’s temperature and the meat’s thickness. To ensure that your steak is cooked to perfection, use a meat thermometer to check its internal temperature. For rare, the thermometer should read about 125°F, while medium-rare is around 135°F.

Indirect Heat Method

Alternatively, you can also use indirect heat to grill flank steak. This involves placing the meat away from the direct heat source and letting it cook slowly. Here’s how to do it:

  • Preheat your grill to medium-high heat.
  • Place the seasoned flank steak on the cooler side of the grill.
  • Cover the grill and let cook for about 15-20 minutes per side.

Again, it’s important to check the internal temperature of the meat with a thermometer to ensure it’s cooked to your liking.


In summary, grilling flank steak requires some preparation and attention to detail. Whether you’re using direct or indirect heat, make sure to season it well and monitor its cooking time closely. With practice, you’ll be able to achieve perfectly grilled flank steak every time!
