Grilling a flank steak on a Big Green Egg may seem daunting at first, but with the right techniques and tools, it can be a delicious and easy meal to prepare. Here are some steps to help you grill a perfect flank steak on your Big Green Egg.

Step 1: Prepare the Steak

The first thing you need to do is prepare your flank steak for the grill. Start by seasoning both sides of the steak with salt, pepper, and any other seasonings you like. You can also marinate the steak overnight in your favorite marinade for extra flavor.

Step 2: Preheat Your Big Green Egg

Before you start grilling, preheat your Big Green Egg to around 500°F. This will ensure that your grill is hot enough to sear the steak and lock in all those delicious juices.

Step 3: Sear Both Sides

Once your grill is hot enough, place the flank steak onto the grates and sear each side for about 3-5 minutes or until it develops a nice crust. This helps to lock in all those juices and create that beautiful charred exterior.


For best results, don’t move or flip the steak too often while it’s searing. This ensures that each side gets evenly cooked and develops that perfect crust.

Step 4: Lower Temperature

After searing both sides of the steak, lower the temperature of your grill to around 350°F. This will allow you to cook the inside of the steak without burning the outside.

Step 5: Cook Until Desired Doneness

Cook your flank steak on each side for about 4-5 minutes or until it reaches your desired level of doneness. Use a meat thermometer to check the internal temperature of the steak. For medium-rare, aim for a temperature of around 135°F.


Don’t forget to let your steak rest for a few minutes before slicing and serving. This allows the juices to redistribute back into the meat, resulting in a more tender and flavorful steak.

In Conclusion

Grilling a flank steak on a Big Green Egg is all about getting that perfect sear on the outside while still keeping the inside juicy and tender. With these simple steps, you can achieve a delicious and perfectly cooked flank steak every time. So fire up your Big Green Egg and get grilling!
