When it comes to cooking a flank steak, one of the most common questions asked is “how long do you smoke a flank steak?” Smoking a flank steak is a great way to infuse it with flavor and create a tender and juicy end result.

However, getting the timing right can be tricky. So, let’s dive into the details.

Preparing Your Flank Steak

Before we get into smoking times, it’s important to prepare your flank steak properly. Start by marinating your steak for at least 30 minutes or up to 24 hours in the fridge.

This will help to tenderize the meat and infuse it with flavor. You can use any marinade you like, but a simple mixture of olive oil, garlic, salt, and pepper works well.

Once your flank steak has been marinated, remove it from the fridge and let it come to room temperature for about 30 minutes before smoking. This will help ensure even cooking.

Smoking Your Flank Steak

Now that your flank steak is ready for smoking, it’s time to talk about timing. The length of time you smoke your flank steak will depend on a few factors such as the size of your cut of meat and how hot your smoker is running.

As a general rule of thumb, plan on smoking your flank steak for about 1 hour at 225°F-250°F. However, keep in mind that this is just an estimate and you should use a meat thermometer to check the internal temperature of your steak as it cooks.

Internal Temperature

The internal temperature of your flank steak is what really matters when determining if it’s done or not. For medium-rare doneness (which is recommended for flank steaks), aim for an internal temperature of 135°F-145°F.

Use an instant-read meat thermometer to check this temperature in the thickest part of your steak. Be sure to insert the thermometer from the side, rather than from the top or bottom, to get an accurate reading.

Resting Your Flank Steak

Once your flank steak has reached the desired internal temperature, remove it from the smoker and let it rest for at least 10 minutes before slicing. This allows the juices to redistribute throughout the meat and will result in a more tender and flavorful end result.


So, how long do you smoke a flank steak? Plan on smoking it for about 1 hour at 225°F-250°F, but use a meat thermometer to check for doneness.

Aim for an internal temperature of 135°F-145°F for medium-rare doneness. Remember to let your steak rest before slicing and serving.

With these tips and tricks, you can create a perfectly smoked flank steak that will impress your friends and family at your next barbecue.
