Flank steak is one of the most underrated meats and makes an absolutely amazing steak. If cooked properly it will be moist, tender, and delicious.
When you are picking out your flank steak at the store, avoid the small ones that are only about a half pound to one pound because these will cook too fast and not become as juicy. They also might not be as tender, and won’t feed as big of a crowd.
Flank Steak Over Charcoal

Cooked flank steak in the Pit Barrel Cooker is tender and absolutely delicious.
Ingredients
- 1 or 2 Flank Steaks (Get the bigger ones that are at least 2 pounds or more in size.
- Seasoning - I used SPG (Salt, pepper and garlic). Salt and Pepper alone will also work well.
- Yellow Mustard
Instructions
- Prepare your Pit Barrel Cooker by lighting your charcoal according to the manufactures instructions.
- Rub yellow mustard all over the flank steak as a sticking agent. If you prefer olive oil will also work as a substitute for yellow mustard.
- Season the flank steak with the seasoning of your choice. SPG, also known as Salt, Pepper, and Garlic is a great compliment to this piece of meat. You can add other seasonings as well, or simply just use salt and pepper.
- Allow the flank to steak for about 15 minutes after adding seasoning to come partially up to room temperature. This is great to do while waiting for the Pit Barrel Cooker charcoal to get ready.
- Once your PBC is lit and heated, place a hook on one end of the flank steaks on the rod and close the lid.
- Cook to your desired internal temperature (I recommend 125 degrees). About 25 to 30 minutes. Check it with a probe after 20 minutes.
- Remove from heat and let sit for 5 to 10 minutes.
- Cut against the grain and enjoy!
Elevation – Lighting Your Pit Barrel Cooker Properly
You need to set your bottom vent to the proper elevation for your location. First, determine how far above sea level you are at your location. A simple Google search will help you determine this.
Then sit your vent according to shown below:
- 0-2000 feet the vent needs to be about 1/4 of the way open.
- 2000-5000 feet the vent needs to be about 1/2 of the way open.
- 5000-8000 feet the vent needs to be about 3/4 of the way open.
- Anything above 8000 feet leaves it all the way open.
By setting your vent to the settings above, you will ensure that your PBC is cooking at the proper temperature throughout the entire cooking process without worrying about it getting too hot, or not hot enough.
