This is just a summary, so keep scrolling to find the full Smoked Flank Steak Recipe.

  • Flank Steak – it can be a little harder to locate, so if you can’t find it at your local grocery, be sure to ask the butcher. They can likely find one for you.

Marinade Ingredients

  • Olive Oil – The flavor combination dissolves better in olive oil and the oil will coat the surface of the meat and keep it there, rather than running off. Oil is often the first ingredient in a marinade.
  • Worcestershire Sauce – Adding tangy, sweet, and salty notes all in one sauce, Worcestershire may be difficult to pronounce, but it is an awesome addition to this marinade.
  • Apple Cider Vinegar – Essential to binding the sauce, this vinegar also adds some acidity and tartness.
  • Limes – You’ll use both the juice and the zest, so don’t work too quickly and forget to use the whole lime!
  • Brown Sugar – Cuts some of the tartness with some sweetness.
  • Dijon Mustard – Adds great flavor and helps bind a sauce.
  • Garlic – Helps create the base of almost any sauce, the flavor goes well with almost all other flavors.
  • Fresh Ground Pepper – Draw out the best of all the flavors and give your sauce a little kick.
  • Red Pepper Flakes – Give your sauce an even bigger kick with red pepper flakes!

How to Smoke Flank Steak on a Traeger (or any other smoker)

Using a whisk, mix all the marinade ingredients together in a small bowl. Grab a resealable bag and put the flank steak inside. Then pour the marinade over it. Seal the bag and place it in the refrigerator for anywhere from 30 minutes to 8 hours, depending on how much time you have and how much flavor you want. 

When you’re ready to smoke your now marinated flank steak, preheat your smoker and place the flank steak directly onto the grates. When it’s done, allow the steak to rest then slice it into thin strips to serve it.

How Do I Know When My Flank Steak is Done?

The best way to know when your flank steak is perfectly smoked is to check the internal temperature. If you are someone who uses their smoker regularly (or wants to start), investing in a leave-in meat thermometer won’t be a bad investment at all. But any meat thermometer will work.

What temp do you smoke flank steak?

The flank steak will be in the smoker, cooking at 225 degrees for around an hour and a half and up to two hours. When the internal temperature of your steak reaches 130-135 degrees, your steak is perfectly cooked.

You want to be careful not to overcook flank steak because it will become tougher, the more done it is. Medium rare is perfect. Plus, it will cook a little more while resting for 15 minutes and retaining its juices. Be sure not to cut into it until the steak has rested.
