Flank steak, known for its rich beefy flavor and distinctive grain, responds beautifully to smoking, which infuses it with deep, complex aromas while gently breaking down its fibrous texture. However, because it’s a relatively thin and lean cut, timing is crucial—too little smoke and it may be tough; too long and it risks drying out. This delicate balance makes the question of “how long to smoke flank steak” an essential consideration for anyone looking to elevate their barbecue game.

In the following sections, we’ll explore the factors that influence smoking time, the ideal temperature ranges, and tips to ensure your flank steak comes out juicy, tender, and packed with smoky goodness. Whether you’re aiming for a quick smoke or a slow, low-and-slow cook, understanding these principles will help you master the technique and impress at your next cookout.

Ideal Smoking Times and Temperatures for Flank Steak

Smoking flank steak requires careful attention to both temperature and timing to achieve the desired tenderness and flavor. Because flank steak is a lean cut with long muscle fibers, it benefits from slow, low-temperature smoking that allows the connective tissue to break down without drying out the meat.

Typically, the smoking temperature ranges between 225°F to 250°F (107°C to 121°C). At these temperatures, the flank steak will cook evenly and develop a rich smoky flavor while maintaining juiciness. The total smoking time can vary depending on the thickness of the steak and the exact smoker temperature but generally falls within 1.5 to 3 hours.
