Flank steak is a popular cut of beef known for its rich flavor and versatile cooking options. However, one question that often arises when cooking flank steak is how long it should be cooked for optimal results. In this article, we will explore the different factors that influence the cooking time of flank steak and provide some tips on how to ensure a perfectly cooked meal.

Factors Affecting Cooking Time

Thickness: One of the most significant factors affecting the cooking time of flank steak is its thickness. Thicker steaks will take longer to cook than thinner ones, so it’s essential to adjust the cooking time accordingly.

Cooking Method: The cooking method you choose can also affect the cooking time of flank steak. Grilling and broiling are typically faster methods than roasting or slow-cooking.

Internal Temperature: Another crucial factor that determines the cooking time of a flank steak is its internal temperature. Cooking times can vary based on your desired level of doneness, whether rare, medium-rare, medium, or well-done.

Cooking Times by Thickness

To help you determine how long to cook your flank steak based on its thickness, refer to these general guidelines:

  • For a 1/2 inch thick cut: Grill or broil for 3-4 minutes per side for medium-rare.
  • For a 3/4 inch thick cut: Grill or broil for 4-5 minutes per side for medium-rare.
  • For a 1-inch thick cut: Grill or broil for 6-7 minutes per side for medium-rare.

Tips for Perfectly Cooked Flank Steak

  • Remove the steak from the refrigerator at least 30 minutes before cooking to bring it to room temperature.
  • Preheat your grill, broiler, or oven before cooking.
  • Season your steak with salt, pepper, and other desired seasonings before cooking.
  • Use a meat thermometer to ensure that the internal temperature of the steak reaches your desired level of doneness. A rare flank steak should have an internal temperature of 120-130°F, medium-rare should be at 130-135°F, medium should be at 135-145°F, and well-done should be at 160°F or above.


Cooking flank steak requires careful attention to time and temperature. By following these guidelines and tips, you can ensure that your flank steak is cooked to perfection every time.

Just remember to adjust the cooking time based on the thickness of your cut and use a meat thermometer to check for doneness. With practice and patience, you can master this delicious cut of beef and impress your family and friends with a mouth-watering meal!
