Flank steak is one of the most popular cuts of beef, known for its rich flavor and tender texture. However, cooking it to perfection can be a challenge, particularly when it comes to determining the ideal temperature.

In this article, we will explore the question “What temperature should a flank steak be?” and provide you with some tips on achieving the perfect cook.

Understanding Flank Steak

Before we dive into the ideal temperature for cooking flank steak, let’s first understand what this cut of meat is. Flank steak is taken from the lower chest area of the cow.

It is a long and flat cut of meat that can be tough if not cooked correctly. This is because flank steak contains a lot of connective tissue that needs to be broken down through proper cooking techniques.

The Ideal Temperature for Flank Steak

The ideal temperature for cooking flank steak depends on how you prefer your meat cooked. Here are some guidelines:

  • Rare: 125°F (52°C)
  • Medium Rare: 135°F (57°C)
  • Medium: 145°F (63°C)
  • Medium Well: 150°F (66°C)
  • Well Done: 160°F (71°C) or higher

It’s essential to note that these temperatures are just guidelines and that personal preference plays a significant role in determining how well-done your steak should be.

Cooking Techniques

Now that we know what temperature range to aim for let’s discuss some cooking techniques to achieve your desired doneness.

Grilling: Grilling is one of the most popular methods for cooking flank steak. To grill flank steak perfectly, heat your grill to high heat and sear both sides for about 3 minutes each. Then, reduce the heat or move the steak to a cooler part of the grill and continue cooking until you reach your desired temperature.

Broiling: Broiling is another great method for cooking flank steak. Preheat your broiler on high heat and place the steak on a broiler pan. Cook for about 4-6 minutes on each side, depending on how well-done you want your steak.

Sous Vide: If you have a sous vide machine, it’s an excellent way to cook flank steak to perfection. Simply season your steak, seal it in a bag, and cook in the sous vide machine at your desired temperature for about 1-2 hours. Then sear it on both sides for that perfect crust.


Cooking flank steak can be a bit intimidating, but with these guidelines and techniques, you’ll be able to achieve the perfect cook every time. Remember to check the temperature with a meat thermometer to ensure accuracy and always let your steak rest for a few minutes before slicing into it. Enjoy!
