Flank steak is a popular cut of beef that’s often used in dishes like fajitas, stir-fries, and sandwiches. However, cooking flank steak can be tricky since it’s a lean cut that can easily become tough and Chewy if overcooked.

So, how do you know when flank steak is cooked? Let’s take a look at some tips and tricks to help you get the perfect cook on your flank steak.

Tip #1: Use a Meat Thermometer

One of the easiest ways to tell if your flank steak is cooked is by using a meat thermometer. A meat thermometer will give you an accurate reading of the internal temperature of your steak, which will help you determine if it’s done cooking or not.

For medium-rare steak, aim for an internal temperature of 135°F (57°C), while for medium steak aim for 145°F (63°C). If you prefer well-done steak, aim for an internal temperature of 160°F (71°C).

Tip #2: Look at the Color

Another way to tell if your flank steak is cooked is by looking at the color. As the beef cooks, it changes color from red to pink and then brown. If you’re cooking your flank steak on a stovetop or grill, keep an eye on the color and flip it frequently until it reaches your desired doneness.

For rare:

– Internal temperature: 125°F (52°C)
– Appearance: Dark red center with bright red edges

For medium-rare:

– Internal temperature: 135°F (57°C)
– Appearance: Pink center with light brown edges

For medium:

– Internal temperature: 145°F (63°C)
– Appearance: Light pink center with brown edges

For well-done:

– Internal temperature: 160°F (71°C)
– Appearance: Brown throughout with no pink

Tip #3: Use the Finger Test

If you don’t have a meat thermometer or aren’t sure about the color, you can use the finger test to tell if your flank steak is cooked. This involves pressing the center of the steak with your finger and using the firmness as an indicator of doneness.

For rare, the steak should feel soft and squishy when pressed. For medium-rare, it should feel slightly firmer but still have some give.

For medium, it should feel firm but still slightly springy. And for well-done, it should feel very firm and springy.


Cooking flank steak to perfection takes practice and patience, but with these tips and tricks, you’ll be able to tell when your flank steak is cooked just the way you like it. Whether you use a meat thermometer, look at the color, or use the finger test, make sure to let your steak rest for a few minutes before slicing to allow the juices to redistribute evenly throughout the meat. Happy cooking!
