Flank steak is a popular cut of beef that is known for its rich flavor and tender texture. One of the best ways to prepare flank steak is by using a sous vide machine.
Sous vide cooking involves placing the steak in a vacuum-sealed bag and cooking it in a water bath at a precise temperature for a set amount of time. This method ensures that the steak is cooked evenly and retains its juices, resulting in a delicious and succulent meal.
So, how long should you cook flank steak in a sous vide? The answer depends on your desired level of doneness. The following are some guidelines to help you determine the ideal cooking time:
Rare: If you prefer your flank steak rare, set your sous vide machine to 130°F (54°C) and cook the steak for 1-2 hours.
Medium-rare: For medium-rare steak, set your sous vide machine to 135°F (57°C) and cook the steak for 2-3 hours.
Medium: To achieve a medium-cooked flank steak, set your sous vide machine to 145°F (63°C) and cook the steak for 2-4 hours.
Well-done: If you like your flank steak well-done, set your sous vide machine to 155°F (68°C) and cook the steak for 4-6 hours.
It’s important to note that these times are just guidelines, as the thickness of your flank steak will also affect the cooking time. Thicker steaks will require longer cooking times than thinner ones. Additionally, some people may prefer their steaks cooked slightly differently than these guidelines suggest.
To ensure that your flank steak reaches the desired level of doneness, it’s always best to use a meat thermometer. This will allow you to check the temperature of the meat without having to open up the bag.
When the steak is cooked to your liking, remove it from the sous vide bag and pat it dry with a paper towel. Preheat a cast-iron skillet over high heat and sear the steak for 1-2 minutes on each side to create a crispy crust.
In conclusion, cooking flank steak in a sous vide machine is an excellent way to achieve perfectly cooked, flavorful meat. By using the guidelines above and keeping an eye on the thickness of your steak, you can ensure that your flank steak turns out perfectly every time.
