When it comes to cooking flank steak, achieving the perfect level of doneness can be a challenge. Traditional cooking methods, such as grilling or pan-searing, can result in a steak that is overcooked or undercooked in certain areas. However, with the advent of sous vide cooking, it is now possible to cook flank steak to a consistent and precise level of doneness. In this article, we will explore the world of sous vide cooking and provide a detailed guide on how long to cook flank steak using this innovative method.
Understanding Sous Vide Cooking
Sous vide cooking is a method of cooking that involves sealing food in airtight bags and then cooking it in a water bath at a precisely controlled temperature. This technique allows for even cooking and eliminates the risk of overcooking or undercooking. Sous vide machines are designed to circulate water at a consistent temperature, ensuring that the food is cooked uniformly throughout. This method is particularly well-suited for cooking flank steak, as it allows for the precise control of temperature and cooking time.
The Benefits of Sous Vide Cooking for Flank Steak
There are several benefits to cooking flank steak using the sous vide method. Even cooking is one of the primary advantages, as it ensures that the steak is cooked to a consistent level of doneness throughout. Additionally, sous vide cooking allows for precise temperature control, which is essential for achieving the perfect level of doneness. Furthermore, sous vide cooking helps to retain the natural flavors and juices of the steak, resulting in a more tender and flavorful final product.
Preparation and Seasoning
Before cooking flank steak using the sous vide method, it is essential to prepare and season the steak properly.

What is sous vide cooking and how does it work for flank steak?
Sous vide cooking is a method of cooking where food is sealed in airtight bags and then heated in a water bath to a precise temperature. This technique allows for even cooking and prevents the food from being overcooked. For flank steak, sous vide cooking is ideal because it can be a challenging cut to cook to perfection using traditional methods. The low and slow heat of the water bath breaks down the connective tissues in the steak, making it tender and flavorful.
The precise temperature control of sous vide cooking also ensures that the steak is cooked to a consistent doneness throughout. Whether you prefer your steak rare, medium-rare, or medium, sous vide cooking can achieve the perfect level of doneness. To cook flank steak using sous vide, simply season the steak with your desired spices and seal it in a bag. Then, place the bag in the water bath and set the temperature according to your desired level of doneness. The result will be a perfectly cooked steak with a tender and juicy texture.
What are the benefits of using sous vide cooking for flank steak compared to traditional methods?
The benefits of using sous vide cooking for flank steak are numerous. Firstly, it allows for even cooking and prevents the steak from being overcooked. Traditional methods of cooking flank steak, such as grilling or pan-frying, can result in a steak that is burnt on the outside and undercooked on the inside. Sous vide cooking eliminates this problem by cooking the steak to a precise temperature throughout. Additionally, sous vide cooking allows for greater control over the cooking process, making it easier to achieve the perfect level of doneness.
Another benefit of sous vide cooking for flank steak is that it can be cooked ahead of time and then finished with a quick sear just before serving. This makes it ideal for entertaining or for busy weeknight meals. Simply cook the steak in the sous vide machine and then give it a quick sear in a hot pan just before serving. The result will be a steak that is both tender and flavorful, with a crispy crust on the outside. This level of control and flexibility is not possible with traditional methods of cooking flank steak, making sous vide cooking a game-changer for anyone who loves to cook steak.
What are the recommended sous vide cooking times for flank steak?
The recommended sous vide cooking times for flank steak depend on the desired level of doneness. For a rare steak, cook the flank steak in the sous vide machine at 130°F (54°C) for 1-2 hours. For a medium-rare steak, cook the steak at 135°F (57°C) for 1-2 hours. For a medium steak, cook the steak at 140°F (60°C) for 1-2 hours. It’s essential to note that the cooking time may vary depending on the thickness of the steak and personal preference.
It’s also important to note that the steak should be seasoned and sealed in a bag before cooking. Additionally, the steak can be cooked for a longer period, such as 2-3 hours, for a more tender and fall-apart texture. After cooking, the steak can be seared in a hot pan to add a crispy crust on the outside. The result will be a perfectly cooked steak with a tender and juicy texture. By following these recommended cooking times, you can achieve the perfect level of doneness for your flank steak and enjoy a delicious and memorable meal.
How do I determine the perfect internal temperature for my flank steak?
To determine the perfect internal temperature for your flank steak, you need to consider your personal preference for doneness. The internal temperature of the steak will vary depending on the level of doneness. For a rare steak, the internal temperature should be around 120°F – 130°F (49°C – 54°C). For a medium-rare steak, the internal temperature should be around 130°F – 135°F (54°C – 57°C). For a medium steak, the internal temperature should be around 140°F – 145°F (60°C – 63°C).
It’s essential to use a thermometer to check the internal temperature of the steak, especially when cooking using sous vide. The thermometer should be inserted into the thickest part of the steak, avoiding any fat or bone. By using a thermometer, you can ensure that your steak is cooked to the perfect internal temperature, and you can avoid overcooking or undercooking the steak. Additionally, it’s crucial to note that the internal temperature will rise slightly after the steak is removed from the heat, so it’s better to aim for a temperature that is slightly lower than your desired doneness.
Can I add flavorings and marinades to my flank steak before sous vide cooking?
Yes, you can add flavorings and marinades to your flank steak before sous vide cooking. In fact, adding flavorings and marinades can enhance the flavor and texture of the steak. You can season the steak with your desired spices, such as salt, pepper, and garlic, and then seal it in a bag with some aromatics, such as thyme and rosemary. You can also add a marinade to the bag, such as soy sauce or olive oil, to give the steak a rich and savory flavor.
When adding flavorings and marinades, it’s essential to ensure that they are evenly distributed throughout the steak. You can do this by massaging the seasonings and marinades into the steak before sealing it in the bag. Additionally, you can add some acid, such as lemon juice or vinegar, to the marinade to help break down the connective tissues in the steak. By adding flavorings and marinades, you can create a delicious and flavorful steak that is both tender and juicy. The sous vide cooking process will then evenly distribute the flavors throughout the steak, resulting in a perfectly cooked and flavorful meal.
How do I sear my flank steak after sous vide cooking to achieve a crispy crust?
To sear your flank steak after sous vide cooking, you need to heat a skillet or grill pan over high heat. Add some oil to the pan, such as olive or avocado oil, and then add the steak. Sear the steak for 1-2 minutes per side, depending on the thickness of the steak and the level of browning you desire. You can also add some butter or other aromatics to the pan to enhance the flavor of the steak.
The key to achieving a crispy crust is to get a good sear on the steak. This can be done by using a hot pan and not moving the steak too much. You can also use a blowtorch to add a crispy crust to the steak, especially if you are cooking in a kitchen with limited stovetop space. By searing the steak after sous vide cooking, you can add a crispy and caramelized crust to the outside of the steak, while maintaining a tender and juicy interior. The result will be a perfectly cooked steak with a delicious and satisfying texture.
