Sous vide cooking is a popular technique that has taken the culinary world by storm. It involves cooking food in vacuum-sealed bags at a precise temperature for an extended period. One of the most commonly cooked sous vide meats is flank steak, which is known for its bold flavor and tenderness.

If you’re wondering how long you can cook a flank steak sous vide, the answer depends on a few factors. Let’s take a closer look at these factors and how they affect cooking time.

Thickness of Flank Steak:
The thickness of the flank steak plays a crucial role in determining how long it needs to be cooked. A thinner cut of meat will cook faster than a thicker one. A recommended thickness for flank steak is around 1 inch, which takes about 2-3 hours to cook sous vide style.

Desired Doneness:
Another factor that affects cooking time is how well done you want your steak to be. If you prefer your meat rare, it will need less time to cook than if you want it well-done. For example, if you want your flank steak medium-rare, it should be cooked at 130°F (54°C) for about 2-3 hours.

Food Safety:
It’s important to follow food safety guidelines when cooking sous vide. Cooking at the right temperature and for the right amount of time ensures that harmful bacteria are eliminated from the meat. The USDA recommends cooking beef at 130°F (54°C) for medium-rare doneness and 140°F (60°C) for medium doneness.

Overall Cooking Time:
To determine the overall cooking time for your flank steak, consider all these factors – thickness, desired doneness and food safety requirements – as well as any personal preferences you may have regarding taste and texture.

Here’s an example recipe:

Ingredients:

Place the seasoned steak in a vacuum-sealed bag or Ziploc bag with olive oil. 4. Place the bag in the preheated water bath and cook for about 2-3 hours, depending on the thickness of the meat and desired doneness.

5. Once cooked, remove the steak from the bag and pat dry with paper towels. 6. Heat up a cast-iron skillet over high heat with some oil. 7. Sear the flank steak on both sides for about 1-2 minutes each until it gets a nice crust on both sides. 8. Rest it for a few minutes before slicing.
