What You Need to Make Sous Vide Flank Steak

2. A large pot or container to hold the water for your sous vide machine

3. A vacuum sealer (optional but recommended)

4. Flank steak

To Marinate or Not?

One of the great things about cooking flank steak sous vide is that you can marinate the meat before cooking if you’d like.

This gives you the opportunity to infuse the steak with whatever flavors you like.

Just be sure to remove any large chunks of herbs or spices before sealing the bag, as these can clog up the vacuum sealer.

If you don’t want to marinate the steak, that’s totally fine too. Just season the meat with salt and pepper before sealing it in the bag.

How to Make Sous Vide Flank Steak

Now that you have all the supplies, it’s time to get cooking! Follow these simple steps to make sous vide flank steak:

1. Preheat your sous vide machine to the desired temperature. For medium rare flank steak, we recommend cooking at 131 degrees Fahrenheit.

2. Season your flank steak with salt, pepper, and any other desired spices.

3. If you’re using a vacuum sealer, seal the seasoned steak in a vacuum-sealed bag.

4. If you’re not using a vacuum sealer, place the steak in a zip-top bag and slowly lower it into a pot of water to remove the air from the bag.

5. Once the steak is sealed in a bag, lower it into the water bath and cook for 1-2 hours.

6. When the flank steak is cooked to your liking, remove it from the water bath and pat dry with a paper towel.

7. If you like, you can sear the steak on a hot pan or grill to create a nice crust. This step is optional but recommended.

8. Slice the flank steak against the grain and serve with your favorite sides. Enjoy!

Tips on Thickness for Sous Vide Flank Steak

Thickness is important when cooking sous vide flank steak. If the steak is too thin, it will cook too quickly and may become tough.

The thickness of your flank steak will impact the cooking time.

  • For a 1-inch thick steak, cook for 1 to 2 hours at 130°F.
  • For a 1.5-inch thick steak, cook for 2 to 4 hours at 130°F.
  • And for a 2-inch thick steak, cook for 4 to 6 hours at 130°F.

If the steak is too thick, it will take longer to cook and may not be as tender. For best results, aim for a thickness of 1-1.5 inches.

Can You Marinate a Flank Steak Before You Sous Vide It?

You can marinate your flank steak before you cook it sous vide. This will infuse the meat with flavor and make it even more tender.

Just add the steak and marinade to a zip-top bag and let it sit for 1-2 hours before cooking.

However, you don’t need to marinate the steak for hours or even overnight. A quick 30-minute marinade will do the trick!

If you decide to marinate your steak, be sure to pat it dry before cooking. This will help prevent the meat from overcooking.

What are the Best Sous Vide Flank Steak Temperatures and Times?

Flank steak is best cooked at a lower temperature for a longer period of time. This will result in a more tender and juicy steak.

Steak-Like:

-Rate: cook at 130°F for 1-2 hours

-Medium Rare: cook at 135°F for 3-4 hours

-Medium: cook at 140°F for 4-6 hours

-Well Done: cook at 145°F for 6-8 hours

Tender Steak:

-Medium Rare: cook at 145°F for 4-6 hours

As you can see, the cooking time will vary depending on your desired level of doneness. We recommend cooking at a lower temperature for a longer period of time for the most tender and juicy steak.
