Sous Vide Flank Steak

[TdeV]

This Saturday we'll be having a Wine Time. Sous vide flank steak is planned as one of the dishes.

 

The flank steak is 1.6 lbs, about 10" - 14" long (it's currently folded). The plan is to marinate for a few days, then sous vide.

 

In the past we've sautéed after the sous vide has finished. Currently, no outdoor barbecue.

 

Suggestions? Recommended time and temperature?

Years ago, I used to make flank steak SV pretty regularly.  My goto was 131F for 24 hours, then torch before serving.

I concur w @KennethT

 

sometimes the ends of the FS are quite gnarly .  consider minimal trim there.

 

when torching , make sure the surface is dry , or flash sear in a hot pan.

I used to grill , after marinating 24 hrs , on a very hot grill .

 

just to get a quick but decent char on each side , then rest .

 

then slice thinly .  the meat was rare , but sliced thinly , was tender and extraordinarily delicious .

I do flank steak @133F for 4 hours followed by a fast sear.

This is what I do too. Not much help to someone without an outdoor cooking setup. I always grill it. A hot sear followed by a Searzall touch up would be my advise for indoor. It’ll be hard to get even contact with the pan after SV, so use a lot of fat and a grill press if you have one. 
 

I think I usually did 133 for 4 to 6 hours. Modernist Cuisine says you can treat flank as either tender or tough, so holding it for 24 hours isn’t out of the question.

If you choose to treat FS as tender , then you slice it very thinly 

 

if you treat at tough , and cook it accordingly to tender , then you can slice thicker.

 

very rare , sliced thinly , is a revelation .
