I sous vide my steaks at 125 F before searing for about 30 seconds on each side. I like mine medium rare, but closer to rare than medium.
Sometimes I cold smoke the steaks first before sous vide.
Here's a chart I made after trial and error. YMMV
Sous Vide temps and times:
Chicken breast (served hot or cold, either way) - 140 F for 2 hours (salt 30 min. to 2 hr. ahead of time)
Pork chops - 140 F for 1 hour (salt 30 min. to 2 hr. ahead of time)
Halibut - 130 F for 1 hour (salt 30 min. ahead of time) - remove skin and sear in butter
Salmon - 120 F for 1 hour (salt 30 min. ahead of time) - sear afterward with skin on
Rack of Lamb - 130 F for 1 1/2 - 2 1/2 hours - sear
Steak - cold smoke with Mesquite for about an hour, sous vide at 125 F for at least an hour - sear for 30 seconds per side, plus edges (550 F on pellet grill, on Grill Grates - flat side)
Lobster - 140 F for 20-60 minutes - can put butter in bag first
Ham - 140 F for 3 hours or more - leave in cryovac (I used turkey fryer pot to fit the ham)
