Sous Vide and frozen meat

In the Modernist Recipes Forum
I typically buy large vacu-sealed boneless Rib Roasts (Choice) from Costco and cut them into steaks approximately 5/8 of an inch thick. I then vacuum seal them, 2 to a package using a food saver system. When preparing them, I go directly from the freezer to a 135f water bath (using an Anova circulator) for about 2 hours. I then take them out, season them with salt and pepper and finish them on a hot grill for about 1 minute per side.
The result is quite disappointing. The bag after sous vide cooking has more juices than I would have expected. The meat has reasonably good flavor but is dry and not all that tender.
Can anyone give me an idea as to what I am doing wrong - is it the fact that I am using frozen meat? The same meat cooked on my grill without using sous vide is much better.

Hmm, your process sounds like it would work ok. Have you double checked the temperature of the water bath using a different thermometer?
Yes I have. I checked it with a digital thermometer and it was within 1/2 degree F of my setting
I was wondering if I would be better of to defrost the meat the meat first in the fridge, dry and season the meat then give it a quick sear before resealing it in a vacuum bag to finish cooking in the water bath.
I was also wondering if it would be better to use a zip lock bag without vacuum but evacuated of all air vs. a food saver with vacuum. In other words does the vacuum process draw juices out of the meat.
I've had great results with the following:

Season the meat before vac sealing

Sous vide at125f

Cook at least three hours

Sear briefly (45 seconds per side)

Let rest 3-4 minutes thereafter
Interesting, I cook straight from the freezer a lot. I know there was a post on Reddit talking about steak that was too dry / overcooked. Reading through the comments there might give you some options.
