I did the sous vide rump roast as a pot roast, air fryer roasted the vegetables (substituted cauliflower for most of the potatoes) and made a Guinness/brown sugar reduction for the sauce. The vegetables turned out great. The meat was fine, too, but in a pot roast I usually want falling apart.
I did it at 138 so basically medium, and the meat was mostly intact. It's more like I'd want from a London broil. If I do this again, I'll probably actually go full eye of round on it, slice it thinly like roast beef, and have the veggies as sides.
So my initial opinion is even low and extremely slow (50 hours), sous vide doesn't really get pot roast right and it forces you to do the cooking separately, sort of thwarting the whole point of a one pot dish. The meat really needs to be together with the vegetables.
Next time I'll try doing it like a London broil, because the meat would have been perfect sliced thin.
