Corned beef Reubens are one of my all-time favorite sandwiches. The salty and heavily spiced corned beef compliments the tangy sauerkraut, with some sharp Swiss cheese and hearty rye bread topped with some Russian Dressing, tying it all together.
While I'll eat Reubens cooked almost any way, I especially love them when the corned beef is sous vided at 131°F (55°C) for a few days. It comes out so moist and tender, but still has an amazing bite that really works well in Reubens.
For a more traditional texture, you can cook the corned beef at 176°F (80°C) for 12 to 24 hours. Or go for 156°F (68.9°C) for a firmer, but still tender result.
I like to make homemade corned beef since it gives me complete control over the salt and seasonings, but this recipe also works well with most store bought brands.
Some corned beef can be really salty. If you find this is usually the case for you, or you don't like salt much in general, you can soak it in a container of clean water for a few hours, or even overnight. This will help pull out some of the salt, making it more palatable.

Once it's cooked, you can sear the corned beef if you want to, though traditionally it doesn't have a sear on it. Also, when slicing it, you can go as thick or thin as you want. Some people, like my Dad, want it sliced as thin as possible, while others prefer a thicker slab.
This recipe makes 4 sandwiches, though it can be hard to find a small corned beef. I usually make a regular sized 3 to 5 pounder and eat it several days in a row, with cabbage, Reubens, and corned beef hash. The larger corned beef doesn't change the cooking time at all.
I often toast my rye bread before making the sandwich, but if you prefer it untoasted that is fine as well. The sauce is usually Russian dressing or Thousand Island dressing, though I usually use Sir Kensington's Special Sauce.
I'm lucky to have several great butchers in my area, but sometimes I want to up my game and will turn to Snake River Farms, they have a wide variety of beef including Prime, American Wagyu , and dry aged. I also enjoy trying the different ranchers that Crowd Cow has available including their wagyu.
