Chef John's Beef on Weck Sandwiches
There are many cuts of beef used for this, including top round, rump roast, and brisket, but I like to use a nice, thick top-sirloin roast. Instead of cooking it in the oven, I like to pan-roast this on the stove top. Since top sirloin roasts are only a couple inches thick, they cook relatively fast. They're also tender, flavorful, and because of their shape, very easy to slice thinly, which is one of the keys to this amazing sandwich.
