One of the most important steps in preparing Sirloin steak tips (or any cut of beef) for the slow cooker is to brown the meat. Although you can add raw meat directly to the slow cooker, browning (or searing) the meat adds a lot more of the deep, rich flavor that you expect from a beef stew.
To properly brown your Sirloin tip steak cubes, place the meat into a hot pan and cook them for a couple of minutes, until the bottom develops a nice, dark crust. Turn the cube over sear, repeating for each side for the meat.
The name of this meat cut can be a little misleading. The Sirloin tip does not actually come from the Sirloin cut nor is it the tips of steaks. So keep this in mind when shopping for a low carb beef dishes calling for it. Sirloin tips actually come from the Round portion of the hindquarter, which runs from the ankle to the rump.
