The Top Sirloin Steak is probably one of the most affordable, good tasting steak beef cuts. The cut comes from the top of the sirloin butt (as opposed to the bottom sirloin butt which is where less tender cuts such as the tri-tip, and sirloin bavette).
There is a fat cap on top of the primal cut which is removed on the "cap off" version. This leaves you with a nice piece of steak which can be further cut into "center cut" which is what you find at your local Costco store. In fact Costco refers to their steak as the "Beef Loin Top Sirloin Steak Boneless Cap Off".
You can throw this steak on the grill with or without marinating it first. Don't over-grill it, medium rare is pretty perfect. Additionally this is my steak of choice for our Beef Stroganoff Recipe or even your favorite Beef Kabobs recipe. When using this for Stroganoff or any similar dish; slice the meat on the diagonal which helps to get a nice tender slice of steak.
My favorite kabob recipe combines top sirloin steak with fresh pineapple chunks, green bell pepper and yellow onion. You can marinate this first in your favorite marinade if you have time, otherwise just place them on the grill, they'll taste great.
Another great use is for a beef stir-fry recipe. Again, cut the meat thin, on the diagonal then cut it into bite-size pieces.
The last time we purchased this steak from Costco (2018) it was only $6.99 a pound so it's quite economical.
