Slow Cooker Sirloin Steak with Gravy Recipe. Fork tender sirloin steak served with buttery mashed potatoes and covered in gravy.
If it comes out of a slow cooker there is a 99% chance it is comfort food. Serve this slow-roasted sirloin steak with a side of mashed potatoes. Then drown it in gravy for an ultimate comfort food dinner.
We are not talking about gravy from a packet either. We are talking about the real thing! The gravy is made with the natural flavors of the steak when it is seared and other seasonings.
Then the sirloin steak is slow cooked in the gravy for flavor and tenderness.

I think the only thing I haven’t done is breakfast in my slow cooker. I sleep for 10 hours and anything I put in the slow cooker the night before would be a dried-up brick by the time I get up.

This recipe was a delicious surprise! We followed the recipe to a tee and it was great. We cooked on high for 4 hours and it was more than at temperature. I'll definitely be trying this again. Also wondering what other meats could be used. Thanks for the recipe!
