I've used pre cubed casserole steak today. It was in quite small pieces and I didn't brown it before adding it to the slow cooker. I have cooked it on high for about 5 hours and it isn't really really tender. It's ok but I wanted it to be falling apart when I cut it.
Should I have cooked it on low? Used bigger chunks? A different cut of meat? What do you use for super tender beef?
