Notes
This roast is done once the meat falls apart. Depending on your slow cooker, it may be done in 8 hours or it could take up to 10. If it is still tough after 8 hours, add more time to your slow cooker. Let it cook until it starts to fall apart easily when pulled with a fork.Store leftover beef in an airtight container in the fridge.You can heat this in the microwave for 1-2 minutes per serving, or put the meat in a saucepan with some of the leftover juices and heat on low heat for about 5 minutes.
