Place all ingredients in your slow cooker and cook for 6-8 hours on low or until beef is really tender.
When your beef is almost ready thicken it with gravy powder. Use 3tsps of gravy powder and mix it with 3tbs of water pour it in your slow cooker mix well and repeat till sauce is lovely and thick.
Take the bay leaves out of your slow cooker and then your dish is ready serve. I love mine served with a good mashed potato.
Notes
Even if you don't like beer (like me) you will enjoy this dish. The beer flavour is very subtle and it helps makes your beef extra tender. Chose a beer that you can tolerate the flavour of if you can, I like using Cascade Draught or Pure Blonde. This casserole makes a fantastic beef and beer pie as well, if you search Beef and Beer Pie on this website you can see my step by step instructions.
