Jamie's Easy Slow-cooked Beef Stew - I halved the recipe and it completely filled my slow cooker. The broth in this is amazing - I think cooking some udon or ramen noodles in it would be a great way to use the leftovers.
Slow Cooker Guinness Beef Stew Need to make a rue and add more flour at the end to make a thicker stew like broth. I also added 2 stalks of celery. Didn't have tomato paste so left it out but would try it with as well.
