I adapted this for a slow cooker (boneless chicken thighs, adjusted the liquid) and it was a big hit. The lemon and dill were a nice touch. Definitely a keeper.
I've made this a couple of times now and it is a crowd pleaser for my family of four. I like the whole grains and my husband likes that it is a stew instead of a soup. Once I substituted wheat berries by par boiling them for 20 min and then proceeding with the recipe as written. We also substitute parsley for the tarragon because I just don't keep tarragon around.
I love beef and barley soup. The chicken and barley combination with dill and lemon is a great flavor profile. I thought this was a great recipe. I didn't add tarragon. I don't like it. However, if you like tarragon, it would fit in flavor wise. It is hearty and satisfying.
