Can lamb shanks be cooked in a slow cooker and if so for how long so that the meat is tender and coming away from the bone?

Go on the internet because there must be a ton of recipes. Brown the meat on all sides first in a pan and then transfer them to the slow cooker with whatever you are cooking them with.

I don't braise lamb shanks before cooking. I bake them in the oven with lots of onion and garlic and cook till the meat is falling off the bone. Would say about 2 hours slowly in a 325 oven .
