Heat the oil and sear the meat for a couple of minutes each side and then place in the slow cooker. Throw in the peeled onions and garlic along with the bay leaves, rosemary, salt and pepper.
Add the water to the pan to de-glaze it and then pour on top of the meat. Set the slow cooker on low for about 8 hours and that's it!
We served ours on top of pan-fried polenta accompanied by julienne vegetables. Enjoy!
