Remove the outer leaves of the cabbage. Carefully remove the core and cut cabbage in half, then into 1-inch pieces. Place the pieces into the slow cooker.
In a small bowl combine the spices, then add to the slow cooker. Pour the broth over the cabbage, then place the butter pieces on top.
Cook on high for 2-3 hours. In the last 20 minutes, cook the bacon until crispy.
Remove the cabbage from the slow cooker with a slotted spoon and place it in a separate bowl. Discard the liquid in the slow cooker. Top with crispy bacon and serve.
