I have only five or six crock pots and a slow cooker. I love making bread pudding or rice pudding in them. Yes, I buy the liners to go into the crock pot, 'cause clean up is a breeze that way. Last Thanksgiving, a year ago, I had more dishes than my double oven could handle, so I plugged in three of my crock pots and lined them. Perfect for the green bean casserole, the sweet potato casserole, and creamed corn. The slow cooker is used for baked beans...or take with us on picnics, off to family or friend's home. I do have a dipping crock pan, a one quart crock pot for the two of us, a four quart crock pot, and four eight quart crock pot. I seldom run them overnight, most of the time it is when we are home or having company that I use them.
I have a friend that lives by herself, makes a good soup in the crock pot and lives on it all week. Yes, good plastic bags take up less room than the crock pot or corning ware in the refrigerator. They also serve to 'gift' the guests with the leftovers...and not worry about returning any dish or pan.
I taught my bf how to do bread pudding in one, and now I says to her, you can make bread pudding at home; oh, no, said the bf, I have a friend that makes wonderful bread pudding, so I don't have too! I will just come here, she says. LOL!!
