Should you, and how do you, grease a crockpot? I know that this may be a silly question but I came across a crockpot recipe that asks for the crockpot to be greased before adding the ingredients into the pot. Do you just grease the pot normally? In my case with a bit of olive oil and paper towel. Are you required to grease a crockpot or is it just simpler. I don't want the food to extra greasy.
Personally, I've never made a dish that required greasing of the crockpot - even if it called for it, I've ignored that step and had no problems.  I can only imagine the step is added to ensure nothing sticks - but my crockpot (and all others I've seen) are glazed porcelain or ceramic, and the recipes always include a liquid of some kind, so I don't think that's going to be a problem.

If I were going to grease it, however, I'd do it in the method you described, and use a very light touch.
