Occasionally. It's not my favourite cooking utensil though. You need to pre-sweat onions otherwise they stay...squeaky. Also, I find that slow cookers seem to give everything a certain specific taste. I prefer the pressure cooker. It kind of achieves the same thing from the opposite end. Also, my oven has a slow cooker setting (170F) and throwing something into the oven in a le Creuset tastes so much better than the slow cooker, but I still need to sweat the onions.
