When making casseroles, always heat the whole thing in the pan you have browned the meat or veg in. Then tip it in the slow cooker. For very long slow meat dishes, I just leave it on low overnight.
I do that too sometimes.
it can be used for so many thing apart from a meat stew.
Meat casseroles are fine done in the slow cooker.
If cooking something that doesn't need browning first, I always cook the onions in the microwave in a little stock first.
