Ragwort
I would rather do batch cooking when I am at home and then re-heat a meal rather than use the slow cooker again.
I do that too.
This week I made chili (in the SC), pork and bean casserole, ham and pea soup both on the stove, and steamed some salmon and boiled some potatoes to have for work lunches.
The chili etc was all portioned out and frozen, 14 'ready meals' for when I get in from work.
This weekend I will be doing similar - veg chili this time, maybe a pasta sauce of some kind and a chicken and mushroom something, lasagna maybe, but I won't be using the sc for any this time.
But the other week I had a guest and things to do during the day, plus wasn't sure what time she was arriving, so I did lamb shanks in the slow cooker and they were great.
It's not a binary choice, you can use it some of the time, for some things and then choose a different thing for other things/other times. There's no need for anyone to choose between the sc and some other cooking method :)
