The freezing and defrosting thing confuses me. Do you cook from frozen or defrost first
I cook from frozen. Six minutes normally does it, maybe a bit more if it's a very dense dish.
I use old take away containers and usually have around forty in the freezer.
Variety of fish pie, shepherds pie, chili, veg chili, butter chicken, daal, tomato pilaf, mushroom risotto, lamb hot pot, pork and bean casserole, tagine, loads of soups......... a few of these can be done in the slow cooker.
Just make four portions, eat one, fridge one for the next day, freeze two. It doesn't take much longer than making one dish.
I try to make a couple of big batches at the weekend.
I also chop a ton of onions in the blender, portion them out, bag them up and freeze them, gets you off to a quick start making something.
Also slice peppers and freeze them, they're fine in dishes. And make my own stock - I freeze bones and leftover ends and bits of veg to make stock when I have enough, then freeze the stock to use for soups and risottos.
I also freeze leftover red wine to throw in casserole.
But I have a large freezer and am very lucky.
