I have a couple of the smaller Le Creuset pans, which are well used and not too heavy.
I have a LC smaller frying pan, which I use for omelettes, frittata and the like and it’s v good (but the handle is very long for the dishwasher).
I have a LC roasting tin, which makes wonderful roast potatoes, but I don’t use it much because it’s heavy.
My favourite is a LC casserole dish which is used every week.
My LC ware is blue and about 20 years old and it looks like it could go on for another 20... The interior of the casserole dish has certainly discoloured from cream to a sort of light caramel colour, but that doesn’t trouble me.
I consider my Le Creuset to have been a good investment and I recommend them.
