Freezing chard

Anyone bother to freeze chard?  Do you have to blanch first?

I’ve never done it. But I guess blanch first.
When I played at being a chef. We used to get bags of frozen spinach. It was in pre chopped little blocks.
I guess you could do the same with chard.

I know the things you mean, spinach bricks. I suppose I could blanch and stuff into spread boxes and then micro when I wanted it

I freeze chard and spinach sometimes I blanch but mostly I don't bother especially as its mostly used in curries and soups.
