And yes, extending a can of soup with add ins is a nice, quick way to get a good soup. I've done it many times.
But nothing, and I mean nothing, beats a soup made from scratch.
Yes, it can take hours to simmer chicken to get a stock.
And hours more to assemble and cook the perfect chicken vegetable, chicken & rice, beef and mushroom, or ham and bean, but nothing that comes out of can will ever match that.
Depending on the soup, I'll start them on Saturday and finish them Sunday (if I'm making a full stock from scratch).
Or, I'll pull a couple of containers of stock out of the freezer and assemble the soup on Sunday and have it for dinner and lunches the following week.
One thing I really need to get into the habit of is saving my vegetable scraps (carrot tops, peelings, onion tops, etc.) in a bag in the freezer for stock base. I already do that with chicken bones.
