Cream of Mushroom Soup Base (for the freezer)

Last week on our ad-based shopping list was white mushrooms. They were on sale for $1.00 a carton, which is a great price. The problem many people run into when fresh produce goes on sale is how to preserve or use it all before it ages out and you've wasted your money buying so much. So problem number one.

Problem number two: trying to make a recipe that sounds delicious only to get to the end and see that it calls for a can of cream of something soup, often cream of mushroom. In trying to eat food that we can identify all the ingredients in, cans of soup just doesn't fit in. It stinks though, as there are recipes that look and sound delectable except for that one ingredient.

The solution? Make your own! By doing so you can use up that great deal without letting it slip away, have easy food in the freezer that can be used in so many ways and try out some of those recipes that call for cream of whatever soup (most are pretty interchangeable).

This is my cream of mushroom soup base. I bought 4 cartons of mushrooms this last week, as I knew I didn't have tons of freezer space and we don't go through too many mushrooms, though 3/4 of the family loves them (Pony Gal can be pretty hit or miss). It is so simple and fast to do, buying those cans seems foolish!

(As a note: these pictures were taken during the fourth batch of soup base in the same pan, so the pan is getting rather crusty looking, lol.)

Cream of Mushroom Soup Base
1 carton (8 oz? the squarer version, not a larger rectangular one) mushrooms. Any will work, though in general the white button style are what goes on sale and are easiest to find
3 T butter
2 heaping T all-purpose flour
1 1/2 t thyme
1/2 t fresh ground black pepper
2-3 cups milk
salt to taste

Start by chopping your mushrooms to the size you prefer. We like ours somewhere between a dice and chunky. While you are chopping melt the butter in a sauce pan over medium heat. Once the butter is melted add the mushrooms, thyme and black pepper.

Saute until the mushrooms have changed to a darker brown and softened.
Once this happens, you will build a roux around the mushrooms, like if you were making a creamy breakfast gravy. Add the flour and cook for about 1 minute (otherwise you'll have a floury taste to the soup base. Yuck.)

Dump in your milk- I honestly eyeball this as I know with what pan I use how much I need. I err on the side of too much and let it cook back down to a creamy consistency, like that of a thick gravy, if it was too much. Stir the milk in and stir from time to time until your base reaches a nice creamy consistency.

Taste and add salt to taste-usually at least 1/4-1/2 t.

Let cool and put in labeled containers in the freezer.

We use ours for soup (add milk and more seasoning to taste and thickness), added to casseroles in place of canned condensed soup (comes out to about one can per batch of this recipe) or added to creamy, roux based gravies like what we use on chicken fried steak-oh my yumminess!


  1. I like cream of mushroom soup in stuff and have ruled out all recipes calling for it since I never have time to make it from scratch while cooking dinner. I never thought to make big batches and freeze them. Duh. Mathew makes a killer cream of mushroom soup. Thank for the idea!

  2. Cream of mushroom soup was one of my favorite meals growing up, even though we always had the canned version. It was where I started learning how to experiment with making food taste better. You'll have to bring me out a bowl of Mathew's sometime. I love it. I was fighting the urge to eat the soup base last night, in fact. It has been a long time since I had any. I always space off making it but when the mushrooms went on sale a light bulb somewhere went off.

  3. Seems like a good waste of cream to me...

  4. Or more appropriately, a waste of good cream..

  5. would the recipe be the same for cream of celery?

  6. A good waste of cream, yes. A waste of good cream, no, but I expected that from you, Randy. In fact, I was surprised it took you so long to weigh in on a post about mushrooms.

  7. Sarah,
    I would think you could do the same thing, but instead of thyme, maybe use something else-parsey, or a little onion or garlic? I haven't ever had cream of celery soup, because I really only ever use celery as a filler and rather dislike celery. It should come together the same way, I just don't know what other flavors you might use. Maybe a little chicken stock at first with the roux, then slowly add in the cream.


I welcome hospitable, intelligent discussion. I do not welcome mean-spirited comments. Though they are "moderated" I post pretty much everything, with a very, very small exception-that being spam and those who aim to hurts others intentionally. I'd love hear what you have to say, otherwise!
