Homemade Condensed Cream of Mushroom Soup

Making your own simple homemade cream of mushroom soup to have on hand for casseroles and cravings will help you avoid food additives and save money.

One of the quintessential ingredients in many homemade casseroles is Cream of Mushroom Soup. Mix a few vegetables, toss in cream of mushroom soup, stir, and bake.

It really is an amazing convenience food, which is why it has been a bastion of “home cooking” for decades.

The problem is that cream of mushroom soup – as well as other store-bought “cream of….” soups – is made more of industrially refined ingredients than it is of whole food.  According to Campbell’s Away from Home division, the ingredients in their classic cream of mushroom include:

  • WATER
  • MUSHROOMS
  • VEGETABLE OIL (CORN, COTTONSEED, CANOLA, AND/OR SOYBEAN)
  • MODIFIED FOOD STARCH
  • WHEAT FLOUR
  • SALT
  • MONOSODIUM GLUTAMATE
  • SOY PROTEIN CONCENTRATE
  • DEHYDRATED CREAM (CREAM [MILK], SOY LECITHIN)
  • YEAST EXTRACT
  • FLAVORING
  • DEHYDRATED GARLIC

Blech.

But cream of mushroom soup is so darn yummy – and so convenient! Thus, a few years ago I decided a homemade version was most definitely in order.

This is the recipe I included in my book, The DIY Pantry, and it makes the equivalent of one can of CONDENSED soup. If you’d like to make more to have on hand (so that it’s just as convenient as having the cans ready to grab), just scale up the recipe accordingly.

Also, please note that this is a CONDENSED version – I’ve created this recipe specifically to have a homemade version on hand to replace the cans of condensed soup, and while it certainly makes a delicious soup to eat just as soup (as opposed to in a casserole) and provides excellent real-food convenience, if you’re just in the mood to have mushroom soup for dinner, I recommend this recipe from Simply Recipes.

 

How to Store Homemade Cream of Mushroom Soup

One of the best reasons to make homemade cream of mushroom soup is to have it on hand for convenience. But unfortunately it can’t be canned at home easily, as the pH is too high to do it safely.

Thus, your best best is to freeze it in useable portions.

However, do change just one ingredient in the recipe if you freeze it: switch out the cornstarch for tapioca starch. Cornstarch tends to turns spongy when frozen, while tapioca remains more stable. Arrowroot is not recommended, unfortunately, as it renders dairy products slimy and ropy.

If you don’t have tapioca starch on hand, you can use flour and butter to create a traditional roux and add the blended ingredients, but it is quite thick (since it’s a concentrate), so it sometimes burns quickly, which is the reason I’ve created the recipe using starch in the blending phase rather than the roux method. This also has the advantage of being gluten-free. πŸ™‚ However, if roux is your only option, go for it!

And if you’d prefer not to freeze it, you can always skip this recipe altogether and use our homemade mushroom bouillon cubes to pull together a sauce the next time you need to make a casserole. πŸ™‚

    Why couldn’t this be pressure canned like other soups, stocks and meats? There is definitely not enough acid to safely can it in a hot water bath but why not pressure can it where the bacteria would be killed off? I don’t see why this couldn’t be done. Could please explain…

    • Kresha Faber says

      According to the USDA, milk products cannot be safely canned at home, even in a pressure canner. This is because – according to them – “milk products encapsulate any bacteria in the product including botulism and this encapsulation prevents the heat used in the canning process from killing the bacteria,” thus rendering them not only unsafe, but quite frankly, dangerous.

      Whether or not you agree with the USDA or trust they have your best interest at heart, botulism is real and it’s not to be messed with, so unless you have other information, I would tend to favor caution in this case. Which is a bummer, because it would be seriously great to be able to home-can homemade cream of mushroom soup, for sure!
