Find out how to make homemade condensed mushroom soup to use in classic casseroles or other recipes as an alternative to using the canned stuff. Same great creamy mushroomy taste but you control the ingredients!

A lot of casserole recipes call for canned condensed cream soup. Since we’re doing a series on classic casseroles, we thought it was important to give you an alternative to the canned stuff.
The other day I posted a photo-tutorial for making homemade condensed cream of chicken soup. That recipe can be used anywhere that canned condensed soup is called for.
However, sometimes you want a condensed soup with a different flavor than just chicken. So I thought I should show you that the same recipe can be switched up to accommodate different ingredients.
Time for Condensed Cream of Mushroom Soup! For the chicken soup, you simply add the cooked chicken meat at the end. For the mushroom soup, you do the same thing, adding finely chopped cooked mushrooms at the end. The recipe also has a quick instruction for cooking the mushrooms.
If you instead wanted, for instance, cream of celery soup, you would finely mince a half cup of celery, sauté it in 2 teaspoons of butter until very soft, and then add it to the soup mixture at the end. Simple, right?
The recipe for the condensed cream of mushroom soup is below. If you want some photos to go along with the process, have a look here.
Now all we need are some casserole recipes to go with all this condensed soup. Well, stay tuned because those are coming right up!!!

Loved your talk about mushroom soup. Used to be my favourite as a kid. To cook with as a middle aged housewife. Then I stopped using the commercial canned stuff. I noticed your recipe didn’t have cream in it. Looked perfect to me.
Thanks, Melody! I hope you enjoy it.
