I have been making homemade condensed mushroom soup, for the freezer. The link still works on my older blog post, but I do not add the thyme to mine. I never know what I am going to use it for, so I leave that out, but the link for the recipe is on this: Blogpost.
The original recipe calls for cremini mushrooms. I used to find them in the stores, prior to covid, but all I can locate here, are organic white or baby bella (so I buy the baby bella). I did some research and baby bellas are basically the same as cremini mushrooms.
Mushrooms are very healthy for us, and I love this recipe, as it uses butter. Organic store bought condensed soup contains soy oil and other soy products. The recipe does contain a bit of flour, but I adapt the entire recipe using all organic/non-gmo ingredients. There is no corn starch in this recipe.It smells so good when it's being made. The link goes to a recipe site, and she had recipes for cream of chicken and cream of celery too. If I want a comfort meal, it typically involves homemade mushroom soup.
