At Sweet C’s, I add lots of tips in all of my recipes – because I am a home cook without any formal training, and I find I am more confident making dishes when I understand why it works, and what each ingredient means to the flavor of a recipe – my goal is for even the most beginner home cook to feel empowered in the kitchen.

I want each reader to walk away with a solid knowledge of each recipe, with all of the tips I’ve gathered from extensive testing of each recipe. I also answer questions my friends and family have asked about my recipes, to help everyone better understand the processes we use – and why!

Easy Condensed Cream of Mushroom and Onion Soup

I didn’t grow up in a house with casseroles. My mom says she was simply not a “casserole girl” and was a bit skeptical of all the fat (though, I remember we ate plenty of fattening foods like pizza and tacos- we just didn’t seem to eat foods loaded with cream of whatever soup). This is both a blessing and a curse- I love making fresh, delicious dishes but there is no denying that a creamy, warm and comforting casserole is just about the most amazingly delicious food you can eat- but I didn’t really get to experience them until I was in college in the midwest. This Homemade Condensed Cream of Mushroom and Onion Soup is a grew balance for people who are trying to eat whole, unprocessed foods that don’t take much time to make, but want the delicious, creamy and warm addition of a creamy soup base for a casserole.

This condensed soup base is extremely versatile- and can also be made vegan to add to quinoa or rice in a breeze. I personally love it with chicken and broccoli (casserole recipe to follow!) or add more water to use as a soup. You can even use this as a delicious base for other soups and stews.

    As an amend to my previous comment. I added a few more sliced mushrooms as I felt I had chopped the others to small ad I wanted to see some chunks. Also added a bit more flour so now its perfect inmmy opinion.

  2. Linda Chambers says:

    Made this soup and while it looks and smells wonderful it didn’t thicken up as much as I thought but it’s like a soup.
    Maybe because I couldn’t use cream.
    Anyway, putting it over the meatballs and I’m sure it will get rave reviews

  3. Diana Raymond says:

    I use this recipe often! We love it as soup.
    Perfect for Green Beans Casserole /aka Green Bean ala Nash. And fantastic for other favorite casseroles.

  4. Pam says:
