Recipe Notes

I made sure that this homemade diy Condensed Cream of Mushroom Soup had a ton of flavor so I used 8 oz. of mushrooms ( think the usual size container you can buy in your grocery store ). It is also accidentally gluten free since I didn't use flour but rather cornstarch. It is my secret ingredient to smooth and silky sauces.

You can use it in casseroles, like a family favorite Green Bean Casserole, or turn into a mushroom sauce to pour over chicken ( it would be perfect for our Creamy Garlic Mushroom Chicken and it will save you a step! ) or add chicken or vegetable stock and make a creamy mushroom soup.

To make a sauce, use half of the mixture and add enough stock to get desired consistency. Heat up and serve.

Half and half is a mixture of light cream and whole milk. You can find it in the dairy section of your grocery store, near coffee creamers.
