At Avdaye, we add lots of tips in all of our recipes – because we are a home cook without any formal training, and we find we are more confident making dishes when we understand why it works, and what each ingredient means to the flavor of a recipe. Our goal is for even the most beginner home cook to feel empowered in the kitchen.
Condensed Cream of Mushroom and Onion Soup
We didn't grow up in a house with casseroles. Our mom says she was not a “casserole girl” and was a bit skeptical of all the fat (though, we remember we ate plenty of fattening foods like pizza and tacos- we didn't seem to eat foods loaded with cream of whatever soup). This is both a blessing and a curse- we love making fresh, good dishes but there is no denying that a creamy, warm and comforting casserole is about the most amazingly good food you can eat- but we didn't get to experience them until we were 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 good, 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. We 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 good base for other soups and stews.
