The beauty of this homemade soup is that it contains fresh ingredients which really take the taste to another level. You can use almost any type of mushrooms you enjoy, but my favorites are white button mushrooms and a mix of portobello and shiitake mushrooms.

Because this soup is made from scratch, you won’t find any junky ingredients and it can be used as a healthy substitute for the whole family. Use it to make your favorite Green Bean Casserole or as the sauce in a big bowl of Creamy Pasta!

How to make cream of mushroom soup from scratch

To make cream of mushroom soup from scratch, all you’ll need is a food processor and a saucepan. The ingredients are pulsed together, then warmed up and simmered on the stove until creamy and velvety. Follow the steps to put this creamy dish together:

Pulse all of the ingredients together except the mushrooms in a food processor. 

To finish, add the whole mushrooms and pulse a few times to break them up. If your mushrooms are on the larger side, give them a rough chop before pulsing. 

Transfer the mixture to a saucepan, bring it to a boil, then let it simmer for about 10 minutes or until mushrooms are cooked through and soup has thickened. 

What to serve with mushroom soup

One of the best ways to use cream of mushroom soup is by mixing it into a casserole. It adds creamy, rich, and earthy flavors to a cabbage casserole or a cheesy cauliflower casserole.

Let’s not forget that it can be eaten as a main dish! All you have to do is whisk in one cup of vegetable or chicken broth and simmer until it’s heated through. Serve hot in a bowl with a spoon and a fresh green salad and a flaky buttered biscuit on the side.

How long does homemade cream of mushroom last?

To store: Any leftover mushroom soup can be placed in an airtight container in the fridge for one week. 

To freeze: To freeze leftover soup, add it to an airtight container or a freezer-safe bag and freeze for up to 3 months. Let it thaw in the fridge overnight before serving. You may need to stir in some stock or water to thin it out, and it may need to be pulsed in the food processor again if the milk solids have separated.

To reheat: The best way to reheat cream of mushroom soup is by pouring it into a saucepan and simmering over low heat until warmed through.
