Replacement for Cream of Mushroom Soup

If you're a regular visitor to our blog, you know how much we love casserole recipes. Growing up in the South gives you an appreciation for casseroles and everything about them, including condensed cream soups.

We've made (and eaten) more than our share of casseroles over the years and never thought twice about tossing in a can or two of cream soup. Until suddenly we had to think about it.

Either we didn't have a can tucked into the back of the cabinet, or we wanted a healthy alternative. That's when we started making our cream of chicken soup substitute and this cream of mushroom soup substitute. It makes the perfect replacement for canned soup in your favorite casserole with very little effort!

Ingredients and Possible Substitutions:

Milk: We use whole milk to make this recipe rich and creamy. Any variety of milk works. Keep in mind that milk with a lower fat percentage makes a less rich cream of soup alternative.
Flour: All-purpose flour works great to thicken this soup and mixes nicely with the milk. If you're using gluten-free flour, make sure it contains xanthan gum or another thickener.
Broth: Chicken broth makes a flavorful base for the soup, but vegetable or beef broth would also work. Each type of broth yields a slightly different taste and color, so it's up to personal preference. Bone broth is another great option. Water may be used, but the soup won't be nearly as flavorful.
Mushrooms: We prefer to use baby bella or button mushrooms because they are usually easy to find in supermarkets and they're not too expensive. Any type of mushroom works for this recipe, but different varieties of mushrooms give the dish a different flavor and color.
Seasonings: Garlic powder, onion powder, and salt. Adjust these to your taste and add any additional seasonings that you may enjoy.

Tips for Success:

To create a vegetarian mushroom soup replacement, use vegetable broth in place of chicken broth.
In a pinch, use jarred or canned mushrooms instead of fresh mushrooms.
Add extra seasonings like thyme, oregano, smoked paprika, fresh garlic, or a bay leaf for additional flavor.
Finely chop the mushrooms so they cook quickly and blend into the soup more easily.
We developed this recipe for use in casseroles. If you'd like to eat the soup instead, whisk in extra milk and seasonings to make it palatable. It's very thick like the soup that comes out of a can, so it's not meant to be eaten as-is.

Storage:

Refrigerator: Store unused mushroom soup substitute in the refrigerator for up to 4 days.

Can You Make This Recipe Gluten-Free?

Yes, absolutely! Swap the all-purpose flour for your favorite gluten-free blend and make sure the other ingredients are gluten-free. We've used Cup 4 Cup, Measure For Measure, and 1 to 1 Baking Flour with success.

Can You Make This Recipe Dairy-Free?

Yes, this recipe is very easy to make dairy-free. Use a milk alternative in place of whole milk. If you use a milk alternative with a strong flavor like coconut milk or almond milk, that flavor will come through in the flavor of the soup.

Is This Recipe Vegetarian?

No, it's not. However, if you use vegetable broth in place of chicken broth, then it becomes vegetarian. If you use vegetable broth and a milk alternative, it becomes a vegan substitute for mushroom soup.

How Much Homemade Cream of Mushroom Soup Does This Make?

This recipe makes about the same amount that you'd find in a 10 ½-ounce can of condensed cream of mushroom soup. The exact amount varies slightly since it depends on how much the liquid evaporates while the mushroom soup cooks.

Can You Double This Recipe?

Yes, for sure! Double, triple, or quadruple this recipe. Make as much cream of mushroom soup substitute as you need.
