This homemade condensed cream of mushroom soup is a quick and easy alternative to canned varieties. It serves as a versatile base for various casseroles or can be enjoyed as a rich, creamy side dish.

List of ingredients

1 TBS butter – used for sautéing and creating the roux.
6 baby bella mushrooms – finely chopped for a concentrated flavor.
1/4 cup flour – acts as the thickening agent.
3/4 cup chicken broth – provides a savory liquid base.
1/2 cup milk – adds creaminess and richness.
1/2 tsp. garlic powder – for a subtle aromatic punch.
1/2 tsp. onion powder – adds depth to the savory profile.
Salt to taste – start with 1/4 tsp and adjust as needed.
1/8 tsp. pepper – for a hint of spice.

step-by-step instructions

Sauté Mushrooms: Melt butter in a saucepan over medium-high heat. Finely chop the baby bella mushrooms, add them to the pan, and sauté until they become tender.
Season: Stir in the salt and pepper to season the mushrooms evenly.
Cook Flour: Add the flour to the mushroom mixture and continue to cook for one additional minute to remove the raw flour taste.
Combine Liquids: Pour in the chicken broth and milk, then whisk the mixture constantly until it is completely smooth.
Flavor: Stir in the garlic powder and onion powder, continuing to mix the ingredients together.
Thicken: As the soup begins to thicken, reduce the heat to low and stir occasionally to prevent sticking.
Cool: Remove the saucepan from the heat and allow the soup to cool before using or storing.

Cooking Tips for Optimal Texture

Selecting the Best Mushrooms

Baby bella mushrooms, also known as cremini, offer a more robust flavor than standard white button mushrooms. Ensure they are firm and free of slime before chopping them finely for a uniform consistency in the soup.

Achieving the Perfect Roux

The combination of butter and flour creates a roux, which is essential for thickening the soup. Cooking the flour for one minute after adding it to the butter prevents the final product from tasting like raw flour.

Managing Heat Levels

Start with medium-high heat to brown the mushrooms and melt the butter quickly. Once the milk and broth are added, lowering the heat is critical to prevent the dairy from scorching or separating.

Whisking for Smoothness

Use a wire whisk rather than a spoon when incorporating the liquids. This helps break up any flour clumps instantly, ensuring the condensed soup has a professional, velvety texture.

Ingredient Substitutions

Vegetable Broth Alternatives

To make this recipe meat-free, replace the chicken broth with an equal amount of vegetable broth. This maintains the savory base while altering the flavor profile slightly toward a garden-fresh taste.

Dairy-Free Milk Options

Unsweetened soy milk or cashew milk can be used as a substitute for cow’s milk. These options provide a similar creaminess without the dairy, though the flavor may be slightly more nutty.

Using Different Mushroom Varieties

While baby bellas are recommended, you can use shiitake or oyster mushrooms for a deeper, more earthy flavor. If using shiitakes, remove the woody stems before finely chopping the caps.

Butter Replacements

If you prefer not to use butter, an equal amount of neutral oil or margarine will work. Note that butter provides a specific richness that enhances the overall flavor of the cream base.

Practical Ways to Use Condensed Soup

Green Bean Casserole Base

Mix this homemade condensed soup with blanched green beans and a pinch of black pepper. Top the mixture with fried onions and bake until the top is golden brown for a fresh take on a classic side.

Tater Tot Casserole Binder

Combine the soup with cooked ground beef and mixed vegetables to create a thick binding layer. Spread this in a baking dish and top with frozen tater tots before baking until crispy.

Creamy Chicken Pot Pie Filling

Stir the soup into a mixture of cooked chicken, peas, and diced carrots. Pour the mixture into a pie crust and bake, using the condensed soup as the primary thickening agent for the gravy.

Savory Pasta Sauce Base

Toss the soup with cooked fettuccine or penne pasta and steamed broccoli. Adding a splash of extra milk can thin the sauce slightly to better coat the noodles.

Storage and Preservation

Refrigeration Guidelines

Store the cooled soup in an airtight glass container in the refrigerator. It will remain fresh and safe to use for approximately 4 to 5 days.

Freezing and Thawing

This soup can be frozen in small portions for up to three months. Thaw the soup in the refrigerator overnight before reheating to maintain the best emulsion of the fats and liquids.

Container Selection

Use non-reactive containers, such as glass or BPA-free plastic, to store the soup. This prevents the soup from absorbing odors from other foods in the fridge and preserves the mushroom flavor.

Reheating and Consistency Adjustment

Stovetop Reheating Method

Place the chilled soup in a small saucepan over low heat. Stir frequently to ensure the bottom does not burn as the thickened mixture warms up.

Microwave Heating Tips

Heat the soup in 30-second intervals, stirring thoroughly between each burst. This ensures that the heat is distributed evenly and avoids hot spots that could curdle the milk.

Thinning the Soup

If the soup becomes too thick after refrigeration, whisk in a tablespoon of milk or chicken broth at a time. Continue adding liquid until the desired consistency is reached.

Thickening the Soup

If the soup is too thin, simmer it on low heat for a few extra minutes to reduce the liquid. Alternatively, whisk in a small cornstarch slurry (cornstarch mixed with water) and heat until thickened.

Common Cooking Troubleshooting

Preventing Flour Lumps

Lumps occur when flour is not fully incorporated into the fat or when liquid is added too quickly. Whisking vigorously and adding liquids in a steady stream helps maintain a smooth texture.

Stopping the Milk from Curdling

Curdling happens when dairy is exposed to excessive heat or high acidity. Keep the heat on low after adding the milk and avoid bringing the mixture to a rolling boil.

Balancing the Saltiness

Because chicken broth varies in sodium content, always taste the soup before adding more salt. Add salt in small increments at the very end of the cooking process.

Avoiding Burnt Butter

Butter can brown or burn if the heat is too high before the mushrooms are added. Ensure the butter is melted and bubbling slightly, but not turning dark brown, before adding the vegetables.

Frequently Asked Questions

Can I use fresh garlic instead of powder?

Yes, you can use fresh minced garlic. Sauté the minced garlic with the mushrooms for about 30 seconds before adding the flour to avoid burning the garlic.

How long does this stay fresh?

When kept in an airtight container in the refrigerator, the soup lasts for 4 to 5 days.

Is this recipe gluten-free?

This recipe is not gluten-free due to the flour. You can make it gluten-free by replacing the all-purpose flour with a 1:1 gluten-free flour blend or cornstarch.

Can I use dried mushrooms?

Yes, but you must rehydrate them in hot water first. Finely chop the rehydrated mushrooms and use a portion of the mushroom soaking liquid to replace some of the chicken broth for extra flavor.
