Why is traditional cream of mushroom soup not gluten-free?
Conventional cream of mushroom soup, particularly the condensed kind used in casseroles and other recipes, is thickened with a roux made from wheat flour. For individuals with celiac disease, a serious autoimmune disorder triggered by gluten, or those with gluten sensitivity, consuming this soup can cause significant health problems. Even a small amount of gluten can trigger a reaction, so reading labels is absolutely essential for safe consumption. The use of wheat flour is a core part of traditional preparation, which is why historical favorites like classic Campbell's cream of mushroom soup are typically off-limits.
How to identify safe, store-bought gluten-free options
Fortunately, food manufacturers have responded to the growing demand for gluten-free products. You no longer have to avoid cream of mushroom soup entirely. Several major brands now offer certified gluten-free versions, which are specifically formulated with rice flour, modified cornstarch, or other gluten-free thickeners instead of wheat flour.
Reading the label is your first line of defense:
- Check for Certification: Look for a certified gluten-free symbol on the can or box, which indicates the product contains less than 20 parts per million (ppm) of gluten as mandated by the FDA.
- Read the Ingredients: Always scrutinize the ingredient list. Avoid products listing wheat flour, modified food starch from wheat, or any other gluten-containing grains. If the label states 'modified food starch,' and does not specify the source as gluten-free, it is best to avoid it unless certified.
- Verify the Brand: Be aware that some brands might offer a gluten-free line alongside their traditional products. For example, Campbell's now has a specific condensed gluten-free cream of mushroom soup, but their classic version is still not safe.

Making a delicious homemade gluten-free version
For those who prefer to cook from scratch or want full control over their ingredients, a homemade gluten-free cream of mushroom soup is simple and superior in flavor. A gluten-free roux is the key, substituting wheat flour with a safe alternative like a gluten-free flour blend or rice flour.
Ingredients:
- 2 tbsp butter or olive oil
- 1 cup chopped mushrooms (cremini or white button)
- 1/2 cup chopped onion or shallot
- 1 clove garlic, minced
- 3 tbsp gluten-free all-purpose flour blend or rice flour
- 2 cups gluten-free chicken or vegetable broth
- 1 cup milk or dairy-free alternative (unsweetened almond or coconut milk)
- Salt and pepper to taste
Instructions:
- Sauté Aromatics: Melt butter or heat oil in a saucepan over medium heat. Sauté the chopped mushrooms, onion, and garlic until the vegetables are soft and the mushrooms are golden brown.
- Create the Roux: Sprinkle the gluten-free flour over the mushroom mixture and stir constantly for about one minute to toast the flour.
- Whisk in Liquids: Gradually whisk in the gluten-free broth and milk, ensuring there are no lumps.
- Simmer: Bring the soup to a simmer and cook for 5-10 minutes, stirring occasionally until it thickens to your desired consistency.
- Season and Serve: Season with salt and pepper. For a smoother soup, use an immersion blender to puree, or leave it chunky for texture.
