The Problem with Canned Cream of Mushroom Soup
Traditional condensed cream of mushroom soup, the kind found in the red-and-white can, is a staple in many classic casserole recipes. However, for anyone following a ketogenic diet, this convenience comes at a high caloric and carbohydrate price. The primary reason canned versions are not keto-friendly is their use of high-carb thickening agents, namely wheat flour and modified cornstarch. These ingredients contribute a significant amount of carbohydrates per serving, which can quickly push an individual over their daily carb limit and disrupt ketosis.
Why Canned Soups Don't Fit the Keto Diet
- High-Carb Thickeners: The roux (a mixture of fat and flour) used in canned soups is a major source of carbohydrates, which are precisely what the keto diet aims to minimize.
- Questionable Ingredients: Canned soups often contain other non-keto additives, such as vegetable oils, MSG, and hidden sugars, to enhance flavor and shelf life.
- Higher Overall Carb Count: Even "cleaner" or organic canned soups may use alternative thickeners that still raise the total carb count, making label-reading crucial.
How to Make a Keto-Friendly Cream of Mushroom Soup
Fortunately, it's simple to create a delicious, rich, and creamy mushroom soup at home that is entirely keto-compliant. The key is to replace the high-carb thickeners with low-carb alternatives. Instead of flour, many recipes use the natural thickening power of heavy cream, cream cheese, or a tiny amount of a keto-friendly thickener like xanthan gum. This homemade approach gives you complete control over the ingredients, ensuring a meal that is both flavorful and true to your dietary goals.
Keto Cream of Mushroom Recipe: Simple and Delicious
This easy recipe can be used as a standalone soup or a replacement for canned versions in your favorite casseroles.
Ingredients
- 4 tbsp butter
- 1 pound mixed mushrooms (cremini and button work well), sliced
- 1 small onion, finely chopped
- 3 cloves garlic, minced
- 4 cups chicken or vegetable broth
- 1 cup heavy cream
- 1 tbsp fresh thyme leaves
- 1/2 tsp xanthan gum (optional, for extra thickness)
- Salt and black pepper to taste
Instructions
- Melt the butter in a large pot or Dutch oven over medium heat.
- Add the sliced mushrooms and onions. Sauté for 10-15 minutes until the mushrooms release their liquid and begin to brown.
- Stir in the minced garlic and cook for another minute until fragrant.
- Pour in the broth and fresh thyme, bringing the mixture to a simmer.
- Reduce heat and simmer for 15 minutes to allow the flavors to meld.
- Remove the pot from the heat. Stir in the heavy cream.
- To thicken, you can either use an immersion blender to puree some or all of the soup or, for a smoother consistency, slowly whisk in the optional xanthan gum. (Note: A little xanthan gum goes a long way and thickens as it sits.)
- Season with salt and pepper to taste before serving.

Benefits of Going Homemade
Beyond the favorable carb count, preparing your own cream of mushroom soup offers several other benefits for your keto lifestyle:

- Superior Flavor: The taste of fresh mushrooms and quality ingredients like heavy cream and real butter is far superior to the processed flavor of canned soup.
- Dietary Control: For those with allergies or sensitivities to dairy or other ingredients, homemade allows for easy modifications, such as a dairy-free version.
- Versatility: A batch of homemade keto cream of mushroom soup can be used as a flavorful base for casseroles, a creamy sauce for meats, or enjoyed on its own as a satisfying meal.
