As a health-conscious consumer, you might be wondering, "is cream of mushroom soup keto?" Most of us love the creamy and comforting flavor of this classic soup. It's a favorite for many, but if you are on a ketogenic diet, you must be cautious.

To make it short and clear, most store-bought cream of mushroom soups, like Campbell’s cream, are not keto-friendly. They are typically made with wheat flour, cornstarch, and other ingredients that add carbs to the soup. For example, a half-cup serving of Campbell's Cream of Mushroom Soup contains 13g net carbs.

One of the most amazing soups you can create is a keto cream of mushroom soup recipe. With fresh mushrooms, heavy cream, chicken broth, cream cheese, and a sprinkle of fresh thyme, you can create an amazing soup that the whole family will love. And the best part? You can make this delicious soup on medium heat in a large pot, or in an Instant Pot or slow cooker for a convenient slow cooker recipe.

How to Make Keto Cream of Mushroom Soup

To begin, you'll need to clean mushrooms (we suggest a combination of white button mushrooms, cremini mushrooms, and portobello mushrooms for depth of flavor).

Heat a bit of olive oil over medium heat in a large pot. Add the mushrooms and cook until they release their liquid and start to brown.

Next, you want to add in your chicken broth (or bone broth for added nutrition), cream cheese, and spices. We suggest a bit of garlic powder, black pepper, and fresh thyme for a classic flavor profile.

To thicken your soup, a bit of xanthan gum can be used as a substitute for wheat flour. Just mix a small amount with cold water before adding to the soup to prevent clumping.

Finally, add in the heavy cream, and let the soup simmer until it's heated through. For a creamy soup, use an immersion blender or a regular blender to puree half of the soup. Be sure to let it cool a bit before using a regular blender, as blending hot soup can be dangerous.

Keto Cream of Mushroom Soup


  • 1/2 cup (1 stick) unsalted butter
  • 1/2 cup chopped onion
  • 4 cups sliced mushrooms
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/2 cup heavy cream
  • 1/4 cup grated Parmesan cheese


  1. Melt the butter in a large saucepan over medium heat. Add the onion and mushrooms and cook until softened, about 5 minutes.
  2. Add the salt, pepper, and heavy cream and bring to a simmer. Reduce heat to low and simmer for 5 minutes, or until the soup has thickened.
  3. Stir in the Parmesan cheese and serve.

This recipe makes about 4 cups of soup. Each serving contains 3 grams of net carbs.

Here are some tips for making keto-friendly cream of mushroom soup:

  • Use unsalted butter to reduce the sodium content.
  • Use low-carb or no-carb alternatives to flour and cornstarch, such as almond flour or xanthan gum.
  • Use heavy cream instead of milk.
  • Add a small amount of grated Parmesan cheese to thicken the soup and add flavor.

With a few simple substitutions, you can enjoy a delicious and creamy cream of mushroom soup that is keto-friendly.

Customizing Your Keto Cream of Mushroom Soup

One of the best things about homemade soup is that you can easily adjust it to your personal taste. Feel free to experiment with different types of mushrooms, or add some other keto-friendly ingredients. Fresh herbs, parmesan cheese, or even a splash of white wine can all add a unique touch to your soup.

Also, remember that a homemade cream of mushroom soup recipe can be a perfect substitute for condensed cream of mushroom soup in other dishes. Try using it in a keto green bean casserole for a low carb version of this holiday favorite.

Frequently Asked Questions (FAQs)

1. Can I store the keto cream of mushroom soup for later use?

Yes, you can! Once it cools, store it in an airtight container in the fridge. It's a fantastic meal prep option and can be reheated in a saucepan over medium heat or in a microwave.
