Ingredients for Keto Mushroom Soup
You don’t need any fancy ingredients for this homemade soup. You might already have everything in your kitchen!
- 1/4 cup butter
- 6 cups mushrooms – chopped
- 1/2 cup onion – finely chopped
- 1 clove garlic – minced
- 3 cups chicken broth
- 2 cups heavy cream
- 1 4 ounce package of cream cheese
- 1/2 teaspoon fresh thyme
- 1/2 teaspoon salt
- 1/2 teaspoon pepper

How to Make Cream of Mushroom Soup
This mushroom soup is ready for you in about 35 minutes, most of that time is just the soup simmering on the stove.
Add chicken broth, heavy cream, cream cheese, thyme, salt and pepper. You can use boxed chicken broth or you can use bouillon cubes and water. I use bouillon because it saves me money. Stir so it’s all combined.
Bring the soup to a boil and then reduce heat and simmer for 25 minutes, stirring occasionally.
Now this is important. Remove half of the soup from the pot and place in a bowl. Careful, the soup is hot! With the soup remaining in the pot, use a immersion blender to blend until smooth. Now add the soup that’s in the bowl back into the pot. Simmer for 10 more minutes.
Why do we use a immersion blender? We want the soup to be creamy and really have a mushroom taste to it. By using the immersion blender, we’re helping the soup achieve a high mushroom flavor and thicken up into a creamy soup. If you don’t have a immersion blender, you can use a blender. But again, please be careful – it’s hot!
Now the best part – time to serve in bowls! It’s Mushroom Soup Time! Totally optional, but I like a little dash of paprika on top!
