How To Make Keto Cream Of Mushroom Soup Recipe

Our cream of mushroom soup is easy and one of the most flavorful soups I have ever made. Once you make this recipe, you will definitely agree with me.

Kitchen Gadgets Needed:

  • Cooking Pot: A sturdy and large pot is needed for this recipe. 
  • Bowls: Use to prepare each of the ingredients required.

Ingredients Needed:

  • Butter: compared to oil, butter gives you that extra flavor you would not expect.
  • Onion: Choose fresh white onions for the soup. If you prefer a milder flavor, shallots can be used.
  • Mushrooms: For the mushrooms, choose your favorite variety of mushrooms, such as button, cremini, or shiitake. Fresh mushrooms provide the best flavor, but canned mushrooms can also be used.
  • Broth: You can use homemade broth or vegetable or chicken broth.
  • Heavy Cream: To give our soup perfect creaminess.
  • Salt and Pepper: Should be added to every savory recipe.
  • Xanthan Gum: It is optional to thicken the soup without adding extra carbs.

TIPS FOR MAKING LOW CARB CREAM OF MUSHROOM SOUP:

  • Mushroom Variety: Mix different mushroom types like cremini, shiitake, or portobello for a richer flavor. Sauté them first to bring out their natural, earthy taste.
  • Creamy Texture: Use heavy or coconut cream for a smooth, rich texture. Add it slowly to control how thick and creamy you want the soup to be.
  • Seasoning Boost: Add a dash of garlic, onion powder, or even a splash of Worcestershire sauce for extra depth in flavor.
  • Thickening Without Flour: Instead of flour, blend a portion of the cooked mushrooms with broth to naturally thicken the soup. This trick keeps it low carb and adds to the creaminess.
  • Garnish: Add crispy bacon bits, fresh thyme or fried mushroom slices on top for a delicious crunch and a gourmet touch.

FREQUENTLY ASKED QUESTIONS AND ANSWERS

Is This Better Than The Canned Mushroom Soup?

Well, any homemade food is better than the canned or store-bought ones. I have tried eating canned soup once, and I can say that it is ok, but nothing will beat the one you made and customized. 

What To Serve With Keto Soup Recipe?

Any soup is perfectly paired with bread, so I suggest making your own farmer’s bread or Italian breadsticks at home and serving it with this creamy mushroom soup. Pair it with your fresh green bean casserole for a savory veggie meal. 

If you like pairing your creamy soups with bite-sized snacks, try fried onions or garlic croutons. These crunchy snacks are perfect for the soup. Top the soup with dehydrated mushrooms.
