Low Carb Cream of Mushroom Soup Recipe

It’s unbelievable how easy this keto soup is to make. Only a few wholesome ingredients are needed to make a comforting bowl of soup in less than 30 minutes.

Low Carb Cream of Mushroom Soup Ingredients

This Low Carb soup needs just a few wholesome ingredients such as full-fat cream, your favorite mushrooms, a splash of white wine and to complement the flavors, add fresh thyme! Here are all the ingredients you’ll need

  • Fresh Mushrooms: I love to use fresh brown or cremini mushroom in this recipe. You can choose portobello mushrooms or a mushroom mix, and they will all result in a delicious soup. To save some time, get sliced mushrooms from the store.
  • Fresh Herbs: My favorite herbs to use in this gluten-free soup are thyme and parsley. If these aren’t your favorite, you can always switch and add: rosemary, oregano, chives, or cilantro
  • Cream: Stick to the full-fat heavy whipping cream because it’s less processed than light cream, half and half or thickened cream.
  • Garlic & Onions – These are two extremely important ingredients that create the perfect taste for this mushroom soup recipe.
  • Low Carb Thickener: We need a thickener to create this tasty creamy mushroom soup. For low carb options, you can use xanthan gum, glucomannan powder, arrowroot powder or coconut flour.
  • Wine: Use dry red or white wine to complement the flavors. You can leave it wine, but I highly suggest to use it – it will make a difference!

How to Make Low Carb Cream of Mushroom Soup

I used to buy canned mushroom soup for years and never thought about it. I enjoyed it for lunch or dinner and never thought of making it at home.

What a game-changer it is!

Not only we get rid of all those unnecessary ingredients like wheat flour, tons of added sugar, and a few more extra processed, but it is extremely easy to whip up. I’d say it’s a million times creamier and flavorful, if not even more!

  1. Infuse the butter and oil over medium heat with garlic, onion, and herbs. Then sautée the sliced mushrooms for a few minutes, so they soak up all that garlic butter flavor.
  2. Add white wine, broth, sprinkle with a thickener agent and simmer for about 15 minutes. Reduce the heat and add heavy cream.
  3. Optional: Puree the soup to get the desired consistency.
  4. Season with salt and pepper to taste and serve with a thick buttery slice of keto bread.

How to thicken Low Carb Cream of Mushrooms Soup Recipe?

This keto soup is indeed very creamy, but what about a thick mushroom soup? Usually, this soup is thickened with wheat flour, but to keep it low carb we have to think about substitutions that yield the same results.

  • Xanthan Gum – It has the same functions as gelatin but is entirely vegan. It can be used in tons of sweet or savory dishes. The best way to blend xanthan gum is to dissolve it in a bit of oil. As a rule of thumb use 1/8 tsp xanthan gum per cup of liquid and constantly whisk after adding it the sauce.
  • Glucomannan Powder (or konjac fiber) – It is ten times powerful than cornstarch and does not have calories. Use a tiny amount of konjac fiber mixed with cold water or stock until smooth, then add this mixture to the soup. Do not add konjac flour directly in the hot soup because it turns immediately into lumps. Always remember to dissolve it first in cold liquids, and it will thicken when heated to boiling temperature.
  • Coconut Flour – It’s great to use as a thickener since it has the amazing property of soaking liquids very well. It will add a slightly sweet coconut taste.
  • Arrowroot Powder – It’s gluten-free, grain-free, and paleo starchy substance extracted from the root of a tropical tuber. It does a great job replacing cornstarch because it has no taste and it’s twice as powerful as thicking soups and sauces than cornstarch. Use one teaspoon of arrowroot powder for every tablespoon of flour. For this recipe use 2 tsp of arrowroot powder and keep in mind that will add about 2g net carbs extra to each serving of soup
