Keto Cream of Mushroom Soup

Salads and soups are the best options for becoming a real dieter. Whether soups are made with vegetables and meat or the salads are with fruits, olives, or mushrooms, all versions are irresistible.

You can make many soups at home with easily available ingredients in a few hours. 

However, the soups are healthy for your body with essential nutrients and are a complete diet without fat. So they must be a part of your keto-friendly diet. 

What You Will Need

  • Mushrooms: Whether it’s a white button, crimini, or the hearty portobello, fresh mushrooms are essential for an authentic taste.
  • Onion Powder: I prefer adding onion powder because it has fewer carbs, but you can also use fresh diced onions for added flavor and taste.
  • Butter: Using high-quality unsalted butter adds a tasty flavor to the mushrooms while you saute them.
  • Garlic Powder: Adding garlic powder is the best option in creamy mushroom soup, but you can also go for a clove of minced fresh garlic for less flavor.
  • Chicken Broth: A bit of this helps lift the fond from the pan. Vegetable broth is an alternative, but avoid beef broth to maintain the mushroom’s flavor profile.
  • Heavy Cream: The key to our soup’s creamy texture. This ingredient transforms the soup into a velvety delight.

How to Make Keto Cream of Mushroom Soup
  1. Mushroom Magic: Begin by melting butter in a skillet set over medium heat. As it froths and sizzles, toss in the mushrooms. Cook them for about 10-15 minutes, allowing them to release their moisture and intensify in flavor.
  2. Flavor Build: With the mushrooms reduced, sprinkle in onion powder, garlic powder, a touch of salt and pepper, and then pour in the chicken broth. Stir everything, ensuring you scrape up those flavorful browned bits from the skillet’s base. Let this amalgamation cook for another 5 minutes. Now, carefully remove roughly a third of the mushrooms and set them aside – they’ll be back!
  3. Creamy Transformation: Pour the luxuriously thick heavy cream into the skillet. With an immersion blender in hand, blend the mixture. Aim for a smooth texture, but leaving a few mushroom pieces for texture is just perfect. Once blended, reintroduce the mushrooms you’d set aside.
  4. The Final Simmer: Let your soup bubble away gently for another 15-20 minutes. It will thicken to a rich consistency that’s reminiscent of wet oatmeal, signifying it’s ready to be savored.

Generally, mushroom soup is made with condensed cream by cooking all the ingredients with the roux made of flour and butter, which helps make a thick and smooth soup. 

It is undoubtedly a keto version of the soup without high carbs and starches. Instead of making the thick texture by adding artificial elements, we use heavy cream that is completely nutritious, then add a puree component of mushrooms.
