Mushroom Soup Recipe
Ingredients
To make this delicious low carb mushroom soup, you’ll need:
- Fresh Mushrooms: cremini mushrooms or white button mushrooms. I use a combination of both and an additional 2 handfuls of dried porcini mushrooms (optional).
- Broth: Use homemade chicken broth (chicken stock/bone broth) for extra flavor, or opt for store-bought (check ingredients for low-carb options). For a vegetarian version, use vegetable broth or water.
- Onion & Garlic: Add depth of flavor with chopped onion and garlic cloves.
- Heavy cream: creates a creamy soup base.
- Fat: Options include ghee, olive oil, or avocado oil.
- Fresh thyme or dried herbs
- Salt and black pepper: season to taste
Optional add-ins:
- Porcini mushrooms – add for an additional layer of flavor to the soup, just a handful or two.
- Nutmeg: enhance earthy notes.
- Butter: for a touch of richness and buttery flavor.
- Garlic powder: for extra garlicky flavor.

Equipment
For this recipe you’ll need these kitchen tools:
- Large saucepan
- Cutting board and knife
- Wooden spatula
- Immersion blender/stationary blender or food processor
- Ladle
Instructions
Step 1: Sauté onion and garlic
Begin by melting ghee (or chosen fat) in a large pot over medium heat. Add the diced onion and cook until softened and fragrant, roughly 5 minutes.
Stir in the minced garlic and cook for another 30 seconds, releasing its aroma.
Step 2: Add Mushrooms
Add the sliced mushrooms to the pot and increase the heat to medium-high. Cook for 30-40 minutes, stirring occasionally, until the mushrooms release their moisture and shrink significantly. This caramelization step builds rich flavor.
TIP: Set some of the mushrooms aside and use them as a garnish.
Meanwhile, prepare the garnish for the mushroom soup. In a pan saute the sliced reserved mushrooms with 1 teaspoon of ghee/olive oil until golden brown.
Step 3: Turning smooth
Sprinkle in the thyme, nutmeg, garlic powder, and porcini mushrooms, then pour in the chicken broth. Bring the soup to a boil. Reduce heat and simmer for 5-10 minutes, allowing the flavors to meld. Remove the pot from heat and use an immersion blender to puree the soup until smooth and creamy.
Step 4. Enrich the Soup
Stir in the heavy cream, butter and season with salt and pepper to taste. Return the pot to low heat and simmer gently, stirring frequently. Taste the soup and adjust the seasoning as needed. If you prefer a thinner consistency, add more broth or cream.

Toppings
