Ingredients for Keto Creamy Mushroom Soup

- 400–500 g mushrooms (white button or cremini)
- 1 shallot or 1/2 small onion (or onion powder for lower carbs)
- 2 tbsp butter
- 1 tbsp olive oil
- 500 ml chicken or vegetable broth (unsweetened)
- 200 ml heavy cream (33%+)
- 2 garlic cloves
- 1/2 tsp thyme or Italian herbs
- Salt and pepper to taste
- Optional: 30 g grated Parmesan for serving
Instruction

- Sauté the mushrooms: Heat the butter and olive oil in a large pot over medium heat. Add the sliced mushrooms and cook for 7–10 minutes, stirring occasionally, until they release moisture and begin turning beautifully golden around the edges. Proper browning is essential — this step builds deep, savory flavor.
- Add aromatics: Stir in the chopped shallot (or onion) and minced garlic. Cook 2–3 minutes until softened and fragrant. If you prefer extra low-carb, substitute onion with 1/4 teaspoon of onion powder added later when blending.
- Deglaze with broth: Pour in the broth, scraping the bottom to release any caramelized bits. Increase heat slightly and bring the mixture to a gentle boil. Once boiling, cover the pot and reduce to a simmer for 10 minutes to allow flavors to blend.
- Blend to desired texture: Remove from heat. Use an immersion blender directly in the pot to puree the soup until silky smooth. For a chunkier soup, reserve a handful of mushrooms beforehand, blend the rest, then stir the pieces back in.
- Add cream and seasonings: Return the pot to low heat. Stir in the heavy cream, thyme or Italian herbs, salt, and black pepper. Warm gently for 2–3 minutes — do not boil, as high heat can cause the cream to separate.
- Final adjustments: Taste and adjust seasoning. Add more salt, herbs, or a splash of cream depending on your preference. If you want a thicker soup, simmer uncovered for 3 more minutes.
- Serve: Ladle the soup into bowls and finish with grated Parmesan, a drizzle of olive oil, or freshly cracked black pepper.
