Ingredients
Scale
- 1 pound sliced mushrooms (brown, cremini or chanterelle, or a mix)
- 4 tablespoons butter, divided
- 1 small onion, finely chopped
- 1 leek (white and light green parts), chopped
- 2 garlic cloves, crushed
- 1 to 2 sprigs fresh thyme or 1 teaspoon dried thyme (optional)
- 1 tablespoon sherry cooking wine (optional)
- 4 cups low carb chicken stock
- 1 cup heavy whipping cream
- ½ teaspoon salt, or to taste
- ¼ teaspoon black pepper
Instructions
- Rinse and slice the mushrooms. Set aside.
- Finely chop the onion and leek.
- Melt 2 tablespoons of butter in a large pot or Dutch oven over medium-high heat.
- Add the onion and leek. Cook 4 to 5 minutes, until soft and translucent.
- Add the garlic and cook 1 minute, until fragrant.
- Add the mushrooms, the remaining 2 tablespoons of butter and the thyme. Cook 5 minutes, stirring often, until the mushrooms soften and release their juices.
- If using sherry, add it and cook 1 minute.
- Stir in the chicken stock. Bring to a simmer and cook 8 minutes.
- Stir in the heavy cream and cook 3 minutes more. Season with salt and pepper.
- Remove the thyme sprigs, if using. Blend with an immersion blender until smooth and creamy, or blend in batches in a regular blender. Leave it a little chunky if you like.
Notes
For casseroles: use 2 cups of chicken stock instead of 4, and simmer until it coats the back of a spoon. About 1¼ cups replaces one 10.5-ounce can of condensed soup.
Lighter version: use ½ cup cream instead of 1 cup.
Storage: refrigerate up to 4 days. To freeze, let it cool and freeze before adding the cream for up to 3 months, then stir the cream in when you reheat.
Blender safety: if using a regular blender, fill it only halfway and vent the lid, since hot soup expands.
