Ingredients

1.5 lbs mixed mushrooms (cremini, button, shiitake, oyster), sliced

1 medium yellow onion, finely chopped

4 garlic cloves, minced

4 cups vegetable broth

1 cup heavy cream or full-fat coconut milk

2 tablespoons unsalted butter or olive oil

2 teaspoons fresh thyme leaves or 1 teaspoon dried

1 teaspoon salt

0.5 teaspoon freshly ground black pepper

0.25 teaspoon crushed red pepper flakes (optional)

2 tablespoons all-purpose flour or gluten-free flour

Fresh parsley or chives, chopped (for garnish)


Instructions

1. Clean and slice mushrooms using a damp cloth or soft brush. Finely chop onion and mince garlic. Optional: sauté half the mushrooms, garlic, and onion in butter or oil for 5–7 minutes for extra flavor.

2. Add all mushrooms, garlic, onion, thyme, salt, pepper, red pepper flakes, and vegetable broth to your slow cooker. Stir well.

3. Cook on LOW for 6–7 hours or HIGH for 3–4 hours, without lifting the lid too often.

4. Mix flour with some hot broth to form a slurry. Add it to the slow cooker about 30 minutes before the end to thicken the soup.

5. Use an immersion blender to purée the soup to your desired texture. Blend all or just half.

6. Stir in cream or coconut milk. Mix well and heat for another 5–10 minutes.

7. Serve hot with a garnish of parsley or sautéed mushrooms, and some crusty bread on the side.


Notes

Use a mix of mushroom types for deeper, more complex flavor.

Always add cream at the end to avoid curdling.

For a gluten-free version, use GF flour or skip the thickener step and blend more.
