Description

Slow Cooker Creamy Mushroom Soup is a rich, earthy, and comforting meal made with fresh mushrooms, onions, and herbs, slowly simmered to perfection and finished with heavy cream for that irresistible velvety texture. It’s an easy, hands-off recipe perfect for cozy nights, meal prep, or crowd-pleasing dinners.

Ingredients

1 ½ pounds fresh mushrooms (cremini, button, or mixed), sliced

1 medium onion, chopped

3 cloves garlic, minced

4 cups vegetable or chicken broth

1 cup heavy cream

2 tablespoons butter

2 tablespoons flour or 1 tablespoon cornstarch

1 teaspoon thyme (dried or fresh)

Salt and black pepper to taste

2 tablespoons chopped parsley (optional for garnish)

Instructions

1. Gently clean the mushrooms and slice them evenly. Chop the onion and mince the garlic.

2. In a skillet over medium heat, melt the butter and sauté the onion and garlic until translucent. Add mushrooms and sauté for 5–7 minutes to release their flavor.

3. Transfer the sautéed mix to the slow cooker. Pour in the broth, add thyme, salt, and pepper. Stir everything together.

4. Cover and cook on LOW for 6–8 hours or on HIGH for 3–4 hours, until mushrooms are tender.

5. In a bowl, whisk together the cream and flour or cornstarch until smooth. Stir into the soup 30 minutes before serving.

6. Let it cook uncovered on HIGH for the final 30 minutes to thicken.

7. Use an immersion blender if you prefer a smoother texture. Blend partially or fully depending on your preference.

8. Garnish with chopped parsley or an extra drizzle of cream, and serve warm.

Notes

For added depth, try mixing in a few shiitake or portobello mushrooms with the base variety.

To make the soup gluten-free, use cornstarch instead of flour when thickening.

Always blend carefully—don’t over-blend if you like mushroom chunks in your soup.
