Description

This slow cooker creamy mushroom soup is rich, comforting, and deeply flavorful, made with cremini mushrooms, herbs, and a splash of cream. It’s an easy, cozy meal perfect for chilly days and reheats beautifully for leftovers.


Ingredients

  • 2 tablespoons olive oil
  • 2 pounds cremini mushrooms, cleaned and sliced
  • 1 medium yellow onion, finely diced
  • 4 cloves garlic, minced
  • 3 tablespoons all-purpose flour
  • 4 cups low-sodium vegetable broth
  • 1 cup low-sodium chicken broth
  • 1 teaspoon sea salt
  • 1/2 teaspoon ground black pepper
  • 1 teaspoon dried thyme
  • 1/2 teaspoon dried rosemary
  • 1 bay leaf
  • 1 cup unsweetened plain almond milk
  • 1/2 cup heavy cream
  • 2 tablespoons fresh parsley, finely chopped

Instructions

  1. Heat olive oil in a skillet over medium heat.
  2. Sauté onion for 4 minutes until softened, then add garlic and cook for 30 seconds.
  3. Add mushrooms and cook 6–8 minutes until browned and moisture is released.
  4. Stir in flour and cook for 1 minute to remove raw taste.
  5. Transfer mixture to the slow cooker. Add vegetable broth, chicken broth, salt, pepper, thyme, rosemary, and bay leaf. Stir to combine.
  6. Cover and cook on low for 6–7 hours or high for 3–4 hours.
  7. Remove bay leaf. Blend soup with an immersion blender until smooth or to desired texture.
  8. Stir in almond milk and heavy cream. Cover and cook an additional 15–20 minutes.
  9. Taste and adjust seasoning. Garnish with fresh parsley and serve.

Notes

  • For dairy-free, replace heavy cream with full-fat coconut milk or additional almond milk.
  • Add a splash of soy sauce for extra umami depth.
  • Blend partially for a chunkier texture if preferred.
  • Stir in baby spinach at the end for added greens.
