  • Yield: 6 servings 1x

Description

A rich, creamy, and comforting slow cooker cream of mushroom soup made with fresh mushrooms, onions, garlic, and herbs. Perfect for cozy nights or make-ahead meals.


Ingredients

Scale
  • 2 tablespoons olive oil
  • 1 ½ pounds white or cremini mushrooms, sliced
  • 1 large yellow onion, diced
  • 4 cloves garlic, minced
  • 4 cups vegetable broth
  • 1 teaspoon dried thyme or 1 tablespoon fresh thyme
  • Salt and pepper, to taste
  • 1 cup heavy cream
  • 2 tablespoons butter
  • 2 tablespoons all-purpose flour

Instructions

  1. Heat olive oil in a skillet over medium heat. Add mushrooms, onions, and garlic. Sauté for 8–10 minutes until browned and fragrant.
  2. Transfer mixture to the slow cooker. Add vegetable broth, thyme, salt, and pepper. Stir to combine.
  3. Cover and cook on low for 6–8 hours or high for 3–4 hours until mushrooms are tender.
  4. Use an immersion blender to blend part of the soup for a creamy texture while keeping some chunks.
  5. Stir in heavy cream and butter. Taste and adjust seasoning as needed.
  6. Serve hot, garnished with extra herbs or a swirl of cream.

Notes

  • For deeper flavor, use a mix of mushroom varieties like cremini and shiitake.
  • Blend fully for a smoother soup or partially for a chunky texture.
  • Soup can be made ahead and refrigerated for up to 4 days.
  • Freeze without the cream, then stir it in after reheating.
