Description

A creamy, comforting potato leek soup made effortlessly in the slow cooker—rich, smooth, and perfect for chilly days. This slow-cooked soup combines tender potatoes and fragrant leeks with a silky touch of milk or cream, delivering a warm and satisfying dish ideal for any season.


Ingredients

Soup Ingredients

  • 4 cups potatoes, peeled and diced
  • 2 leeks, sliced and cleaned
  • 4 cups vegetable or chicken broth
  • 2 tbsp butter
  • 1 tsp salt
  • 1/2 tsp black pepper

Finishing Ingredients

  • 1 cup milk or cream


Instructions

  1. Combine Ingredients: Add the peeled and diced potatoes, sliced and cleaned leeks, broth, butter, salt, and black pepper into the slow cooker, ensuring the ingredients are evenly distributed for consistent cooking.
  2. Slow Cook: Cover and cook the mixture on low for 6 to 7 hours or on high for 3 to 4 hours, allowing the potatoes and leeks to soften completely and the flavors to meld beautifully.
  3. Blend Soup: Using an immersion blender, carefully blend the contents of the slow cooker until the soup reaches a smooth and creamy consistency, ensuring no large chunks remain.
  4. Add Creaminess: Stir in the milk or cream into the blended soup, mixing thoroughly to incorporate and enrich the texture without overheating to prevent curdling.
  5. Season and Serve: Taste the soup and adjust the seasoning if necessary. Serve warm, optionally garnishing with chives or crispy bacon for added flavor and texture.
