Before you start

Before starting, ensure your slow cooker is clean and the insert is properly seated. Take the time to properly wash and slice your mushrooms into uniform pieces. Chop the onion finely so that it integrates seamlessly into the soup as it cooks.

Have your spices measured out and your liquids ready to whisk. Clearing your workspace will make the process of layering the ingredients into the slow cooker much more efficient and enjoyable.

Ingredients at a glance (6)
  • 1 1/2 lbs white mushrooms, sliced
  • 1 medium onion, chopped
  • 2 tbsp paprika
  • 1 tsp dried dill
  • 2 cups vegetable broth
  • 1 can (10.5 oz) condensed cream of mushroom soup

Instructions

Layering the ingredients

  1. Prepare the base
    Place the sliced white mushrooms into the base of the slow cooker. Add the chopped onion over the mushrooms, spreading them out evenly across the insert.
    Look for Mushrooms should be evenly distributed at the bottom.
    Tip Ensure your mushrooms are cleaned well before slicing to remove any grit.

The base of the slow cooker should be neatly filled with the sliced mushrooms and onions, creating a stable foundation for the liquid ingredients.

Ensure the mushrooms are not packed too tightly, allowing the heat to circulate around them during the initial stages of the slow cooking process.

Adding liquids and seasoning

  1. Season and combine
    Sprinkle the paprika and dried dill over the vegetables. In a separate bowl, whisk together the vegetable broth and the condensed cream of mushroom soup until smooth, then pour this mixture into the slow cooker over the mushrooms and onions.
    Look for The broth mixture should be fully combined and poured evenly.
    Tip Whisking the condensed soup with the broth before adding ensures a smooth, lump-free texture.

The mixture should appear smooth and well-incorporated after whisking the broth and condensed soup together. The paprika and dill should be distributed evenly over the vegetables, ensuring that the seasonings are ready to infuse the soup as it begins to warm and simmer in the slow cooker.

Slow simmering

  1. Slow cook and finish
    Cover the slow cooker with the lid and cook on low for 4 hours, or until the mushrooms are tender and the soup is hot and fragrant.
    Look for Soup should be bubbling gently and mushrooms should be soft.
    Tip Stir the soup well before serving to ensure the flavors are perfectly incorporated.

At the end of the cooking time, the soup should look rich and velvety. The mushrooms should be soft and tender, and the broth should have a deep, inviting color from the paprika. Stir the soup thoroughly to ensure the cream base is perfectly uniform before serving.

Common mistakes

Avoid adding too much liquid at the beginning, as the mushrooms will release a significant amount of water during the slow cooking process. Adding too much broth will result in a thin, watery soup rather than the desired creamy consistency.

Also, ensure the paprika is mixed well; if it clumps, it can create pockets of intense, dusty spice rather than evenly flavoring the entire pot. Finally, do not lift the lid repeatedly, as this releases heat and extends the required cooking time.

How to tell it’s done

The soup is done when the mushrooms have reached a tender, yielding texture and the broth has thickened into a creamy, cohesive consistency. The onion should be translucent and soft, and the entire mixture should be heated through with a fragrant, earthy aroma.

There is no protein to monitor for temperature, so simply ensure the soup is steaming hot and the flavors have melded together perfectly after the four-hour cooking cycle.
