Recommended Equipment
For this soup recipe, you will need kitchen utensils with measuring cups and spoons, a sharp kitchen knife, saucepan, blender, wooden cutting board, and a good Dutch oven like this cast iron pot.
Step-by-Step Instructions
Step One – Prepare the Cashew Cream
Begin by making the cashew cream. When it comes to cashew cream, you really should use a high-powered blender as it is the only type of blender that can make a smooth cream.
Add all the ingredients for the cashew cream to the blender and blend for about 30 seconds until you have a smooth cream. It should be the consistency of heavy cream. Set aside.
Pro Tip: If you don't have a high-powered blender, you can soak the cashews for about 6 hours ahead of time and they will blend up fairly well. For a nut-free version, feel free to use unsweetened non-dairy milk or coconut milk.
Step Two – Chop and Sauté
Next, chop the mushrooms, onions, herbs, and garlic. Heat some oil in a large pot and add the onion and sauté for three to four minutes on medium-high heat until the onions are fragrant and golden.
Pro Tip: Be sure to stir the onions often so they do not burn.
Lower the heat to medium and add the garlic and rosemary or thyme and sauté the veggies for another two minutes.
Add the chopped mushrooms, salt, and pepper to the pot. Sauté the mushrooms for 10-12 minutes while stirring occasionally until the mushrooms have released all of their moisture.
Next, add the vegetable broth to the pot and cook the mushroom mixture until it boils. Remove the mixture from the heat and allow the soup to cool before blending.
Step Three – Purée the Soup
Using a blender or food processor, blend the mushroom soup until smooth. Alternatively, you can use an immersion blender. However, the soup might not be completely smooth.
Pro Tip: Be careful while blending hot soups as the liquids can splatter. Be sure to allow the soup to cool and practice caution while blending hot liquids. You may need to blend in batches
Once the soup is creamy and smooth, transfer it back to the soup pot
Step Four – Stir in Cashew Cream
Finally, stir the prepared cashew cream into the smooth soup. Gently reheat the soup to desired heat before removing it from heat. Taste and adjust the salt and pepper if you need to.
Top with freshly chopped herbs and serve with toasted bread or croutons.
Serving and Storing
Serving – Serve this soup alongside dinner salads and hearty bread. This soup makes the perfect appetizer or side.
Storing – Store the leftover mushrooms soup in the refrigerator in an airtight container for up to four days. You can also freeze this soup. To freeze, transfer the leftovers in a freezer-safe bag or container and freeze for four months. To reheat, let thaw in the refrigerator overnight before gently reheating on the stovetop.
Tips and Tricks
- Be sure to constantly stir the onions and mushrooms while they cook to prevent them from sticking to the Dutch oven.
- Feel free to add different seasonings like garlic or onion powder or mushroom salt.
- Prepare this soup ahead of time and store in the refrigerator until ready to use. When ready to enjoy this soup again, simply reheat it in the microwave or on the stovetop until fully warm.
- Instead of cashew cream, use unsweetened coconut milk.
- You may need to add additional liquid like vegetable broth or water to thin the soup if it is too thick.
Frequently Asked Questions
No! Campbell's mushroom soup is not vegan so be sure to avoid it. Most of the cream-based soups by Campbell's contain dairy which is not suitable for the vegan lifestyle.
Yes, be sure to use unsweetened, and unflavored almond milk to keep things savory. You can also use different types of milk like soy, oat, or macadamia nut. However, these milks won't be as creamy as cashew cream.
Many kinds of fresh mushroom should work. I recommend cremini, baby bella, porcini, or button.
