Ingredients Needed
To make the Longwood Gardens Cream of Mushroom Soup, here’s what you’ll need:
- Mushrooms (preferably a mix of cremini, shiitake, and button mushrooms) – about 1 lb
- Unsalted Butter – 4 tablespoons
- Yellow Onion – 1 medium, finely chopped
- Garlic Cloves – 3, minced
- All-Purpose Flour – 3 tablespoons (for thickening)
- Vegetable Broth – 4 cups (can substitute with chicken broth)
- Heavy Cream – 1 cup (for a rich, velvety texture)
- Thyme – 2 teaspoons, fresh
- Bay Leaves – 1 or 2
- Salt and Pepper – to taste
- Chopped Parsley – for garnish
- Lemon Juice – 1 teaspoon (optional, for brightness)
These ingredients combine to create the perfect balance of flavors that make this soup irresistible. The use of a variety of mushrooms is key, as it provides depth and complexity to the flavor profile.
Cooking Instructions
Now that you have everything ready, here’s how to bring it all together:
- Prepare the Mushrooms: Clean the mushrooms with a damp cloth or paper towel to remove any dirt. Slice them thinly, as they will cook down and release their moisture quickly.
- Sauté the Aromatics: In a large pot, melt the butter over medium heat. Add the chopped onions and sauté them until translucent, about 5 minutes. Add the garlic and cook for another 30 seconds, being careful not to burn it.
- Cook the Mushrooms: Add the sliced mushrooms to the pot. Stir occasionally and let them cook for about 8-10 minutes, until they soften and begin to release their moisture. The mushrooms will shrink down significantly as they cook.
- Create the Roux: Sprinkle the flour over the cooked mushrooms, and stir to coat evenly. This will create a thickening base for the soup. Let the flour cook for about 2 minutes, stirring constantly.
- Add the Broth: Gradually pour in the vegetable broth while stirring to avoid lumps. Bring the mixture to a simmer, and let it cook for about 15 minutes, allowing the flavors to meld together.
- Blend the Soup: Remove the soup from the heat and carefully use an immersion blender to purée the soup until smooth. If you don’t have an immersion blender, you can transfer the soup in batches to a traditional blender, but be cautious of hot splashes.
- Finish with Cream: Return the blended soup to the heat. Stir in the heavy cream, thyme, and bay leaves. Let the soup simmer for an additional 5-7 minutes, allowing the cream to blend in and the herbs to infuse their flavors.
- Season: Taste the soup and adjust the seasoning with salt and pepper. For a slight tanginess, you can add a teaspoon of lemon juice.
- Serve and Garnish: Ladle the soup into bowls, sprinkle with freshly chopped parsley, and serve hot.
Ingredient Insights
Every ingredient in this recipe plays a vital role in creating the perfect bowl of cream of mushroom soup. Here’s why each one is important:
- Mushrooms: The star of the show! A mix of different mushrooms-like cremini, shiitake, and button mushrooms-provides layers of flavor. Cremini mushrooms offer a mild, earthy taste, while shiitake mushrooms add a deeper umami, and button mushrooms keep the base light and subtle.
- Butter: Adds richness and helps sauté the onions and garlic, giving a base layer of flavor. Using unsalted butter allows you to control the salt level in the soup more effectively.
- Heavy Cream: This is what gives the soup its luxurious, smooth texture. It makes the soup rich and indulgent, complementing the mushrooms perfectly.
- Thyme and Bay Leaves: These herbs infuse the soup with an aromatic depth, creating a savory background that doesn’t overpower the mushrooms.
Expert Tips
- Use fresh mushrooms whenever possible. The fresher the mushrooms, the better the soup will taste. Avoid using pre-sliced mushrooms as they often lose their flavor more quickly.
- Don’t rush the sautéing process. Taking your time to cook the mushrooms until they release all their moisture allows them to develop a deeper flavor.
- For a smoother texture, you can strain the soup after blending to remove any remaining pieces of mushroom, but this is totally optional.
- Make it ahead of time! This soup actually tastes better the next day once the flavors have had time to meld. Store it in an airtight container in the fridge for up to 3 days.
- Vegan option: To make this soup dairy-free, use coconut cream instead of heavy cream, and substitute vegetable broth for the butter by using olive oil or vegan butter.
Recipe Variations
This classic recipe can easily be adapted to suit your preferences or dietary needs. Here are a few variations you can try:
- Vegan/Vegetarian Version: As mentioned earlier, substitute the heavy cream with coconut cream or cashew cream and use plant-based butter or oil in place of the unsalted butter. Ensure the broth is vegetable-based.
- Add Protein: If you’re looking to make this a more hearty meal, you can add diced chicken breast, turkey, or even crispy bacon bits as a topping for extra flavor.
- Spicy Kick: For a little heat, sprinkle some red pepper flakes into the soup while it simmers. Alternatively, you could add a touch of smoked paprika for a smoky flavor.
- Herb Twist: Try adding a bay leaf or two, or even a sprig of rosemary, during the simmering process to give the soup a more complex herbal flavor. Remove the rosemary sprig before serving, though!
- Mushroom Variety: While the traditional combination of cremini, shiitake, and button mushrooms is a classic, feel free to experiment with other types of mushrooms like oyster, portobello, or even more exotic varieties like maitake.
