Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 30 minutes
• Total Time: 45 minutes
• Servings: 8
• Dietary Type: Vegetarian

Ingredients

• 4 tablespoons unsalted butter
• 2 leeks, white and light green parts only, halved lengthwise and thinly sliced
• 1 large onion, chopped
• 3 large portabella mushrooms, dark gills scraped out, mushrooms chopped
• 3 tablespoons all-purpose flour
• 1 1/2 teaspoons dried thyme leaves
• 1 bay leaf
• 6 cups low sodium chicken broth
• 1 teaspoon salt
• 1 teaspoon sugar
• 1/2 teaspoon pepper
• 1 cup heavy cream
• 1/4 cup chopped fresh parsley

Equipment Needed

• Large pot or Dutch oven
• Cutting board
• Chef’s knife
• Blender or food processor
• Measuring spoons and cups

Instructions

1. Begin by preparing your vegetables. Thoroughly wash the leeks, making sure to remove any dirt trapped between the layers. Halve them lengthwise and thinly slice the white and light green parts. Chop the onion into small, even pieces.
2. Next, prepare the portabella mushrooms. Using a spoon, gently scrape out the dark gills from the underside of each mushroom cap. This step is crucial for preventing a muddy color and slightly bitter taste in the finished soup. Once the gills are removed, chop the mushrooms into bite-sized pieces.
3. In a large pot or Dutch oven, melt the butter over medium heat. Add the sliced leeks and chopped onion. Sauté, stirring constantly, until the vegetables are tender, about 2-3 minutes. Be careful not to brown the leeks and onions; you want them to soften and become translucent.
4. Lower the heat to medium-low, add the chopped portabella mushrooms, and cook for about 10 minutes longer, covered, stirring occasionally. Covering the pot allows the mushrooms to release their moisture and soften, intensifying their flavor.
5. Raise the heat to medium and stir in the flour. Cook for 2-3 minutes, stirring constantly, to create a roux. This step is essential for thickening the soup and preventing it from being too thin. Ensure that the flour is fully incorporated and cooked through; otherwise, it can leave a raw taste in the soup.
6. Add the thyme, bay leaf, chicken broth, salt, sugar, and pepper. Stir well to combine all the ingredients. The sugar might seem like an odd addition, but it helps to balance the earthy flavors of the mushrooms and the savory taste of the broth.
7. Bring the soup to a simmer, then reduce the heat to low, partially cover the pot, and simmer for about 10 minutes. Simmering allows the flavors to meld and deepen, creating a richer, more complex soup.
8. Remove the soup from the heat and allow it to cool slightly. Discard the bay leaf before proceeding.
9. Carefully puree the soup in batches in a blender or food processor until smooth. Be extremely cautious when blending hot liquids, as the steam can cause pressure to build up and the lid to explode. It’s best to vent the lid slightly or use an immersion blender directly in the pot.
10. Return the pureed soup to the pan and add the heavy cream. Stir gently to combine.
11. Cook over low heat until just heated through, but do not boil. Boiling the soup after adding the cream can cause it to curdle.
12. Adjust the seasonings if necessary, adding more salt, pepper, or thyme to taste.
13. Serve hot, garnished with chopped fresh parsley.

Expert Tips & Tricks

• For a more intense mushroom flavor, consider using a combination of portabella and other wild mushrooms, such as cremini or shiitake.
• If you don’t have heavy cream on hand, you can substitute half-and-half or even whole milk, but the soup will be less rich and creamy.
• To make the soup ahead of time, prepare it through step 9, then cool completely and store in the refrigerator for up to 3 days. Add the cream and reheat before serving.
• If the soup is too thick after pureeing, add a little extra chicken broth or water to thin it out.
• For a vegan version, substitute the butter with olive oil or vegan butter, the chicken broth with vegetable broth, and the heavy cream with coconut cream or cashew cream.
• To deepen the flavor even further, try roasting the portabella mushrooms before chopping and adding them to the soup. This will bring out their natural sweetness and earthiness.

Serving & Storage Suggestions

Serve this creamy portabella mushroom soup hot, garnished with a sprinkle of fresh parsley for a pop of color and freshness. A swirl of cream or a dollop of sour cream can also add a touch of elegance. This soup pairs beautifully with crusty bread for dipping, a grilled cheese sandwich, or a simple green salad.

Leftover soup can be stored in an airtight container in the refrigerator for up to 3-4 days. For longer storage, freeze the soup in individual portions for up to 2-3 months. When reheating, thaw the soup in the refrigerator overnight and gently warm it on the stovetop over low heat. Avoid boiling to prevent the cream from separating.

FAQs (Frequently Asked Questions)

Q: Can I use different types of mushrooms for this soup?
A: Absolutely! While portabella mushrooms provide a rich, earthy flavor, you can substitute or combine them with other varieties such as cremini, shiitake, or oyster mushrooms for a more complex flavor profile.
