Ingredients

• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 1.5 pounds fresh white button mushrooms, sliced (or a mix of cremini and shiitake for deeper flavor)
• 1 large yellow onion, finely chopped
• 2 cloves garlic, minced
• 4 cups vegetable broth (or chicken broth for a non-vegetarian option)
• 1 cup milk (whole milk recommended for creaminess)
• 1 cup heavy cream
• 1/2 cup peeled and diced potato (about 1 small potato)
• 1 tablespoon all-purpose flour
• 1 teaspoon fresh thyme leaves, chopped (plus more for garnish)
• 1/2 teaspoon salt, or to taste
• 1/4 teaspoon black pepper, or to taste
• Optional: A pinch of nutmeg
• Optional: Crusty bread or croutons for serving

Instructions

1. Prepare the Mushrooms: Begin by gently cleaning your mushrooms. Avoid washing them under running water, as they absorb moisture like sponges. Instead, use a damp paper towel or a soft brush to wipe away any dirt. Slice the mushrooms evenly. This preparation step is crucial for achieving the best texture and flavor in your soup.
2. Sauté Aromatics and Mushrooms: In a large heavy-bottomed pot or Dutch oven, melt the butter with the olive oil over medium heat. Add the chopped onion and cook until softened and translucent, about 5-7 minutes, stirring occasionally. Add the minced garlic and cook for another minute until fragrant, being careful not to burn it.
3. Brown the Mushrooms: Add the sliced mushrooms to the pot. Increase the heat to medium-high. Cook the mushrooms, stirring occasionally, until they release their liquid and then begin to brown, about 8-10 minutes. Browning the mushrooms is key to developing a deep, rich umami flavor that will be the backbone of your soup. Don’t rush this step; patience here pays off immensely in the final taste.
4. Build the Roux: Sprinkle the flour over the sautéed mushrooms and stir well, cooking for 1-2 minutes. This will create a roux that helps to thicken the soup and prevents the cream from curdling later. Ensure the flour is fully incorporated and cooked slightly to remove any raw flour taste.
5. Add Liquids and Potato:Gradually pour in the vegetable broth, stirring constantly to prevent lumps from forming. Add the diced potato and fresh thyme. Bring the mixture to a simmer, then reduce the heat to low, cover, and let it cook for 15-20 minutes, or until the potatoes are very tender. The potato helps to naturally thicken the soup and add to its creamy texture without relying solely on dairy.
6. Blend for Creaminess: Carefully transfer about two-thirds of the soup mixture to a blender (be cautious with hot liquids, filling the blender only halfway and holding the lid down firmly with a towel). Alternatively, use an immersion blender directly in the pot. Blend until completely smooth. If you prefer a soup with some texture, you can blend less or leave some mushroom pieces whole. Return the blended soup to the pot with the unblended portion.
7. Incorporate Dairy: Over low heat, stir in the milk and heavy cream. Cook for another 5-7 minutes, stirring gently, until the soup is heated through and slightly thickened. Do not bring the soup to a rolling boil after adding the cream, as this can cause it to curdle. A gentle simmer is all you need.
8. Season and Serve: Season the soup with salt, black pepper, and an optional pinch of nutmeg. Taste and adjust seasonings as needed. Serve hot, garnished with extra fresh thyme leaves, a swirl of cream, or homemade croutons. This soup is best enjoyed immediately for optimal flavor and texture.

Cooking Tips and Variations

To achieve the absolute best creamy mushroom soup, start with high-quality, fresh mushrooms. While white button mushrooms are excellent, a mix of cremini (baby bellas), shiitake, or even a few rehydrated dried porcini mushrooms can add incredible depth and complexity to the flavor profile. If using dried mushrooms, rehydrate them in warm water, then chop and add them with the fresh mushrooms, straining and reserving the soaking liquid to use as part of your broth for an extra umami boost. When sautéing the mushrooms, don’t overcrowd the pan; cook them in batches if necessary to ensure they brown rather than steam, which is crucial for developing their rich flavor. A good sear on the mushrooms makes all the difference.

For an even richer flavor, consider deglazing the pan after sautéing the mushrooms with a splash of dry white wine (like Chardonnay or Sauvignon Blanc) before adding the broth. Let it simmer for a minute or two to cook off the alcohol. This adds a subtle acidity and complexity that brightens the earthy notes of the mushrooms. If you’re looking for a vegan alternative, substitute the butter with olive oil, use a plant-based milk (like unsweetened cashew or almond milk), and a full-fat coconut milk or cashew cream instead of heavy cream. Ensure your broth is vegetable-based. The potato helps greatly in maintaining a creamy texture even without dairy. To prevent the cream from curdling, ensure your soup is at a gentle simmer, not a vigorous boil, when adding the dairy, and stir it in slowly. You can also temper the cream by whisking a small amount of the hot soup into the cream first, then slowly adding the warmed cream mixture back into the pot.

The consistency of your soup is a matter of personal preference. If you find your soup too thick, thin it out with a little extra broth or milk until it reaches your desired consistency. If it’s too thin, you can simmer it gently for a bit longer to reduce, or make a quick slurry with a teaspoon of cornstarch mixed with a tablespoon of cold water, then whisk it into the simmering soup and cook until thickened. For an added layer of flavor, a tiny pinch of freshly grated nutmeg can elevate the creaminess and complement the earthy mushrooms beautifully. Fresh herbs are also a fantastic addition; while thyme is classic, a sprinkle of fresh parsley or chives at the end can add a fresh, bright counterpoint to the richness. Always taste and adjust seasonings at the end, as the flavors will meld and intensify as the soup cooks.

Storage and Reheating

This creamy mushroom soup is wonderful for meal prepping or enjoying as leftovers. To store, allow the soup to cool completely to room temperature before transferring it to an airtight container. Refrigerate promptly, and it will keep well for up to 3-4 days. Proper cooling and storage are important to maintain both food safety and the quality of the soup.

When reheating, it’s best to do so gently to maintain the soup’s creamy texture. You can reheat individual portions in the microwave, stirring occasionally, until heated through. For larger quantities, reheat the soup in a saucepan over low to medium-low heat on the stovetop, stirring frequently. Avoid bringing it to a rapid boil, as high heat can sometimes cause the dairy components to separate or curdle. If the soup has thickened considerably in the refrigerator, you may want to add a splash of milk, cream, or broth while reheating to restore its original consistency and creaminess. Taste and adjust seasonings after reheating, as flavors can sometimes mellow or intensify.

Freezing creamy soups can sometimes be tricky due to the dairy content, which may separate upon thawing. However, if you wish to freeze this soup, it is generally best to freeze it before adding the heavy cream. Prepare the soup up to the point of blending and adding the milk (but not the heavy cream). Let it cool completely, then transfer to freezer-safe containers or bags, leaving some headspace for expansion. It can be frozen for up to 2-3 months. When ready to serve, thaw the soup overnight in the refrigerator, then reheat gently on the stovetop. Once it’s simmering and heated through, stir in the heavy cream and cook until warmed, then season to taste. If you do freeze the fully prepared soup with cream, it may still be enjoyable, but be prepared for a slightly altered texture upon thawing and reheating; an immersion blender can often help re-emulsify it.

Frequently Asked Questions

Can I make this soup ahead of time?

Absolutely! This creamy mushroom soup is an excellent make-ahead dish. In fact, the flavors often deepen and meld beautifully overnight, making it even more delicious the next day. Prepare the soup as directed, allow it to cool completely, then store it in an airtight container in the refrigerator for up to 3-4 days. Reheat gently on the stovetop or in the microwave, adding a splash of milk or broth if needed to adjust consistency.

What kind of mushrooms are best for this recipe?

While fresh white button mushrooms are perfectly delicious and readily available, you can enhance the depth of flavor by using a mix of mushrooms. Cremini (baby bella) mushrooms offer a richer, earthier taste. For a more gourmet touch, consider adding a few sliced shiitake mushrooms or rehydrated dried porcini mushrooms. The key is to use fresh, firm mushrooms and allow them to brown well during sautéing to develop their umami.

How can I make this soup thicker or thinner?

If your soup is too thick for your liking, simply whisk in a little extra warm vegetable broth or milk until it reaches your desired consistency. If it’s too thin, you have a few options: you can simmer it uncovered for a bit longer to allow some liquid to evaporate and reduce, or you can create a cornstarch slurry. To do this, mix 1 teaspoon of cornstarch with 1 tablespoon of cold water until smooth, then slowly whisk it into the simmering soup and cook for another 1-2 minutes until it thickens.

Can I make this soup dairy-free or vegan?

Yes, you can! To make this soup dairy-free and vegan, substitute the butter with olive oil, use a good quality vegetable broth, and replace the milk and heavy cream with plant-based alternatives. Unsweetened cashew milk or almond milk works well for the milk, and full-fat coconut milk (for a richer texture but with a subtle coconut flavor) or a homemade cashew cream (blended soaked cashews with water) can be used in place of the heavy cream. The potato in the recipe naturally aids in creating a creamy texture, making it easier to achieve a delicious dairy-free version.
