Creamy Wild Rice and Mushroom Soup

This hearty vegetarian soup combines earthy wild rice with savory mushrooms for a filling and nutritious meal. It is an excellent choice for a cozy dinner and pairs perfectly with crusty bread.

List of ingredients

• 2 Tbsp. olive oil – provides a high smoke point for sautéing.
• 2 Tbsp. unsalted butter – adds richness and a classic flavor base.
• 1 yellow onion, finely chopped – serves as a primary aromatic.
• 3/4 cup finely chopped carrots – adds sweetness and color.
• 1/2 cup finely chopped celery – provides a subtle savory note.
• 8 oz. baby bella (cremini) mushrooms, sliced – offers a meaty texture and umami flavor.
• 4 garlic cloves, minced – adds pungent, aromatic depth.
• 1 cup dry wild rice blend (such as Lundberg brand) – provides a nutty flavor and chewy texture.
• 1 Tbsp. poultry seasoning (or Herbs de Provence) – a blend of thyme, sage, and rosemary.
• 1 tsp. kosher salt – enhances all other flavors.
• 1/2 tsp. black pepper – adds a mild spicy kick.
• 4 cups (1 quart) lower sodium vegetable broth – the liquid base for the soup.
• 2/3 cup heavy cream (or cashew cream) – creates a thick, creamy consistency.
• 1/3 cup finely grated Parmesan cheese – adds a salty, nutty finish.

step-by-step instructions

1. Prepare the cream: Measure out your heavy cream and let it sit at room temperature while the soup cooks. If using cashew cream, soak 1/3 cup raw cashews in 2/3 cup boiling water for 30 minutes, then blend until smooth.
2. Sauté aromatics: Heat the olive oil and unsalted butter in a large stockpot or Dutch oven over medium-high heat. Once the fat is hot, add the chopped onion, carrots, and celery, cooking for 8 minutes until they have softened.
3. Cook mushrooms: Stir in the sliced baby bella mushrooms and minced garlic. Cook for 6 to 8 minutes, stirring only occasionally, until the mushrooms are soft and turn a slight golden brown.
4. Toast the rice: Add the dry wild rice blend to the pot and stir to coat the grains in oil. Let the rice cook for 1 to 2 minutes to lightly toast it, then stir in the poultry seasoning, salt, and black pepper.
5. Simmer the soup: Pour in the vegetable broth and 1 cup of water, stirring well to combine. Bring the mixture to a low boil, cover with a lid, reduce heat to medium-low, and simmer for 45 to 60 minutes until the rice is tender.
6. Finish with cream and cheese: Remove the lid and stir in the heavy cream or prepared cashew cream. Gradually sprinkle in the grated Parmesan cheese while stirring continuously to prevent clumping. Remove from heat immediately and ladle into bowls.

Optimizing Your Rice Selection

Choosing the Right Wild Rice Blend

Wild rice is actually a semi-aquatic grass rather than a true grain. Using a high-quality blend, such as one from Lundberg, ensures a consistent texture and deep nutty flavor. Avoid using only white rice as it will become too mushy during the long simmering process.

The Importance of Toasting Grains

Toasting the wild rice for 1 to 2 minutes before adding liquid helps lock in the nutty flavor. This step prevents the grains from breaking down too quickly and ensures they maintain a pleasant chew. It also creates a more complex flavor profile in the finished broth.

Adjusting for Pre-Cooked Rice

If you are using pre-cooked wild rice, omit the simmering step of 45 to 60 minutes. Instead, add the cooked rice at the very end when you stir in the cream. This prevents the rice from overcooking and turning the soup into a porridge.

Mushroom Variety and Preparation

Benefits of Baby Bella Mushrooms

Baby bella, or cremini, mushrooms are preferred because they have a stronger umami flavor than white button mushrooms. They hold their shape well during the simmering process, providing a meaty contrast to the rice. Ensure they are sliced evenly for uniform cooking.

Using a Mixed Mushroom Blend

For a more complex earthy taste, you can substitute a portion of the cremini mushrooms with shiitakes or oyster mushrooms. Shiitakes add a woody depth, while oyster mushrooms provide a softer texture. Avoid using only white button mushrooms as they lack the necessary depth for this recipe.

Proper Mushroom Cleaning Techniques

Avoid soaking mushrooms in water as they act like sponges and will become watery. Instead, wipe them clean with a damp paper towel or a soft brush. This ensures the mushrooms brown properly when sautéed rather than steaming in the pot.

Dairy-Free and Vegan Alternatives

How to Make Homemade Cashew Cream

To create a vegan alternative to heavy cream, soak 1/3 cup raw cashews in 2/3 cup boiling water for at least 30 minutes. Transfer the soaked cashews and the soaking liquid to a high-power blender and process until completely smooth. This provides a rich, creamy texture without any dairy.

Substituting for Parmesan Cheese

If you need a dairy-free cheese option, use a store-bought vegan Parmesan or a blend of nutritional yeast and ground cashews. Nutritional yeast provides the salty, cheesy flavor profile required to balance the earthy rice and mushrooms. Stir it in slowly to ensure it integrates well.

Using Coconut Milk as a Base

Full-fat coconut milk can replace heavy cream for a dairy-free version, though it will add a slight coconut flavor. To mitigate this, ensure you use a high-quality vegetable broth and plenty of poultry seasoning. Shake the can well before measuring to combine the fats.

Pro Tips for Better Flavor

Developing a Deep Mirepoix

The combination of onion, carrots, and celery is known as a mirepoix and is the foundation of the soup. Sautéing these for a full 8 minutes allows the natural sugars to release, which adds sweetness to the broth. Do not rush this step or the soup may taste raw.

Enhancing the Umami Profile

To increase the savoriness, ensure the mushrooms are browned properly before adding the rice. The golden-brown edges created by the Maillard reaction are essential for a rich taste. Stirring too frequently can release too much moisture and prevent this browning.

Balancing Salt and Seasoning

Use low-sodium vegetable broth to maintain control over the salt levels. Taste the soup after the rice has simmered but before adding the Parmesan cheese. Since Parmesan is naturally salty, you may need to adjust the final seasoning based on the brand of cheese used.

Serving and Pairing Suggestions

The Best Breads for Dipping

A crusty French baguette or a sourdough loaf is ideal for soaking up the creamy broth. Toasting the bread with a bit of olive oil and garlic creates a complementary flavor profile. Homemade croutons made from day-old bread also add a nice crunch.

Complementary Side Salads

A fresh, acidic salad balances the richness of the cream and cheese. A shredded Brussels sprout salad or a winter greens salad with a white balsamic vinaigrette works well. The acidity of the dressing cuts through the heavy texture of the soup.

Adding Fresh Garnishes

Garnish the bowls with freshly chopped parsley or chives to add a pop of color and brightness. A crack of fresh black pepper on top enhances the earthy tones. A small drizzle of truffle oil can also elevate the mushroom flavor for a more gourmet presentation.

Storage and Preservation Guide

Refrigerating Leftovers

Store the soup in an airtight container in the refrigerator for up to 5 days. Note that the wild rice will continue to absorb liquid as it sits, which will make the soup thicker over time. This is normal and can be easily fixed during reheating.

Freezing for Long Term Storage

This soup can be frozen for up to 3 months in freezer-safe containers. To prevent the cream from separating, allow the soup to cool completely before freezing. Leave a small amount of space at the top of the container to allow for expansion during freezing.

Proper Thawing Process

For the best quality, thaw the frozen soup in the refrigerator overnight. This gradual thawing prevents the dairy from breaking. Avoid thawing the soup in the microwave, as this can cause uneven heating and separate the cream.

Effective Reheating Methods

Stovetop Reheating Technique

Gently reheat the soup on the stovetop over medium heat. Stir occasionally to ensure the rice and cream are heated evenly. If the soup has become too thick, stir in a splash of vegetable broth or water to return it to its original consistency.

Microwave Reheating Tips

When using a microwave, heat the soup in 30 to 45 second intervals. Stop and stir between each interval to distribute the heat. This prevents the top layer from becoming too hot while the bottom remains cold.

Managing Dairy Separation

If the cream appears to separate during reheating, whisk the soup vigorously or use an immersion blender for a few seconds. Keeping the heat at medium or low prevents the cream from curdling, which can happen if the soup reaches a rolling boil.

Common Cooking Troubleshooting

What to Do if the Soup is Too Thick

Because wild rice is highly absorbent, the soup can thicken significantly during the simmering or storage phase. Simply stir in 1/4 cup of vegetable broth or water at a time until the desired consistency is reached. Do this slowly to avoid over-thinning the soup.

Fixing Undercooked Rice

If the rice is still too chewy after 60 minutes, continue to simmer for another 10 to 15 minutes. Ensure the lid remains on to trap steam, which is necessary for the grains to soften. Check the rice every 10 minutes to avoid overcooking it into a mush.

Preventing Cheese Clumping

To avoid clumps of Parmesan, stir the cheese in gradually while the soup is off the heat or on very low heat. Stirring continuously ensures the cheese melts smoothly into the liquid. Using finely grated cheese rather than shredded cheese also helps it integrate faster.

Frequently Asked Questions

Can I use a different type of rice?

You can use brown rice, but the texture and flavor will differ. Brown rice is softer and less nutty than wild rice. If using brown rice, reduce the simmering time as it typically cooks faster than wild rice blends.

Is it possible to make this soup in a slow cooker?

Yes, you can sauté the vegetables and mushrooms first, then add them to the crockpot with the rice and broth. Cook on low for 6 to 8 hours or high for 3 to 4 hours. Stir in the cream and cheese just before serving.

What is a good substitute for poultry seasoning?

Herbes de Provence is the best substitute as it contains similar earthy herbs. Alternatively, you can create a mix of 1 tsp dried thyme, 1 tsp dried sage, and 1 tsp dried rosemary to achieve a similar flavor profile.

Can this soup be made without butter?

Yes, you can replace the butter with an equal amount of olive oil or a vegan butter substitute. The butter adds a specific richness, but using only oil will not significantly alter the overall taste of the soup.

How do I prevent the soup from becoming too salty?

Start with low-sodium vegetable broth and omit the salt until the end. Taste the soup after adding the Parmesan cheese, as the cheese provides a significant amount of salt. Add extra kosher salt only if necessary.
