Cream of Mushroom and Wild Rice Soup Recipe: Earthy Depth With Every Spoon

There’s a reason this soup becomes a winter staple in my kitchen—it delivers earthy depth without complicated techniques. The wild rice adds a nutty chew that perfectly complements the creamy mushroom base.

I’ve refined this recipe over years to balance richness with brightness. The key is sautéing the mushrooms until deeply browned before adding liquid, which builds layers of umami that carry through the entire pot.

What emerges is a velvety soup with tender wild rice suspended in a broth so flavorful you’ll want to soak it up with crusty bread. It’s hearty enough for a meal but elegant enough for company.

One pot, 45 minutes, and a bowl of comfort that tastes like it simmered all day.

Ingredients for Cream of Mushroom and Wild Rice Soup

Rich mushrooms, nutty wild rice, and a handful of aromatics create this velvety soup.

The mushrooms are the soul of this dish. Creminis and shiitakes give that deep, earthy flavor—skip the white button if you can. Whole Foods or Trader Joe’s usually have fresh shiitakes. Wild rice blends (like from Lundberg) cook faster than pure wild rice but still deliver that nutty chew. For the wine, any dry white you’d drink works (I keep a cheap Sauvignon Blanc on hand just for cooking).

No white wine? Extra vegetable stock with a squeeze of lemon brightens it up. Out of fresh thyme? Dried at one-third the amount works, but fresh really shines here. If you’re avoiding dairy, swap the butter for olive oil and the cream for full-fat coconut milk—the flavor changes, but it’s still delicious. Pre-sliced mushrooms save time, but whole ones brown better.

This soup thickens as it sits—add a splash of stock when reheating. Keeps 4-5 days in the fridge, freezes beautifully for 3 months. I like to make a double batch and stash half in the freezer for lazy nights (it’s even better the second time around).

Step-by-Step Instructions for Cream of Mushroom and Wild Rice Soup

Here’s the method. Straightforward, tested, works every time.

Step 1: Cook the Wild Rice Blend to Perfection

Rinse the 1 cup Wild Rice Blend under cold water until the water runs clear. This removes excess starch and prevents the grains from becoming gummy. In a medium saucepan, combine the rinsed rice with 2 cups of the vegetable stock.

Bring to a boil over high heat, then reduce to a simmer, cover, and cook for 45-50 minutes until the grains are tender and have absorbed most of the liquid. The rice should be chewy but not hard in the center. Drain any remaining liquid and set the cooked rice aside.

Step 2: Sauté the Mushrooms and Aromatics

In a large pot or Dutch oven, melt 0.25 cup unsalted butter over medium-high heat. Add the 16 oz Cremini Mushrooms and 8 oz Shiitake Mushrooms, cooking for 8-10 minutes until they release their moisture and turn a deep golden brown.

Add the finely diced yellow onion and cook for another 3-4 minutes until translucent. Stir in the 4 cloves minced garlic cloves and cook for 30 seconds until fragrant. Season with 1.5 tsp kosher salt and 1 tsp freshly ground black pepper to enhance the natural umami of the mushrooms.

Step 3: Build the Roux and Deglaze

Sprinkle the 0.25 cup all-purpose flour over the mushroom mixture and stir to coat. Cook for 1-2 minutes to remove the raw flour taste. This creates a roux that will thicken the soup beautifully.

Pour in the 0.5 cup dry white wine and scrape up any browned bits from the bottom of the pot. Let the wine simmer for 2 minutes to cook off the alcohol. Add the remaining 4 cups vegetable stock, the 4 whole fresh thyme sprigs, and the 1 whole bay leaf. Bring to a boil, then reduce heat to maintain a gentle simmer.

Step 4: Combine and Finish the Soup

Stir the cooked wild rice blend into the pot. Simmer for 10 minutes to allow the flavors to meld together. The soup should thicken slightly, coating the back of a spoon.

Remove from heat and stir in the 1 cup heavy cream. Discard the thyme sprigs and bay leaf before serving. Taste and adjust the seasoning if needed. The soup should have a velvety texture and a rich, earthy depth from the mushrooms and wild rice.

Step 5: Garnish and Serve

Ladle the soup into bowls and garnish with the 0.25 cup chopped fresh parsley. The parsley adds a pop of color and a fresh contrast to the rich, creamy soup.

Serve immediately while hot. The soup will continue to thicken as it cools, so if it’s too thick, thin it with a splash of additional vegetable stock. This dish is hearty enough to stand alone but pairs beautifully with a crisp green salad.

Essential Equipment for Great cream of mushroom and wild rice soup

Dutch Oven Essentials

A heavy 5-6 quart Dutch oven is my go-to for this soup. The even heat distribution prevents hot spots that can scorch the roux or mushrooms. I use my Le Creuset—it’s pricey but lasts forever. A budget-friendly Lodge enameled cast iron works just as well for 1/3 the cost. 💪

Wooden Spoon for Stirring

A wooden spoon won’t scratch your pot’s surface while stirring the roux or scraping up browned bits. The flat edge helps deglaze efficiently. Avoid metal utensils with enameled cast iron to preserve the finish.

Sharp Chef’s Knife

You’ll need a 8-inch chef’s knife to slice 24 oz of mushrooms and dice the onion uniformly. I swear by Wüsthof or Victorinox Fibrox—both stay sharp and feel balanced. A dull knife makes prep slower and more dangerous.

Fine Mesh Strainer

Rinsing the wild rice blend removes excess starch, and a fine mesh strainer catches all the tiny grains. I keep a Cuisinox one in my cabinet—it’s sturdy and doesn’t rust. Skip this step, and your soup might turn gummy.

Instant-Read Thermometer

While not strictly necessary, a digital instant-read thermometer ensures your soup stays at a safe serving temperature of 165°F. I use a ThermoWorks ThermaPen for accuracy. It’s also handy for checking the rice’s doneness. 🌡️

Immersion Blender

For a smoother texture, I blend half the soup with an immersion blender before adding the cream. A Cuisinart SmartStick is powerful and easy to clean. This step is optional but adds a luxurious mouthfeel.
