Wild Rice Mushroom Soup

Featured in: Weeknight Dinners

This hearty soup combines nutty wild rice with earthy mixed mushrooms like cremini, shiitake, and oyster varieties. Sautéed onions, celery, and carrots create a flavorful base, while fresh thyme, rosemary, and parsley add aromatic depth. A touch of cream creates luxurious richness, and a splash of soy sauce enhances the savory umami notes.

The preparation involves building a vegetable base, adding mushrooms until they release their liquids, then thickening with flour before simmering with broth and wild rice. The result is a satisfying bowl that's naturally vegetarian and can be made gluten-free or vegan with simple substitutions.

Perfect for meal prep, this soup develops even deeper flavors when made ahead. Serve with crusty bread for a complete, nourishing meal that warms you from the inside out.

The first time the air turned crisp enough to see my breath I knew it was soup season. My tiny apartment kitchen used to fill with the steam from a bubbling pot of wild rice and earthy mushrooms. It was the kind of meal that made the drafty windows feel like a charming feature rather than a nuisance. I learned quickly that the slow dance of the rice grains popping open was the best timer for a relaxing evening.

One rainy Tuesday I accidentally let the mushrooms brown a bit too much fearing I had ruined the batch. Instead those slightly charred edges infused the broth with a smoky depth that I have tried to replicate every time since. The kitchen smelled like damp earth and toasted nuts which is a combination that still brings me a sense of peace.

Ingredients

  • Mixed Wild Mushrooms: Using a variety like shiitake and cremini adds layers of texture and a richer umami profile.
  • Wild Rice: Ensure you buy actual wild rice rather than a blend to keep that distinct nutty snap.
  • Heavy Cream: This brings everything together into a velvety embrace but can be swapped for cashew cream.
  • Fresh Thyme and Rosemary: These woody herbs are the backbone of the aromatics and smell like a mountain cabin.
  • Soy Sauce: My secret weapon for deepening the color and adding a salty punch that salt alone cannot provide.
  • Vegetable Broth: This provides the savory liquid base that allows the rice to simmer into tenderness.
  • All Purpose Flour: A small amount of flour helps thicken the soup just enough to feel hearty.
  • Mirepoix Base: The combination of onion celery and carrots creates a sweet and savory foundation.

Soften the base:
Heat the olive oil in your pot and sauté the onion celery and carrots until they are soft and fragrant. This step creates the sweet aromatic foundation for the entire dish.
Infuse the aromatics:
Stir in the garlic thyme rosemary and the bay leaf for about a minute. You want the herbs to wake up and fill the room with their scent.
Sear the mushrooms:
Toss in your sliced mushrooms and cook them until their liquid evaporates and they turn a beautiful golden brown. Patience here ensures the mushrooms have a meaty texture rather than a rubbery one.
Build the thickness:
Sprinkle the flour over the vegetables and stir constantly for two minutes to cook off the raw taste. Gradually pour in the broth while whisking to keep the texture perfectly smooth.
Simmer the rice:
Add the rinsed wild rice and soy sauce then bring the pot to a boil before lowering the heat. Cover it and let it simmer for about forty five minutes until the rice grains curl open.
The creamy finish:
Remove the bay leaf and stir in the heavy cream and fresh parsley. Let it bubble gently for a few more minutes then season with plenty of black pepper and salt.

My brother once visited and claimed he hated mushrooms until he tried a bowl of this creamy concoction. He ended up asking for seconds and even took a container home for his lunch the next day. It is the kind of dish that converts skeptics with its hearty and savory charm.

Choosing The Best Fungi

I find that wiping the mushrooms with a damp cloth instead of washing them under the tap keeps them from getting soggy. It is a small step that makes a huge difference in how they brown in the pot.

The Art Of Wild Rice

Wild rice is notoriously stubborn and will not be rushed by high heat so keep the flame low. I usually use this simmering time to tidy up the kitchen or finally finish that chapter in my book.

Serving And Storage

A thick slice of toasted sourdough is the perfect vessel for soaking up every last drop of the creamy broth. I like to add a tiny extra crack of black pepper right before the bowl hits the table.

  • Keep an extra splash of broth handy if you plan on reheating this the next day.
  • Fresh parsley adds a necessary pop of color to the deep browns of the soup.
  • Try a tiny squeeze of lemon if you want to brighten up the earthy flavors.

Cooking Q&A

What type of mushrooms work best?

Mixed wild mushrooms like cremini, shiitake, and oyster create the best flavor profile. Button mushrooms can be used, but the earthy varieties provide more depth and richness to the finished soup.

Can I make this ahead of time?

Absolutely. This soup actually tastes better the next day as flavors meld together. Store in the refrigerator for up to 4 days and reheat gently, adding extra broth if needed to adjust consistency.

Is wild rice the same as regular rice?

Wild rice is actually a semi-aquatic grass, not true rice. It has a nutty flavor, chewy texture, and requires longer cooking time than white or brown rice. It holds its shape well in soups and adds wonderful texture.

How can I make this vegan?

Replace the heavy cream with cashew cream, coconut cream, or your favorite plant-based cream alternative. Use gluten-free flour if needed, and ensure your soy sauce is gluten-free. The result remains just as creamy and satisfying.

Why add soy sauce to soup?

Soy sauce adds umami—savory depth that enhances the mushroom flavor without making the taste Asian-inspired. It's a chef's secret for boosting richness in vegetarian soups and stews.

Can I freeze this soup?

Freeze before adding the cream for best results. The rice and mushrooms freeze well, but cream can sometimes separate when thawed. Add fresh cream when reheating for the smoothest texture.
