Creamy Vegetarian Wild Rice and Mushroom Soup
This hearty vegetarian wild rice and mushroom soup is rich, creamy, and deeply satisfying, packed with earthy mushrooms, nutty wild rice, and wholesome vegetables in every spoonful.
The Wild Rice Mushroom Soup That Will Become Your Winter Staple
There is something almost magical about a bowl of creamy wild rice mushroom soup. It is the kind of meal that feels like it took all day but comes together in under an hour, the kind that fills your kitchen with an irresistible, earthy aroma and leaves everyone at the table asking for seconds. Whether you are a lifelong vegetarian or simply trying to eat a little less meat this season, this vegetarian wild rice soup is the recipe that will earn a permanent spot in your rotation.
This is not a thin, watery broth situation. We are talking about a deeply savory, velvety soup built on a foundation of golden-sauteed cremini and shiitake mushrooms, sweet carrots and celery, and that wonderfully nutty chew of wild rice. A simple butter-and-flour roux gives it body, and a final pour of cream transforms the whole pot into something that feels genuinely luxurious. And yet, every ingredient is humble and wholesome.
Why Wild Rice Makes All the Difference
If you have ever made a rice soup with standard long-grain white rice and wondered why it felt a little flat, wild rice is your answer. Technically a semi-aquatic grass rather than a true rice, wild rice brings a firm, slightly chewy texture that holds up beautifully through long simmering without turning to mush. Its flavor is nutty and almost smoky, which pairs perfectly with the deep, umami-forward character of mushrooms.
For this soup, a wild rice blend (usually a mix of wild rice, brown rice, and red rice) works wonderfully and cooks a bit more evenly than pure wild rice alone. Look for blends in the bulk bins or grain aisle of most grocery stores.
Chef's Tip: Always cook your wild rice separately and stir it into the finished soup. This gives you total control over texture and prevents the rice from absorbing all your beautiful broth if the soup sits overnight.
The Mushroom Strategy
The soul of this wild mushroom and rice soup is, of course, the mushrooms. Using two types is the move here. Cremini mushrooms bring a reliable, meaty bulk to the pot. Shiitake mushrooms add a distinctly woodsy, almost smoky depth that regular button mushrooms simply cannot replicate.
The single most important mushroom tip: do not crowd the pan. Let them sit undisturbed in a hot pan with butter and olive oil until they develop a deep golden-brown crust. That caramelization is pure flavor. Rushing this step by stirring too early steams the mushrooms instead of searing them, and you will lose the rich, savory base that makes this soup so memorable.
Having a good heavy-bottomed Dutch oven makes a real difference when building this kind of deeply layered soup. It retains heat evenly, prevents scorching, and gives mushrooms the consistent high heat they need to brown properly.
Building Layers of Flavor
The secret depth in this vegan mushroom rice soup (easily made vegan with a few swaps) comes from a small but mighty tablespoon of soy sauce stirred in with the broth. It adds a savory, umami backbone that makes tasters say "what is that flavor?" without ever identifying it as soy sauce. It is a professional chef trick that works beautifully in vegetarian soups where you are missing the natural richness of meat-based stock.
Fresh thyme and a pinch of dried rosemary round out the herb profile without overpowering the earthy mushroom and wild rice notes. Two bay leaves simmered low and slow tie everything together.
Make It Vegan: Swap the butter for good-quality vegan butter and replace the heavy cream with full-fat coconut milk for a rich, dairy-free version. The flavor is slightly different but every bit as satisfying.

Creamy Vegetarian Wild Rice and Mushroom Soup
This hearty vegetarian wild rice and mushroom soup is rich, creamy, and deeply satisfying, packed with earthy mushrooms, nutty wild rice, and wholesome vegetables in every spoonful.
Ingredients
- 1 cup wild rice blend, rinsed well
- 16 oz cremini mushrooms, sliced
- 8 oz shiitake mushrooms, stems removed, caps sliced
- 3 tbsp unsalted butter, or vegan butter for a fully vegan version
- 2 tbsp olive oil, extra virgin
- 1 yellow onion, finely diced
- 3 celery stalks, thinly sliced
- 3 carrots, peeled and diced
- 4 garlic cloves, minced
- 3/8 cup all-purpose flour, use gluten-free 1:1 flour if needed
- 6 cups vegetable broth, low sodium preferred
- 1 tbsp fresh thyme, leaves only, or 1 tsp dried
- 1/2 tsp dried rosemary
- 2 bay leaves, removed before serving
- 1 cup heavy cream, or full-fat coconut milk for a vegan version
- 1 tbsp soy sauce, adds umami depth
- 1 1/2 tsp kosher salt, plus more to taste
- 1/2 tsp black pepper, freshly ground
- 1/4 cup fresh parsley, chopped, for garnish
Instruction
Cook the wild rice: In a medium saucepan, combine the rinsed wild rice blend with 2.5 cups of water and a pinch of salt. Bring to a boil, then reduce heat to low, cover, and simmer for 40 to 45 minutes until tender and most liquid is absorbed. Drain any excess liquid and set aside.
Saute the aromatics: In a large Dutch oven or heavy-bottomed pot, melt the butter with the olive oil over medium-high heat. Add the onion, celery, and carrots with a pinch of salt. Cook, stirring occasionally, for 6 to 8 minutes until the vegetables are softened and the onion is translucent.
Cook the mushrooms: Add all the mushrooms to the pot. Cook undisturbed for 3 minutes, then stir and continue cooking for another 4 to 5 minutes until they are golden brown and have released most of their moisture. Add the garlic, thyme, and rosemary and cook for 1 minute more until fragrant.
Build the roux: Sprinkle the flour over the vegetables and mushrooms. Stir continuously for 2 minutes to cook out the raw flour taste and coat everything evenly.
Add the broth: Pour in the vegetable broth gradually, stirring constantly to prevent lumps. Add the soy sauce and bay leaves. Bring the soup to a gentle boil, then reduce heat to medium-low and simmer uncovered for 15 minutes, allowing the flavors to meld and the soup to thicken slightly.
Finish the soup: Remove and discard the bay leaves. Stir in the cooked wild rice and the heavy cream (or coconut milk). Simmer gently for 5 more minutes. Taste and adjust salt and pepper as needed.
Serve: Ladle into bowls and garnish generously with freshly chopped parsley. Serve with crusty bread on the side.

Notes
Serving, Storing, and Making It Your Own
This vegetarian mushroom rice soup is a full meal on its own, but a thick slice of crusty sourdough or a warm, buttery dinner roll alongside it is never a bad idea. A simple green salad with a bright lemon vinaigrette cuts through the richness beautifully if you want to round out the meal.
Leftovers taste even better the next day as the flavors continue to develop overnight. Store in an airtight container in the refrigerator for up to 4 days, or freeze the soup before adding the cream and stir in fresh cream after reheating.
A few easy variations to try:
- Add a handful of baby spinach or kale in the last 5 minutes for extra greens.
- Stir in a can of white beans for an even heartier, protein-packed bowl.
- Top with crispy fried shallots for a little crunch and sweetness.
- A drizzle of good truffle oil right before serving elevates this into dinner-party territory.
Whether you are searching for wild rice soup recipes vegetarian for a weeknight dinner or a make-ahead lunch for the week, this recipe has you covered. It is wholesome, deeply satisfying, and proof that meatless cooking can be every bit as rich and comforting as anything else on the table.
