The Coziest Bowl You Will Make This Season
There is something almost magical about a pot of wild rice mushroom soup simmering on the stove. The earthy aroma of golden-sauteed mushrooms, the nutty perfume of wild rice, and the slow bubble of a creamy vegetable broth fill the kitchen in a way that feels genuinely nourishing before you have even taken a single bite. This is the kind of soup that earns a permanent spot in your recipe rotation.
This creamy vegetarian wild rice and mushroom soup is hearty enough to be a full meal, elegant enough to serve to guests, and simple enough to pull off on a weeknight. Whether you are searching for wild rice soup recipes vegetarian style, a deeply satisfying vegan mushroom rice soup, or just a bowl of something warm and wonderful, this recipe delivers every single time.
Why This Recipe Works
The secret to a truly great wild mushroom and rice soup comes down to two things: building flavor in layers and using the right mushrooms.
Instead of dumping everything in at once, we start by searing the mushrooms separately over high heat until they are deeply caramelized. This step alone transforms the soup from good to extraordinary, coaxing out a rich, savory depth that raw or steamed mushrooms simply cannot deliver.
Using a combination of cremini and shiitake mushrooms is another game-changer. Creminis bring that classic earthy meatiness, while shiitakes add a subtle umami punch that makes the broth taste like it has been simmering for hours even when it has not. If you can find them, dried porcini mushrooms reconstituted in warm water are a wonderful addition to this wildrice mushroom soup.
Chef's Tip: A small splash of soy sauce or tamari stirred into the broth deepens the savory flavor dramatically without making the soup taste remotely Asian. It is the quiet secret ingredient in many of the best vegetarian mushroom rice soup recipes.
The Right Tools and Ingredients Matter Here
For a soup this good, a heavy-bottomed Dutch oven makes all the difference. It retains heat evenly, lets you sear the mushrooms properly without scorching, and transitions beautifully from stovetop to a low simmer. Using a quality low-sodium vegetable broth also keeps you in control of the salt level so every bowl tastes perfectly seasoned.
Making It in the Crockpot
This is one of those wild rice soup crockpot vegetarian recipes that adapts beautifully to a slow cooker, which makes it ideal for meal prep or busy days.
The only step you should not skip even for the crockpot version is sauteing the mushrooms and aromatics first. Crockpots trap moisture rather than evaporate it, so raw mushrooms cooked entirely in the slow cooker will turn spongy and pale rather than flavorful and golden. A quick 10-minute saute before loading everything in makes a noticeable difference in the final bowl.
After sauteing, transfer everything to your slow cooker, cook on LOW for 6 to 7 hours, then stir in the cooked wild rice and cream during the last 30 minutes. Simple, hands-off, and deeply satisfying.
Making It Fully Vegan
This recipe is already vegetarian, but turning it into a true vegan mushroom rice soup takes almost no effort at all.
- Swap the butter for olive oil or vegan butter
- Replace the heavy cream with full-fat coconut milk or homemade cashew cream
- Use tamari instead of regular soy sauce if you want it gluten-free as well
The coconut milk version in particular has a subtle sweetness that plays beautifully against the earthy mushrooms and wild rice. Nobody at the table will miss the dairy.

Creamy Vegetarian Wild Rice and Mushroom Soup
This hearty vegetarian wild rice and mushroom soup is rich, creamy, and deeply satisfying, made entirely from wholesome plant-based ingredients and ready in under an hour.
Ingredients
- 1 cup wild rice blend, rinsed
- 16 oz cremini mushrooms, sliced
- 8 oz shiitake mushrooms, stems removed, sliced
- 3 tbsp unsalted butter, or vegan butter for fully vegan version
- 1 yellow onion, finely diced
- 3 celery stalks, thinly sliced
- 2 carrots, peeled and diced
- 4 garlic cloves, minced
- 3/8 cup all-purpose flour, or gluten-free 1:1 flour
- 6 cups vegetable broth, low sodium preferred
- 1 cup heavy cream, or full-fat coconut milk for vegan
- 4 fresh thyme sprigs, or 1 tsp dried thyme
- 2 bay leaves
- 1 tbsp soy sauce, or tamari for gluten-free
- 1 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 blend according to package directions, using vegetable broth instead of water for extra flavor. Set aside when done.
In a large Dutch oven or heavy-bottomed pot, melt the butter over medium-high heat. Add the cremini and shiitake mushrooms in a single layer and cook undisturbed for 3 to 4 minutes until deeply golden. Stir and cook another 2 to 3 minutes. Remove mushrooms and set aside.
Reduce heat to medium. In the same pot, add the diced onion, celery, and carrots. Cook, stirring occasionally, for 6 to 8 minutes until softened and translucent.
Add the minced garlic and cook for 1 minute until fragrant.
Sprinkle the flour over the vegetables and stir continuously for 1 to 2 minutes to cook out the raw flour taste.
Slowly pour in the vegetable broth, about 1 cup at a time, whisking as you go to prevent lumps. Add the soy sauce, thyme sprigs, and bay leaves.
Bring the soup to a gentle boil, then reduce to a simmer. Cook uncovered for 15 minutes, stirring occasionally.
Return the sauteed mushrooms to the pot along with the cooked wild rice. Stir to combine.
Pour in the heavy cream and stir well. Simmer gently for another 8 to 10 minutes until the soup thickens to a creamy, velvety consistency.
Remove and discard the bay leaves and thyme sprigs. Taste and adjust salt and pepper as needed.
Ladle into bowls and garnish with fresh chopped parsley. Serve hot.
Equipment
- Large Dutch oven or heavy-bottomed pot (6 qt or larger)

Notes
Serving and Storing
Serve this mushroom soup wild rice recipe straight from the pot with a thick slice of crusty sourdough or a warm dinner roll on the side. A simple green salad with a lemony vinaigrette is a perfect complement if you want to round out the meal.
Leftovers reheat beautifully and the flavor actually improves overnight as the rice absorbs more of the broth and the spices meld together. Store in an airtight container in the refrigerator for up to 4 days. If you plan to freeze a batch, hold off on adding the cream until you reheat it for the best possible texture.
This is genuinely one of those soups you will find yourself making again and again every time the temperature drops.
