It is hearty enough to be a full meal, elegant enough for company, and simple enough for a Tuesday night.
Before we dive in, a word about ingredients and tools. The quality of your mushrooms and broth will make a real difference in the depth of flavor here, and a good heavy-bottomed Dutch oven ensures even heat distribution without scorching.
The secret to a truly great vegetarian mushroom rice soup lies in layering flavor at every step. Rather than dumping everything in a pot at once, we take a few extra minutes to:
Chef's Tip: Use a mix of cremini and shiitake mushrooms for the best results. Creminis bring body and earthiness, while shiitakes add a slightly smoky, meaty depth that makes this mushroom soup wild rice recipe genuinely crave-worthy.
This recipe works beautifully on the stovetop in about an hour, but it is also one of the best wild rice soup crockpot vegetarian adaptations you will find. For the slow cooker version, saute the aromatics and mushrooms on the stovetop first (do not skip this step), then transfer everything to your crockpot with the broth and uncooked rice. Cook on low for 6 to 7 hours, then stir in cream at the end.
For a fully vegan mushroom rice soup, swap the butter for good olive oil and use full-fat coconut milk or oat cream in place of heavy cream. The result is just as luscious.
This soup is a complete meal on its own, but a few simple sides take it over the top:

This cozy Creamy Vegetarian Wild Rice and Mushroom Soup is rich, hearty, and packed with earthy flavor. Perfect for a weeknight dinner or slow cooker meal the whole family will love.
Cook the wild rice: In a medium saucepan, combine the rinsed wild rice blend with 2 cups of water. Bring to a boil, then reduce heat to low, cover, and simmer for 40 to 45 minutes until the rice is tender and the liquid is absorbed. Set aside.
Saute the aromatics: In a large Dutch oven or heavy-bottomed pot, melt the butter over medium heat. Add the diced onion, celery, and carrots. Cook, stirring occasionally, for 6 to 8 minutes until softened and the onion is translucent.
Add the mushrooms: Stir in the cremini and shiitake mushrooms. Cook for 8 to 10 minutes, stirring occasionally, until the mushrooms have released their liquid and are golden brown. Add the garlic, thyme, and rosemary and cook for another 1 minute until fragrant.
Build the base: Sprinkle the flour over the vegetable and mushroom mixture. Stir well to coat everything evenly and cook for 2 minutes to eliminate the raw flour taste.
Add the broth: Slowly pour in the vegetable broth, stirring constantly to prevent lumps. Add the soy sauce and bring the soup to a gentle boil. Reduce heat and simmer for 10 minutes.
Add the rice and cream: Stir in the cooked wild rice and the heavy cream (or coconut milk). Simmer for another 5 minutes until the soup is creamy and slightly thickened.
Season and serve: Taste and adjust salt and pepper as needed. Ladle into bowls and garnish with fresh parsley. Serve with crusty bread.
Leftovers keep well in the fridge for up to 4 days in an airtight container. The soup will thicken as it sits because the wild rice continues to absorb liquid, so add a splash of broth when reheating to bring it back to the right consistency.
This soup also freezes beautifully for up to 2 months. For best results, freeze it before adding the cream, then stir the cream in fresh when you reheat it. Your future self will thank you.
