Uncle Ben’s Wild Rice Soup Recipe: Creamy Mushroom and Herb Infusion

This wild rice soup proves that vegetarian dishes can be just as rich and satisfying as their meat-based counterparts.

I developed this version after testing multiple recipes in my tiny Boston kitchen, focusing on achieving that creamy texture without dairy overload. The wild rice adds a nutty depth that pairs perfectly with earthy mushrooms and fresh herbs.

The secret lies in slow-simmering the vegetables to build maximum flavor before adding the rice and broth. A final splash of cream creates the luxurious consistency that makes this soup irresistibly comforting.

It’s the kind of dish that warms you from the inside out, with every spoonful delivering layers of umami and herbaceous notes.

Ingredients for Uncle Ben’s Wild Rice Soup

Rich, earthy flavors come together in this comforting vegetarian bowl with wild rice and mushrooms.

The wild rice is the soul of this soup. Uncle Ben’s is my go-to—find it in the rice aisle at any major supermarket. The mushrooms need to be fresh and firm (no slimy ones in the back of the fridge). I grab cremini from Whole Foods or Trader Joe’s—they’ve got the best selection. For the broth, Imagine or Pacific Foods brands are solid choices if you’re not making your own.

No cremini? Baby bella or white button work just as well. Short on fresh herbs? Dried thyme at one-third the amount gets you close (skip the rosemary—it’s too potent dried). If you’re avoiding dairy, swap the cream for coconut milk (full-fat, not the light kind). The butter can be vegan butter too, but I find the real stuff gives the best flavor here.

This keeps beautifully—honestly tastes better the next day. Store in the fridge for up to 4 days, or freeze for 3 months. Reheat gently on the stove (microwave makes the rice weirdly chewy). Always make a double batch—it’s that good.

Step-by-Step Instructions for Creamy Wild Rice Soup

This method ensures a rich, velvety texture with perfectly cooked rice and deeply flavored broth.

Step 1: Cook the Wild Rice Blend

Rinse the 1 cup Wild Rice Blend under cold water to remove any excess starch. In a medium pot, combine the rice with 2 cups of the 6 cups Vegetable Broth and bring to a boil. Reduce heat to low, cover, and simmer for 45-50 minutes until the rice is tender and the liquid is absorbed.

The grains should be plump and split slightly when done. If the rice isn’t soft but the liquid is gone, add another ½ cup of the broth and continue cooking. Drain any excess liquid before proceeding.

Step 2: Sauté the Aromatic Vegetables

In a large pot or Dutch oven, melt the ½ cup Unsalted Butter over medium heat. Add the 1 lb Cremini Mushrooms, 1 whole Yellow Onion, 2 whole Carrots, and 2 whole Celery Stalks. Sauté for 8-10 minutes until the vegetables soften and the mushrooms release their moisture.

Stir in the 4 cloves Garlic Cloves and cook for another 1-2 minutes until fragrant. The mixture should be golden and the onions translucent—this builds the flavor base for your soup.

Step 3: Create the Creamy Roux and Broth Base

Sprinkle the ¼ cup All-Purpose Flour over the sautéed vegetables and stir to coat evenly. Cook for 2 minutes to remove the raw flour taste. Gradually whisk in the remaining 4 cups Vegetable Broth until smooth.

Add the 4 whole Fresh Thyme Sprigs, 1 whole Fresh Rosemary Sprig, 1 whole Bay Leaf, 1½ tsp Salt, and ½ tsp Black Pepper. Stir well and bring to a gentle simmer.

Step 4: Combine and Finish with Heavy Cream

Add the cooked Wild Rice Blend to the pot and stir to combine. Let the soup simmer for 10 minutes to allow the flavors to meld. The rice should be tender and the broth slightly thickened.

Stir in the 1 cup Heavy Cream and simmer for another 5 minutes until the soup reaches your desired creaminess. Taste and adjust seasoning if needed—the cream should mellow the flavors beautifully.

Remove the thyme sprigs, rosemary sprig, and bay leaf before serving. The soup should be velvety, with a rich, herb-infused aroma and a perfect balance of earthy mushrooms and tender rice.

Pro Cooking Tips for uncle bens wild rice soup

Rice Cooking Precision

Rinsing the Wild Rice Blend is crucial—it removes excess starch that could make your soup gummy. I always use a fine-mesh strainer for this. Cook the rice separately first to ensure perfect texture before adding to the soup base. 🌾

Vegetable Sautéing Depth

Don’t rush the 8-10 minute sauté for mushrooms and aromatics. The mushrooms should release all their moisture, then reabsorb it, creating that deep umami base. I use my Le Creuset Dutch oven for even heat distribution.

Roux Technique

When adding the ¼ cup flour, cook it for the full 2 minutes to eliminate any raw taste. Whisk constantly as you pour in the broth to prevent lumps. The mixture should turn a light golden color before adding liquids.

Herb Management

Tie the thyme and rosemary in cheesecloth for easy removal later, or fish out the sprigs carefully before serving. The bay leaf is easier to spot and remove. I learned this trick after too many bites of accidental rosemary stems.

Cream Incorporation

Temper the 1 cup Heavy Cream by stirring in a ladle of hot soup first, then add it to the pot. This prevents curdling. Simmer gently after adding—never boil, or the cream may separate. 💡

Final Texture Check

If the soup is too thick, thin with additional broth. Too thin? Simmer uncovered for 5-10 minutes. The rice will continue absorbing liquid, so check consistency again before serving.
