This creamy wild rice soup is the ultimate cold-weather comfort food, featuring a velvety, rich broth packed with earthy mushrooms, tender vegetables, and nutty wild rice. The combination of a proper mirepoix and a simple roux creates deep, savory flavor that makes this soup genuinely luxurious while using everyday pantry ingredients.
Equipment
- Large Dutch oven or heavy-bottomed soup pot - at least 5-6 quart capacity
- Wooden spoon or heat-resistant silicone spatula
- Chef's knife
- Cutting board
- Measuring cups and spoons
- Ladle
- Fine-mesh strainer - optional, for rinsing rice
- Immersion Blender - optional, for a smoother broth
Ingredients
- 1 cup raw wild rice - 185g, or wild rice blend
- 3 tablespoons unsalted butter - 45g
- 1 medium yellow onion - finely diced
- 3 medium celery stalks - finely diced
- 2 medium carrots - peeled and finely diced
- 4 cloves garlic - minced
- 8 oz cremini or white button mushrooms - 225g, thinly sliced
- 1/3 cup all-purpose flour - 40g
- 6 cups vegetable or chicken broth - 1.4 liters, low-sodium recommended
- 1 cup heavy cream - 240ml
- 1 teaspoon dried thyme
- 1/2 teaspoon dried rosemary
- 1/2 teaspoon garlic powder
- salt and black pepper - to taste
For Garnish
- fresh thyme or parsley - optional, for garnish
Instructions
- Rinse the wild rice in a fine mesh strainer under cold water for 30-60 seconds, then set aside to drain.
- Finely dice the onion, celery, and carrots to uniform 1/4-inch pieces. Mince the garlic and slice the mushrooms thinly.
- In a large Dutch oven over medium heat, melt the butter. Add the onion, celery, and carrots and cook for 7-9 minutes until softened and fragrant.
- Push vegetables to the sides, add garlic to the center, and cook for 30-60 seconds until fragrant. Add mushrooms and cook for 4-5 minutes until their moisture has evaporated.
- Sprinkle dried thyme, rosemary, garlic powder, and pepper over the vegetables and cook for 30-60 seconds to bloom the herbs.
- Add the flour and stir constantly for 1-2 minutes until the raw flour smell disappears and the mixture smells nutty.
- Gradually pour in the broth while whisking continuously to prevent lumps. Add the rinsed wild rice and stir to combine.
- Bring to a gentle boil, then reduce heat to medium-low, cover with the lid slightly ajar, and simmer for 40-50 minutes until the rice is tender and the grains have split open.
- Reduce heat to low and stir in the heavy cream. Warm through for 3-5 minutes without letting the soup boil.
- Taste and adjust seasoning with salt and pepper. Optionally blend 1-2 cups of soup with an immersion blender for a creamier texture. Serve hot, garnished with fresh thyme or parsley.
Notes
- Don't rush the mirepoix — cooking the onion, celery, and carrots slowly creates the sweet, savory base essential for deep flavor.
- Cook the roux for at least 1-2 minutes to eliminate the raw flour taste; this is non-negotiable for a good-tasting cream soup.
- Whisk the broth in gradually to prevent lumps and ensure a silky smooth texture from the start.
- Never boil the soup after adding the cream — high heat can cause the cream to separate or curdle. Keep it on low heat.
- Season at the end because broth reduces and concentrates in flavor as the rice cooks, so always taste before adjusting salt.
- Use room temperature cream to reduce the chance of curdling when adding it to hot soup.
- Cook the mushrooms until their moisture has evaporated and they begin to brown — this develops their savory, umami flavor rather than just steaming them.
- Store cooled soup in an airtight container in the refrigerator for up to 4 days. The soup will thicken as it sits — add a splash of broth when reheating.
- Freeze for up to 3 months, but for best results, freeze before adding the cream and stir it in fresh when reheating.
- To make this gluten-free, replace the flour with a 1:1 gluten-free flour blend or use a cornstarch slurry (2 tablespoons cornstarch mixed with 3 tablespoons cold water) stirred in during the last 10 minutes of cooking.
