How to Make Creamy Mushroom Vegetable Rice Soup

1. Sauté the Vegetables

Heat the olive oil in a large Dutch oven or soup pot over medium-high heat.

Once the oil is hot, add the chopped sweet onion, diced carrots, and celery.

Cook for about 2 minutes, stirring occasionally, until the onion begins to turn lightly golden.

Add the minced garlic and Italian herb seasoning. Cook for another minute, stirring frequently so the garlic doesn’t burn.

2. Cook the Mushrooms

Add the sliced mushrooms to the pot.

Cook for approximately 5 minutes, stirring occasionally, until the mushrooms become tender and most of the liquid they release has evaporated.

Season with 1 teaspoon of sea salt.

Tip: Letting the mushroom liquid cook off helps concentrate their earthy flavor and prevents the finished soup from tasting watery.

3. Add the Rice and Broth

Stir the white rice into the mushroom and vegetable mixture.

Pour in the vegetable broth and scrape the bottom of the pot with a wooden spoon or spatula to loosen any flavorful browned bits.

Cover the pot and bring the soup to a gentle simmer.

Once simmering, reduce the heat to maintain a steady simmer and cook for about 15 minutes, or until the rice is tender.

Tip: Stir occasionally and make sure the rice isn’t sticking to the bottom of the pot.

4. Make the Creamy Bean Puree

While the rice is cooking, add the drained and rinsed white beans and 1 cup of water to a blender.

Blend until completely smooth and creamy.

This simple bean puree is what gives the soup its luxurious texture without using cream, milk, or butter.

Tip: If your blender has a tendency to trap ingredients around the bottom, stop and scrape down the sides as needed to ensure the beans become completely smooth.

5. Add the Creamy Base

Once the rice is fully cooked, remove the lid.

Stir the smooth white bean puree into the soup until it is evenly incorporated.

The broth will immediately become thicker and creamier.

6. Add the Spinach

Stir in the roughly chopped baby spinach.

Cook for a minute or two, just until the spinach wilts into the hot soup.

Avoid overcooking the spinach so it retains its fresh color and flavor.

7. Finish with Lemon and Seasoning

Add 1–2 tablespoons of fresh lemon juice.

Taste the soup and adjust the salt and black pepper as needed.

If the soup is thicker than you prefer, stir in additional water until it reaches your desired consistency.

Serve warm and enjoy!

Tips for Success

• Brown the vegetables slightly: Allowing the onion to develop some golden color adds extra depth to the soup.
• Cook the mushrooms thoroughly: Let most of their released liquid evaporate for a richer mushroom flavor.
• Use low-sodium broth: This gives you better control over the final salt level.
• Blend the beans until smooth: A completely smooth bean puree creates the creamiest texture.
• Watch the rice: Rice continues absorbing liquid even after cooking, so the soup will naturally thicken as it sits.
• Adjust with water: Add extra water before serving or when reheating if the soup becomes too thick.
• Re-season after adding water: Additional liquid can dilute the seasoning, so always taste before serving.
• Add lemon at the end: Fresh lemon juice brightens the entire soup and keeps the flavors from feeling too heavy.

Equipment Needed

• Large Dutch oven or soup pot
• Blender
• Wooden spoon or spatula
• Chef’s knife
• Cutting board
• Measuring cups and spoons

If you don’t have a Dutch oven, any large heavy-bottomed soup pot will work.

Recipe Variations

Creamy Mushroom Wild Rice Soup

Replace the white rice with wild rice for a heartier texture and deeper, nuttier flavor. Keep in mind that wild rice may require a longer cooking time.

Extra Mushroom Soup

For an even more mushroom-forward version, use a mixture of cremini, button, shiitake, or oyster mushrooms.

Creamy Mushroom Potato Soup

Replace some or all of the rice with diced potatoes. The potatoes will make the soup extra hearty and comforting.

White Bean and Kale Soup

Swap the baby spinach for chopped kale. Kale is sturdier than spinach, so give it a few extra minutes to become tender.

Herby Lemon Mushroom Soup

Add fresh thyme, rosemary, or parsley along with the Italian seasoning for an even more aromatic soup.

Serving Suggestions

This creamy mushroom vegetable rice soup is satisfying enough to serve as a main course, especially with a few simple sides.

Serve it with:

• Crusty artisan bread
• Garlic bread
• Toasted sourdough
• Vegan dinner rolls
• Simple green salad
• Roasted vegetables
• Crackers
• Fresh herbs

For an attractive presentation, ladle the soup into warm bowls and finish with freshly cracked black pepper, chopped parsley, and a small squeeze of lemon.

A drizzle of olive oil over the top can also add a beautiful finishing touch.

How to Store Creamy Mushroom Vegetable Rice Soup

Allow the soup to cool completely before transferring it to an airtight container.

Store it in the refrigerator for up to 3 days.

Keep in mind that the rice will continue absorbing the broth as the soup sits, so leftovers will become considerably thicker.

When reheating, stir in additional water or vegetable broth until the desired consistency is restored. Taste and adjust the seasoning again after adding liquid.

Can You Freeze This Soup?

This soup can be frozen, although the texture of the rice may change slightly after freezing and reheating.

For best results, cool the soup completely before transferring it to freezer-safe containers.

Leave a little room at the top of each container for expansion.

Thaw overnight in the refrigerator and reheat gently on the stovetop. Add extra water or vegetable broth as needed to loosen the soup.

FAQs

Is this mushroom rice soup vegan?

Yes. This recipe is completely vegan because the creamy texture comes from blended white beans rather than dairy cream, milk, or butter.

Is Creamy Mushroom Vegetable Rice Soup gluten-free?

Yes, the ingredients listed are naturally gluten-free. Always check the labels on your vegetable broth and seasonings if you need to avoid gluten strictly.

How does this soup become creamy without cream?

The secret is blended white beans. The beans are pureed with water until smooth and then stirred into the soup, creating a naturally creamy texture while adding protein and fiber.

Why does my soup become so thick after sitting?

The rice continues absorbing liquid as the soup cools and sits in the refrigerator. Simply add water or vegetable broth when reheating until the soup reaches your preferred consistency.

Can I use brown rice instead of white rice?

Yes, although brown rice generally takes longer to cook and may require additional broth or water. Adjust the cooking time according to the type of rice you use.

Can I use frozen spinach?

Absolutely. Frozen spinach is a convenient substitute for fresh baby spinach. Add it toward the end of cooking and heat until completely warmed through.
