Wild Rice Soup Ingredients

You’ll need to get the following ingredients to make this soup:

  • Carrots
  • Celery stalks
  • Onion - we use white or yellow onions for this
  • Garlic cloves
  • Uncooked wild rice
  • Fresh mushrooms
  • Vegetable broth - the color of the soup may vary depending on the color of the broth
  • Salt
  • Italian Herb Mix 
  • Spinach

For the roux, you’ll need the following ingredients:

  • Butter - for a vegan option, use olive oil or canola oil
  • Milk - for a vegan option, use an unsweetened, unflavored milk alternative such as soy milk
  • Flour - to make this gluten free, substitute half as much flour with cornstarch

How to make Instant Pot Wild Rice Soup

Wild rice soup is easy to make in the Instant Pot. 

wild rice soup instructions

Start by making the soup base. To do this, mix all the soup ingredients - veggies, rice, broth, and seasonings - in the Instant Pot’s inner pot. Close the lid on the Instant Pot and set the valve to sealing. Set the pot to cook on high heat for 45 minutes. When the timer goes off, do a quick release of pressure.

During the last 5 minutes of cooking, it is time to make the roux. Use a small pot to melt the butter over medium-low heat. When the butter is melted, add the flour and mix to combine. Slowly whisk in the milk and continuously whisk for about 1 minute until the sauce is thick and creamy.

Carefully remove the lid to the Instant Pot. Mix in the greens and the roux.

Once the soup has thickened some, garnish it with some red pepper flakes or cheese. Serve the soup with a crusty loaf of artisan bread on the side.

How to make Wild Rice Soup on the Stove Top

Though wild rice soup is easier to make in the Instant Pot, you can make it on the stove top instead. Here’s how.

Bring a pot of water to boil over high heat. Add in the wild rice and cook until the rice has burst open and is tender. This will take about 45 to 50 minutes.

As the rice cooks, prepare the veggies and soup base. In a stock pot, melt the butter over medium-high heat and then add the onions, carrots, and celery. Once the onions are translucent in color (about 4 to 5 minutes of cooking), reduce the heat and add in the mushrooms.

Cook the mushrooms for about 15 to 20 minutes or until they have turned brown and have released their moisture into the pot. When the mushrooms are ready, add in the garlic and seasonings and cook for about 1 minute or until they become fragrant. 

Sprinkle the flour on top of the veggies and stir it in to create a very thick sauce. Add in the broth and milk and bring the soup to a boil before reducing heat to a simmer. Simmer for about 15 to 20 minutes or until the soup has begun to thicken.

Once the soup has thickened, add in the spinach and rice. Mix it all together well. 

Garnish with cheese or pepper. Serve with fresh bread or rolls.

Pro tips and tricks

Follow these tips and tricks to make the best soup with wild rice and mushrooms:

  • Soak or rinse the wild rice before cooking
  • Use fresh ingredients for the best flavor
  • Use only 100% wild rice for this recipe for the best results
  • If you need to make this gluten free, you can make the roux substituting cornstarch for the flour. You just need to use 1.5 tbsp of corn starch compared to the flour.
  • To make the soup vegan, use an oil instead of butter and a milk alternative instead of milk.

What variations can I make to this recipe?

There are two easy variations you can make including:

  • Gluten free - use cornstarch instead of flour to make the roux. You will only need half the amount of cornstarch compared to the flour.
  • Vegan - use oil instead of butter and soy or another milk for the milk in the roux.

You could also add additional vegetables to the soup. Carrots work well with the soup. You could also use kale along with the spinach.

You can also serve the soup with cheese on top. Or you could serve the soup with homemade dinner rolls or a loaf of crusty bread.

What rice should I use to make this soup?

You should use 100% wild rice for this soup. If you absolutely have to, you can use a wild rice blend, but they contain brown rice, which will change the texture of the soup.

How can I make this soup vegan?

You can easily make this mushroom soup vegan by:

  1. Substituting an equivalent amount of oil for the butter
  2. Use unsweetened soy, almond, or other plant-based milk instead of milk for the roux

Is this soup gluten free?

No, the soup is not gluten free since it contains flour. You can easily change this if you need to. Instead of using flour, use 1.5 tbsp of corn starch. This will thicken the roux and still create the thick, creamy texture of the soup.

Serving suggestions

Wild rice soup is a hearty soup that is a meal by itself. It is perfect for sending with your family for lunch or as a great tasting dinner.

We often serve the soup with rolls, crusty bread, and some cheese to put on top. You can also serve the soup with croutons on top for some added texture and crunch.

How can I store this soup?

You can store the soup for about 5 to 6 days in an airtight container in the refrigerator. You could also serve it in individual containers if you prefer for an easy lunch option.

Reheat the soup on the stove top over low heat or in a microwave.

You can freeze the soup base for up to 6 month. To do this, make the soup in the Instant Pot, but do not make the roux. If you freeze the soup with the roux, the texture will change. 

When you are ready to serve the frozen soup, let it thaw overnight. Add the soup to a large pot and make the roux in a smaller pot. Once the roux is ready, mix it into the soup and allow it to thicken before serving.

How can I meal prep this recipe?

Yes, you can make the base of the soup ahead of time to make it easier when you are ready to make it. To meal prep the soup, cut the veggies and mix them with the broth, seasonings, wild rice, and mushrooms. Freeze the ingredients in freezer safe bags or containers.

When you want to make the soup, allow the mixture to thaw overnight. Then follow the recipe cooking the soup in the Instant Pot and making the roux.

I always have trouble finding wild rice. Tried a soup one time with a mixture and it came out mushy. Where can I find wild rice without spending $30 for a bag?

Cheryl, I’d say either Amazon or Whole Food or Harris Teeter will have a small pack. Wild rice usually does cost more compared to other rice hut it’s yum. Good luck
