With diced tomatoes, mushrooms, carrots and baby spinach, this lentil wild rice soup is hearty and tasty. It’s a great fall-winter vegan vegetable soup that’s fragrant with garlic, cumin and thyme. Once the soup finishes simmering, I squeeze in fresh lemon juice to add brightness. 

For another lentil soup recipe, try this spicy carrot tomato lentil soup or slow-cooker moroccan lentil stew.

Why You’ll Love This Recipe

It is a lighter, more healthy version of wild rice soup that’s vegan. Classic wild rice soup recipes are creamy and rich with butter, chicken and sometimes heavy cream. The broth in this soup is made with vegetable stock and a small can of diced tomatoes to give it nice acidity.

Including both lentils and rice makes the soup very filling. This is how you get soup to eat like a meal for lunch or dinner. What beans do in chili and other soup recipes is what these additions do in this hearty soup.

During fall and winter, it is always good to have another version of vegetable soup. This one ticks the boxes because it’s simple to make, nutritious, flavorful and freezer-friendly. 

The Ingredients

Ingredients including lentils, rice, onions, carrots, celery mushrooms, seasonings, broth, spinach and lemon.

This is what you need:

  • Wild rice: Try different brands to see which blend you like most. 
  • Green lentils simmer in soups and hold their shape. Do not substitute with red lentils because they will break down in broth. Rinse your lentils with cold water in a strainer before you add them to the soup
  • Onions, celery & carrots are the starting point for building flavors like they are for so many other soup recipes.
  • Mushrooms: You can use white mushrooms, cremini mushrooms or baby bella mushrooms. Brush off the dirt before dicing them.
  • Garlic: Three minced garlic cloves may sound like a lot, but it’s the right amount with the vegetables in the lightly tomatoey broth. They melt right into the olive oil and veggies as you sauté everything.
  • Dried seasonings: The soup is seasoned with a mix of cumin, thyme, red pepper flakes kosher salt and black pepper. If you don’t have thyme, rosemary is another good option.
  • Vegetable broth: It’s best to use low-sodium vegetable broth, so you have full control over the seasoning of the soup, especially salt. If you don’t mind if the soup isn’t vegan/vegetarian, you can use chicken broth instead.
  • Spinach: I stir in baby spinach when the soup finishes simmering. The heat will quickly wilt the leaves. You can use kale, too, depending what greens you have at home. Kale is sturdier, so it will take longer to soften.
  • Lemon: Squeezing in lemon juice adds wonderful brightness to the soup.
  • Parsley: Chopped fresh herbs also give the soup freshness along with the lemon.
  • Olive oil: Use extra-virgin olive oil for the best taste.

How To Make Lentil Wild Rice Soup

1. Sauté the onions, celery, carrots and mushrooms. Heat the oil in a large saucepan or dutch oven over medium high heat. Give them about 4-5 minutes to soften. 

2. Add the minced garlic, cumin, thyme, red pepper flakes, salt and pepper. Sauté everything until fragrant, about 1 minute.

3. Pour in the diced tomatoes, vegetable broth, water and wild rice. Bring the mixture to a boil. Reduce the heat and simmer for 10 minutes. Add the lentils and keep simmering for 20-25 minutes until the rice is cooked and the lentils are tender.

4. Stir in the baby spinach, fresh lemon juice and chopped parsley. The heat from the soup will wilt the greens.

Serving

You can keep it simple and eat this soup with a piece of sourdough or another artisan bread with a good crust. I always like soup with a salad such as this lemony arugula salad, Italian chopped salad, a better than a restaurant house salad or a chickpea cucumber salad

Storage & Leftovers

First, let the soup cool to room temperature. You can store it in an airtight container in the fridge up to 3 days. To save it longer, you can freeze it up to 1 month. If you are going to keep it in the freezer, divide it into smaller portions rather than putting it one big container to make it easier to thaw. Warm it in the microwave or on the stovetop.

Please keep in mind that the longer you store the soup the more the rice and lentils will absorb the broth. Not only will they become softer, but you may need to add water or more broth when you reheat leftovers. Taste it when you have it warmed up in case you need to add seasonings.

This vegan lentil wild rice soup is extra hearty with a mix of carrots, celery, mushrooms, tomatoes and spinach to go with the rice and lentils. It’s finished with lemon juice.

Ingredients 

  • 1 tablespoon olive oil
  • 1 onion, roughly chopped
  • 2 celery stalks, diced
  • 2 carrots, diced
  • 1 cup diced mushrooms
  • 3 garlic cloves, minced
  • 1/4 teaspoon cumin
  • 1/4 teaspoon dried thyme
  • Pinch of red pepper flakes
  • 1 teaspoon kosher salt
  • 1/2 teaspoon black pepper
  • 14.5 ounce can diced tomatoes
  • 4 cups low-sodium vegetable broth
  • 4 cups water
  • 3/4 cup wild rice
  • 3/4 cup green lentils
  • 2 ounces baby spinach
  • Juice of 1 lemon
  • 1 tablespoon chopped parsley

Instructions 

  • Warm the olive oil in a large saucepan or dutch oven over medium high heat. Sauté the onions, celery, carrots and mushrooms until they start to soften, about 4-5 minutes. 
  • Add the garlic, cumin, thyme, red pepper flakes, salt and pepper and sauté for 1 minute until fragrant. 
  • Pour in the tomatoes, vegetable broth, water and wild rice. Bring the mixture to a boil. Reduce the heat and simmer for 10 minutes. 
  • Add the lentils and continue simmering for 20-25 minutes until the rice is cooked and the lentils are tender.
  • Stir in the baby spinach, lemon juice and parsley.

Notes

You cn use chopped kale leaves instead of baby spinach.
Before storing the soup, let it cool to room temperature. Transfer it to an airtight container. You can save it in the fridge for 3 days. To keep it longer, store it in the freezer up to 1 month. If you freeze leftovers, divide them into smaller portions to make it easier to thaw. Reheat it in the microwave or on the stovetop.
The longer you store the soup the more the rice and lentils will absorb the broth. Not only will they become softer, but you may need to add water or more broth when you reheat leftovers. Then taste the warmed soup to see if it needs more salt and/or pepper.

    I doubled the recipe, used a locally grown wild rice/brown rice blend, and added extra seasoning at the end, after the parsley and lemon. It came out beautiful and delicious. Served with a no-flour corn spoon bread–just YUM!
