Ingredients

For the soup

For the cashew cream

  • ¾ cup raw cashews soaked in water for at least 4 hours
  • ¾ cup filtered water
  • 1 lemon juiced
  • ½ teaspoon kosher salt

For the sourdough croutons

  • 2 slices gluten-free sourdough bread
  • 1 tablespoon olive oil or avocado oil
  • Salt + garlic powder to taste

Instructions

  • For the soup: In a large saucepan or soup pot, heat the oil over medium heat. Add the diced onion and cook for 5-7 minutes, or until translucent. Add the garlic and cook for one more minute, or until fragrant.
    2 tablespoons olive oil, 1 yellow onion, 3 garlic cloves
  • Add the vegetable broth and bring to a boil. Add in the broccoli, salt, garlic powder, onion powder, and turmeric and cook for 5-7 minutes or until the broccoli is tender.
    5 cups low-sodium vegetable broth, 6 cups (about 12 oz.) broccoli florets, 1 teaspoon sea salt, ¾ teaspoon garlic powder, ½ teaspoon onion powder, ¼ teaspoon turmeric powder
  • Remove a heaping cup of the cooked broccoli from the liquid with a slotted spoon and place in a separate bowl for now.
  • Put 1/2 cup soaked cashews, nutritional yeast, and tapioca starch in a high-powered blender (I used my Vitamix) and add the soup from the saucepan. Blend until smooth. You may need to blend in two batches if your blender is on the smaller side. Alternatively, you can use an immersion blender.
    ½ cup raw cashews, ¼ cup Bob’s Red Mill nutritional yeast, 2 teaspoons tapioca flour
  • Add in the broccoli you had removed and the cooked quinoa. Pulse slightly just to break up the broccoli slightly (don’t blend it in completely if you want some texture, like I prefer) and incorporate the quinoa.
    1 cup cooked Bob’s Red Mill quinoa
  • Return to the saucepan and bring to a simmer to let the tapioca flour thicken the soup slightly. You can simmer for up 5-10 minutes longer, uncovered, if you’d like it thicker.
  • Remove from heat, stir in the juice of one lemon, and serve with cashew cream, sourdough croutons, and microgreens!
    1 lemon
  • For the cashew cream: Blend the soaked cashews with the filtered water, lemon juice, and kosher salt until completely smooth. Add salt to taste.
    ¾ cup raw cashews, ¾ cup filtered water, 1 lemon, ½ teaspoon kosher salt
  • For the croutons: Preheat the oven to 375°F and line a baking sheet with parchment paper or a silicone baking liner.
    2 slices gluten-free sourdough bread, 1 tablespoon olive oil, Salt + garlic powder
  • Cut the bread into 1/2-inch cubes. Place in a bowl and toss with the oil, salt, and garlic powder.
  • Place on the prepared baking sheet and cook for 10-15 minutes, or until toasted to your desired crunchiness.

Notes

You can soak the cashews all at once; there's no need to soak them separately. You can also pour boiling water over them and soak for just an hour or so, if you’re short on time.
Nutritional info does not include croutons because it varies by bread type.
