Ingredients
  

  • 1 cup quinoa rinsed and drained
  • 2 tablespoons olive oil
  • 1 large onion diced
  • 3 cloves garlic minced
  • 2 carrots diced
  • 2 celery stalks sliced
  • 1 red bell pepper diced
  • 1 zucchini diced
  • 1 can 14.5 oz diced tomatoes
  • 6 cups vegetable broth low-sodium preferred
  • 2 bay leaves
  • 1 teaspoon dried thyme
  • 1 teaspoon dried oregano
  • ½ teaspoon red pepper flakes optional, for heat
  • 2 cups fresh spinach or kale roughly chopped
  • 1 tablespoon lemon juice
  • Salt and pepper to taste
  • ¼ cup fresh parsley chopped (for garnish)

Instructions
 

  • Prepare the quinoa by rinsing it thoroughly in a fine-mesh sieve under cold water until the water runs clear. This removes the natural bitter coating called saponin.
  • Heat olive oil in a large pot over medium heat. Add the diced onion and cook for 3-4 minutes until translucent.
  • Add garlic and cook for 30 seconds until fragrant, being careful not to burn it as this will create a bitter taste.
  • Add the carrots, celery, and bell pepper to the pot and cook for 5 minutes, stirring occasionally, until vegetables begin to soften.
  • Stir in the diced zucchini and canned tomatoes with their juice, cooking for another 2 minutes to incorporate flavors.
  • Pour in the vegetable broth and add bay leaves, thyme, oregano, and red pepper flakes if using. Bring the mixture to a boil.
  • Add the rinsed quinoa to the boiling soup, then reduce heat to a simmer. Cover and cook for 15-20 minutes, or until quinoa is tender and has sprouted its little “tail.”
  • Stir in the chopped greens (spinach or kale) and cook for 2-3 minutes more until wilted.
  • Remove from heat and add lemon juice, which brightens all the flavors. Season with salt and pepper to taste.
  • Remove bay leaves before serving. Ladle into bowls and garnish with fresh parsley.

Notes

  • For a time-saving option, use pre-washed quinoa which doesn’t require rinsing.
  • This soup thickens considerably as it sits because the quinoa continues to absorb liquid. If making ahead or storing leftovers, you may need to add additional broth when reheating.
  • For a protein boost, add a can of drained and rinsed white beans or chickpeas when you add the vegetable broth.
  • This soup freezes beautifully for up to 3 months in airtight containers. Thaw overnight in the refrigerator before reheating.
  • For deeper flavor, consider using homemade vegetable stock instead of store-bought broth.
