What you will need

This recipe uses 6 simple ingredients that you can find at any grocery store:

  • 1.5 cups red lentils rinsed
  • 2 tsp spirulina powder
  • 3.5 cups vegetable broth
  • 2 cups fresh spinach
  • 1 tsp garlic powder
  • 1 tbsp fresh lemon juice

Step by step instructions

Step 1: Cook the Lentils

Combine red lentils with vegetable broth in a medium pot over medium-high heat. Bring to a boil, reduce heat, and simmer uncovered until lentils are completely tender and beginning to break down into a creamy consistency.

Step 2: Add the Spinach

Stir fresh spinach into the hot lentil mixture and cook for just 1 to 2 minutes until fully wilted. The heat of the soup will wilt the spinach perfectly without overcooking it.

Step 3: Blend Until Smooth

Use an immersion blender to blend the soup directly in the pot until completely smooth and creamy. Alternatively transfer to a countertop blender in batches, being very careful with the hot liquid.

Step 4: Add Spirulina and Serve

Remove the pot from heat and stir in the spirulina powder and fresh lemon juice. Do not boil the soup after adding spirulina as heat can degrade its nutritional value. Season with salt and serve immediately.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • spirulina powder → chlorella powder for a similarly protein-rich but milder flavored green supplement
  • fresh spinach → frozen spinach thawed and squeezed dry works equally well in this blended soup

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Boiling the soup after adding spirulina which destroys many of its heat-sensitive proteins and beneficial compounds
  • Adding too much spirulina which can make the soup taste strongly of the ocean in an unpleasant and overpowering way
