Instant Pot Basil Zucchini Soup

Soup isn’t just for the colder months! Zucchini soup is one of my favorite ways to still enjoy a nourishing vegetable soup in the spring and summer. With flavors like leek, basil, and lemon, it’s fresh and light, while still being nourishing and comforting.

This soup can easily be made in the instant pot (or on the stove) and can be served lukewarm. It’s dairy-free, AIP, paleo, and whole30.

The Ingredients for the Basil Zucchini Soup

  • Leeks.
  • Zucchini.
  • Chicken broth. You can find quality clean chicken broths via Thrive Market or most grocers or make your own.
  • Basil.
  • Lemon juice.
  • Garlic.
  • Coconut milk. I really like the brand Native Forest.

How to make Zucchini Soup in the Instant Pot

  • Saute the leek and garlic. Set the instant pot to sauté and pour in 2 tbsp of olive oil. Saute for 2-3 minutes or until the leek is slightly softened.
  • Add the zucchini, chicken broth, lemon juice, basil, salt, pepper to the instant pot and stir to combine.
  • Cook in the Instant Pot. Place the lid on the instant pot with the valve sealed. Hit “Manual” and set to high pressure for 8 minutes.
  • Cool and blend. Allow to cool for 15 minutes or so before carefully blending with an immersion blender (or a high-speed blender).
  • Top with coconut milk and fresh basil. Serve lukewarm and enjoy!
