Creamy, cheesy Instant Pot Broccoli Zucchini Cheddar Soup is a healthy, wholesome take on the classic.

Ingredients

Scale
  • 2 tablespoons butter
  • 1 small sweet or yellow onion, chopped
  • 1 carrot, chopped
  • 2 medium zucchini, chopped
  • 1 teaspoon dried thyme
  • ¼ teaspoon nutmeg
  • ¼ teaspoon cayenne pepper
  • 1 teaspoon salt
  • ¼ teaspoon black pepper
  • 3 cups chicken or vegetable broth
  • 12 ounce bag of broccoli florets (or about 5 cups broccoli florets)
  • 1 cup milk (skim, 1%, 2%, or whole)
  • 2 cups extra sharp cheddar cheese

Instructions

  1. Select saute on the pressure cooker pot and add butter.
  2. When melted, add onions and saute 3 minutes until they start to soften.
  3. Add carrots, zucchini, thyme, nutmeg, cayenne pepper, salt, pepper, and broth.
  4. Place a steamer basket inside the pot and top with the broccoli.
  5. Secure the lid and turn pressure release knob to a sealed position.  Cook at high pressure for 5 minutes.
  6. When cooking is complete, use a quick release.
  7. Remove the steamer basket.  Add about half of the broccoli back to the pot.
  8. Use an immersion blender to blend soup until completely smooth.  Alternatively you can pour the mixture into a high speed blender and puree until smooth.
  9. Select saute.  Add milk and cheese and stir until melted and smooth.
  10. Stir remaining broccoli into the soup.
  11. Serve hot topped with homemade croutons, crackers, and/or cheese.

Notes

  • If you want the soup extra chunky, do not puree any of the broccoli into the soup.  Simply stir it in once you’ve blended the rest of the soup with the milk and cheese.
  • If you want a completely smooth soup, add the broccoli to the rest of the ingredients (skipping the steamer basket step).
  • This soup is perfect for a bread bowl!
  • Homemade croutons are delicious in this soup.  I provide directions for homemade croutons in this French Onion Soup recipe.
