  • 1 large head cauliflower
  • 2 medium potatoes
  • 2 ½ cup vegetable broth (or water + a bouillon cube)
  • ½ cup heavy cream
  • ½ cup shredded cheddar cheese
  • 1 onion
  • 3 garlic cloves
  • 1 teaspoon olive oil
  • ¼ teaspoon salt
  • ¼ teaspoon pepper
  • teaspoon nutmeg


  • Heat up olive oil in your Instant Pot on the SAUTE setting.
    1 teaspoon olive oil
  • Sauté diced onion and finely diced garlic for a few minutes until soft and translucent. Press cancel to turn the pressure cooker off.
    1 onion, 3 garlic cloves
  • Peel and dice the potatoes into 1-inch chunks. Cut the cauliflower into florets.
    2 medium potatoes, 1 large head cauliflower
  • Add potatoes, cauliflower, vegetable stock and seasoning to the Instant Pot. Use a wooden spoon or spatula to scrape the bottom of the pot to loosen up any stuck pieces of onion.
    2 ½ cup vegetable broth, ¼ teaspoon salt, ¼ teaspoon pepper, ⅛ teaspoon nutmeg
  • Seal the lid, and cook on PRESSURE COOK or MANUAL setting, set the timer to 8 minutes.
  • Turn the valve to manually release the pressure as soon as the timer is up. Remove the lid.
  • Use an immersion blender or hand blender to blend the soup smooth.
  • Optionally, add shredded cheese and cream to the soup. Add any additional seasoning to taste, and serve.
    ½ cup heavy cream, ½ cup shredded cheddar cheese



  • Store leftovers in a refrigerator for up to 3 days. Reheat in a microwave or on the stove top, and serve warm.
  • If you don't have an immersion blender available, you can puree the soup in a regular stand blender. You will have to do this in multiple batches to prevent overfilling the blender.
  • You can omit or reduce the cheese, cream and potatoes. This will make the soup lighter and better suited for several dietary requirements.
