Prep Time 15 minutes
Cook Time 20 minutes
Total Time 35 minutes

Ingredients
 
 

  • 4 medium potatoes peeled and cubed
  • 1 medium head cauliflower cut into florets
  • 1 medium onion diced
  • 4 cloves garlic minced
  • 4 cups vegetable broth
  • 1 cup cashew cream unsweetened; or substitute full-fat coconut milk
  • 2 tablespoons olive oil
  • 1 teaspoon dried thyme
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ¼ teaspoon nutmeg

Method
 

  1. Set the Instant Pot to saute mode and heat the olive oil. Add the onion and cook until translucent, about 3 minutes, then add the garlic and cook for 30 seconds.
  2. Add the potatoes, cauliflower, vegetable broth, thyme, salt, pepper, and nutmeg.
  3. Seal the lid and pressure cook on high for 8 minutes. Allow a natural release for 5 minutes, then quick release the remaining pressure.
  4. Stir in the cashew cream, then blend until smooth using an immersion blender.
  5. Adjust the seasoning to taste. If the soup is too thick, thin it with a little more broth.

Substitutions: Cashew cream keeps the soup neutral and dairy-free; full-fat coconut milk also works for a slightly richer result. Use a certified gluten-free broth to keep it gluten-free.
Storage: Store in an airtight container in the fridge for up to 4 days, or freeze for up to 3 months.
Reheating: Warm gently over low heat, stirring, and loosen with a splash of broth if needed.
Note: Nutrition is recalculated for the dairy-free cashew-cream swap and is approximate.
