Ingredients

• 1 lb (450g) cauliflower, chopped into florets
• 1 cup (150g) crumbled feta cheese
• ½ cup (120g) sour cream
• 4 cups (950ml) chicken broth
• 1 cup (240ml) milk
• ¼ cup fresh parsley, finely chopped
• 3 tbsp (42g) butter
• ¼ tsp salt
• ¼ tsp dried thyme

Instructions

1. Set your Instant Pot to the “Sauté” function. Once hot, melt the butter in the inner pot.
2. Add the chopped cauliflower florets and sauté for 4-5 minutes, stirring occasionally until they begin to soften slightly.
3. Season with salt and dried thyme, then pour in the chicken broth. Stir to combine.
4. Secure the lid, set the steam release handle to the “Sealing” position, and cook on high pressure for 20 minutes using the “Manual” or “Pressure Cook” button.
5. Once the timer finishes, perform a quick pressure release by carefully moving the steam release handle to the “Venting” position. Once the pin drops, open the lid.
6. Let the soup cool slightly. Carefully transfer the contents of the pot to a high-powered blender. Add the feta cheese, sour cream, and fresh parsley.
7. Blend on high until the soup is completely smooth and velvety. (Alternatively, use an immersion blender directly in the Instant Pot).
8. Pour the blended soup back into the Instant Pot and select the “Sauté” function. Bring the soup to a gentle simmer.
9. Stir in the milk and heat through, but do not let it boil. Taste and adjust seasoning with more salt or pepper if needed. Press “Cancel”.
10. Serve immediately, garnished with extra feta and fresh parsley if desired.
