Start by washing the head of cauliflower under cold water. Remove the leaves and cut the cauliflower into florets. This will help it cook evenly and allow for easier blending later on.
In a large pot, bring water to a boil. Add a pinch of salt and carefully add the cauliflower florets. Cook for about 10-12 minutes, or until the cauliflower is fork-tender.
Once cooked, drain the cauliflower using a colander and allow it to cool for a few minutes. This step is crucial as it prevents excess moisture from making the whipped cauliflower watery.
In a blender or food processor, combine the cooked cauliflower, Greek yogurt, large egg, half of the Parmesan cheese, chopped chives, kosher salt, and black pepper. Blend until smooth and creamy.
Give the whipped cauliflower a taste. Feel free to adjust the seasoning, adding more salt, pepper, or chives according to your preference.
Transfer the whipped cauliflower to a serving bowl. Sprinkle the remaining Parmesan cheese on top, and for an extra touch, dust with paprika and garnish with parsley or more chives. Serve immediately and enjoy!
