Wash the cauliflower, remove the leaves, and cut off the thicker part of the stem. Set the Instant Pot to saute for 2 minutes. Add half of the butter and saute the garlic until fragrant. It should only be slightly brown (take care not to burn), then add the water or stock.
2 tablespoon unsalted butter, 4 cloves garlic, 2 cups low-sodium vegetable stock
Next, place the whole cauliflower head (no need to slice or chop) on the trivet, place it inside the Instant Pot and close the lid. The Instant Pot should make a beeping sound, to indicate it is properly closed or sealed). Turn the valve to SEAL and program it to pressure cook for 5 minutes, under high pressure.
1 head cauliflower
Once the cooking time is over, turn the valve to QUICK RELEASE and open the lid once all the pressure has been released. The cauliflower should be fork tender, if not then simply increase the pressure cooking time by a further 2 minutes. Carefully lift the trivet from the Instant Pot and transfer the cauliflower to a bowl. Reserve any leftover broth for use in making other dishes, such as soups and stews.
Let the cauliflower rest and cool slightly (about 5-10 minutes), before processing. This will allow it to release excess moisture. Also, ensure that you properly drain any excess liquid before blending or processing.
Next, use an immersion blender to process until smooth and creamy (you can further drain any excess water at this point as well, remember, we want to avoid having soggy cauliflower mash)! Add the Greek yogurt, cream cheese, Parmesan cheese, and cheddar cheese. Slowly combine, making sure everything is properly incorporated. Add the remaining butter, season with salt and pepper then combine.
¼ cup Greek yoghurt, ¼ cup cream cheese, ⅓ cup parmesan cheese, 1 cup cheddar cheese, ½ teaspoon salt and black pepper respectively, 2 tablespoon unsalted butter
