How to make Cacio e Pepe Mashed Potatoes
- Cook the potatoes: Place whole potatoes in a large pot and fill with water. Season generously with salt. Bring to a boil and cook for 30 minutes or until a sharp knife can easily be inserted. Drain the potatoes then allow to cool slightly. Peel the potatoes and discard the skins.
- Mash the potatoes: Add the milk, butter, Parmesan, salt, pepper and garlic powder and mash the potatoes to your preferred texture. Alternatively, use a potato ricer and stir in the remaining ingredients. Adjust seasoning if necessary.
- Serve: Transfer the mashed potatoes to a serving dish then add a knob of butter. Garnish with finely chopped parsley (or chives) and a generous grating of Parmesan cheese.
Making ahead and freezing
- Make ahead: The potatoes can be mashed a day in advance and kept covered in the fridge a day in advance.
- Freezing: Allow mashed potatoes to come to room temperature then transfer to a freezer-safe dish. Press a piece of parchment paper onto the surface of the potatoes, cover and freeze for up to 3 months. Thaw completely before reheating.
How to reheat mashed potatoes
Transfer the cold potatoes to a pot and reheat over medium-low heat. You might need to add a splash of milk. Reheat, stirring regularly, until hot throughout.
