  • 3 pounds potatoes (Yukon Gold)
  • 1 bulb garlic
  • 4 tablespoons salted butter
  • ¼ cup heavy cream (double cream)
  • salt and pepper to taste


  • Preheat the oven to 400F / 205c.
  • Peel and discard the outer layers of the garlic bulb, and cut the top off of the bulb.
  • Drizzle with oil, cover with foil and place in the oven for 30 minutes until it is soft. Set to one side.
  • While the garlic is roasting, peel and quarter the potatoes.
  • Place the potatoes in a large pot of salted water and bring to the boil.
  • Boil for about 15 minutes until they are fork tender. Let them steam for 5 minutes.
  • Heat the cream gently in a pot or heat in the microwave, just to warm it through.
  • Place the potatoes back into the pot, add in the warm cream and butter and squeeze in the roasted garlic.
  • Mash everything together, taste and adjust the seasoning and serve. Garnish with fresh parsley if you like.


  • Salt the water that you boil the potatoes in. As they boil, the potatoes will absorb the seasoning leading to a more flavorful dish, and you won't have to add as much extra salt at the end.
  • Add the potatoes to cold water and bring them up to the boil. If you add the potatoes to already boiling water, the outsides will cook much quicker than the middles.
  • Don't over work the mash. Stop as soon as everything is combined. If you over mash them, they can become gluey rather than light and fluffy. If you have a potato ricer, then definitely use that!
  • Taste for seasoning before serving and adjust as needed.
  • If making ahead of time, let the garlic roasted mashed potatoes cool completely before storing.
