Make rich, silky-smooth garlic mashed potatoes that are buttery and fluffy. This easy recipe uses roasted garlic for deep flavor, perfect as a side dish for weeknight meals or holiday feasts.

Ingredients

Scale
  • 3 lbs Russet potatoes, peeled and quartered
  • 1 whole head garlic
  • 3 tablespoons olive oil
  • 1/2 cup heavy cream, warmed
  • 1/4 cup unsalted butter, softened
  • 2 tablespoons sour cream
  • 1 teaspoon salt, or to taste
  • 1/2 teaspoon black pepper, or to taste
  • 1/4 teaspoon garlic powder (optional, for extra flavor)

Instructions

  1. Preheat your oven to 400°F (200°C). Slice the top off the head of garlic to expose the cloves. Drizzle with olive oil and wrap tightly in aluminum foil. Roast for 30 to 35 minutes, or until the cloves are soft and golden brown. Let cool slightly.
  2. Place the peeled and quartered potatoes in a large pot and cover with cold, salted water. Bring to a boil over high heat. Reduce heat to medium and cook for 15 to 20 minutes, or until the potatoes are fork-tender.
  3. Drain the potatoes completely. Return them to the hot, empty pot over low heat for 1 minute, shaking occasionally, to dry out any excess moisture. This step helps create fluffy potatoes.
  4. Squeeze the soft, roasted garlic pulp out of the skins into a small bowl. Mash the roasted garlic with a fork until smooth.
  5. Add the softened butter, warmed heavy cream, sour cream, roasted garlic pulp, salt, pepper, and optional garlic powder to the potatoes.
  6. Mash the potatoes using a potato masher or a ricer until you reach your desired consistency. For the silkiest smooth potatoes, use a potato ricer. Avoid overmixing, which can make them gluey.
  7. Taste and adjust salt and pepper as needed. Serve immediately as a buttery potato side dish.

Notes

  • For the creamiest texture, warm the heavy cream before adding it to the potatoes. Cold liquid prevents smooth incorporation.
  • Use starchy potatoes like Russet or Yukon Gold for the best fluffy results.
  • If you prefer a less intense garlic flavor, start with half the roasted garlic and add more to taste.
