Ingredients

  • 3 lbs potatoes
  • 1 head garlic
  • 1 stick butter
  • 3/4 cup whole milk
  • 1/3 cup sour cream
  • 10-12 sage leaves
  • 3-4 thyme sprigs
  • 1 tsp salt
  • olive oil for roasting the garlic

Instructions

  • Preheat oven to 400°F. Slice the top off a whole head of garlic to expose the cloves. Drizzle with olive oil and season with salt, wrap in foil, and roast for 35-40 minutes, until soft and golden. Let cool slightly, then squeeze out the garlic cloves.
  • Peel and chop potatoes into large chunks. Place in a large pot and cover with cold, salted water. Bring to a boil and cook 15-20 minutes, until fork tender. Drain and return potatoes to the warm pot.
  • In a medium frying pan, melt butter over medium heat. Add sage leaves and thyme sprigs. Continue cooking, stirring occasionally, for 5-7 minutes, until the butter turns golden brown and herbs become crisp. Remove herbs and set aside for garnishing. Reserve the butter.
  • Add roasted garlic, sour cream, milk, and half of the brown butter to the potatoes. Mash until smooth and creamy, adding more milk if needed. Season with salt to taste.
  • Transfer mashed potatoes to a serving dish. Pour remaining brown butter over the top and garnish with the crispy sage and thyme. Serve warm.
