Ingredients

1 Head Garlic
Extra Virgin Olive Oil
4 Pounds Yukon Gold or Russet Potatoes peeled and quartered
2 Cups Heavy Cream
2 Cups Whole Milk
8 Fresh Sage Leaves
3 Sprigs Fresh Thyme
6-8 Tbsp Salted Butter at room temperature
Kosher Salt and Black Pepper

Instructions

Preheat Oven: Heat your oven to 400°F.
Roast Garlic: Slice the top off the Garlic head to expose the cloves. Place it on foil, drizzle with Olive Oil, wrap it up, and bake for 40-55 minutes until golden and soft. Cool and squeeze out the Garlic cloves.
Cook Potatoes: In a large Dutch oven, combine Potatoes, Heavy Cream, Milk, Sage, and Thyme. Bring to a gentle boil over medium heat and cook for 20-25 minutes, until Potatoes are fork-tender.
Drain and Mash: Drain the Potatoes, reserving the cream mixture. Discard the Sage and Thyme. Press the Potatoes and Roasted Garlic through a potato ricer or mash with a masher.
Add Cream and Butter: Over low heat, add 1 1/2 cups of the reserved cream and Butter to the Potatoes. Stir in more cream until you reach your desired consistency. Season with Salt and Pepper.
Optional Garnish: For extra flavor, brown a bit of Butter with Sage or Thyme and swirl it into the Mashed Potatoes before serving.
