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.
