- 1 head garlic
- extra virgin olive oil
- 4 pounds russet potatoes, peeled and quartered
- 2 cups heavy cream
- 2 cups whole milk
- 8 fresh sage leaves
- 3 sprigs fresh thyme
- 6-8 tablespoons salted butter, at room temperature
- kosher salt and black pepper
- Preheat the oven to 400° F.
- Slice off the top portion of the garlic head to expose some of the cloves. Place the garlic on a piece of foil. Drizzle with olive oil, wrap it up, and bake for 40-55 minutes, until deeply golden and very soft.
- Let the garlic cool, then squeeze out the cloves.
- Meanwhile, In a large dutch oven, combine the potatoes, heavy cream, milk, sage, and thyme. Bring to a gentle boil over medium heat and cook 20-25 minutes, until the potatoes are fork-tender.
- Drain the potatoes, reserving all of the cream. Discard the thyme and sage. Press the potatoes and roasted garlic cloves through a potato ricer. Then add them back to the warm pot. Alternately, you can add the potatoes back to the pot and mash with a potato masher.
- Over low heat, add 1 1/2 cups of the reserved cream and the butter. Continue to add more of the cream until your desired consistency is reached. Season the potatoes with salt and pepper.
- If desired, brown a little butter with sage or thyme and swirl into the potatoes before serving. Serve warm and creamy.
