Roasted Garlic Mashed Potatoes

These roasted garlic mashed potatoes are like mashed potatoes gone to finishing school with sour cream, Parmesan, and sweetly caramelized onions suffused with red wine. Quite possibly the best mashed potatoes we've ever had.

  • 5 1/2 to 6 pounds Yukon gold potatoes, peeled, if desired, and cut into quarters

US - Metric

Instructions

  • Crank the oven to 425°F (218°C).
  • Remove the loose papery skin from the garlic and cut off the top third of the bulb. Brush the bulb with oil. Wrap the bulb in foil and roast it until tender and sweetly caramelized, 30 to 45 minutes, depending on the size of the bulb. Let cool.
  • Add a tablespoon or two of salt to a large pot of cold water. Plonk in the potatoes and bring to a boil. Lower the heat to a simmer, cover, and cook until tender when pierced with a fork, 15 to 20 minutes.
  • Drain the potatoes and scoop them in a large bowl.
  • Squeeze the cooled, roasted garlic onto the potatoes, and add the butter, sour cream, cheese, and milk. Mash until the taters are as chunky or smooth as you like, adding more milk if needed.
  • Taste and season liberally with salt and pepper. Serve immediately.

Notes

  1. Roast extra garlic-- Roast a couple of extra garlic heads while making these potatoes. Extra roasted garlic can be kept in a sealed container in the fridge for up to 2 weeks. Toss it with sautéed broccoli rabe for an easy side dish, stir it into mayonnaise or horseradish, or squeeze it over your homemade white pizza.
  2. Ricing the potatoes--For very smooth mashed potatoes, use a ricer instead of a potato masher.
  3. Storage and reheating--Store leftover mashed potatoes in a sealed container in the fridge for up to 4 days. To reheat leftover potatoes, place them in a double boiler and warm over low heat, stirring in more milk, if needed, to make them smooth and creamy.
