These Mashed Potatoes with Parmesan, Roasted Garlic, and Fresh Thyme are a rich, creamy side dish full of savory, comforting flavor. Roasted garlic adds sweetness and depth, Parmesan brings nutty richness, and fresh thyme gives an herbal lift—making them perfect for holidays or elevated everyday dinners.

Ingredients

  • 3 pounds Russet or Yukon Gold potatoes
  • 1 whole head garlic
  • 1 tablespoon olive oil
  • 4 tablespoons unsalted butter
  • 3/4 cup heavy cream or whole milk, warmed
  • 1/2 cup freshly grated Parmesan cheese
  • 1 tablespoon fresh thyme leaves, chopped
  • Salt, to taste
  • Black pepper, to taste

Instructions

  1. Preheat oven to 400°F (200°C). Slice the top off a garlic head, drizzle with olive oil, wrap in foil, and roast for 35–40 minutes until soft and golden.
  2. Peel and chop potatoes into chunks. Boil in salted water for 15–20 minutes, or until fork-tender.
  3. Drain the potatoes and return to the pot. Heat briefly over low heat to remove excess moisture.
  4. Squeeze roasted garlic cloves from their skins and mash into a paste.
  5. Mash the potatoes with butter and warm cream or milk.
  6. Stir in roasted garlic paste, grated Parmesan, and chopped fresh thyme.
  7. Season with salt and pepper to taste. Serve hot.

Notes

  • For extra richness, stir in a few tablespoons of cream cheese.
  • Smoked paprika or aged Gouda can add depth and a smoky twist.
  • Use half-and-half or vegetable broth as a milk substitute for different textures or dietary needs.
  • Dried thyme can be substituted—use 1/3 the amount of fresh.
  • Freshly grated Parmesan melts better and has superior flavor, but pre-grated works in a pinch.
