Method
 

  1. These step-by-step instructions will guide you to mashed potato perfection every single time:
Step 1: Roast the Garlic
  1. Preheat your oven to 400°F (200°C).
  2. Slice off the top ¼ inch of the garlic head to expose the cloves.
  3. Place the garlic head on a small piece of aluminum foil, drizzle with 1 teaspoon olive oil, and wrap tightly.
  4. Roast for 40 minutes, or until the cloves are golden and soft.
  5. Remove from the oven and let cool for 10 minutes.
  6. Squeeze the roasted garlic cloves out of their skins into a small bowl and mash into a smooth paste.
  7. Roasting mellows the garlic’s sharpness and infuses the potatoes with a deep, rich flavor.
Step 2: Cook the Potatoes
  1. Place the potatoes in a large pot and cover with cold water.
  2. Add 1 tablespoon of kosher salt to the water.
  3. Bring to a boil over medium-high heat, then reduce to a simmer.
  4. Cook for 15–20 minutes, or until the potatoes are fork-tender.
  5. Drain well and return them to the hot pot to allow excess moisture to evaporate.
Step 3: Warm the Dairy
  1. In a small saucepan, heat the half-and-half and butter together over low heat until the butter melts.
  2. Do not boil — just warm enough to blend smoothly with the potatoes.
Step 4: Mash the Potatoes
  1. Using a potato masher or ricer, mash the potatoes to your desired consistency.
  2. Add the roasted garlic paste and half of the warmed butter mixture.
  3. Stir gently, then pour in the remaining butter and half-and-half, mixing until creamy and smooth.
  4. Season generously with salt and freshly ground black pepper to taste.
Step 5: Adjust & Serve
  1. Taste and adjust seasoning as needed.
  2. For an extra touch of indulgence, drizzle a little melted butter on top before serving.
  3. Garnish with chopped parsley or chives for color and freshness.
  4. Serve warm and enjoy the perfect balance of creamy texture and roasted garlic flavor.

❓ 10 FAQs
1. Why roast the garlic instead of using raw?
Roasting softens the flavor and brings out the garlic’s natural sweetness — no harsh bite, just buttery richness.
2. Can I use Yukon Gold potatoes instead of red potatoes?
Yes! Yukon Golds make an even creamier mash, while red potatoes give a slightly rustic texture.
3. Can I make these ahead of time?
Yes — they reheat beautifully with a splash of milk or cream before serving.
4. How do I prevent gluey mashed potatoes?
Avoid overmixing. Mash gently and add liquids slowly.
5. Can I leave the skins on?
Absolutely! The skins add texture, color, and extra nutrients.
6. How can I make the flavor stronger?
Use two heads of roasted garlic for a bolder flavor or add roasted shallots for sweetness.
7. Can I use regular milk instead of half-and-half?
Yes, but half-and-half gives a richer, creamier consistency.
8. What pairs well with these potatoes?
They’re perfect with roasted chicken, beef short ribs, grilled fish, or vegetable medleys.
9. Can I roast the garlic in advance?
Yes — roasted garlic can be stored in the fridge for up to 1 week or frozen for up to 3 months.
10. Can I add herbs directly into the mash?
Of course! Stir in fresh parsley, thyme, or chives for a pop of flavor and color.
