This extra creamy garlic mashed potatoes recipe features a whole head of slow-roasted garlic for unbeatable depth and butteriness. There is something so comforting about a bowl of fluffy mashed potatoes, but the golden roasted garlic takes it to new heights. I make these every holiday but you will find me whipping them up anytime I want to treat my family to a memorable meal—because once you taste them, you will find excuses to make them again and again.

The first time I made these potatoes it was all about impressing my in-laws at Thanksgiving. Now my kids just ask for them whenever we roast chicken—turns out no one can resist that roasted garlic aroma wafting through the kitchen.

Ingredients

  • Whole head of garlic: Roasting makes the flavor subtle and buttery Choose garlic bulbs that feel firm and heavy with tight skins
  • Olive oil: Coats the garlic to help it roast evenly Choose extra virgin for the best flavor or use neutral oils like avocado if you prefer
  • Russet or Yukon Gold potatoes: Both mash beautifully and give you fluffy or creamy results Look for potatoes with smooth skin no green patches or sprouting
  • Butter: Provides richness and helps create a luscious texture Use high-quality butter for the best flavor
  • Heavy cream: Makes the mashed potatoes silky Use cream warmed to room temperature so it blends easily
  • Salt and black pepper: Essential to balance flavors Use flaky sea salt or kosher salt for seasoning

Step-by-Step Instructions

Prep the Garlic:
Remove just the outer layers of the garlic head leaving skins of the individual cloves intact Slice off about a quarter inch from the top Keep the garlic whole
Roast the Garlic:
Drizzle the exposed cloves with olive oil Wrap the whole head in foil Place on a baking sheet and roast in a 400 degree oven for about 35 to 40 minutes The garlic should be soft and bronzed Let cool until safe to handle
Cook the Potatoes:
Peel if desired and chop potatoes into even chunks Place in a large pot and cover with cold salted water Bring to a boil and simmer until completely fork tender about 15 to 20 minutes Drain thoroughly then return them to the empty pot over low heat for a couple of minutes This dries out excess water
Mash the Potatoes:
Squeeze the roasted garlic out of its peels directly into the pot with potatoes Add butter in chunks and pour in warmed heavy cream Mash by hand or with an electric mixer until as smooth as you like For ultra fluffiness do not overwork Use less cream for chunkier potatoes
Season and Serve:
Taste and add salt and pepper Mash again just to combine Serve immediately with extra butter and a sprinkle of fresh herbs if you want

My favorite part of this recipe is squeezing golden cloves of roasted garlic into the pot—your kitchen will smell incredible I still remember the first time my daughter helped and giggled at the “garlic paste” She now calls them magic potatoes

Ingredient Substitutions

You can swap heavy cream for evaporated milk or even whole milk for a lighter version If you are out of fresh garlic try a smaller amount of pre-roasted garlic paste found in some markets You can use red potatoes for a more rustic chunky mash

Steps to Prepare
