How To Make Perfect Mashed Potatoes.

The best garlic mashed potatoes begin, obviously with the best homemade mashed potato recipe. What do we look for in our mashed potatoes?

  • Fluffy. Airy, whipped and light—never dense or gummy.
  • Ultra-creamy. Thanks, butter.
  • Perfectly seasoned. Not too salty, not too bland.

What Are The Best Potatoes to Mash?

For creamy, mashed potatoes, we love to use russet potatoes. They are our favorite kind of potatoes for mashing as they are starchier than waxed potato varieties (like Yukon Golds). This means fluffier potatoes (so long as they aren’t overcooked!) in the end.

  1. Roast your garlic.
  2. Add your peeled potatoes and bay leaves to large pot of cold water and bring to a boil. Cook until fork tender and drain well, removing the bay leaves.
  3. Peel your roasted garlic and add to the boiled potatoes. Use a ricer or masher to incorporate all that garlic flavor into your homemade mashed potatoes and mash until smooth.
  4. Heat your butter and milk in a small saucepan, then incorporate into the potatoes.
  5. Salt and pepper to taste.

How To Roast Garlic?

Roasting garlic takes this assertive allium from spicy and sharp to pure caramelized sweetness. In addition to mixing it into mashed potatoes, we love to serve it as part of a cheese platter, toss it into pasta, and even spread it straight onto good, crusty bread. Here’s how to roast garlic:

  • Preheat your oven to 400°F.
  • Peel off the loose papery husk on the outside of the garlic head.
  • Slice off the top to reveal the tops of the raw cloves.
  • Drizzle with olive oil and wrap the head of garlic in foil.
  • Roast until carmel-colored and tender, about 40 minutes.
  • Squeeze onto bread, into mashed potatoes, or just straight into waiting mouths.

How Long To Boil Potatoes for Mashed Potatoes?

Boiling russet potatoes for making mashed potatoes is an art unto itself. Here’s how to do it with ease:

  1. Peel your potatoes and cut them into, two-inch pieces so they cook quickly and and uniformly.
  2. Add the potatoes to a large pot of salted water.
  3. Turn the heat to high and bring the water to a boil. Boil them for about 20 minutes, or until just fork-tender. Take care to not overcook them. If they cook too long, all of that pleasant starch we admire so much about the russet potato will go wild, and you’ll be left with potato paste.
  4. Drain the potatoes and return them to the pot.
  5. Over the lowest heat setting, allow the potatoes to dry out completely. Dry potatoes are better able to absorb that lucious milk and butter.

Tips for Making Mashed Potatoes.

This is inherently a simple side dish, but a little bit of extra know-how will ensure that your potatoes come out perfectly:

  • Ricing your potatoesbefore you add your warm dairy helps get them smoother without over processing them.
  • Speaking of warm dairy—don’t add your dairy straight from the fridge. The shock of the cold fat will negatively alter the texture of your potatoes.
  • Using an electric mixer can be tricky. If you decide to go this route be careful not to overmix, or those starches will activate and you’ll be left with a sticky paste.
  • If you really want to go for broke, try replacing half of the milk with heavy cream.
  • Don’t be afraid to season your mashed potatoes. Salt is this homemade roasted garlic mashed potato recipe’s best friend. Salt, then taste, then salt again if necessary.
  • If you’d like to keep it simple, our Classic Mashed Potatoes are the way to go.

How To Keep Mashed Potatoes Warm.

To keep your mashed potatoes warm before eating (or to reheat if they’ve been made ahead) we recommend using a double boiler. Warming your potatoes using this method of indirect heat will help prevent them from drying out or becoming overworked. Don’t have a double boiler? No worries! Just simmer water on the stove and place potatoes in a heat resistant bowl atop the pot. Stir occasionally and until the roasted garlic mashed potatoes are warmed through.

Roasted Garlic Mashed Potatoes

  • Serves: 6
  • Prep Time:  20 min
  • Cook Time:  35 min
  • Calories: 456


  • 2 heads garlic
  • 1 tablespoon extra-virgin olive oil
  • 3 pounds russet potatoes, peeled and diced into 2-inch pieces
  • 3 dried bay leaves
  • 4 teaspoons sea salt, plus more to taste
  • 1 cup unsalted butter (2 sticks)
  • 1 cup whole milk
  • Freshly cracked black pepper


  1. Preheat the oven to 400°F with a rack in the center position.

  2. Slice off the tops of the garlic and drizzle with the olive oil. Wrap the garlic in foil and place, seam side up, on the center rack. Roast until caramelized and tender, about 40 minutes.

  3. Fill a large pot with water and add the potatoes, bay leaves and 3 teaspoons of the salt. Bring to a boil over high heat, then reduce the heat to low and simmer until the potatoes are fork tender, about 15 minutes. Drain.

  4. Return the potatoes to the pot. Discard the bay leaves.

  5. Using a potato ricer or masher, mash the potatoes. Once the garlic has cooled enough to handle, gently squeeze the roasted garlic cloves into the pot with the mashed potatoes and mash to combine.

  6. Place the butter, milk and remaining salt in a small saucepan. Cook over medium-low heat until the butter has melted and the mixture is hot, but not boiling. Pour the mixture into the potatoes, stirring quickly with a large spoon until fully absorbed. Season with salt and pepper to taste.

  • Terri

    Can you make these ahead? How long / any tips on reheating to serve. Thanks!

    We think they are best served fresh.

  • Ken

    Can you use heavy cream instead of milk?

    That should work fine!

  • Neens

    Can you you different types of potatoes? I only have red skin potatoes but I really want to try this recipe!

    We haven't tested with red but it should be fine!

  • Sara

    You are using unsalted butter correct? Then adding salt as needed?


    Yes! So that you can control the saltiness, unsalted is best. Then simply add salt to taste.

  • Cloey

    Seems like a lot of garlic, does this overtake the potatoes?

    Nope. It's mild and lovely!

  • Victoria

    I’m newer to cooking and this recipe was amazing and easy to follow! Turned out great.

    Thanks Victoria, well done!
