Would the holidays ever  be complete without mashed potatoes? Creamy, thick, comforting mashed potatoes? I didn’t think so.

If you’ve never roasted garlic before, you are in for something special. While it does take some time in the oven, it’s so easy to do and really transforms a dish. While normally you would use a clove or two of garlic, in this recipe you use two full heads of garlic.

Roasting garlic in the oven gives garlic a milder, sweeter taste than if it’s cooked traditionally on the stovetop. The garlic almost caramelizes and gives a wonderful, nutty aroma and flavor to whatever you put it in. It’s pure MAGIC!

Roasted Garlic in the Oven

Roasting garlic in the oven could not be simpler. All you have to do is cut off the top of the garlic head to expose some of the cloves. Then you drizzle with some olive oil and wrap in aluminum foil. Bake at 400F for 45 minutes to an hour, until the garlic is a deep brown and buttery, soft. You can let it cool for a bit, and then squeeze it out of it’s peel. It comes out so easily.

I know what you’re thinking, is this step necessary? The holidays are busy enough, so roasting a head of garlic is just not in the cards. You guys! You can store roasted garlic for 2 weeks in the refrigerator! You can also freeze it for even longer storage. So no excuses!

But really, if you really, really don’t want to roast garlic.. It’s cool. I still like you. Kind of. Just sauteé 1-2 cloves of minced garlic in a skillet with olive oil for a few minutes to get a little flavor in these mashed potatoes.

What is Brown Butter?

Okay, second majorly big component of this roasted garlic mashed potatoes recipe is the brown butter. If you haven’t done it before, I promise it’s another super simple thing to do. Essentially, brown butter is… well brown butter.

All you do is place butter (or even dairy-free butter) in a saucepan and heat over medium heat until it browns and forks this nutty, brown, silky butter sauce. The milk fat solids fall to the bottom of the pan and get all toasted. It’s also magic. (So much magic in this recipe!)

You can use brown butter in any recipe that calls for melted butter to get a deeper, nutty flavor in your recipes. You can also refrigerate it until it solidifies so you can cream it with sugar for your baked goods. I mean… brown butter chocolate chip cookies? Swoon worthy!

It only takes about 5-10 minutes to brown butter and it’s such a worthwhile step to take in this recipe. Trust me on this one. You can, of course, make it ahead of time and store in the fridge for up to 2 weeks.

Here, we are browning butter and adding in fresh sage leaves while it cooks to infuse our brown butter with sage for our roasted garlic mashed potatoes. Once the butter browns, we remove the sage leaves with a slotted spoon to a plate to dry.

I like to sprinkle with a little salt for some added flavor. The sage leaves get slightly golden and are of course doused in butter, so how could you go wrong there? They’re great for topping the mashed potatoes for serving.

Tips for Making This Garlic Mashed Potatoes Recipe

  • Make the roasted garlic ahead of time to save room in the oven before the holidays. Store in the refrigerator for up to 2 weeks.
  • Make ahead that brown butter. It will store for up to 2 weeks in the refrigerator.
  • Really like to prepare ahead? You can make this whole dish ahead of time and just reheat in the oven. Stir in some warm milk to refresh the potatoes and save a little of the brown butter for topping before serving.
  • Dairy-free or vegan? I’ve got you covered! You can make this whole recipe with dairy-free butter, such as Earth Balance, and non-dairy milk. I’ve tested with unsweetened unflavored (seriously… do not grab that vanilla flavor) almond milk with great results.
  • Since we’re using yukon gold potatoes, you technically do not need to peel them if you don’t want to. Just wash and scrub off any dirt.

To Roast Garlic in the Oven:
