Recipe Ingredients

All ingredients for this recipe are shown in the pic below and special notes are made in this bulleted list to assist you.

Ingredients shown: Yukon Gold potatoes, butter, garlic, milk, and russet potatoes.

Potatoes. I recommend a 50/50 mix of Russet and Yukon Gold potatoes. Russets are light and fluffy. They hold less water than other potatoes making them not only perfect for homemade gnocchi but also great for mashing. The downside is they lack the taste and creaminess of a Yukon Gold potato. For this reason, I really like the combination of the two.

How to make it

Begin by placing 12 cloves of garlic in foil. (Photo #1)

Wrap it tight, place on a baking tray, and bake for 40 minutes at 375f on the middle rack in the oven. Note: To save time you can roast garlic days in advance and store it in the fridge. (Photo #2)
Peel the potatoes and quarter. Cut out any bad spots. For this recipe, we use half russets and half Yukon Gold potatoes. You can use all of the same type or a mix depending on availability, and personal preference. (Photo #3)

Place the cleaned, peeled, and quartered potatoes into a large pot and fill with cold water at least 2 inches above the potatoes. Bring the pot to a boil, add in two tablespoons of kosher salt and give it a stir to incorporate, then lower the heat to a moderate boil. Cover the pot, but leave the lid slightly ajar. Cook potatoes until fork tender (should take 20-25 minutes). (Photo #4)
While the potatoes are cooking, mash the soft roasted garlic cloves into a paste. Using the back of a knife, or a fork works well. Note: The dark color of the garlic from the roasting process is completely fine and tastes wonderful! If you want to remove any dark spots for a better presentation, go for it, but it’s not necessary. (Photo #5)

Gently heat 1 stick of unsalted butter, 1 1/2 cups milk, and the mashed garlic paste in a saucepan. Break up any larger bits of garlic with a wooden spoon so that it better distributes into the butter mixture. (Photo #6)
Once the potatoes are fork-tender, drain well in a colander. While still warm, rice the potatoes into the hot pot that was used for boiling. The hot pot will help dry out any excess water still left in the potatoes. (Photo #7)

Top tips

Use a ricer. Ricing the potatoes – I like this one – eliminates the need for an electric hand mixer or the muscle to use a hand masher. An electric mixer will make the mashed potatoes starchier and almost glue-like, while the ricer will create more air gaps in the strands (rice-like strands) of potato leading to fluffier mashed potatoes.
Use the warm pot. The residual heat of the pot in which you boiled the potatoes creates the perfect environment for the riced potatoes. That heat will draw out more moisture, resulting in roasted garlic mashed potatoes that are light, and not water-logged.
Keep tasting. Taste test the potatoes a lot! Don’t be afraid to take a bite, season, mix, then take another bite. Keep doing this until you get it right. Try not to eat the entire pot of potatoes. 😉
Reheating. If preparing mashed potatoes a couple of hours before the meal (probably for Thanksgiving right?), keep them in the pot and just reheat them on low until warm. You’ll need to add a bit more butter and milk to get the right creaminess back again, but it’s as simple as that.

More Thanksgiving favorites

Roasted garlic mashed potatoes are not just for Thanksgiving.

I make these often and serve them with Stracotto, classic pot roast, meatloaf with mushroom brown gravy.

That being said, no Thanksgiving table would be complete without mashed potatoes, and a few of our other favorites:

Dry brined turkey breast – Way easier than a full wet-brained turkey, this is perfect for a smaller crowd.
Easy turkey gravy – This recipe uses cornstarch as a thickening agent making this gravy flour-free, and so easy!
Creamed spinach – with shallots and a touch of nutmeg.
Sweet potato casserole – With the best marshmallow and pecan topping.
Sausage and apple stuffed acorn squash – A meal unto itself, but definitely a favorite Thanksgiving side in our home.
Sage and onion stuffing – Country white bread stuffing full of fall flavors.
Butternut squash soup – Perfect as a light appetizer for Thanksgiving, or any Fall evening!
