Roasted Garlic Mashed Potatoes

This roasted garlic mashed potato recipe transforms the humble spud into a creamy, aromatic side dish that will steal the spotlight at any dinner table. The slow-roasted garlic adds a mellow, nutty sweetness that elevates these potatoes beyond the ordinary, creating something truly memorable that your guests will rave about.

I first made these mashed potatoes for a Thanksgiving dinner when I was terrified of hosting my in-laws. The garlic aroma filled the house and immediately broke the ice everyone was oohing and aahing before the dish even hit the table.

Ingredients

• Whole garlic head: the star of the show that transforms from pungent to sweet when roasted
• Red potatoes: their waxy texture and thin skins create the perfect creamy yet slightly chunky consistency
• Olive oil: helps the garlic roast to golden perfection
• Kosher salt: enhances all the flavors without tasting overly salty
• Butter: creates richness and silky texture
• Half and half: the perfect balance between milk and cream for luxurious potatoes
• Fresh ground pepper: adds a subtle heat that balances the sweetness of the roasted garlic

Step-by-Step Instructions

Roast the Garlic:

Cut off the top quarter inch of a whole garlic head to expose the cloves inside. Place the garlic on a piece of foil and drizzle with olive oil, making sure it seeps between the cloves. Wrap the foil tightly around the garlic and place in a 375°F oven for about an hour. The kitchen will fill with an incredible aroma as the garlic transforms from sharp and pungent to mellow and sweet. The cloves should be golden brown and so soft you can squeeze them out of their papery skins with gentle pressure.

Boil the Potatoes:

Place quartered red potatoes in a large pot and cover with cold water – never hot which can lead to uneven cooking. Add a generous teaspoon of kosher salt to the water – this seasons the potatoes from the inside out. Bring to a boil, then reduce to a simmer for about 15 minutes. Test for doneness by inserting a fork – the potatoes should yield easily but not fall apart completely.

Prepare for Mashing:

Drain the potatoes thoroughly in a colander, then return them to the still warm pot. The residual heat will help evaporate excess moisture, preventing soggy potatoes. Squeeze the roasted garlic cloves directly into the pot with the potatoes – they should slide right out of their skins.

Create Creamy Texture:

Warm the half and half and butter together until the butter melts completely. This crucial step ensures your potatoes stay hot and the dairy incorporates smoothly. Pour this mixture over the potatoes and garlic, season with salt and pepper, then mash with a potato masher. Work quickly but gently, mashing just until you achieve a creamy texture with some small lumps for character. Overmashing can make potatoes gluey.

The first time I served these potatoes to my childhood friend who claimed to hate garlic, she asked for seconds and then demanded the recipe. That moment taught me that properly cooked garlic can convert even the strongest skeptics. Now I make a double batch of roasted garlic just to have extra for spreading on bread or adding to other dishes.

Make Ahead Magic

These mashed potatoes reheat beautifully, making them perfect for busy holiday meals. Prepare them up to two days in advance, store in an airtight container in the refrigerator, then reheat in a covered baking dish at 350°F for about 30 minutes. Add a splash of cream and dot with butter before reheating to refresh the texture. The flavors actually develop and improve with time, making this one of those rare dishes that tastes even better the next day.

Variations To Try

Change up these potatoes based on what you have on hand. Yellow Yukon Gold potatoes create an even more buttery result. For a dairy free version, substitute olive oil for butter and use unsweetened almond milk in place of half and half. You can add other roasted vegetables like parsnips or cauliflower to the potatoes before mashing for additional flavor dimensions. Fresh herbs like chives, rosemary, or thyme make wonderful additions stirred in just before serving.

Perfect Pairings

These garlic mashed potatoes complement virtually any protein. They shine alongside a holiday turkey or ham, but are equally delicious with a simple roasted chicken or grilled steak. For vegetarians, serve with roasted vegetables and a rich mushroom gravy. The subtle sweetness of the roasted garlic pairs particularly well with slightly bitter greens like Brussels sprouts or kale. For a complete comfort food experience, serve alongside meatloaf with a side of green beans.
