A bowl of mashed potatoes should be the easy part of a holiday meal. Here, a whole head of roasted garlic gives mellow flavor, cream cheese adds body, and warm milk helps the potatoes stay creamy without aggressive mixing. The recipe serves eight and can be made a day ahead, freeing the stovetop when the rest of dinner needs attention.

At a glance: Prep 20 minutes; cook about 50 minutes; total about 1 hour 10 minutes for immediate serving. The potatoes simmer while the garlic roasts. Optional next-day reheating adds 30 to 40 minutes and is separate from this fresh-cook time.
Why these mashed potatoes work
Roasting turns sharp raw garlic into a soft paste that disperses through the mash. Yukon Gold potatoes offer a naturally buttery texture, while cream cheese gives the make-ahead version enough structure to reheat without becoming runny. Draining and briefly drying the cooked pieces prevents excess water from diluting the warm dairy.
Ingredients
Ingredients at a glance
- 3 pounds Yukon Gold potatoes, peeled and cut into 1 1/2-inch pieces
- 1 whole head garlic
- 1 teaspoon olive oil
- 4 tablespoons unsalted butter, divided (3 tablespoons for the mash and 1 tablespoon for serving)
- 3/4 cup whole milk
- 4 ounces plain cream cheese, softened
- 1 1/2 teaspoons kosher salt, divided, plus salt for the cooking water
- 1/2 teaspoon freshly ground black pepper
- 2 tablespoons finely chopped fresh chives, optional for serving
Ingredient notes: Peel the potatoes for the smooth, skin-free texture shown in the photos. Use a plain brick of cream cheese, not a flavored spread. The tablespoon of butter reserved for the top is included in the four tablespoons listed above. Chives are optional, but add a fresh color contrast.
Equipment and timing
Have a large pot, colander, small oven-safe dish, foil, small saucepan, and hand masher or potato ricer ready. Peel and cut the potatoes during the 20-minute preparation window. Start the garlic and the pot together so the 15-to-20-minute simmer happens within the roughly 40-minute garlic roast. Finish by drying, warming the dairy, mashing, and serving.
Step-by-step instructions
Step 1: Roast the garlic
Heat the oven to 375°F (190°C). Slice about 1/4 inch from the top of the garlic head to expose the cloves. Set it cut-side up in a small oven-safe dish, drizzle with the olive oil, and cover tightly with foil. Roast for about 40 minutes, until the cloves are soft and golden. Set aside until cool enough to handle.
Step 2: Simmer the potatoes
As soon as the garlic goes into the oven, put the prepared potato pieces in a large pot and cover with cold water by 1 inch. Salt the water, bring it to a boil, then lower to a steady simmer. Cook for 15 to 20 minutes, until a fork slides into the thickest piece without resistance. Starting the pot while the garlic roasts lets the two cooking tasks overlap.
Step 3: Drain and dry the potatoes
Drain the potatoes thoroughly in a colander. Return them to the still-warm, empty pot over low heat for 1 to 2 minutes, shaking the pot gently so surface moisture evaporates. Turn off the heat. Drying the pieces now keeps the final mash from becoming watery.
Step 4: Warm the dairy and squeeze the garlic
Warm the milk with 3 tablespoons of the butter in a small saucepan over low heat for about 2 minutes, just until the butter melts; do not boil. Squeeze the soft roasted garlic cloves from their skins into a small bowl and mash them with a fork. Keep the remaining 1 tablespoon butter for serving.
Step 5: Mash and fold everything together
Mash the hot potatoes with a hand masher or pass them through a ricer. Add the roasted garlic, softened cream cheese, 1 teaspoon of the kosher salt, and the pepper. Pour in the warm milk mixture a little at a time, folding gently until creamy. Taste and add up to the remaining 1/2 teaspoon salt if needed. Stop mixing as soon as smooth enough; vigorous beating can make the potatoes gluey.
Step 6: Finish and serve
Spoon the potatoes into a warm serving bowl. Add the reserved tablespoon of butter and scatter the chives over the top, if using. Serve while hot. For a make-ahead meal, transfer the mash to a shallow baking dish before adding the final butter and chives, then follow the reheating directions below.
Make-ahead tips
Complete the mash through step 5 up to one day ahead. Spread it in a shallow baking dish, cool it promptly, cover, and refrigerate at 40°F (4°C) or below within two hours of cooking. Hold the reserved butter and chives for serving. A shallow layer reheats more evenly than a deep pot of cold potatoes.
Reheat the make-ahead dish
Heat the oven to 350°F (175°C). Cover the chilled dish with foil and bake for about 30 to 40 minutes, stirring once halfway through. Check the center with a food thermometer; it must reach 165°F (74°C). If the mash seems firm, fold in 1 to 2 tablespoons of warm milk after heating. Transfer to a serving bowl or serve from the dish with the reserved butter and optional chives. Check your baking dish manufacturer’s guidance before moving chilled ceramic directly into a hot oven.
Storage and leftovers
Refrigerate leftovers in shallow, covered containers within two hours. Keep at 40°F (4°C) or below and use within 3 to 4 days. Reheat only the portion you need until it reaches 165°F (74°C), adding a splash of warm milk if necessary. Freeze in airtight portions for up to one month for best texture; thaw in the refrigerator before reheating. The texture may be less fluffy after freezing.
Troubleshooting
- Watery: Return the drained potatoes to the warm pot briefly before mashing and add the milk in stages.
- Gluey: Use a hand masher or ricer and stop as soon as the dairy is incorporated; avoid a blender or food processor.
- Too firm after refrigeration: Stir in warm milk a tablespoon at a time after reheating rather than pouring in a large amount before baking.
- Garlic tastes sharp: Roast until the cloves are fully soft and golden, not merely warmed through.
What to serve alongside
Pair these potatoes with green bean casserole with fresh beans for a holiday side-dish spread. A tangy cranberry sauce adds contrast to the rich mash.
Frequently asked questions
Can I roast the garlic a day early?
Yes. Refrigerate the cooked garlic promptly in a covered container and use it within the same one-day make-ahead window. Squeeze the cloves into the potatoes when you mash.
Can I use russet potatoes?
Yes, but they turn fluffy rather than naturally creamy and can become pasty with too much mixing. Use the same weight, peel them, and add the warm milk gradually.
Do I need a potato ricer?
No. A hand masher works well if you keep the strokes gentle and stop once the potatoes are creamy. A ricer gives a finer texture but is optional.
