This mashed potatoes recipe uses Yukon Gold potatoes, a gentle masher or ricer, and warm dairy to deliver creamy, fluffy potatoes that never turn gluey — ready in about 40 minutes.
1tablespoonfresh chives - finely chopped, for garnish (optional)
Instructions
Scrub, peel, and weigh the potatoes to confirm 3 pounds, then cut into even 1.5-inch chunks and place in a large pot. Cover with cold water by 1 inch and stir in 1 tablespoon kosher salt.
Bring the pot to a boil over high heat, about 8 minutes, then reduce to medium-low and simmer 12 to 15 minutes until fork-tender. Drain in a colander and shake gently to remove surface water.
While the potatoes simmer, warm the milk and cream in a small saucepan over low heat for about 3 minutes until steaming, then remove from heat and cover.
Return the drained potatoes to the empty pot over low heat and stir gently for 1 to 2 minutes until steam stops rising and a thin white film forms on the bottom. Remove from heat.
Press the potatoes through a ricer back into the pot in batches, or mash with firm downward presses until no large lumps remain. Stop as soon as the lumps are gone and never use a blender or food processor.
Add all 8 tablespoons of softened butter and fold gently with a silicone spatula until melted and glossy.
Pour in the warm milk and cream in four additions, folding gently after each until absorbed and the potatoes hold a soft peak. Season with 1 teaspoon fine sea salt and 1/4 teaspoon black pepper, tasting and adding more salt as needed.
Transfer to a warmed serving bowl, make a shallow well in the center with the back of a spoon, sprinkle with chives if using, and serve hot.
Notes
Choose Yukon Golds for a creamy, buttery mash or russets for a lighter, fluffier one; avoid waxy red potatoes, which absorb dairy poorly.
Salt the cooking water — potatoes boiled in unsalted water taste flat and cannot be fixed with salt at the end.
Steam-dry the potatoes after draining to remove surface moisture and prevent watery mash.
Always warm the dairy; cold milk and cream cool the potatoes and make the butter seize into streaks.
Use a ricer or hand masher and fold gently — blenders, food processors, and electric mixers rupture starch and turn the mash gluey.
Add dairy gradually in four additions; you can always loosen the potatoes but cannot thicken them again.
Keep potatoes hot by covering the pot with a lid and folded kitchen towel for 20 to 30 minutes, or hold a covered bowl over simmering water for up to an hour.
Store leftovers in an airtight container in the refrigerator for up to 4 days, or freeze for up to 1 month; reheat with a splash of milk and extra butter.
Variations: fold in roasted garlic, Boursin, sour cream and chives, cheddar and bacon, brown butter, or cream cheese after the dairy.
For dairy-free, replace butter with 1/3 cup olive oil and the milk and cream with 1 cup warm vegetable broth.
