Notes

Heat the butter and milk in the same saucepan you’ll use for mashing so they’re steaming when they hit the potatoes—hot dairy soaks in quickly and prevents gumminess. For a subtle upgrade, steep a bay leaf or cracked peppercorns in that warm mixture for 5 minutes, then strain before blending for a layered, savory finish.

Frequently Asked Questions

Can I prepare these mashed potatoes in advance and reheat them later without sacrificing their creamy texture?
Yes—mashed potatoes hold up well when made up to two days ahead. Cool them quickly, cover, and refrigerate; when ready to serve, reheat gently over low heat or in the microwave, stirring in a splash of warm milk or melted butter to revive their silky texture.
Q2: How can I keep my mashed potatoes from turning gluey or gummy during preparation?
Use high-starch potatoes (such as Russets), drain well, and mash them while still hot with a ricer or hand masher—never a food processor—which keeps starch granules intact. Stream in butter and milk that are already steaming so they absorb quickly, requiring minimal stirring. The combination of hot dairy and gentle handling prevents over-working the potatoes, which is what turns them gluey.
Can I make these mashed potatoes dairy-free or vegan?
Yes. Substitute the butter with olive oil or vegan butter and use warmed, unsweetened almond, soy, or oat milk in place of dairy; finish with a splash of the same plant milk or a drizzle of olive oil for extra silkiness. All other steps stay the same, giving you creamy, fully dairy-free/vegan mashed potatoes.
