Ingredients for this Fluffy Make Ahead Mashed Potatoes
Gathering things ahead makes the whole process calmer. Here’s what you’ll need:
- 2 lb russet or Yukon Gold potatoes, peeled and cut into chunks
- 1 cup whole milk
- 1/2 cup (1 stick) unsalted butter, cut into pieces
- 1/4 cup sour cream or Greek yogurt (optional)
- 1 tsp kosher salt, plus more as needed
- 1/2 tsp freshly ground black pepper
- 1 tbsp chopped fresh chives or parsley (optional garnish)
- Up to 1 cup reserved potato cooking liquid or additional milk as needed
Tip: Yukon Golds give a naturally creamy texture, while russets produce a fluffy, lighter mash. Both work — pick what you prefer.
Instructions
These steps are written like you’d talk them through with a friend. Little pauses, small checks — nothing rushed.
- Start with cold water: Put the peeled and chopped potatoes into a large pot and cover with cold water by about an inch. Add a pinch of salt. Bringing potatoes up to heat with the water helps them cook evenly.
- Boil, then simmer: Bring to a boil over high heat, then reduce to a simmer. Cook until a fork slides through easily, about 12–15 minutes depending on chunk size. If you’re watching Netflix while you cook, set a timer. Trust me.
- Warm the milk and butter: While they cook, warm the milk and butter in a small saucepan over low heat until the butter melts. Keep it warm — it blends better that way.
- Drain and dry: Drain the potatoes, reserving about a cup of the cooking liquid. Return potatoes to the pot and let them sit for a minute so excess steam escapes. This little trick keeps things from getting watery.
- Mash gently: Use a potato ricer, food mill, or masher to break them down. A ricer gives the lightest texture. Don’t overwork them — electric beaters can make potatoes gummy.
- Fold in liquids: Slowly stir in the warm milk-and-butter mixture. If you like a tang, this is the place to add the sour cream or Greek yogurt. Add reserved cooking liquid or more milk if needed to reach a fluffy consistency.
- Season and taste: Adjust salt and pepper. Taste — seasoning matters more than most people think.
- Make ahead: If you’re prepping ahead, transfer to a shallow airtight container or a buttered baking dish. Smooth the top and dot with a few small pieces of butter to help prevent a skin from forming. Refrigerate for up to 3 days.
- Reheat with care: For oven reheating, preheat to 350°F (175°C). Add a splash of milk or cream and a couple of slices of butter, cover tightly with foil, and bake 20–30 minutes until reheated through. Stir halfway through to keep it even. Stovetop reheating works too — low heat, frequent stirring, and extra milk as needed.
There you go. Simple steps, predictable results. If you’re planning a holiday, do this the day before. If it’s a weeknight dinner, you’ll be grateful you prepped ahead.

Frequently asked questions
Can I make mashed potatoes ahead and freeze them?
Yes. You can freeze mashed potatoes, but texture can change slightly. Cool completely, transfer to a freezer-safe container, and freeze for up to 2 months. Thaw overnight in the refrigerator and reheat gently with added milk or butter. For best texture, avoid overworking them during reheating.
What’s the best potato for fluffy mashed potatoes?
Russets are often the top choice for fluffy mashed potatoes because of their high starch content. Yukon Golds give a naturally creamy, slightly buttery result and are forgiving if you prefer a richer mouthfeel. If you love an airy result, go russet; want something a touch denser and buttery-tasting? Reach for Yukon Gold.
How do I prevent gummy mashed potatoes?
Three quick rules: use starchy potatoes (not waxy ones), drain and let them steam-dry briefly after cooking, and avoid overmixing. Use a ricer or mash by hand and add warm dairy slowly. If you beat them too much or add cold liquid, they can become gluey.
Final thought: Fluffy Make Ahead Mashed Potatoes are one of those dishes that reward small, thoughtful steps. A little patience — warm butter, careful mashing, a gentle reheat — and you’ll end up with light, comforting potatoes that make dinner feel like a tiny celebration. Whether it’s a holiday or just Tuesday night, having this side ready ahead is a small kindness to your future self.
Fluffy Make Ahead Mashed Potatoes
Ingredients
- 2 lb russet or Yukon Gold potatoes, peeled and cut into 1-2 inch pieces
- 1 cup whole milk
- 1/2 cup unsalted butter (1 stick), cut into pieces
- 1/4 cup sour cream or Greek yogurt (optional for tang and extra creaminess)
- 1 tsp kosher salt, plus more to taste
- 1/2 tsp freshly ground black pepper
- 1 tbsp chopped fresh chives or parsley (optional garnish)
- 1 cup reserved potato cooking liquid or additional milk as needed
Instructions
- Place the peeled and cut potatoes in a large pot and cover with cold water by 1 inch. Add a pinch of salt to the water, then bring to a boil over high heat.
- Reduce heat to a simmer and cook the potatoes until fork-tender, about 12–15 minutes depending on the size of the pieces. Test by piercing a chunk with a fork; it should slide off easily.
- While the potatoes cook, heat the milk and butter together in a small saucepan over low heat until the butter melts and the mixture is warm. Keep warm — don’t boil.
- Drain the potatoes well, reserving about 1 cup of the cooking liquid. Return the potatoes to the hot pot and let them sit for a minute to allow excess moisture to evaporate. This helps keep the mash fluffy.
- Mash the potatoes using a ricer, potato masher, or sturdy fork. For the fluffiest texture, a potato ricer or food mill works best. Avoid an electric mixer which can make potatoes gluey.
- Slowly add the warm milk-and-butter mixture to the potatoes, folding gently until incorporated. If you want extra tang, fold in the sour cream or Greek yogurt at this stage.
- If the mashed potatoes feel too stiff, add a splash of the reserved cooking liquid or extra warm milk until you reach your desired consistency. Taste and season with additional salt and pepper.
- To make ahead (refrigerator): Transfer the mashed potatoes to an airtight container or a baking dish, smoothing the top. Dot with a few small pieces of butter to help prevent a skin from forming. Cover and refrigerate for up to 3 days.
- To reheat from chilled: Preheat oven to 350°F (175°C). Place the mashed potatoes in a buttered baking dish, add a few tablespoons of milk or cream and a couple of slices of butter on top. Cover tightly with foil and bake for 20–30 minutes, stirring halfway through, until heated through and fluffy. Alternatively, reheat gently on the stovetop over low heat, stirring frequently, and adding milk as needed.
- To reheat from frozen: Thaw overnight in the fridge, then reheat by the oven method above. If reheating straight from frozen, allow extra time and check center temperature before serving.
- Just before serving, fluff the potatoes with a fork, add a pat of butter and sprinkle with chopped chives or parsley for color.
