Butter Mashed Potatoes — The Creamiest Seed Oil Free Recipe
By Savannah Ryan — The Foodie Kitchen
Quick answer: The creamiest mashed potatoes come from Yukon Gold potatoes, generous grass-fed butter added off the heat and warm cream — never cold — pressed through a ricer rather than beaten, which avoids the gluey texture that over-worked mash produces.
Mashed potatoes are one of the most searched recipes on the internet every single month — and almost every mainstream version calls for butter plus a splash of milk or cream, which means they are already seed oil free by default. The version most people make just needs one improvement: more butter, better butter and the right technique. This is the definitive butter mashed potato recipe — Yukon Golds for their natural creaminess, grass-fed butter for its flavour and fat-soluble vitamins, and warm cream that absorbs rather than cools the mash. No canola oil. No margarine. No seed oils of any kind.
Butter Mashed Potatoes — The Recipe
Ingredients
- 1.2kg Yukon Gold potatoes — peeled and cut into even chunks
- 120g grass-fed butter — cold, cut into cubes
- 150ml full fat cream — warmed
- 1 teaspoon fine salt plus more to taste
- Half teaspoon white pepper
- Optional: 2 cloves roasted garlic, chives to finish
Method
Place the potato chunks in a large pot of cold salted water. Bring to the boil and cook for 18 to 20 minutes until completely tender — a knife should slide in with zero resistance. Do not undercook. Undercooked potatoes cause lumpy mash that no amount of butter will fix.
Drain thoroughly. Return the pot to low heat for 1 minute with the drained potatoes inside, shaking the pot — this drives off excess steam and moisture, which is what causes watery mash.
Pass the potatoes through a ricer or fine sieve directly back into the warm pot. Never use a food processor or stand mixer — over-beating breaks down the potato cell walls and releases excess starch, producing gluey rather than fluffy mash.
Add the cold butter cubes all at once. Stir gently with a wooden spoon — the cold butter melts slowly and emulsifies into the hot potato, creating the creamy texture rather than greasy pools of fat.
Add the warm cream in two additions, stirring gently between each. Warm cream incorporates without cooling the mash or causing it to tighten. Season with salt and white pepper. Taste and adjust.
Serve immediately — mash does not hold. If you need to hold it briefly, press clingfilm directly onto the surface to prevent a skin forming and set the pot over a bain marie on very low heat.
Chef's tip
The butter must be cold when it goes into the hot potato. This sounds counterintuitive but cold butter melts gradually and emulsifies into the starch — producing a creamy, cohesive texture. Warm or melted butter added to hot potato separates into greasy pools. Same principle as making a beurre blanc.

Frequently Asked Questions
Why are my mashed potatoes gluey?
Gluey mash is caused by over-working the potato after cooking, which breaks cell walls and releases excess starch. Use a ricer or sieve rather than a mixer, and stop stirring as soon as the butter and cream are incorporated.
What potatoes are best for mashed potatoes?
Yukon Gold potatoes produce the creamiest mash because their natural butter flavour and waxy-starchy balance means they require less added fat to taste rich. Russets produce fluffier mash. Avoid waxy varieties like red potatoes — they produce dense, sticky mash.
Is butter healthier than margarine for mashed potatoes?
Yes significantly. Grass-fed butter contains fat-soluble vitamins A, D, E and K2, conjugated linoleic acid and a fat profile that is stable at cooking temperatures. Margarine is hydrogenated seed oil — it contains trans fats in many formulations and none of the fat-soluble nutrients present in butter.
Can I make mashed potatoes without cream?
Yes. Replace the cream with warmed full fat milk, warm chicken or vegetable bone broth, or simply more butter. The key is that any liquid added must be warm — cold liquid cools the mash and causes the butter to seize rather than emulsify.
How do I keep mashed potatoes warm?
Press clingfilm directly onto the surface of the mash and set the pot over a bain marie — a larger pot of barely simmering water — on very low heat. This holds mash at serving temperature for up to 30 minutes without skin forming or the texture deteriorating.
