The Perfect Mashed Potatoes Recipe (Serves 4–6)
Here is the full method so you can try it yourself tonight.
Ingredients
- 1 kg (2 lbs) Yukon Gold or Russet potatoes, peeled and cut into even chunks
- 6 tablespoons (85g) unsalted butter, cut into cubes
- 1 tablespoon salt for the cooking water
- Salt and freshly ground black pepper to taste
- Optional: 2–3 garlic cloves, fresh rosemary or thyme, a drizzle of good olive oil
Step 1: Cook the Potatoes
Place the potato chunks in a large pot and cover with cold water — starting in cold water rather than boiling ensures they cook evenly all the way through. Add a generous tablespoon of salt and bring to a boil. Cook for 15 to 20 minutes until a fork slides through without any resistance.
Step 2: Save the Water
Before you drain the potatoes, ladle out about 1 full cup of the cooking water and set it aside. This step is the most important part of the whole recipe — do not skip it. Once you have saved the starchy water, drain the potatoes and return them to the hot pot. Let them sit over low heat for 1 to 2 minutes, shaking occasionally, to steam off any excess moisture. Dry potatoes absorb flavor better and mash to a fluffier texture.
Step 3: Build the Butter Emulsion
Add the cold butter cubes directly to the reserved potato water while it is still hot and whisk vigorously until the butter melts completely and the mixture becomes smooth, glossy, and emulsified. It should look slightly creamy and have a beautiful sheen. This is your magic liquid — the key to restaurant-quality mash.
Step 4: Mash and Combine
Mash the potatoes using a potato masher or ricer until they are broken down. Then gradually pour in your butter-water emulsion, stirring and folding as you go. Add it slowly — you may not need the entire cup. Stop when the texture is exactly how you like it: smooth, creamy, and just loose enough to fall gently from a spoon. Season generously with salt and pepper.
