Close your eyes and think of the most perfect mashed potatoes you’ve ever tasted. They were probably not from a restaurant, but from a family table—specifically, your grandmother’s. They were impossibly light yet rich, buttery without being greasy, and so smooth they practically melted on your tongue.

Gathering Your Ingredients (Serves 6-8)
The Potatoes & Basics:
- 3 lbs Russet or Yukon Gold potatoes

Optional Garnish:
- 2 tablespoons fresh chives or parsley, finely chopped
- A pat of butter for the top
The Foolproof, Step-by-Step “Grandma” Method
Step 1: Prep the Potatoes the Right Way
- Peel the potatoes and cut them into uniform 1.5-inch chunks. The similar size is crucial for even cooking.
- Place the chunks in a large pot and cover them with cold water by at least an inch. Add the tablespoon of kosher salt.
Step 2: Cook to Perfect Tenderness
- Bring the water to a boil over high heat, then reduce to a gentle simmer.
- Cook for 15-20 minutes, or until the potatoes are fork-tender. You should be able to easily pierce a chunk with a fork with no resistance.
- Do not overcook until they are falling apart, or they will become waterlogged.
Step 3: The Crucial Draining & Drying Step
- Drain the potatoes immediately in a large colander.
- Here is Grandma’s #1 Secret: Return the empty, hot pot to the warm (but turned off) stove. Add the drained potatoes back into the pot and let them sit for 1-2 minutes, gently shaking the pot occasionally. This allows the residual heat to steam off any excess moisture. Wet potatoes make watery mashed potatoes!
Step 4: Rice or Mash for the Perfect Texture
- While the potatoes are still hot, press them through a potato ricer back into the pot. This is the absolute best way to achieve a light, lump-free texture.
- No Ricer? Use a standard potato masher. Mash until smooth, but don’t overwork them, or they can become gluey.
Step 5: Bring in the Goodness
- Add the softened butter and the sour cream to the hot, riced potatoes. Stir gently with a wooden spoon or spatula until the butter is melted and incorporated.
- Gradually pour in the warm milk, stirring constantly, until you reach your desired creamy consistency. You may not need all the milk.
- Season to taste with salt and a pinch of white pepper (which won’t leave black specks).
Step 6: Serve with Love
- Transfer the mashed potatoes to a warm serving bowl.
- Make a well in the center with the back of a spoon and place a final pat of butter in it, letting it melt gloriously down the sides.
- Sprinkle with fresh chives or parsley and serve immediately.
5 of Grandma’s Pro-Tips for Perfection
- Start in Cold Water: Always place potatoes in cold, salted water before bringing to a boil. This ensures they cook evenly from the outside in.
- Warm Your Dairy: Never add cold milk or butter to hot potatoes. It brings down the temperature and makes them gummy. Warm the milk and soften the butter first.
- The Sour Cream Secret: Sour cream is the magic ingredient. It adds a subtle tang that cuts the richness and makes the potatoes incredibly creamy and stable.
- Don’t Use a Blender or Food Processor: This is the fastest way to create a glue-like, sticky disaster. A ricer or hand masher is the only way to go.
- Keep Them Warm: If you need to hold them before serving, place them in a heatproof bowl over a pot of simmering water (a double boiler) and cover with a lid.
Frequently Asked Questions (FAQ)
Q: Can I make these ahead of time?
A: Yes! Prepare the potatoes completely, transfer to a buttered baking dish, dot with butter, and cover. Refrigerate for up to 2 days. Reheat, covered, in a 350°F (175°C) oven for 30-40 minutes until hot. Stir before serving.
Q: Why are my mashed potatoes gummy?
A: This is almost always caused by overmixing. Too much agitation breaks down the starch cells, releasing too much starch. Be gentle when combining!
Q: What’s the best potato to use?
A: Russets are the classic choice for the fluffiest texture. Yukon Golds are a great alternative—they are naturally buttery and creamier, so they mash up beautifully with a slightly richer flavor.
Q: My potatoes are too thin/runny. How can I fix them?
A: You can cook a few additional potato chunks, rice them, and stir them into the runny batch to thicken them up.
