Peel and cut the potatoes into even 1.5-inch chunks, then rinse any excess starch.

Place the potato chunks in a pot with cold water and a pinch of salt. Bring to a boil, then reduce to medium heat and cook for 15-20 minutes until fork-tender.

Drain the cooked potatoes in a colander and let them sit for a minute to remove excess moisture.

Return the drained potatoes to the pot over low heat and mash until smooth and fluffy, avoiding over-mixing.

Melt the butter and heat the milk in a small saucepan. Gradually mix them into the mashed potatoes, seasoning with salt and pepper.

Serve the mashed potatoes immediately while warm, pairing them with your favorite main dishes.
