Place the peeled and cut potatoes in a large pot and cover with cold water.

Add salt to the water and bring to a boil over high heat.

Once boiling, reduce heat to medium and cook until potatoes are tender, about 15-20 minutes.

Drain the potatoes in a colander and return them to the pot.

Add melted butter and warmed milk to the potatoes.

Mash the potatoes using a potato masher until smooth and creamy.

Season with salt and pepper to taste, mixing well.

Transfer the mashed potatoes to a serving bowl and serve warm.
