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

Add a pinch of salt and bring to a boil over medium-high heat.

Cook until the potatoes are tender, about 15-20 minutes.

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

Add the melted butter, warm milk, minced garlic, salt, and pepper.

Mash the potatoes until smooth and creamy.

Transfer the mashed potatoes to a serving bowl and garnish with additional butter if desired.

Serve warm.
