Place the potatoes into a large pot, cover with cold water, and add a generous pinch of salt. Bring to a boil over medium-high heat and cook for 15-20 minutes, or until the potatoes are fork-tender.

While the potatoes cook, melt the butter in a small saucepan over medium heat. Add the minced garlic and cook for 1-2 minutes until fragrant, but not browned.

Drain the potatoes and return them to the pot. Mash using a potato masher or hand mixer until smooth.

Serve hot with a drizzle of melted butter or extra parmesan cheese.
