1. Place the cubed potatoes in a large pot and fill it with cold water until fully submerged. Add a pinch of salt to season the water.
2. Bring the water to a boil over medium-high heat, then lower the heat to a gentle simmer. Cook until the large chunks are fork tender, this can take about 20-25 minutes.
3. While the potatoes cook, melt the butter in a small saucepan over medium heat. Add the minced garlic and cook until it becomes aromatic. Be careful not to let the garlic brown. Remove from the heat and set aside.
4. Once the potatoes are done, drain excess water and return them to the pot. Let them sit for a minute or two to allow any remaining steam to escape.
5. Use a potato masher or ricer to mash the potatoes until they reach a smooth consistency. Pour in the garlic butter, heavy cream, sour cream, salt, and black pepper. Stir well, adding more cream as needed to achieve your preferred texture. Mix until the potatoes are soft, creamy, and thoroughly combined.
6. Spoon the mashed potatoes into a serving dish and top with an extra pat of butter for richness. Sprinkle with paprika or garnish with freshly chopped parsley or chives for a pop of color and flavor. Enjoy!
