Best Mashed Potatoes

In a large pot, cover potatoes with water and add a generous pinch of salt. Bring to a boil and cook until softened, 15 to 20 minutes.

Drain and return potatoes to pot. Using a potato masher or ricer, mash potatoes until smooth.

While potatoes cook, in a small saucepan over medium-low heat, cook milk and 3/4 c. butter, stirring occasionally, until butter is melted and mixture is warmed through, about 3 minutes.

Pour milk mixture over potatoes and stir until combined and creamy. Add sour cream and stir until combined; generously season with salt and pepper.

Transfer potatoes to a serving bowl. Top with remaining 2 Tbsp. butter; season with more pepper. Top with parsley.
