Step 1

Clean and chop your potatoes into 1-inch chunks. If you like your mashed potatoes skinless, you can peel your potatoes beforehand but I find yellow flesh potatoes have a pretty thin skin, so I don’t bother to do that. Place the potatoes and the garlic cloves in a large stockpot and fill with water, so it covers the potatoes by 1-inch. Add 3 teaspoons of salt to the water and bring to a boil. Once boiling, lower heat to let the water simmer, and cook potatoes for 10 to 15 minutes, or until a fork pierces the potatoes easily.

Step 2

While the potatoes cook, clean the leek by slicing it lengthwise and fanning them out under running water to remove the dirt and sand. Chop the white part and 1-inch of the green part of the leek. Add them to a pan with the butter and turn the heat to medium high. Cook the leeks until they soften and start to a look a little translucent, about 3 to 5 minutes. Remove from heat.

Step 3

Once the potatoes are done, drain them in a colander, then place them back into the hot pan they cooked in.

Step 4

Add the leeks (with all the melted butter), sour cream, heavy cream along with the remaining 1 teaspoon salt and pepper. Mash the potatoes with a potato masher and add more cream, salt and pepper to your own taste.

Step 5

Scoop into a large serving bowl, drizzle with the melted butter and garnish with chopped parsley.
