Instructions
- Step 1: Place 1.5 lbs Yukon Gold potatoes (peeled and cut into 1-inch cubes) in a large pot and cover with cold water. Bring to a boil over high heat, then reduce to a simmer and cook for 15-20 minutes until fork-tender.
- Step 2: Melt 1 tbsp butter in a small skillet over medium heat. Add 2 medium leeks (white and light green parts only, thinly sliced) and cook for 5-7 minutes until softened and golden, stirring occasionally.
- Step 3: Drain the potatoes and return to the pot. Add 2 tbsp butter (from step 2), 1/4 cup milk, and 1/4 cup heavy cream. Mash until smooth, then stir in the cooked leeks and 2 tbsp of the chopped chives. Season with salt and pepper to taste.
- Step 4: Transfer to a baking dish and spread evenly. Mix the remaining 2 tbsp chives with 1 tbsp butter and dot over the top. Bake at 375°F for 15 minutes until golden and crispy.
