3 pounds russet potatoes (about 6; peeled if desired), cut into 2-inch chunks 3 ounces bacon (6 slices) 3/4 cup whole milk 8 tablespoons (1 stick) unsalted butter, cut up 4 ounces blue cheese, crumbled

1. Place the potatoes in a large pot and add 2 teaspoons salt and enough cold water to cover. Bring to a boil. Reduce heat and simmer until the potatoes are very tender, 20 to 25 minutes. Drain and return the potatoes to the pot.
2. Meanwhile, in a large skillet, cook the bacon over medium heat until crisp, 5 to 8 minutes. Transfer to a paper towel-lined plate. Let cool, then crumble.
3. Add the milk, butter, ½ teaspoon salt, and ¼ teaspoon pepper to the potatoes and mash to the desired consistency. Fold in the bacon and top with the blue cheese.
