How to Make It
Heat oven to 400° F. Fill a large pot with the potatoes and 1 inch of water. Bring to a simmer, cover, and steam until very tender, 18 to 22 minutes. Strain and return the potatoes to the pot.
Add the milk, cream cheese, butter, 2 teaspoons salt, and ½ teaspoon pepper to the potatoes and mash until smooth. Fold in the eggs; transfer to a buttered 8-by-8-inch or other 2-quart baking dish. Bake until set and golden, 25 to 30 minutes (or 40 minutes if refrigerated before baking).
