Creamy Mashed Potatoes
Preheat the oven to 350 degrees F. Generously butter a 4-quart baking dish.
Drain the potatoes in a large colander. Place them back into the dry pot and put the pot on the stove. Mash the potatoes over low heat, allowing all the steam to escape before adding in all the other ingredients.
Spread the potatoes in the prepared baking dish. Throw pats of the remaining butter over the top of the potatoes and bake until the butter is melted and the potatoes are warmed through, 20 to 30 minutes.
