Make-ahead Mashed Potatoes
How to Make Make-ahead Mashed Potatoes
- 1Preheat the oven to 325 degrees F (165 degrees C).
- 2Place potatoes in a large pot of lightly salted water. Bring to a boil, and cook until tender, about 15 minutes. Drain, and mash.
- 3In a large bowl, mix mashed potatoes, cream cheese, sour cream, milk, onion salt, and pepper. Transfer to a large casserole dish. Cut up the stick of butter and add "chunks" across the top of the potatoes. The butter will melt while cooking, giving the potatoes an extra buttery flavor.
- 4Cover, and bake for 50 minutes in the preheated oven.
