How to Make Overnight Mashed Potatoes

• Cut potatoes into quarters.
• Cook potatoes for about 25 minutes in boiling salted water. You will know they are done when they pierce easily with a fork.
• Drain potatoes and put them in a large mixing bowl.
• Combine potatoes with sour cream, 4 Tbsp butter, salt and pepper.
• Beat the potato mixture until light and fluffy on low speed.
• Pile into a 9x13 casserole pan. Cover and refrigerate overnight (I have made mine the same day too).
• Bake covered in a preheated 325 degree oven for an hour.
• Toss with 2 Tbsp melted butter.
• Continue baking uncovered about 30 minutes longer.
