Make these mashed potatoes up to a week ahead of time so you can concentrate on the rest of the meal. The mashed potatoes are rich with the flavors of cream cheese and sour cream.
- Spray a large dish with vegetable oil cooking spray.
- In a large pot of boiling water over medium-high heat, cook potatoes until tender when pierced with a fork; remove from heat and drain.
- Mash potatoes until there are no lumps. Add cream cheese, sour cream, onion powder, salt, pepper, and egg whites; blend well. Dot with butter or margarine. Cool slightly, cover, and refrigerate.
- Preheat oven to 350 degrees F. Take mashed potatoes out of the refrigerator 30 minutes before baking. Bake, covered, 40 minutes or until steaming hot in center. Remove from oven and serve immediately.
Note: This recipe can be made up to a week ahead. If preparing ahead, place in an ovenproof baking dish, allow to cool slightly, cover and refrigerate.
