With five different dairy products, you know this make-ahead mashed potato casserole is going to be super rich and, of course, delicious. It gets even better topped with onions and bacon! —JoAnn Koerkenmeier, Damiansville, Illinois


  • 3 pounds potatoes (about 9 medium), peeled and cubed
  • 8 ounces cream cheese, softened
  • 1/2 cup sour cream
  • 1/2 cup butter, cubed

  • 1-1/2 teaspoons onion powder
  • 1 teaspoon salt
  • 1 teaspoon garlic powder
  • 1/2 teaspoon pepper
  • Optional: Shredded cheddar cheese, crumbled cooked bacon and chopped green onions


  1. Place potatoes in a Dutch oven; cover with water. Bring to a boil. Reduce heat; cook, uncovered, 10-15 minutes or until tender. Drain potatoes; return to pan.
  2. Mash potatoes, gradually adding cream cheese, sour cream and butter. Stir in milk and seasonings. Transfer to a greased 13x9-in. baking dish. If desired, sprinkle with cheese and bacon. Refrigerate, covered, up to 1-2 days.
