Ingredients

Original recipe (1X) yields 12 servings

  • 5 pounds potatoes, peeled and cut into chunks

  • 1 (8 ounce) container sour cream

  • 1 (8 ounce) package cream cheese, softened

  • ¼ cup margarine

  • 1 tablespoon milk

  • 1 tablespoon garlic powder, or more to taste

  • 2 ½ teaspoons salt

  • ¼ teaspoon ground black pepper

  • ½ cup shredded Colby-Jack cheese, or more to taste

Directions

  1. Place potatoes into a large pot and cover with salted water; bring to a boil. Reduce heat to medium-low and simmer until tender, 15 to 20 minutes. Drain.

  2. Return potatoes to the pot and mash until smooth. Add sour cream, cream cheese, margarine, and milk; beat until light and fluffy. Add in garlic powder, salt, and pepper. Transfer to a 9x13-inch casserole dish.

  3. Bake in the preheated oven until heated through, 30 to 40 minutes. Sprinkle Colby-Jack cheese over top and bake until cheese is melted, about 5 more minutes.

Cook's Note:

Also tastes great to with light sour cream and reduced-fat cream cheese.
