Good Housekeeping published a mashed potato casserole recipe that serves 10 and can be prepared up to two days before it is baked. The recipe uses gold potatoes, butter, cream cheese, sour cream, warm milk and scallions; its make-ahead baking time is 38 to 42 minutes at 425°F.
Good Housekeeping has published a make-ahead mashed potato casserole recipe that can be assembled and refrigerated for up to two days before baking. The recipe makes 10 servings and gives holiday cooks a way to prepare the side dish in advance, with a longer oven time for the chilled casserole.
The recipe calls for 4 pounds of medium gold potatoes, peeled and quartered, along with unsalted butter, cream cheese, sour cream, warmed whole milk, salt and sliced scallions. The potatoes are boiled until just tender, then mashed or passed through a food mill or ricer. The dairy and butter are folded in before most of the scallions are added.
For advance preparation, the unbaked casserole is spread in a buttered 9-by-13-inch dish, covered and refrigerated for up to two days. When it is time to serve, the recipe directs cooks to heat the oven to 425°F and bake the casserole for 38 to 42 minutes, until heated through and browned in spots. The dish is left to stand for 15 minutes and finished with the reserved scallions.
If baked immediately after assembly, the casserole takes 25 to 30 minutes in the oven, according to the recipe. Good Housekeeping lists the total preparation and cooking time as 1 hour 40 minutes and estimates 321 calories per serving. Those figures are the publication’s recipe information, not an independently verified nutrition analysis.
A Side Dish Prepared Ahead
The recipe’s practical point is its two-day refrigerator window: cooks can complete the boiling, mashing and mixing before a busy meal, then bake the casserole closer to serving time. That can move some kitchen work away from the day of a holiday gathering, when oven and preparation schedules may be crowded.
The advance option does not remove the need to plan for oven time. The chilled dish is directed to bake for 38 to 42 minutes, compared with 25 to 30 minutes when baked without refrigeration. Readers should account for that difference when coordinating a meal; the source does not provide guidance on adapting the recipe for a different dish size or oven temperature.

How the Recipe Is Made
The recipe is a baked version of mashed potatoes, combining the mashed potatoes with butter, cream cheese and sour cream before adding warmed milk. The method calls for 2 teaspoons of salt in the boiling water and another teaspoon in the potato mixture, with the scallions divided between the mixture and the topping.
Good Housekeeping says its culinary team tests each recipe at least three times and may test it more often, using different appliances and ingredient brands and gathering feedback from tasters. That is the publication’s stated testing process; the supplied report does not provide details about the specific testing rounds for this casserole.
“Save yourself some time by making this creamy mashed potato casserole up to two days in advance.”

Details the Recipe Does Not Give
The supplied source does not state the article’s publication date, identify a holiday or event for which the recipe was developed, or report reader testing of this particular casserole. It also does not explain whether the dish can be frozen, how long leftovers keep, or how to adjust the baking time for a different quantity or pan.
The nutrition figures are presented as approximate per-serving estimates, and the source does not give a detailed calculation method. The recipe states a yield of 10 servings, but serving sizes may vary depending on how the casserole is divided.
Bake Before Serving
For cooks following the make-ahead method, the next steps are to cover the assembled casserole, refrigerate it for no more than two days, and bake it at 425°F until hot throughout and browned in spots. The source gives a 38-to-42-minute range and recommends a 15-minute rest before serving, but does not specify a separate internal-temperature target.
The publication invites readers who make the recipe to leave a comment. No reader feedback or subsequent update is included in the supplied report, so there is no additional reaction to report here.
