Good Housekeeping published a recipe for a creamy mashed potato casserole that can be assembled and refrigerated unbaked for up to two days. The recipe serves 10 and takes about 38 to 42 minutes to bake from chilled, with butter, cream cheese, sour cream and milk in the potato mixture.
Good Housekeeping has published a mashed potato casserole recipe that can be assembled up to two days ahead and baked shortly before serving, offering a way to spread out holiday meal preparation. The recipe makes 10 servings and calls for potatoes, butter, cream cheese, sour cream, warm milk and scallions.
The recipe uses 4 pounds of gold potatoes, peeled and quartered, along with half a cup of unsalted butter, half a cup each of cream cheese and sour cream, and 1½ cups of whole milk. The potatoes are boiled until tender, then passed through a food mill or ricer, or mashed by hand. The dairy ingredients are folded in before the mixture is seasoned and combined with most of the sliced scallions.
After the potatoes are spread in a buttered 9-by-13-inch casserole dish, they can be baked right away or covered and refrigerated. For immediate serving, the recipe calls for a 425°F oven and 25 to 30 minutes of baking, until the casserole is bubbling and browned in spots. It should rest for 15 minutes before serving, with the reserved scallions scattered on top.
For the make-ahead method, Good Housekeeping says to refrigerate the unbaked, covered dish for up to two days. When ready to cook, remove it from the refrigerator and bake at 425°F for 38 to 42 minutes, or until warmed through and browned in spots. The publication lists the recipe at about 321 calories per serving; that figure is based on its stated 10-serving yield.
A Side Dish Prepared Before the Holiday
The practical value is timing: the casserole’s main preparation can be done before the day it is served, leaving only baking and resting to fit around other meal tasks. The recipe still requires a substantial oven period, but its advance instructions mean the potatoes do not need to be boiled and mixed while other dishes are being finished.
Its 10-serving yield makes it suited to a shared meal, while the rich dairy ingredients give it a different format from mashed potatoes served straight from a pot. The recipe is a planning option, not a claim that it is faster overall or more nutritious than other potato sides. Good Housekeeping describes the result as creamy; that is the publication’s characterization of the dish.

How the Two-Day Method Works
The recipe gives two paths after the potatoes are mashed and mixed: bake the casserole immediately, or cover it and refrigerate it unbaked. The stated advance window is up to two days; the source does not give instructions for freezing the dish or holding it longer.
Good Housekeeping says its culinary team tests each recipe at least three times, and often more, using different appliances and ingredient brands and gathering feedback from tasters. That is the publication’s description of its testing process; the provided report does not detail the specific testing history for this casserole.
The ingredient list includes milk, cream cheese and sour cream, so it contains dairy. The source gives approximate nutrition figures per serving, including 18.5 grams of fat, 11 grams of saturated fat and 352 milligrams of sodium. These estimates depend on the recipe’s stated yield and ingredients.
““Save yourself some time by making this creamy mashed potato casserole up to two days in advance.””
— Good Housekeeping
Details the Recipe Does Not Specify
The report does not state when the recipe was first published or provide reader ratings, independent test results or evidence comparing it with other make-ahead potato dishes. Its description of the casserole as rich and creamy is editorial language, not a measured comparison.
The instructions also do not specify whether the dish should be brought to room temperature before baking; they say to remove it from the refrigerator and bake. They provide no freezing guidance, reheating instructions for leftovers, or food-safety temperature target for the finished casserole. The stated storage limit is up to two days in the refrigerator for the covered, unbaked dish.
Bake, Rest and Serve
For cooks following the recipe, the next step depends on when the dish is assembled: bake it immediately for 25 to 30 minutes, or keep the covered casserole refrigerated for no more than two days and bake it for 38 to 42 minutes at 425°F. In either case, the recipe instructs cooks to let it rest for 15 minutes before serving and finish with the remaining scallions.
The source reports no further announcement or update tied to the recipe. Readers considering the advance method should follow the published refrigeration limit and account for the longer baking time when planning the meal.
