These are my make ahead Thanksgiving potatoes. They are definitely not diet, hence I only make them at holidays or when my daughters come into town! They are good. Baking the potatoes is worth it.....boiling them can make them starchy and gummy...there is no chance of this when using baked.

Swapping russet potatoes for waxy red varieties changes the final starch structure entirely. Russets yield a fluffy interior because their dry, high-starch cells break apart easily under a masher. Waxy potatoes contain less starch and more moisture, resulting in a dense, gluey mash when combined with heavy dairy fats. Baking tubers whole rather than boiling them prevents waterlogging. Submerging potatoes in boiling water saturates the flesh, while dry-heat baking allows internal moisture to evaporate, creating ideal conditions for absorbing melted butter and sour cream.
Assembled casseroles hold safely in the refrigerator for up to 24 hours before baking. Chilling allows the cubed cheddar cheese to firm up and the roasted garlic aromatics to permeate the potato pulp. To reheat properly, temper the casserole on the counter for 30 minutes to take the chill off the center. Cover the dish tightly with aluminum foil to retain moisture during the initial 20 minutes at 350 degrees Fahrenheit. Remove the foil for the final 10 minutes to develop a lightly browned surface.
