3large russet potatoesbaked and cooled overnight in the fridge
3tablespoonssalted butter
¼cupdiced shallot
1clovegarlicminced
2teaspoonssalt
½teaspoonground black pepper
1 ½cupssour cream
2 ½cupsfreshly shredded sharp white cheddar cheesedivided
½cupgrated parmesan
Instructions
Preheat oven to 375℉ and grease a 2 qt baking dish.
In a small pan, melt the butter over medium low heat and saute the shallot until softened and translucent, about 4 minutes. Add the garlic and cook for 30 more seconds. Remove from heat.
Using a box grater or food processor, grate the cooled baked potatoes with the skin still on.
In a large mixing bowl stir together the sour cream, salt, pepper, 2 cups of the cheddar, and the sauteed shallot and garlic. Gently fold in the shredded potatoes until just evenly combined, trying to keep the shredded texture.
Lightly pile the potato mixture into the prepared casserole dish and evenly top with the remaining cheddar and parmesan cheese. Bake for 25-30 minutes until golden brown.
Notes
The recipe states that this will make 6 servings, but at a holiday buffet where there are lots of sides, you could easily get 8-10 servings.
Store leftovers in a covered container in the fridge for up to 5-6 days.
To reheat, cover the leftovers with foil and reheat in a 350℉ oven until warmed.
If your potatoes are dry when you reheat them, you can add a splash of milk or cream. I also like to add a little fresh shredded cheese on top before baking.
Make a day in advance and just store in the fridge until ready to bake. Increase bake time to 45 minutes. If the top starts getting too brown, cover with foil.
