Recipe Notes

  • You could use russet potatoes for this casserole recipe, but Yukon gold potatoes do have a special buttery flavor that adds a lot to the dish. 
  • The recipe calls for peeling the potatoes, but if you like the peel, leave it on. 
  • You could use other cheeses instead of cheddar like Gruyere, Swiss, Monterey Jack or provolone.
  • Store leftovers in an airtight container in the refrigerator and reheat in the microwave.

Here's how to make it: 

  1. Boil the potatoes in salted water in a large pot until just tender, about 15 to 20 minutes. Drain and return to pot. Over low heat, cook out the excess water.
  2. Add the butter, sour cream and milk. Over low heat, mash the potatoes until desired consistency. Season with salt and pepper. 
  3. Pour the potatoes into a shallow casserole dish. Top with the cheese. Bake in a preheated 350-degree F oven until cheese has melted, about 5 to 10 minutes. Garnish with chopped parsley or fresh chives, if desired.
