Step-by-Step Method
Boil the potatoes
Peel the potatoes and cut into large chunks. Boil in salted water until tender, then drain well and return to the pot.
Mash until creamy
While the potatoes are hot, add the butter and mash. Stir in the sour cream a little at a time until you get a smooth, spoonable texture. Season with salt and pepper if you like.
Add the cheeses
Mix in part of the cheddar and the colby-style cheese, saving a handful of cheese for the top.
Assemble the casserole
Spread the mixture into a lightly greased baking dish. Sprinkle the reserved cheese evenly over the surface.
Bake and serve
Bake at 180°C / 350°F until the top is melted and lightly golden, about 20–25 minutes. Let it sit for 5 minutes, then serve warm.
