Preheat the oven to 375 degrees F. Pour the potatoes, sour cream, salsa or enchilada sauce, shredded cheese, and chicken base in a 3 quart baking dish. Mix well, and spread out evenly.
Place the cornflakes in a plastic zip bag. Zip closed and crush the corn flakes. Then pour in the melted butter and toss to coat.
Sprinkle the buttered cornflakes evenly over the top of the potatoes. Cover the pan with foil.
Bake covered for 45 minutes. Then remove the foil and bake another 10-15 minutes, until bubbly. Serve warm.
