Step 1

In a large bowl, stir together the sour cream, cream of mushroom soup, half of the melted butter (1/4 cup), salt, pepper, garlic powder, onion powder, cayenne and grated cheese.

Step 2

Then stir the (frozen) potatoes into this mixture.

Step 3

Lightly grease a 9×13 baking pan. Add this mixture to the pan, spreading evenly.

Step 4

In a gallon-sized ziplock bag, crush the corn flakes and then toss in the remaining melted butter. Sprinkle this over the potato layer.

Step 5

Cover the dish in aluminum foil and bake at 350°F (177°F) for 45-50 minutes in total.

Step 6

After the first 25 minutes, remove the aluminum foil for the remainder of the bake time.

Step 7

When done, the top will look golden and crunchy. Sprinkle the green onions over the top before serving.
