This is a great way to use up any left-over mashed potatoes....goes wonderful with any meal....just mix and bake, so easy to prepare.

We think leftovers don't keep very well as the onion topping becomes soggy and the flavors are "off" when reheated. Wonderful when it's freshly made, however. :) ***March 2010 Review: I originally received this recipe from my pastor's wife, and it was titled Puffy Potato Casserole. I used prepared mashed potatoes (that already had butter, salt, pepper, and milk added in) probably a little more than 3 1/2 cups. Also, the original recipe I have said to bake at 350 for 50 minutes (I did 375 for 20 minutes since I had other items in the oven). It came together easily, and everyone enjoyed it.
