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.

True to form, I used a big can of French fried onions on top of my mashed potato bake. This dish was delicious. My DD ate it and asked for more...Thanks for sharing KITTENCAL! Made for Let's P-A-R-T-Y December cooking event 2009.

Loved this recipe! I used up left over mashed potatoes, it was very easy to prepare. We didn't have french fried onions, and didn't need them. This is great even without that topping. I've already made this several times. Thanks so much for sharing!
