"Not a fan on this one. Dry and the potatoes were grainy."

"We really enjoyed this for breakfast this morning, and I will definitely make it again. The only improvement that I can think of is breaking up the potato's a little dense. So the next time I make this casserole, I'll split the ingredients and do two series of layers. I think that will make a better distribution of flavors as well."

"I have NO CLUE where positive ratings for this recipe are coming from. The addition of milk to the eggs and raw overly processed "potatoes" out of the freezer makes for a spongy, slightly watery, texture. I think this recipe can be improved upon greatly, but not without work. The hashbrowns need to be cooked - even though they are overly processed and frozen. The hashbrowns should also be tossed with the ham and green chiles. Layering does not work. With that said, the cheese should be mixed in with the egg to distribute evenly. In addition to that, I understand the reason for using milk to cut the fat in an already overly fattening food, but seriously, you need to use at least half & half to get a good texture. The texture IS NOT working for this dish. I really had high hopes for this recipe and am greatly disappointed."

"This is a stand-by at our house. I make it for brunch potlucks and for dinner. I usually use about 1 pound of frozen potatoes and 2 cups cheddar cheese. Regular milk works just as well as the evaporated."

"I love, love, love this recipe!!! I have made it several times using bacon or sausage instead of ham and it turns out really good but there is something with the ham that makes it excellent.

My favorite to make for guests."
