I make this constantly, so much so that my family has asked for a reprieve, but I will pass along my tips: Some of the bags of cubed hashbrowns they sell are no longer 2 lbs. so check carefully. I find generic to be the best. I use a 2c. bag of sharp cheddar in place of the american cheese; any cheese will work, but we prefer the sharper flavor. I too cut back on butter, it's just not necessary. I nuke the potatoes for about 10 minutes alone or thaw them in the fridge overnight for a creamier consistency. For brunches, I use O'Brien potatoes (hash browns with the potatoes and onions and peppers already added), use cream of potato instead of chicken and add a pkg of precooked bacon crumbled up. Yum, people rave over that for breakfast!

This was a pretty tasty recipe, but I didn't like it enough to serve at a gathering, it's nothing special. It's fine for home, although I don't know if I'd make it again. My only big complaint is that I checked the back of the hash brown pototes bag (I thought I spotted a new recipe to try) and I did spot a recipe - this very SAME one! The only difference was they asked for 1/4 cup butter, not 1/2, it had the corn flake topping and everything. Picky hubby said it was pretty good.

I have used this recipe for several years for a side dish at dinner or for brunch. One thing I do to make life easier is to put the sour cream, soup, cheese (cut in large chunks) and onions in the food processor and chop away. This saves the time that it would take to grate cheese and mince onions.

This recipe is so simple and delicious it is insane! I have made it 3 times now and to each meal it has been perfect. It is an inexpensive, easy addition to a meal, or a quick and simple main course with a salad (vinegrette dressing would be ideal. Give it a go.. it's yummy!

I've used a version of this recipe for years. I generally use frozen hash browns and when in a real pinch, frozen chopped onions and pre-shredded cheese. You can mix it up and throw it in the oven while you're dressing and within the hour you're out the door to your next 'do. For a quick brunch or light dinner, add cubed ham and broccoli florets. A wonderful, family-friendly one-pan dish.

I love this recipe...it's so easy. One time I was in a real hurry...I had no sour cream and I had no onions. So, instead of the sour cream, I added a can of cream of mushroom soup and mixed it in the blender with the other soup and some milk and substituted that. I also used dried onion flakes. I actually enjoyed it this way and have changed my recipe so I'll make it the same way each time.

This was good. I agree with some of the other reviewers, that there was too much butter. There was a small lake of butter at the bottom of the dish. Just cut back a little on that and it's wonderful.

Decadent and YUMMIE! How could it be bad with all the creamy buttery goodness? I can't follow a recipe so I subbed O'Brien potatoes that have onion and green pepper so I wouldn't have to cut up the onion. Also used Cheddar instead of american cheese. Delicious!
