Hi! I'm Mary, the person who sent in the recipe. I read some of the reviews and I hope people understood that the onion dip used is the ready made kind that you buy in the refigerated section of the grocery store. I use an 8 ounce container. It is not the dry soup mix.

Good but not great. I liked that I could make it ahead of time and keep in the fridge until needed.

I made this casserole yesterday (with a couple of changes), and it was delicious! Instead of the onion dip, I combined a package of Ranch Dressing mix with an 8-ounce carton of sour cream and sprinkled the top of the casserole with French-fried onions in lieu of using the margarine.

I opt. for 8 oz light sour cream vs. the onion dip. Also use light cream cheese and cut the butter down to 1/4 a cup...I have had it all different ways, very yummy and much faster than cubing/boiling etc!

Love this! I'm weird- I like instant mashed potatoes better than real! So I knew I had to try this recipe. After reading the reviews, I decided to use 1 1/3 c. milk. It worked out great. Baked 30 min. I also used my electric mixer to blend the cream cheese mixture, as well as after putting it all together. I might try the sour cream/onion powder thing next time to make it totally smooth. But it's terrific the way it is!UPDATE: I used 3 cups of water & 1 1/2 c. milk this time. I also put the dip, eggs, & cream cheese in the blender to make it smooth! Even better this way!

My family couldn't get enough of these potatoes! I sub'ed sour cream for cream cheese as some others did and used prepared onion dip right out of the dairy case at the grocer. I thought it would make the dish "soupy" but it didn't and the potatoes weren't dry as some others mentioned. Added a sm. can of french fried onion rings (crushed) to the top, melted butter and poured over. Delish! Next time I'll make sure to have cream cheese on hand. I'm anxious to see if the potatoes come out creamier. Thanks, Mary. This is a keeper!

I've made this several times now, and it never lasts long. Rather than 8 oz. of onion dip, I just use a 1.5 oz. packet of dry onion chip dip mix. This is a delicious side dish, thanks for the recipe!

I made this recipe for a large family Christmas gathering. It was very good and everyone kept going on about how good it was. The only bad thing...the recipe calls for one "PACKAGE" of onion dip. That confused me and I accidentally bought a small package of the "make your own dip". The recipe should read...1 8oz "CONTAINER" onion dip. Other than that, it was a great hit and I'll make it again.
