I'm unfortunately very surprised at all of the great reviews this dish has received. It definitely isn't anything special, I'm sorry to say. :(

Very good. I didn't have two cups of parmesan so I used one cup of grated cheddar and one cup of parmesan. Still excellent!

Easy and quick to make. Everybody ate is up and asked for more!

I made this as a Thanksgiving appetizer. I used 1 c. mayo, 8 ounces cream cheese, 1 c. parmesan cheese and 2 c. onions. I didn't have enough parmesan cheese and the recipe turned out great! Everyone loved it and could not stop eating it!

This was a HUGE disappointment. Because of the obvious fat content, I used low-fat mayo and low-fat swiss. I still ended up using a good 12-14 paper towels to soak up part of the grease it produces. (Not all, just part!) After all that effort, the flavor is NOT that great. It was a terrible disappointment, and I certainly will not make it again! Sorry.

There is a good recipe in here somewhere, but this isn't quite it. I used grated parmesan cheese from a container, and the dip had a grainy texture and was also very greasy. It did taste good though. I tried the same recipe using swiss cheese, cutting back on the mayonnaise--texture was better, but was still very greasy. I may tinker with this some more--perhaps a mixture of swiss cheese and cheddar cheese with a sprinkling of parmesan on top, more onions, cutting back still more on mayonnaise and substituting sour cream or cream cheese?

I have made this recipe many times but on a loaf of french bread split in half, then cooked in the oven until bread is toasted and spread is melted and golden. Never thought to use it as a dip ;-) Great on bread too!!! Always a favorite at any get together!

This is the best and easiest dip EVER! Great for parties . . . your guests will love you for it!

Dont you just hate when people say... "Well, I changed this and I changed that and it was just okay for me - then they give it a bad rating?" Yeah, I hate that too. This was a great dip! Simple, quick and delicious. Thank you so much :)

Excellent and beyond easy! I made in a split second and my guests loved it. I will make again and again!

After reading most reviews, I to made changes. I used (1) 8oz cream cheese, 1 cup sour cream, and 1/2 cup mayo. I made this for a birthday party. Most people were reluctant to try it, but once they did, they couldn't stop eating it. Some even put it on their hotdogs! A big hit, will make again!

Not wild about this recipe

Nice subtle onion flavor. Very moist. Good reheated. A hit at the birthday party!

I made this dip using the 8 oz cream cheese in exchange for 1c of the mayo. Also used only one cup of onions. Turned out great. Didn't take long to disappear both times that I've made it.

Very tasty and sweet. I chopped the onions in a hand crank food processor to get the peices small enough. They cooked right through in the oven and weren't crunchy. Makes for bad breath, but I would make it again for sure.

This dish is so yuumy. We served it at your holiday party and many of our guests asked for the recipe.

I just made this. It is out of this world delicious! The only problem I see with it is it is a little greasy, but taste fantastic.
