I'm good friends with the the submitter of the recipe and the site gave the wrong proportions,much to her alarm. You make this with 2 cups mayo, 2 cups shredded swiss cheese and 2 cups vidalia or any sweet onion (NOT all those onions it says to use!!!)No wonder some people thought it was nasty. It's to die for when it's made correctly! I hope those people who had bad experiences will try it again.

GREASY, GREASY, GREASY! I was very embarrased last night when this came out of the oven in front of all of my guests. Everyone kept asking how much butter I put into the dip. This dip was nothing but a huge puddle of grease. The ingredients seperated and it was just a mess. Needless to say, I had TONS left because no one really wanted to eat a big pile of greasy mess.

We could not stop eating this dip! Next time I will put it into a crock pot to keep warm throughout the party. I substituted 8oz (1 brick) of cream cheese for half the mayo and used both parmesan (FRESHLY GRATED - not powdered ) and swiss cheeses. The parmesan added a nice kick of flavor and I think that all swiss would have been too bland. Be sure to chop the onions medium-fine or it takes a lot longer for the onions to cook.

I got a variation of this recipe from my good friend Karen and I love it! She uses: 3 onions, 2 c mayo, 2 c shredded swiss, 1 8 oz can choped water chestnuts, 1/4 c dry white wine, 1 minced garlic glove, 1/2 tsp hot sauce. It is a fabulous recipe. There is always a crowd hovering over this dip at parties.

A friend of mine calls this recipe "Cuppa, Cuppa, Cuppa" as in "a cup of Vidalia onions, a cup of mayonnaise, a cup of swiss cheese." (Or in this recipe's case, two cups of each!) I made this last night for Monday Night Football and it was a crowd favorite! Use a sturdy cracker for this dip - - regular tortilla chips just snapped when you scooped. Can't wait to try the leftover reheated tonight!

I've been making this a party staple ever since snagging the recipe from a friend years ago. This is THE BEST and it's so easy. The rater who said "cuppa, cuppa, cuppa" made me laugh, because that's how I remember the recipe when I asked. Equal parts swiss, mayo, and sweet onions. I use light mayo and it's still yummy. Great w/crusty french bread.

Love this dip, use low fat Hellman's mayo instead of full fat and it won't be so greasy.

This was quick and easy to make. I ate this warm. I thought the 2 cups of mayo was going to be too much so I added more like 1.5 cups and it was great. Thanks for the quick and easy recipe.
