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.


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.
