This was TERRIBLE!!! The mayo just left unseasoned (with the exception of saltiness from the parmesan) baked onion sitting in a huge pool of oil. I can see playing with this and using cream cheese instead of mayo, maybe adding crab or something. This was a waste of time and terrible.
Needed a few changes for my tastebuds but overall delicious. Too salty with the parm and mayo. I’ll try half cheddar, less mayo and a bit of water, and add some poultry herbs for more flavour next time.
So simple, so delicious, and so different! Everyone loved it and wanted the recipe:-)
Great Dip!
I made this for a family get together and it was gone fast. Very easy and simple to make. Family has asked me to make it for every get together
Has anyone ever made this for large parties? Was wondering if I need to do two seperate bowls/crocks,or if I could triple the recipe and just cook it longer. Any advice. Thanks,
So good!! Definite favorite for holidays or get togethers!
Now who doesn’t have onion, mayo and parm. cheese in their kitchen. So no excuses for making a simple and delicious appetizer! I always use sweet onions, preferably Vidalia. Every time I have made it, the whole dish disappears. It is so good and easy. Be sure to serve it while it is hot. Goes well on crackers or toasted baguette slices.
We’ve used this recipe to demonstrate the family farm’s sweet onions at markets and trade shows. The recipe really needs very sweet onions, such as Vidalia, WallaWalla, PA Sweets, etc. The recipe takes well to low-fat mayo, and we often use grated low-fat Jarlsberg mixed with a little Parmesan. A teaspoon or more of a no-salt herb blend (such as Ms Dash, Spike, etc) really jazzes up the flavor. Just blot off any fat that rises to the surface. We’ve had people ask to buy the extra pans of dip. Sells a lot of onions!! And if there are any leftovers, it makes a great scalloped potato casserole addition.
I make this with shredded cheddar. It’s fabulous. Always a hit at a party.I dice the onions into small peices and I don’t spray the pan. As for being “oily”, I think that’s what keeps it nice and smooth even after 2 hours out of the oven, if it lasts that long!
This is great as a dip but I took it and added imitation crab meat plus a little Tony Chacherie’s. Then I baked some fish coated with Italian bread crumbs and served the fish with the “dip” on top. AWESOME!
This is such a hit! I am asked to bring it back over and over. I like to carmelize the onions before adding to the mayo. & cheese & then bake the dip in a crusty bread bowl. Don’t overcook and you’ll have virtually no oil!
Was first introduced to this dip many years ago by my friends in England. Have made it for many occasions, and everyone loves it.
This recipe is easy to make and usually one of the first gone. I serve it any time we entertain a large crowd. Try it with Swiss Cheese instead of Parmesan…YUMMY!
We thought this was just ok. I made half a recipe. I won’t make it again, but it was good idea.
This dip was DELICIOUS!!!!! My husband can’t eat mayonnaise so instead I put in 1 8oz. package of low-fat cream cheese and 1 cup of sour cream and served it with homemade sweet bread, it turned out perfect and everyone loved it.
Wonderful- halved the recipe for 6 with leftovers- great with whole wheat taco chips I used half light mayo and half light sour cream and there was no grease
I halved the recipe for a small group and used reduced fat olive oil mayonnaise. I also found I was out of parmesan, so I used cheddar. It was still wonderful, gobbled up by everyone, and not greasy in the slightest.
little too much onion…
Great dip if you like onions!
We loved this although we did make only enough for six people it was still amazing. I used the exact proportions for fewer people and cooked for 20 minutes. Even after that short a time there was a ton of oil. I just poured off as much as possible. Because of that I’m not sure I would make it again. Thanks.
