I saw Paula Deen make these on television today. If you can't find party rye you can cut regular size bread into fourths. These can also be served at room temperature.

Ingredients Nutrition


  1. In a bowl, stir together the mayonnaise, Parmesan, mushrooms, and onion rings. Spread on lightly toasted party rye or pumpernickel.
  2. Place the canapes on a baking sheet and broil until the topping is bubbly.

A tasty treat. I doubled the recipe, sauteed and chopped about 5-6 oz. of Baby Bella mushrooms instead of using canned mushrooms, which, to me, don't have much flavor. Also forgot to toast the party pumpernickel first but it didn't seem to matter. I made the spread early in the day and assembled later. Quick and easy. Thanks, from Janet

These were very tasty. My husband prefered the ones that came out more toasted. I also used a 4 oz can of mushrooms and still thought the mayo was a bit heavy. I will make these again with even less mayo and some fresh sauteed mushrooms. It tasted like I was eating french onion soup with mushrooms. Maybe put a little slice of swiss cheese on top? Yum!

We must have all been watching the same episode! I too was eager to try this and today I did. They were excellent--not only in appearance, but taste as well. I do agree with other reviewers that there was a bit too much mayo (maybe not in Paula's eyes!;). Next time I make these I will reduce the mayo by just a smidge. I also will be adding garlic powder as I am a big fan of garlic. I also used Asiago cheese instead of Parm (had on hand) and it was delish. Overall, an excellent recipe! They were a hit at the Christmas party! Thanks for posting, Cookiedog!
