The Keg Mushrooms Neptune Copycat version


These mushrooms neptune are inspired by my favorite appetizer from The Keg restaurant. If you don’t know it or there isn’t one near you, I am telling you they are the best i’ve ever tasted. My family makes fun of me because whenever we go to the Keg I always order the exact same appetizer….ALWAYS. I love them that much, so much in fact that I decided I needed to make my own version. This recipe tastes as good or better (according to my husband) than the original. I do use fresh crab and fresh shrimp in my recipe but feel free to use canned, just omit the salt if you are using canned as they are both quite salty already.

You can make these on one big sheet tray or if you want a more elegant presentation then I suggest using what is typically known as an escargot dish. The indentations are also perfect for mushrooms and if you’re serving this at a dinner party then the presentation is impressive. I have linked below to the ones that I have.
