    Have you ever been to Keg’s Steakhouse and tried the famous Mushrooms Neptune appetizer?? Well if not, now you can try this recipe in the comfort of your own house!

    Years ago, when I first made these, I thought they would be good, but I didn’t realize HOW good they would be!

    After trying to original recipe at the restaurant, I decided to scour the internet and look for ideas/inspiration to recreate the dish.

    Creamy, flavorful stuffed mushrooms with shrimp and crab meat in every bite! Perfect as an appetizer, snack, or side dish option!

    After a few trials, these creamy, flavor packed mushrooms came about and if I am being honest, they may even be BETTER than the original.

    I prepared a huge batch and brought them to a neighborhood get together a while back. Not only was the plate cleared in a matter of a few minutes, but I cannot tell you how many people requested the recipe right then and there. Since then, all I have officially been in charge of bringing an appetizer to parties/gatherings and this is one that is always expected!

    Check out these other great appetizer options:

    Smoked Deviled Eggs

    ULTIMATE Texas Twinkies

    Sometimes, on a weekend afternoon, my hubby and I like to prepare a few different appetizers and simply use them as our meal throughout the afternoon. Changes things up, allows us to come and go, and who says you need to have a party or go somewhere to enjoy an appetizer, right?!!

    Ingredients Needed for this Mushroom Neptune recipe:

    Cream cheese

    Sour cream

    Swiss cheese

    Garlic clove, crushed

    Shrimp

    Crabmeat

    Green onion, chopped

    Pepper

    Mushrooms

    How to prepare:

    Combine- all ingredients.

    Mix well- until blended and fill mushroom caps. (Piping the caps with a pastry bag is a nice touch.).

    Bake- at 375ºF for 15 minutes or until slightly browned. Serve and enjoy!
