This is a recipe by the late Frank Davis of New Orleans WWL-TV, a larger than life personality and amazing cook. A cousin first cooked this for the family and everyone just raved over it. This is my version of this wonderfully filling whole meal casserole.
Don't let the list of ingredients scare you - prep everything ahead of time and have it at hand and the dish will all come together quickly. It's definitely worth the effort.
1In a pot with a spoon full of salt, and 1/2 tsp liquid crab boil, cook the potatoes until done. Let cool enough to handle and peel then chop into 3/4" to 1" pieces.
2Put potatoes, mushrooms, green onions into a deep baking pan and sprinkle with Creole seasoning. Set aside.
3In a medium bowl add cream cheese, sour cream, shrimp soup, cheddar cheese and mix until well blended. Set aside.
4In a large and deep skillet, or Dutch oven melt together the butter and olive oil over high heat.
5A handful at a time, begin dropping in the shrimp - don't over crowd the pan. Stir and saute them only until they turn pink - *DON'T let them render out their juices.
6As soon as they loose their gray color, take a strainer spoon and remove them temporarily to a bowl and set aside. Continue until all shrimp are done.
7Reduce heat to medium and add the onions, celery, carrots, bell pepper and sausage (broken into small pieces). Once vegetables start to soften add garlic and saute until vegetables are soft and thoroughly wilted. When sausage is cooked, spoon out some of the rendered grease and discard.
8Reduce heat to medium low and add the shrimp to the vegetables and mix well. Begin folding in the cream cheese mixture along with enough half & half to keep the mixture fairly liquid. Taste and add salt & white pepper to taste. The potatoes will absorb the liquid while baking.
9Pour this mixture over the potatoes in the baking pan, and gently work it into the potato & mushrooms until blended.
10Evenly layer the lump crabmeat over the potato mixture and gently press it down into the mixture, being careful not to break up the lumps.
11Spread the Parmesan or Gouda over the mixture then sprinkle the crushed potato chips over the cheese.
12Bake at 350* F, on middle rack, until the sides are hot and bubbly and the cheese is light brown and crusty, 45 minutes. Garnish with fresh minced parsley.
