  1. Preheat the oven's broiler and set the oven rack about 6 inches from the heat source.
  2. Melt 1/2 cup of butter in a large skillet over medium heat. Stir in the green onions and mushrooms, and cook until the mushrooms have softened, about 5 minutes. Stir in the shrimp and walleye; cook and stir until the shrimp have begun to turn opaque, about 2 minutes. Add the lobster and crab, and cook a few minutes to heat.
  3. Stir in the sherry and white wine. Bring to a simmer, and cook for 2 minutes. Once the shrimp and walleye are no longer translucent in the center, stir in the cream of shrimp soup, half-and-half, 1 cup bread crumbs, and Cheddar cheese until the cheese has melted, and the mixture is bubbly. Pour into a casserole dish, and sprinkle evenly with 1/2 cup breadcrumbs and the Parmesan cheese. Dot with the pieces of cold butter.
  4. Cook under the preheated broiler until the butter has melted and the bread crumbs are golden brown.

I made this for a party of 12 and it was delicious. I added some other flavors like one garlic clove, shallots, cayanne and parsley. I used 4 2lb Maine lobsters, lumb crab and small shrimp. I followed the calculations for 12 and had enough left over for another 4 people. Delicious and impressive.

I used all walleye, and it worked well! The combination of seafood would be good too (I'm sure), but in case you only have 1lb of shrimp or 1lb of fish... I would still recommend you give this recipe a try. Very rich dish. Salt and pepper added at the table made it perfect.

Absolutely DELICIOUS!! My husband loved it! Used 1/2 shrimp and 1/2 lobster, cooking sherry and vermouth. Served over rice with green beans. Will definitely make again.
