Recipe Instructions

Step 1

Set an oven rack about 6 inches from the heat source and preheat the oven's broiler.

Step 2

Melt 1/2 cup butter in a large skillet over medium heat. Add mushrooms and green onions; cook and stir until mushrooms softened, about 5 minutes. Stir in shrimp and walleye; cook and stir until shrimp begin to turn opaque, about 2 minutes. Add lobster and crab; cook until heated through, about 3 minutes.

Step 3

Stir in white wine and sherry; bring to a simmer and cook until shrimp and walleye are no longer translucent in centers, about 2 minutes. Stir in 1 cup bread crumbs, soup, half-and-half, and Cheddar cheese until cheese melted and mixture is bubbly. Transfer to a casserole dish; sprinkle evenly with remaining 1/2 cup bread crumbs and Parmesan cheese. Dot with cold butter.

Step 4

Cook under the preheated broiler until butter has melted and bread crumbs are golden brown.
